Reagan surveyed a number of her classmates about what time they usually go to bed. Of the fifteen classmates she asked, nine sai
sleet_krkn [62]
9 out of Reagan's 15 classmates go to bed at 10 p.m.

As a fraction, this would be 9/15.

To convert a fraction to a decimal, you just divide the numerator by the denominator.

Thus, 9 ÷ 15 = 0.6

To turn a decimal into a percentage, you multiply the decimal by 100, and then add a percentage sign.

0.6 * 100 = 60%

Therefore, 60% of Reagan's classmates go to bed at 10 p.m.

Hope this helps!

V=pie*r^2*h solve for r
ankoles [38]

Answer:

r = √(V/πh)

Step-by-step explanation:

V=π*r^2*h solve for r

divide both sides by πh

V/πh = π*r^2*h/πh

Simplify

V/πh = r^2

so r = √(V/πh)

What is the square of 8 step by step​
Marysya12 [62]

Step-by-step explanation:

Here is a helpful method I taught my students in my mini lesson...

For you to remember, 22= 4, and 32= 9. Hence the answer to the root of 8 lies between the numbers 2 and 3. However, since the square of 3 equals to 9 which is larger than 8, the root 8 value lies in between the number 2.8 and 2.9.
