Determine the unit rate of the following.<br> 240 hours of homework in 8 weeks.
astra-53 [7]

Answer: 30\ \frac{hours}{week}

Step-by-step explanation:

In order to solve this exercise it is important to remember that a "Rate" is defined as a ratio that compares two different but related quantities.

Then, "Unit rate" tell us how many units of the first  quantity corresponds to one unit of the second quantity. Therefore, the second quantity is equal to 1.

According to the information given in the exercise, you know that the number of hours of homework in 8 weeks is 240 hours.

Then, in order to determine the Unit rate (the number of hours per week), you need to divide 240 hours by 8 weeks.

Through the procedure explained above, you get the that the number of hours per week is the following:

unit\ rate=\frac{240\ hours}{8\ weeks}\\\\unit\ rate=30\ \frac{hours}{week}

(Notice that it is 30\ hours\ per\ week)

In the last 20 years, an initial population of 24 pumas in a state park grew by about 12% per year. How many pumas were in the p
-BARSIC- [3]

Answer:

165 pumas

Step-by-step explanation:

Using the formula given:

n = a(1 + r)^t

where n = number of pumas after a specific number of years

a = initial number of pumas = 24

r = rate = 12% = 0.12

t = number of years = 17

We obtain the number of pumas after 17 years to be:

n = 24 *(1 + 0.12)^{17}\\\\\\n = 24*(1.12)^{17}\\\\\\n = 24 * 6.866

n = 164.78 ≅ 165 pumas

After 17 years, the number of pumas in the park was 165.
