nikdorinn [45]

Answer:

C) 60.

Step-by-step explanation:

Okay, I do math a little bit different than other kids... No worries though, its still correct.


First, find out how many times five can be put into a hundred. You should have gotten 20.


Now, we can use the twenty we got. Multiply 20 by the ratio of the boys. So 20 * 3 = 60.

Girls would be

20 * 2 = 40.


Those two numbers add up to a hundred so its all good. ^-^

Which set of lengths are not the side lengths of a right triangle? (A-28, 45, 53) (B-13, 84, 85) (C-36, 77, 85) (D-16, 61, 65) [
nikklg [1K]
Side lengths 16, 61, and 65 are not part of a right triangle.

A right triangle's sides should follow this formula, C being the largest number:

a^{2} + b ^{2} = c^{2}

16^{2} = 256

61^{2} = 3721

65^{2} = 4225

256 + 3721 = 3977

3977  \neq 4225
