Answer:
Yes because 5^2 + 12^2 = 13^2
Step-by-step explanation:
We can check using the Pythagorean theorem
a^2 + b^2 = c^2
5^2 + 12^2 = 13^2
25+ 144= 169
169 = 169
Number of ppl that said they played hockey / total ppl =
495/2286 (simple division to turn to a decimal)
0.2165 (now multiply the decimal by 100 to get ur percent)
0.2165 * 100 = 21.65%...or if it needs to be rounded, it is 22%
There are a couple of equations u can use
x = original price
15% off the original price of the purchase :
x - 0.15x
OR
if u get 15% off, then u are paying for 85%
0.85x
