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

Answer: she has 195 miles more to cover
Step-by-step explanation:
A salesperson has to drive 500 miles.
For the first three hours she drove at 65 miles/hour.
Distance = speed × time.
This means that distance covered in the first 3 hours is
65 ×3 = 195 miles
For the next two hours she drove at 55 miles per hour.
This means that distance covered in the next two hours is
55 × 2 = 110 miles
The total distance that the salesperson has to cover is 500 miles
Distance already covered is
195 + 110 = 305 miles
Distance remaining will be total distance - distance already covered. It becomes
500 - 305 = 195 miles
Answer:
Initially:
Cam has X stickers.
Dan has 2x.
Dan gives Cam 15 stickers:
Cam has x + 15 stickers.
Dan has 2x - 15 stickers.
2x - 15 = (x + 15) + 22.
X = 52 stickers.
x + 15 = 52 + 15 = 67 stickers.
2x - 15 = 2*52 - 15 = 89 stickers.
