1/4=0.25 miles
5/0.25=20 laps
José has to run 20 laps to run 5 miles.
If the ball hit the ground it means that its height is equal to 0. In order to find the time after the ball <span>will hit the ground, we need to find the solution of the equation h(x)=0 which is different to 0.
-4.9x^2+21.3x=0
x(-4.9x+21.3)=0
-4.9x+21.3=0
x=21.3/4.9 = 4.3469 seconds</span>
11. 375x0.1425 = 53.475 (53.44 to 2 d.p.)
12. 116 / (9+7) = $7.25
Total payment / Hours spent working = Money per hour

Step-by-step explanation:
I can't see the shape
The formula to calculate the volume of a cone is:
![V= \frac{1}{3} \pi (radius)^2h](https://tex.z-dn.net/?f=V%3D%20%5Cfrac%7B1%7D%7B3%7D%20%20%5Cpi%20%28radius%29%5E2h)
So, replace radius = 3in and h = 8 in.
The result is: [1/3] π (3in)^2 (8in) = [1/3]π(9)(8) in^3 = 24 π in^3
Answer: option b. 24 π in^3
