Adliyn mows 2 lawns first is 6 meters long and the second is 4 meters wide. The area of the second lawn is 6 times as big but has the same width of the first. What is the length of the second lawn

Answers

Answer:

The area of the first lawn is 64 = 24 square meters.

The area of the second lawn is 6 times bigger, so it is 246 = 144 square meters.

As the second lawn has the same width as the first one, 4 meters, we can calculate the length of the second lawn by dividing the area of the second lawn by its width.

So, the length of the second lawn is 144/4 = 36 meters.

Lee has made a nonrefundable deposit of the first month’s rent (equal to $900) on a
apartment lease to 6 months. The same day later Lee finds a different apartment that
he likes just as well, but its monthly rent is cheaper and negotiable. Assume a nominal
rate interest rate of 8% convertible monthly. The rent will be paid monthly and at the
beginning of each month.

(i) Write down the cash flow and compute the present value (to 2 decimal numbers)
of 6 months if Lee rents the first apartment ($900).
(ii) Find the range of the rent (to 2 decimal numbers) of the cheaper apartment such
that Lee would switch to rent the new apartment.

Answers

Answer:

(i) To calculate the present value of 6 months of rent for the first apartment, we can use the formula PV = FV / (1 + r)^n, where PV is the present value, FV is the future value (6 months of rent, or $900 x 6 = $5400), r is the interest rate (8% converted to a monthly rate, or 0.08/12 = 0.0067), and n is the number of periods (6 months). So, PV = $5400 / (1 + 0.0067)^6 = $4911.46

(ii) To find the range of rent for the new apartment such that Lee would switch, we need to find the monthly rent that would result in a present value equal to or greater than $4911.46. Using the same formula, we can solve for the monthly rent (R) by setting PV equal to $4911.46 and n equal to 6. So, $4911.46 = R*(1+0.0067)^6. Solving for R, we get that the monthly rent must be between $732.32 and $766.58 in order to be more favorable than the first apartment.

The weight of a sphere is proportional to the radius cubed. If a sphere of diameter 1 cm has a mass of 2 grams what diameter sphere has a mass of 54 grams?

Answers

Let's call the radius of the first sphere "r1". Then, its diameter is 2 * r1 = 1 cm, so r1 = 0.5 cm.
The mass of the sphere is proportional to the radius cubed, so we can write:

m = k * r1^3

where k is the constant of proportionality. We know that m = 2 g and r1 = 0.5 cm, so we can solve for k:

k = 2 / (0.5)^3 = 32 g/cm^3

Now we can use the constant k to find the mass of a sphere of radius "r2":

m = k * r2^3

We want to find the radius of a sphere with a mass of 54 g, so we can substitute m = 54 g:

54 = 32 * r2^3

Finally, we can solve for r2:

r2 = (54 / 32)^(1/3) cm

So, the diameter of the sphere with a mass of 54 g is 2 * r2 cm

A 10 kg ball moves at a speed of 15m/s. The ball collides with a wall causing it to rebound in the opposite direction at a speed of 23 m/s.
Calculate the impulse on the ball?

Answers

Answer:

The impulse on an object is equal to the change in momentum of the object. In this case, the ball's initial momentum is 10 kg * 15 m/s = 150 kg m/s. After the collision, the ball's final momentum is -10 kg * 23 m/s = -230 kg m/s.

The change in momentum of the ball is: -230 kg m/s - 150 kg m/s = -80 kg m/s.

So, the impulse on the ball is -80 kg m/s.

(b) Radius of needed for the cone to contain 14.5 cubic inches per serving is about 1.422 inches

Rotation of a quarter circle to form an hemisphere, by integration is presented as follows;

[tex]\int\limits^1_0 \pi \times ({\sqrt{1-x^2} })^2 \, dx = \frac{2}{3} \cdot \pi[/tex]

The volume of the cone carrying the hemisphere = (1/3)×π×1²×4 = (4/3)·π

The volume of the ice cream = The volume of the cone + The volume of the hemisphere

Therefore;

Volume of the ice cream = (2/3)·π + (4/3)·π = (6/3)·π = 2·π  ≈ 6.3

The volume of the ice cream ≈ 6.3 cubic inches

(b) Volume of ice cream contained in the new ice cream cone, V = 14.5 cubic inches

The formula for the volume of the ice cream, V = (2/3)·π·r³ + (4/3)·π·r²

Therefore;

V = (2/3)·π·r³ + (4/3)·π·r² (substitution property)

V = (2/3)·π·r³ + (4/3)·π·r²

14.5 = (2/3)·π·r³ + (4/3)·π·r²

89.0 mL of a liquid is massed in a graduated cylinder. The total mass is 437.2 g. The empty graduated cylinder has a mass of 277.0 g. What is the density of the liquid?

Answers

To find the density of the liquid, we need to calculate the mass of the liquid and divide it by its volume.

Steps:

Determine the mass of the liquid by subtracting the mass of the empty graduated cylinder from the total mass:
437.2 g - 277.0 g = 160.2 g

Convert the volume of the liquid from mL to L:
89.0 mL * 1 L/1000 mL = 0.089 L

Calculate the density by dividing the mass of the liquid by its volume:
160.2 g / 0.089 L = 1,801.12 g/L
So, the density of the liquid is 1,801.12 g/L.

Paul's Pizza sells pizza by the slice for lunch. An employee recorded how many slices of each type of pizza were sold today. pepperoni 44 cheese 15 supreme 29 Considering this data, how many of the first 76 slices sold during lunch tomorrow should you expect to be slices of pepperoni pizza?

Answers

Answer:

To find out how many of the first 76 slices sold during lunch tomorrow should be pepperoni pizza, we can use the information provided about the proportion of pepperoni pizza slices sold today. We can use the following formula to calculate the expected proportion:

(number of pepperoni slices / total number of slices) * 100

Plugging in the numbers we have:

(44 / (44 + 15 + 29)) * 100 = 44 / 88 * 100 = 50%.

So we can expect 50% of the first 76 slices sold during lunch tomorrow to be pepperoni pizza slices, which is equivalent to:

76 slices * 50% = 38 slices

Therefore, we expect 38 of the first 76 slices sold during lunch tomorrow should be slices of pepperoni pizza.

We have the parameters;

m/MKL = 61 + 9xm/MNO = 2x + 75

Note that the midpoint of the triangle is expressed as;

m/MKL = m/MNO

Now, substitute the values, we get;

collect like terms

9x - 2x = 75 - 61

add or subtract the like terms

7x = 14

Now, divide both sides by the coefficient of x, we get;

Divide the values

x = 2

Substitute the value into the expression

Answer:

Greg borrowed $20,000.

Step-by-step explanation:

To calculate the principal (the amount borrowed), we can use the formula for simple interest:

I = Prt

where I is the interest, P is the principal, r is the annual interest rate, and t is the time in years.

Given that:

I = 1400

What is tape diagram?

A diagram that resembles a piece of tape that is used to show how numbers relate to one another. Also known as length model, fraction strip, bar model, and strip diagrams. to use whole numbers, fractions, and ratios to answer problems that include the four operations. Students can improve their problem-solving abilities and algebraic reasoning with the use of tape diagrams.

A visual tool known as a tape diagram represents the components of a ratio using equal-sized boxes. The reason it is named a tape diagram is because it resembles the lengthy strips of sticky tape used to bind documents or wrap gifts.

Given the following diagram and the fact that HJK=138 find the m LJK

Answers

Answer:

<LJK = 69 degrees

Step-by-step explanation:

Triangle HKL and LJK are congruent, therefore their angles will be as well. Divide HJK by 2; 138 / 2 = 69

The table below represents a geometric sequence. Determine the recursive function that defines the sequence.

Answers

Answer:

C

Step-by-step explanation:

How do we get from 4 to 20? Multiply 4 * 5 = 20.

How do we get from 20 to 100? Multiply 20 * 100.

Thus the answer is C where you multiply 5 by the previous function output.

I saw this pattern from experience, however you could also solve another way:

Simply plug in to the given functions in each answer choice.

For example, A:

f(1) = 4

f(n) = 16 * f(n - 1), for n >= 2

Now test values of n and check if they match the table.

f(1) = 4. This matches the table

f(2) = 16 * f(2 - 1) = 16 * f(1) = 16 * 4 = 64. This does not match the table.

You continue this process with the rest of the answer choices until you find a function, f(n), that gives the correct output of the table.
