Answer:

cosΘ = [tex]\frac{\sqrt{21} }{5}[/tex]

Step-by-step explanation:

using the identity

• sin²Θ + cos²Θ = 1 ⇒ cos²Θ = 1 - sin²Θ

given Θ is in quadrant 1 , then cosΘ > 0

sinΘ = [tex]\frac{2}{5}[/tex] , then

cos²Θ = 1 - ( [tex]\frac{2}{5}[/tex] )² = 1 - [tex]\frac{4}{25}[/tex] = [tex]\frac{25}{25}[/tex] - [tex]\frac{4}{25}[/tex] = [tex]\frac{21}{25}[/tex] , then

cosΘ = [tex]\sqrt{\frac{21}{25} }[/tex] = [tex]\frac{\sqrt{21} }{\sqrt{25} }[/tex] = [tex]\frac{\sqrt{21} }{5}[/tex]

To find the weight of 4.3 cubic feet of water, we need to first find the number of gallons of water that 4.3 cubic feet holds and then multiply that by the weight of 1 gallon of water.

1 cubic foot holds 7.48 gallons of water, so 4.3 cubic feet holds 4.3 x 7.48 = 31.964 gallons.

1 gallon of water weighs 8.33 pounds, so 31.964 gallons of water weigh 31.964 x 8.33 = 265.9012 pounds.

Therefore, 4.3 cubic feet of water weigh 265.9012 pounds.

To find the weight in tons, we need to divide the weight in pounds by 2000:

265.9012 pounds ÷ 2000 = 0.13295 tons

So 4.3 cubic feet of water weigh 0.13295 tons.

Answer:

0.13314 tons.

Step-by-step explanation:

We can start the calculation by first converting the cubic feet of water to gallons and then converting the gallons to pounds.

Conversion from cubic feet to gallons:

4.3 cubic feet = 4.3 cubic feet * 7.48 gallons/cubic foot = 32.084 gallons

Conversion from gallons to pounds:

32.084 gallons = 32.084 gallons * 8.33 pounds/gallon = 266.279 pounds

Conversion from pounds to tons:

266.279 pounds = 266.279 pounds / 2000 pounds/ton = 0.13314 tons

So, 4.3 cubic feet of water weigh 266.279 pounds or 0.13314 tons.

Answer:

a = 5, b = 5√3

Step-by-step explanation:

Use sin law

sin A/a = sin C/c

sin 30/a = sin 90/10

sin 30/(sin90/10) = a

a = 5

sin B/b = sin C/c

sin 60/b = sin 90/10

sin 60/(sin90/10) = b

b = 5√3

How to determine this

Using product rule,

[tex]\frac{d}{dx}[/tex](u.v) = du/dx.v + dv/dx.u

where u = x-5

v = x+7

Using the rule,

d/dx = 1(3x + 7) + 3(x - 5)

d/dx = 3x +7 +3x - 15

d/dx = 6x - 8

Using the expanding, then differentiating,

d/dx = (x - 5)(3x + 7)

open bracket,

d/dx = 3x^2 + 7x - 15x - 35

Differentiating it,

There are approximately 205.33 gallons of water in the water cooler when it is completely full.

What is the volume of the cylinder?

The volume of a cylinder is given by the formula:

V = πr^2h

where V is the volume, r is the radius, and h is the height of the cylinder.

The volume of the cylindrical water cooler is:

V = πr^2h

where r is the radius and h is the height. Substituting the given values:

V = 3.14 x (3.5/2)^2 x 2

= 27.44 cubic feet

To convert cubic feet to gallons, we can multiply by 7.48 gallons/cubic foot:

V = 27.44 x 7.48

= 205.32 gallons

Rounding to the nearest hundredth, the answer is:

205.32 ≈ 205.33 gallons

Hence, there are approximately 205.33 gallons of water in the water cooler when it is completely full.

Answer:

$475

Step-by-step explanation:

Let's call the cost of the dryer x. That means the cost of the washer is x + $43. The combined cost of the two is $993, so we can write the equation:

x + (x + $43) = $993

Expanding the right side:

2x + $43 = $993

Subtracting $43 from both sides:

2x = $950

Dividing both sides by 2:

x = $475

So the cost of the dryer is $475.

From unit prices gotten, the price of one feet of annel fabric is cheaper than the price of one feet of fleece fabric.

The parameters are;

3 yards of annel fabric costs $12.60

5 feet of fleece fabric costs $8.75.

From conversion units;

1 yard =  3 feet

Thus;

3 yards = 3 * 3 = 9 ft

Thus;

Step-by-step explanation:

[tex]b = \bar y - m\bar x[/tex]An equation that models that population growth of the small town is y = 2,453.75x + 88,499.37 .

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

The given table is:

Year (x)                          0,              1,           2,              3

Population (y)            88,000,    90,640,  93,359,    96,160

We can use the least squares method to estimate the slope and y-intercept.

The formula for the slope (m) is:

[tex]m = \dfrac{\sum(x - \bar x)(y - \bar y)}{ \sum(x - \bar x)^2}[/tex]

The formula for the y-intercept (b) is:

[tex]b = \bar y -m \bar x[/tex]

Using the data from the table, we can calculate the mean of x and y:

[tex]\bar x[/tex] = (0 + 1 + 2 + 3) / 4

  = 1.5

[tex]\bar y[/tex] = (88,000 + 90,640 + 93,359 + 96,160) / 4

  = 92,180

Next, we can calculate the slope (m) and y-intercept (b):

m = (0 - 1.5)(88,000 - 92,180) + (1 - 1.5)(90,640 - 92,180) + (2 - 1.5)(93,359 - 92,180) + (3 - 1.5)(96,160 - 92,180)² / (0 - 1.5) + (1 - 1.5)² + (2 - 1.5)² + (3 - 1.5)²

= (-2.25)(-4,180) + (-0.5)(-1,540) + (0.5)(1,179) + (2.25)(4,980) / 2.25² + 0.5²+ 0.5² + 2.25²

= 2,453.75

b = 92,180 - (2,453.75 x 1.5)

  = 92,180 - 3,680.63

  = 88,499.37

So, the equation that models the growth of the population is:

y = 2,453.75x + 88,499.37

The total cost of the ingredient to make the cake and the comparison to the percentage discount to get the best deal indicates that we get;

A percentage is the representation of a proportion of an item per 100 of a set of items.

Quantity of flour = 5 lb

Unit cost for the flour = $2.74 per lb

Quantity of sugar = 2 1/2 lb

Unit cost of the sugar = $1.70 per lb

Quantity of butter = 2 lb

Unit cost of the butter = $7.49 per lb

Quantity of eggs required = 1/2 dozen

Cost of six eggs = $4.85

Miss Brown's total bill for the four items, C, is therefore;

C = 5 × 2.74 + (2 1/2) × 1.7 + 2 × 7.49 + 4.85 = 37.78

The discount available for purchases of $50 or more = 5% discount on the purchase

Lisa's current annual income is $76200, and her annual net income is 80% of that, or $60960. On a monthly basis, her net income is ...

  $60960/12 = $5080 . . . . . . Lisa's current net monthly income

If her income is reduced by 35%, the reduction is ...

  0.35 × $5080 = $1778

Then Lisa's part-time monthly net income will be ...

  $5080 -1778 = $3302 . . . . . Lisa's part-time monthly net income

The family net income will be reduced by the same amount:

  $13150 -1778 = $11372 . . . . . new family monthly net income
