A ball is dropped from 64 feet assume that on each bounce it rebounds one half of the distance of the previous bounce after how many bounces will the ball be at 0.125 feet at this point what is the total distance the ball traveled in inches

Answers

the ball bounced a total of 9 times     to find that answer you divide 64 by 2  and that (32 feet ) is one bounce then repeat till you get .125

so if you add each of the bounce heights you get 127.875  the total distance

2+d=2-3(d-5)-2 Pls show work

Answers

2 + d = 2 - 3(d- 5) - 2

First, cancel 2 on both sides. / Your problem should look like: d = -3(d - 5) - 2
Second, expand. / Your problem should look like: d = -3d + 15 - 2
Third, simplify -3d + 15 - 2 to get -3d + 13. / Your problem should look like: d = -3d + 13
Fourth, add 3d to both sides. / Your problem should look like: d + 3d = 13
Fifth, add d + 3d to get 4d. / Your problem should look like: 4d = 13
Sixth, divide both sides by 4. / Your problem should look like: d =  (13)/(4)

Answer as fraction: d =  (13)/(4)
Answer as decimal: d = 3.25


2+d=2−3(d−5)−2

2+d=2+(−3)(d)+(−3)(−5)+−2(Distribute)

2+d=2+−3d+15+−2

d+2=(−3d)+(2+15+−2)(Combine Like Terms)

d+2=−3d+15

Add 3d to both sides.

d+2+3d=−3d+15+3d

4d+2=15

 Subtract 2 from both sides.

4d+2−2=15−2

4d=13

Divide both sides by 4.

4d/4=13/4

d=13/4

The answer is C. If you use the pythagorean theorem,a^2+b^2=c^2, and connect the two points together at a right angle and pug in the lengths of the two lines to the equation then the answer should be C.

What is 20% of 120 and how do u get the answer

Answers

20% of 120 is 24.

To find this answer, you need to use the percentage formula (is over of equals the percentage over 100, is/of = p/100).

Plug in the known numbers. You know you need 20%, so plug 20 into the percentage place.

is/of = 20/100

You know the "of," which is 120, so plug that in.

is/120 = 20/100

You don't know the "is," so to find it you need to multiply cross multiply 120 by 20. Then you need to divide your answer by 100 to find your missing value (is).

120 * 20 = 2,400
2,400 / 100 = 24
Multiply 120 by .2 to get 24
