Derek wants to determine the height of the top of the backboard on the basketball goal at the playground. He places a standard 1
s344n2d4d5 [400]

Answer:

10.2 feet.

Step-by-step explanation:

We have been given that Derek places  a standard 12-inch ruler next to the goal post and measures the shadow of the ruler and the backboard. If the ruler has a shadow of 10 inches. We are asked t find the height of the backboard, if the backboard has a shadow of 8.5 feet.

We will use proportions to solve our given problem as ratio between sides ruler will be equal to ratio of sides of background.

\frac{\text{Actual height of ruler}}{\text{Shadow of ruler}}=\frac{\text{Actual height of backboard}}{\text{Shadow of backboard}}

\frac{12}{10}=\frac{\text{Actual height of backboard}}{8.5}

\frac{12}{10}*8.5=\frac{\text{Actual height of backboard}}{8.5}*8.5

1.2*8.5=\text{Actual height of backboard}

10.2=\text{Actual height of backboard}

Therefore, the actual height of the back-board is 10.2 feet.

Person A is breathing five times as fast as person B. Compare the graphs of the breathing of the two people over time.
hammer [34]

Answer:

A

Step-by-step explanation:

Focus on what the question is telling you, as it's given to you in the question. It's saying five times, which means "×5" the number of person B, so it'll always be 5 times quicker, since they're breathing more times in a certain period of time than person B.

Hopefully this helped!
