256.74 should be the answer just use a calculator
I think they mean apples, coins or something along those lines.
The coin was thrown 500 times.
Answer:
<u>see explanation </u>
<u></u>
Step-by-step explanation:
In math, when a number is squared, it means it has been multiplied by itself. For instance, two squared equals two times two, or four.
In this same case x^2---> x * x
x times x ---> x^2
The side lengths of the mirrors are 1.5 ft and 2.5 ft respectively.
<u><em>Explanation</em></u>
Given that, the area of smaller mirror is 2.25 ft² and the area of larger mirror is 6.25 ft²
<u>Formula for the area of a square</u> :
, where
is the side of the square.
Lets assume, the side length of smaller mirror is
ft and the side length of larger mirror is
ft.
So....
![x^2= 2.25\\ \\ x= \sqrt{2.25}=1.5](https://tex.z-dn.net/?f=x%5E2%3D%202.25%5C%5C%20%5C%5C%20x%3D%20%5Csqrt%7B2.25%7D%3D1.5)
and
![y^2= 6.25\\ \\ y= \sqrt{6.25}=2.5](https://tex.z-dn.net/?f=y%5E2%3D%206.25%5C%5C%20%5C%5C%20y%3D%20%5Csqrt%7B6.25%7D%3D2.5)
Thus, the side length of smaller mirror is 1.5 ft and side length of larger mirror is 2.5 ft.
