Let us say
The Height from which the ball was first dropped as H0 = 248 feet
The Height reached by the ball after second bounce is H1
The Height reached by the ball after second bounce is H2 = 62 feet
Given , Height the ball reaches after bounce is a fraction of the height the ball reached in the previous bounce
The Height reached by the ball after second bounce = H2 = X of H1
==> 62 = X * H1 ...................Equation 1
The Height reached by the ball after first bounce = H1 = X of H0
==> H1 = X * 248 ...................Equation 2
Substituting value of H1 from Equation 2 to Equation 1
62 = X * H1 = X * X * 248
X^2 = 62/248 = 31/124 = 1/4
X = 1/2
Answer is A. 1/2

First, you need to know what the lines | | mean.
| | around a number means the absolute value.
The inequality is |y|>6
This means that the absolute value of y is greater than 6.
Now, we need to find the absolute value of the choices.
A. y=-7
|-7| is 7
B. y=-1
|-1| is 1
C. y=3
|3| is 3
D. y=9
|9| is 9
Now, we find which of the absolute values work in the inequality.
7 is greater than 6, so that works
1 is less than 6, so it doesn't work.
3 is also less than 6, so that too doesn't work.
9 is greater than 6, so the one will work.
Therefore, choices A and D satisfy the inequality of |y|>6, because |-7|>6, and |9|>6.
The answer is 18 inches to 4 feet Hopes this helps
