5^-3 is 1/125
The negative in the exponent makes it so there is a 1 over the problem if there was no negative. When you have a negative in the exponent, the answer will be the reciprocal (opposite) of the question with no negative.
For example,
9^2 = 81
9^-2 = 1/81
The mean = sum of all the measurements / number of measurements (n)
= (5 + 3 + 3 + 8 + 8) / 5
= 27 / 5
= 5.4 Answer
Answer:
<em>A≈606.32</em>
Step-by-step explanation:
you need to use this equation: A=πr(r+h^2+r^2) to figure it out...
just plug your length, height, and radius in, and u have ur answer!!
ur answer shud be <em>A≈606.32</em>

Hope this helps!!
The solution is as follows:
Set up the proportion:
70% - 98
90% - x
70% / 90% = 98 / x
7 / 9 = 98 /x
(7 / 9) x = 98
x = 98 x 9/7
x = 14 x 9
x = 126
The answer is <span>D. 126.
I hope my answer has come to your help. God bless and have a nice day ahead!</span>
