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!
Answer:
The percent increase is 10%
Step-by-step explanation:
Percentage increase = 
in this case we have;
((33-30)/30)*100%
(3/30)*100= 10%
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)
Answer:
1,-2
Step-by-step explanation:
You can also say the answer is C.
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.
