If you would like to know 52.5% of what number is 25.83, you can calculate this using the following steps:
52.5% of what number is 25.83
52.5% * x = 25.83
52.5/100 * x = 25.83 /*100/52.5
x = 25.83 * 100 / 52.5
x = 49.2
Result: 52.5% of 49.2 is 25.83.
Number 1 is A. Flipping a coins gives you heads or tails. There are four colors on the spinner. That would give you:
H - R
H - B
H - G
H - Y
T - R
T - B
T - G
T - Y
For number two I'm assuming you mean what the probabilities are that you select an eraser that isn't pink.
There are 14 erasers. The probability of picking an eraser is 14/14. You need to subtract the probability of picking a pink eraser to find the probability of not getting a pink eraser.14/14 - 4/14 is 10/14. That can be simplified to 5/7 which would be C.

Step-by-step explanation:
You can check to see if the numbers satisfy the Pythagorean theorem.
9² +12² ?= 15²
81 + 144 = 225 . . . . yes these segments form a right triangle
_____
You know that segments of lengths 3, 4, 5 form a right triangle. This is the first "Pythagorean triple" that most folks run across. The segments given here are all 3 times those numbers, so will also form a right triangle.
