There are 5^5 students on the school and 5^2 students per class.
So, think:
1 class ----------- 5^2 students
x classes ---------- 5^5 students
Multiply:
1 . 5^5 = x . 5^2
So,
5^5 = x.5^2
x = 
x = 
x = 
x = 125
There are 125 classes.
The answer to this question is:
9x+8/3x^2
Well here is how you do it. you take 84 and estimate the ones place and do the same with 18. since 18 has a big number above 5 or more we raise the score. not to 19, but 20. The 4 in 84 is lower so it stays the sames. we don't keep it as 84 we change the number by taking out 4 and placing a zero. Now all we need to do is do the math. 80 - 20 = 60.

Answer:
2
Step-by-step explanation:
The distance between foci is the root of the difference of the squares of the axes lengths:
d = √(10² -8²) = √36 = 6
Then the radius of the circle is half the difference between this and the length of the major axis:
r = (10 -6)/2 = 4/2
r = 2
