Answer:

28.75 m

Step-by-step explanation:

a) First Fall  d=10 m ( first Hit)

b) Second fall

    height = 5 m

    height lost = 5 m (second hit)

Total = 10 m

c) Third Fall

Height = 2.50 m

height lost = 2.50 m (third hit)

Total distance = 5 m

d) forth Fall

Height = 1.25 m

Height lost = 1.25 m (forth hit)

Total distance = 2.50 m

e) fifth Fall

Height = 0.625 m

Height Lost = 0.625 m (fifth hit)

Total Distance = 10+5*2+2.50*2+1.25*2+0.625*2

=10+10+5+2.50+1.25

=20+7.50+1.25

=27.50+1.25

=28.75 m

Answer:

By the fifth bounce, it would reach 31.25 centimeters

Step-by-step explanation:

10/2=5

5/2=2.5

2.5/2=1.25

1.25/2=0.625

0.625/2=0.3125

0.3125 meters multiplied by 100(to get centimeters) = 31.25 centimeters

I hope this was helpful <3

777dan777 [17]

Answer:

6 times

Step-by-step explanation:

Let the number of times you visit the pool = x

At a local swim club you can purchase an annual membership for 24 dollars which will allow you 1 dollar admission to the pool all summer.

= $24 + $1× x

= 24 + x

If you do not purchase the membership the pool admission is 5 dollars.

= 5 × x

= 5x

Hence:

24 + x = 5x

Collect like terms

24 = 5x - x

4x = 24

x = 24/4

x = 6 times

The number of times you must visit the pool with a membership that would equal the cost of paying full price is 6 times.
