The distance travelled in (m) by a ball dropped from a height are 128/9,32/3,8,6,...

Allushta [10]

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

A worker submits the following data on a timesheet: Week 1 — Total hours: 42 (including 4 hrs sick leave, 6 hrs travel) Week 2 —

Assoli18 [71]

Answer:

12.5%

Step-by-step explanation:

In order to find the percentage the worker spent traveling, we can make us of the following ratio:

$\frac{number}{ammount}=\frac{percent}{100}$

where number is how many hours he spent traveling, ammount is the total ammount of hours he reported and percent is the percentage we want to find. So we can solve the ratio for the percent, so we get:

$percent=\frac{number}{ammount}*100%$

now, we need to find the total amount of hours he spent traveling, this is gotten by adding the provided data:

6hrs+5hrs=11hrs

next we need to find the total amount of hours reported:

42hrs+46hrs=88hrs

so now we can substitute the data the problem provided us with:

$percent=\frac{11}{88}*100%$

which yields:

percent=12.5%

A sphere has radius of 42 m. If the radius is divided by 6, what is the effect on the surface area? HELP ASAP!

Tatiana [17]

A sphere with radius $r$ has surface area $4\pi r^2$ . Divide the radius by 6 and you get a surface area of $4\pi\left(\dfrac r6\right)^2=\dfrac4{36}\pi r^2$ , so that the final surface area is divided by 36.
