Answer:
B
Step-by-step explanation:
617/500 = 1234/1000
Therefore option B is the answer.
12/3 = x/8
Cross multiply
3x = 96
Eliminate
3x/3 = 96/3
x = 32
Answer: it will trave 56.89 meters before coming to rest.
Step-by-step explanation:
This is a geometric progression since the distance travelled (height) by the ball is reducing by a constant ratio, r. Since the number of times that the ball will bounce is infinite, then we would apply the formula for determining the sum of the terms in a geometric progression to infinity which is expressed as
S = a/(1 - r)
where
S = sum of the distance travelled by the ball
a = initial distance or height of the ball
r = common ratio
From the information given,
a = 128/9
r = (32/3)/(128/9) = 0.75
Therefore,
S = (128/9)/(1 - 0.75) = 56.89 meters
12 months in a yr
57,000 / 12 = 4750 per month
