Use Slader.com, Find the math book and look up the page. It will show you the answer and how to get it.
15/x = 20/100
15*100 = 20*x
1500 = 20x
1500/20 = 20x/20
75 = x
15/75 = 20/100

Answer:
maximum height =7.347m
Step-by-step explanation:
maximum height = (U²sin²θ)/2g
where θ = 90° as the ball is thrown straight up.
sin90°=1 , so our formula reduces to;
H= U²/2g
U=12m/s , g=9.8m/s²
H= 12²/(2*9.8)
H=7.347m
