Let d1 be the diameter of the moon and d2 and be the diameter of the earth.Let r1 be the radius of the moon and r2 be the radius of the earth.
![given \: d1 = \frac{1}{4}d2 \\ = > 2r1 = \frac{1}{4} ×2r2 \\ =>r1 = \frac{1}{4}×r2 \\ Now, \: ratio \: of \: \: their \: surface \: areas \: is: \\ = s1: s2 \\ = r {1}^{2}: r {2}^{2} \\ = {1}^{2 } : {4}^{2 } \\ =1:16](https://tex.z-dn.net/?f=given%20%5C%3A%20d1%20%3D%20%20%5Cfrac%7B1%7D%7B4%7Dd2%20%5C%5C%20%3D%20%3E%202r1%20%3D%20%20%5Cfrac%7B1%7D%7B4%7D%20%C3%972r2%20%20%5C%5C%20%20%3D%3Er1%20%3D%20%20%5Cfrac%7B1%7D%7B4%7D%C3%97r2%20%5C%5C%20Now%2C%20%20%5C%3A%20ratio%20%5C%3A%20%20of%20%5C%3A%20%20%5C%3A%20%20their%20%20%5C%3A%20surface%20%5C%3A%20%20areas%20%5C%3A%20%20is%3A%20%20%5C%5C%20%3D%20%20s1%3A%20s2%20%5C%5C%20%20%3D%20r%20%7B1%7D%5E%7B2%7D%3A%20r%20%7B2%7D%5E%7B2%7D%20%5C%5C%20%3D%20%7B1%7D%5E%7B2%20%7D%20%3A%20%7B4%7D%5E%7B2%20%7D%20%5C%5C%20%3D1%3A16)

7.25 hour is better because multiply by eleven and its 79.75 which is higher than the on on the table
This is from simple math knowledge of lines, segments and points. From the given data, pr and rs are line segments in the line ps. Thus, we add segments pr and rs together to solve for the line ps.
pr + rs = ps
4x - 2 + 3x - 5
(Add like terms) = 7x -7
(Further simplify) = 7(x-1)
Therefore, the final answer or expression of ps = 7(x-1).
Answer:
is it 2

Answer:
√69 is 8.30 and √72 is 8.48.
The one after N should be 8.50.
So really it should be N, not M, im sorry. Because M is 8.20
So its N
