A. The volume of the hemisphere with a diameter of 48 yards is approximately 1001.1 cubic yards.

B. The volume of the sphere with a circumference of a great circle approximately equal to 26 meters is approximately 359.4 cubic meters.

A. To find the volume of a hemisphere, we first need to calculate the radius. The diameter is given as 48 yards, so the radius is half of that, which is 24 yards.

The formula for the volume of a hemisphere is (2/3)πr^3, where r is the radius. Plugging in the values:

Volume = (2/3) * π * (24^3)

Volume ≈ 1001.1 cubic yards (rounded to the nearest tenth)

Therefore, the volume of the hemisphere is approximately 1001.1 cubic yards.

B. To find the volume of a sphere, we need to know the radius. Since the circumference of a great circle is given as approximately 26 meters, we can use the formula C = 2πr, where C is the circumference and r is the radius.

We can rearrange the formula to solve for the radius: r = C / (2π). Plugging in the circumference:

r = 26 / (2π)

r ≈ 4.134 meters (rounded to the nearest thousandth)

The formula for the volume of a sphere is (4/3)πr^3. Substituting the radius:

Volume = (4/3) * π * (4.134^3)

Volume ≈ 359.4 cubic meters (rounded to the nearest tenth)

Therefore, the volume of the sphere is approximately 359.4 cubic meters.

Find an equation of the line that passes through (2, -2) and parallel to the line passing through (4, 5) and (6, 4).

Answers

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the second line

[tex](\stackrel{x_1}{4}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{4}) ~\hfill~ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{4}-\stackrel{y1}{5}}}{\underset{\textit{\large run}} {\underset{x_2}{6}-\underset{x_1}{4}}} \implies \cfrac{ -1 }{ 2 } \implies - \cfrac{1}{2}[/tex]

so we're really looking for the equation of a line whose slope is -1/2 and it passes through (2 , -2)

[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{-2})\hspace{10em} \stackrel{slope}{m} ~=~ - \cfrac{1}{2} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-2)}=\stackrel{m}{- \cfrac{1}{2}}(x-\stackrel{x_1}{2}) \implies y +2 = - \cfrac{1}{2} ( x -2) \\\\\\ y+2=- \cfrac{1}{2}x+1\implies {\Large \begin{array}{llll} y=- \cfrac{1}{2}x-1 \end{array}}[/tex]

Answer:

Line passing through (4, 5) and (6, 4):

[tex]m = \frac{4 - 5}{6 - 4} = - \frac{1}{2} [/tex]

Line passing through (2, -2) and with slope -1/2:

-2 = (-1/2)(2) + b

-2 = -1 + b, so b = -1

y = (-1/2)x - 1

-2y = x + 2

-x - 2y = 2

x + 2y = -2

Mahmud Mahtab company's shareholders equity December 30.2020 are given below-

Sources of equity capital Common stock (Tk.100par 30.000 shares) = 30,00,000 TK, Additional paid up capital = 15,00,000 TK, Retained earnings = 55,00,000 TK,
Shareholders total equity = 1,00,00,000 TK.

The price of the stock on December 30 was Tk.500, On December 31,2020 Mahmud Mahtab declared:

(1) 10% stock dividend.
(2) 2 for I stock split.
(3) 1 for 5 reverse stock split.

REQUIREMENT :

What would happen to the accounts for the above decision?​

Answers

1) 10% stock dividend: Increase in shares, no change in equity value.

2) 2 for 1 stock split: Doubles shares, no change in equity value.

3) 1 for 5 reverse stock split: Decreases shares, no change in equity value.

The decisions made by Mahmud Mahtab regarding stock dividend, stock split, and reverse stock split would result in the following changes to the accounts:

1) 10% Stock Dividend:

A stock dividend is a distribution of additional shares of stock to existing shareholders. In this case, a 10% stock dividend means that for every 10 shares held, shareholders will receive an additional share. As a result, the following changes would occur:

- Common stock: The number of shares would increase by 10% (3,000 additional shares).

- Additional paid-up capital: There would be no change.

- Retained earnings: There would be a reduction of the amount equal to the market value of the shares issued as dividends.

2) 2 for 1 Stock Split:

A stock split involves dividing existing shares into a larger number of shares. In a 2 for 1 stock split, each existing share would be split into two shares. The following changes would take place:

- Common stock: The number of shares would double (60,000 shares).

- Additional paid-up capital: There would be no change.

- Retained earnings: There would be no change.

3) 1 for 5 Reverse Stock Split:

A reverse stock split combines a number of existing shares into a smaller number of shares. In a 1 for 5 reverse stock split, every five shares would be consolidated into one share. The accounts would be affected as follows:

- Common stock: The number of shares would decrease by 80% (24,000 shares).

- Additional paid-up capital: There would be no change.

- Retained earnings: There would be no change.

Note: The above changes would affect the number of shares and their par value, but the total shareholders' equity (1,00,00,000 TK) would remain unchanged.

New flowers are being planted in an empty area of a landscaped garden. The
map shows the area that is being planted. If walkway A and walkway B are
parallel, what is the distance from F to G on walkway C?

Answers

The distance from F to G on walkway C is approximately 19.21 units.

To determine the distance from point F to point G on walkway C, we can use the information provided in the map and apply some basic geometric principles.

Looking at the map, we can see that walkway A and walkway B are parallel. Let's use this information to find the distance from F to G on walkway C.

First, let's identify the relevant points on the map. We have point F on walkway C and point G on walkway C. The map also shows two intersecting lines, representing walkways A and B, but we don't need to consider those for this particular calculation.

To find the distance from F to G on walkway C, we need to focus on the segment of walkway C that connects F and G. Based on the map, we can see that the segment of walkway C is perpendicular to both walkway A and walkway B.

Since walkway A and walkway B are parallel, and the segment of walkway C is perpendicular to both, we can conclude that the segment FG forms a right triangle with walkway A and walkway B.

In a right triangle, we can use the Pythagorean theorem to find the length of one side (FG) if we know the lengths of the other two sides.

Let's assume the length of the segment FG is represented by the variable 'd' (which we need to find).

From the map, we can see that the distance from F to walkway A is 15 units. Similarly, the distance from G to walkway B is 12 units.

Applying the Pythagorean theorem, we have:

d^2 = 15^2 + 12^2

d^2 = 225 + 144

d^2 = 369

Taking the square root of both sides, we find:

d ≈ √369

d ≈ 19.21

As a result, it takes 19.21 units to get from F to G on walkway C.

work out how mnany bisuits she can make

Answers

Therefore, Heather can make a maximum of 4 biscuits with the given ingredient quantities.

To determine how many biscuits Heather can make, we need to compare the amount of each ingredient required for a single biscuit to the total amount of ingredients she has.

Let's calculate the number of biscuits she can make based on the ingredient quantities provided:

First, we need to find the ratio of each ingredient required per biscuit:

Flour: 100g per biscuit

Butter: 120g per biscuit

Icing sugar: 80g per biscuit

Chocolate: 25g per biscuit

Next, we divide the total amount of each ingredient by the respective ratio to find the maximum number of biscuits she can make:

Flour: 2kg / 100g = 20 biscuits

Butter: 1kg / 120g = 8.33 biscuits (approximately)

Icing sugar: 340g / 80g = 4.25 biscuits (approximately)

Chocolate: 200g / 25g = 8 biscuits

Since we can only make a whole number of biscuits, the limiting factor is the icing sugar. Heather can only make 4 biscuits since she has 4.25 times the required amount of icing sugar.

What are the domain and range of the function f(x) = -log(5-x)+9?

Answers

The domain of the function is all real numbers less than 5, and the range is all real numbers greater than or equal to 9.

The given function is f(x) = -log(5-x) + 9.

To determine its domain and range, we need to consider the restrictions on x and the possible values of f(x).

Domain:

The domain refers to the set of all valid inputs or values of x for which the function is defined.

In this case, the function contains a logarithmic term, -log(5-x), which is only defined for positive values inside the logarithm.

Therefore, we must ensure that the expression 5-x is greater than zero:

5 - x > 0

Solving this inequality, we find:

x < 5

Hence, the domain of the function is (-∞, 5).

Range:

The range refers to the set of all possible output values or values of f(x). Since the logarithm term can take any positive value, and we add 9 to it, the range of the function is shifted upward by 9 units.

The range can be defined as all real numbers greater than or equal to 9:

Range: [9, +∞)

To summarize, the domain of the function f(x) = -log(5-x) + 9 is (-∞, 5), and the range is [9, +∞), indicating that f(x) can take any value greater than or equal to 9.

Rounded to the nearest tenth of a percent, the probability is approximately 27.8%.

To determine if the event of rolling a pair of dice and getting doubles or a sum of 6 is mutually exclusive, we need to assess whether the two outcomes can occur simultaneously or if they are mutually exclusive.

Let's analyze the two outcomes separately:

1. Getting doubles: When rolling a pair of dice, getting doubles means that the numbers on both dice are the same. The possible outcomes for getting doubles are (1,1), (2,2), (3,3), (4,4), (5,5), and (6,6). There are a total of 6 outcomes that satisfy this condition.

2. Getting a sum of 6: To get a sum of 6, the numbers on the two dice should add up to 6. The possible outcomes for this condition are (1,5), (2,4), (3,3), (4,2), and (5,1). There are a total of 5 outcomes that satisfy this condition.

Now, to determine if the two outcomes are mutually exclusive, we need to check if there are any outcomes that satisfy both conditions. In this case, the outcome (3,3) satisfies both conditions (doubles and sum of 6).

Since there is one outcome that satisfies both conditions, we can conclude that the event of rolling a pair of dice and getting doubles or a sum of 6 is not mutually exclusive.

To find the probability of this event, we need to determine the total number of possible outcomes when rolling a pair of dice. Each die has 6 sides, so there are 6 possible outcomes for each die, resulting in a total of 6 * 6 = 36 possible outcomes when rolling a pair of dice.

The probability is calculated by dividing the number of favorable outcomes (satisfying the condition) by the total number of possible outcomes.

Favorable outcomes = 6 (for doubles) + 5 (for sum of 6) - 1 (for the overlapping outcome) = 10

Probability = Favorable outcomes / Total number of outcomes = 10 / 36 ≈ 0.2778

Rounded to the nearest tenth of a percent, the probability is approximately 27.8%.

A tangent is a straight line that touches a circle at only one point.

The given diagram shows a circle with three points of tangency: S, T and U.

According to the Two-Tangent Theorem, if two tangents to a circle meet at one exterior point, the tangent segments are congruent.

The exterior points are P, Q and R. Therefore, the congruent segments are:

[tex]\overline{PS} = \overline{PT} = 9[/tex]

[tex]\overline{QT} = \overline{QU} = 4[/tex]

[tex]\overline{RS} = \overline{RU} = 13[/tex]

To find the value of x, use the equation PS = PT:

Total number of vehicles = 260

Cost of each commercial van = $25,000

Cost of each small truck = $50,000

Cost of each large truck = $50,000

Let

c = commercial van

s = small truck

l = large truck

v = 2s

s = l

So,

v + s + l = 260

2s + s + s = 260

4s = 260

divide both sides by 4

s = 260/4

s = 65

Therefore,

Mr. John recently bought 2 cords of wood from a local contractor
(delivered in a dump truck). After the pile was dropped off, he stacked
the wood and wondered if he really received the 2 standard cords of
wood (see diagram) or if the company sold him less wood than he
ordered.

Note: a cord of wood if defined as 4ft X 4ft’ X 8ft stack
Mr. John ended up stacking to piles of wood this past week.
Mr. John ended up with two piles of wood with the following sizes

PILE #1: 72” X 167” X 16”
PILE #2: 65” X 266” X 16”

QUESTIONS:
1. Did Mr. John get more or less than 2 cords of wood (as defined in
the diagram above)?
2. If a standard piece of wood is 5” X 5” X 12”. How pieces of actual
wood did he receive based on his stacked piles?
3. If the cost for both cords of wood was actually $250/cord,
What was the cost per a standard piece of wood?

Answers

1. Mr. John received more than 2 cords of wood based on the sizes of the stacked piles.

2. Based on the stacked piles, Mr. John received approximately 11,974 pieces of actual wood.

3. The cost per standard piece of wood is approximately $0.0417.

1. To determine if Mr. John received more or less than 2 cords of wood, we need to calculate the volume of each pile and compare it to the volume of a standard cord of wood.

Calculating the volume of each pile:

PILE #1:

Volume = 72 inches * 167 inches * 16 inches = 1,523,584 cubic inches

PILE #2:

Volume = 65 inches * 266 inches * 16 inches = 2,068,480 cubic inches

Calculating the volume of a standard cord of wood:

Volume of a standard cord = 4 feet * 4 feet * 8 feet = 128 cubic feet

Since 1 foot = 12 inches, the volume in cubic inches is 128 * 12 * 12 * 12 = 221,184 cubic inches.

Comparing the volumes:

Pile #1: 1,523,584 cubic inches

Pile #2: 2,068,480 cubic inches

Standard cord: 221,184 cubic inches

It is evident that both piles have significantly more volume than a standard cord of wood. Therefore, Mr. John received more than 2 cords of wood.

2. To determine the number of standard pieces of wood received, we need to calculate the number of pieces that can be obtained from the total volume of the piles.

Total volume of the piles = Volume of Pile #1 + Volume of Pile #2

Total volume = 1,523,584 cubic inches + 2,068,480 cubic inches = 3,592,064 cubic inches

Volume of a standard piece of wood = 5 inches * 5 inches * 12 inches = 300 cubic inches

Number of standard pieces of wood received = Total volume of the piles / Volume of a standard piece of wood

Number of pieces = 3,592,064 cubic inches / 300 cubic inches = 11,973.55 pieces (rounded to the nearest whole number)

Therefore, Mr. John received approximately 11,974 pieces of actual wood based on his stacked piles.

3. To calculate the cost per standard piece of wood, we need to divide the total cost of the two cords by the number of standard pieces received.

Total cost for both cords of wood = 2 cords * $250/cord = $500

Cost per standard piece of wood = Total cost / Number of standard pieces

Cost per piece = $500 / 11,974 = $0.0417 (rounded to four decimal places)

Therefore, the cost per standard piece of wood is approximately $0.0417.

X^2 + x -72 rewrite the giving expression

Answers

Answer:

(x + 9)(x - 8)

Step-by-step explanation:

Factorising the expression

x² + x - 72

consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (+ 1)

the factors are + 9 and - 8 , since

9 × - 8 = - 72 and 9 - 8 = + 1 , then

x² + x - 72 = (x + 9)(x - 8) ← in factored form

Answers

There can be multiple outputs (monthly charges) for a given input (number of credit cards), violating the definition of a function. hence, Situation 3 does not represent a function.

Situation 3: the total amount of money charged monthly on credit cards to the number of credit cards owned does not represent a function.

In a function, each input (or x-value) should have a unique output (or y-value). However, in this situation, the total amount of money charged monthly on credit cards depends on the number of credit cards owned. It is possible to have different credit card numbers but still have the same total amount of money charged monthly.

For example, two people could own different numbers of credit cards but have the same monthly charges.

As a result, the definition of a function can be violated by having many outputs (monthly charges) for a single input (number of credit cards).

Because of this, case 3 does not represent a function.

Find the missing side.
N
41° 15
Z=
Round to the nearest tenth.
Remember: SOHCAHTOA

Answers

Answer:

To the nearest tenth, we have,

z = 19.9

Step-by-step explanation:

The missing side is the hypotenuse,

And we are given the side adjacent to the angle,

z = hupotenuse = H = ?

Adjacent = A = 15

Angle = α = 41

Since we have to find hypotenuse and we are given adjacent,

Using SOHCAHTOA,

We know the angle and adjcent but need to find Hypotenuse,

So, we use CAH

or,

cos(α) = A/H

cos(α) = 15/z

(since z = hypotenuse)

zcos(α) = A

z = A/(cos(α))

z = 15/cos(41)

z = 19.8752

To the nearest tenth, we get,

z = 19.9

Answer:

C.  5x(-x + 2)

Step-by-step explanation:

To factor the expression -5x² + 10x, we need to look for a common factor that can be factored out.

Finding a common factor involves identifying a term or expression that can be factored out from each term of a given expression.

Both terms have the common factor of 5x, so we can factor out 5x:

5x(-x + 2)

Therefore, the factored form of -5x² + 10x is -5x(x - 2).

[tex]\hrulefill[/tex]

Additional notes:

If we expand the expressions in the given answer options, we get:

  A.  −5x(x + 2) = -5x² - 10x

  B.  5(−x² + 10x) = -5x² + 50x

  C.  5x(−x + 2) = -5x² + 10x

  D.  x(5x + 10) = 5x² + 10x

Hence confirming that the correct answer is option C.

A teaching hospital in South-West Part of Nigeria receives on the average 5 pregnant women with high blood pressure per week. What is the probability that on a particular week, the teaching hospital will receive:
1.) No high BP pregnant woman

Answers

Answer:

The probability that on a particular week, the hospital will receive on high BP pregnant woman is 0.0068

Step-by-step explanation:

We use the Exponential distribution,

Since we are given that on average, 5 pregnant women with high blood pressure come per week,

So, average = m = 5

Now, on average, 5 people come every week, so,

5 women per week,

so, we get 1 woman per (1/5)th week,

Hence, the mean is m = 1/5 for a woman arriving

and λ = 1/m = 5 = λ

we have to find the probability that it takes higher than a week for a high BP pregnant woman to arrive, i.e,

P(X>1) i.e. the probability that it takes more than a week for a high BP pregnant woman to show up,

Now,

P(X>1) = 1 - P(X<1),

Now, the probability density function is,

[tex]f(x) = \lambda e^{-\lambda x}[/tex]

And the cumulative distribution function (CDF) is,

[tex]CDF = 1 - e^{-\lambda x}[/tex]

Now, CDF gives the probability of an event occuring within a given time,

so, for 1 week, we have x = 1, and λ = 5, which gives,

P(X<1) = CDF,

so,

[tex]P(X < 1)=CDF = 1 - e^{-\lambda x}\\P(X < 1)=1-e^{-5(1)}\\P(X < 1)=1-e^{-5}\\P(X < 1) = 1 - 6.738*10^{-3}\\P(X < 1) = 0.9932\\And,\\P(X > 1) = 1 - 0.9932\\P(X > 1) = 6.8*10^{-3}\\P(X > 1) = 0.0068[/tex]

So, the probability that on a particular week, the hospital will receive on high BP pregnant woman is 0.0068

The measure of angle Q is given as follows:

m < Q = 70º.

What are supplementary angles?

Two angles are defined as supplementary angles when the sum of their measures is of 180º.

In a parallelogram, we have that consecutive interior angles are supplementary, hence the value of x is obtained as follows:

6x + 4 + 10x = 180

16x = 176

x = 176/16

x = 11.

Then the measure of angle Q is given as follows:

m < Q = 6 x 11 + 4

m < Q = 70º.

Humpback whales migrate up to 25,000 kilometers per year from polar waters to tropical waters. An observer
measures a humpback whale traveling a distance of 13.5 kilometers in 30 minutes.
What is the average speed of the humpback whale in km/h?

Answers

Average speed of the humpback whale: 27 kilometers per hour.

To calculate the average speed of the humpback whale, we can use the formula:

Average speed = Total distance / Total time

Given that the humpback whale traveled a distance of 13.5 kilometers in 30 minutes, we need to convert the time to hours. There are 60 minutes in an hour, so 30 minutes is equal to 0.5 hours.

Now, we can substitute the values into the formula:

Average speed = 13.5 kilometers / 0.5 hours

Average speed = 27 kilometers per hour

Therefore, the average speed of the humpback whale is 27 kilometers per hour.

However, if you provide me with the equation of the line in the slope-intercept form or describe the relevant details from the graph, I can certainly help you with a response within the given word limit.

The slope-intercept form of a linear equation is given by y = mx + b, where "m" represents the slope of the line and "b" represents the y-intercept, the point where the line intersects the y-axis.

Using this equation, you can determine the slope and y-intercept by comparing the given equation with the slope-intercept form.

Once you provide me with the equation or necessary information, I'll be able to assist you further in understanding the line and its characteristics.
