Answer:
Your answer is about 12.48
Step-by-step explanation:
h = 3(V/pi*r²)
h = 3(640.23/pi*7²)
h = 3(640.23/153.93804)
h = 3(4.157516881)
h = 12.47703

<u>Solving the problem</u>
Stacy is correct
Answer:
x=7.31
Step-by-step explanation:
There are two x's, so they represent the equation 2x=14.62. If we solve for x, we have to divide each side by 2:
2x/2=14.62/2.
If we divide, we get x=7.31
We are trying to find the average speed of the plane, which is mph, or 
. Using proportions, we can find the average speed of the plane in mph:
- Use the information from the problem to create a proportion. Remember that we are looking for mph, so we will call that
.
- Multiply the entire equation by
- Divide both sides of the equation by
to clear both sides of the mile unit
The average speed of the plane is 300 mph.
