D, because the sum is no more than 28 so it could be equal or less than.
Answer:
1. A. AC=3IN
2. D AND C
Step-by-step explanation:
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
Answer:
18/100 or 9/50
Step-by-step explanation:
0.18 = 0.18/1
times 100 then 18/100
divided by 2 then 9/50
Answer:
0.25 I think
