Answer:
Thank you lol. I am so bored right now.
Step-by-step explanation:
it’s basically just any number that can be multiplied with another to get a new expression
Using the Pythagorean Theorem, you should get 45 [9 + 36]. Then, take the square root of 45 and simplify it to 3√5.
1. Total area of water = 352,000,000 + 9 * 10^6
= 352,000,000 + 9,000,000 = 361,000,000 = 3.61 * 10^8
Fraction of the surface covered by water = 3.61 * 10^8 / 5.1 * 10^8
= 3.61 / 5.1 = 0.707843 = 70.78 % to nearest hundredth of a percent.
