Question

you use a garden hose to fill a wading pool. if the water rises 11 centimeters every 5 minutes and you record the data point of (10,y), what is the value of y? Use slope to justify your answer.

Answer 1

Answer:

22 centimeters.

Explanation:

If the water rises 11 centimeters every 5 minutes, the slope is equal to:

$\text{Slope}=\frac{Rise}{Time}=\frac{11\text{ cm}}{5\text{ min}}=2.2\text{ cm per min}$

Then, the data point (10, y) is the height of the water y after 10 minutes. So, we can calculate the value of y as:

$y=\text{Slope}\times\text{ time = 2.2 }\times\text{ 10 = 22 centimeters.}$

Therefore, the value of y is 22 centimeters.
