Five out of seven teens said they do homework every night. What is a reasonable prediction for the number of teens out of 980 wh
alexdok [17]

Answer:

700 teens

Step-by-step explanation:

If five out of 7 teens do homework every night

There are 980 teens

How many out of 980 teens would do homework every night?

Firstly divide 980 teens by 7

Which is 980/7=140

Next is,

Out of 7 teens, there are 5 who do homework every night

So, multiply 140 by 5

140×5=700 teens

This means, the reasonable prediction of teens who do homework every night out of 980 is 700 teens

Find the difference in the volume and total area of a cylinder with both a radius and height of1 r-1, h-1
Diano4ka-milaya [45]

Although I am not clear as to whether the radius is r—1 or otherwise, but if i work with the values i see then:

Volume — T. S. A.

= πr²h — (2πr²+2πrh)

So after the simplification, I substitute the values given,

r= r—1 and h=h—1

And the answer is...

π(r—1)(rh—3r—3h+5)!
