Answer:
15
Step-by-step explanation:
8² + 15² = c²
To find : Value of c
8² = 8 x 8 = 64
15² = 15 x 15 = 225
c² = 225
225 = 15 x 15 = 15²
So,
c² = 15²
c = 15
Answer: The set of integers is closed for addition, subtraction, and multiplication but not for division.
The correct and best answer would be letter B. To find the percent of a discount, you have to find or solve for the percent of increase from the new price to the original price.

Answer:
17/72
Step-by-step explanation:
Let's make this equation easier to read.
.5/36 + 16(1/72)
Start by remembering PEMDAS
Parentheses
Exponents
Multiply
Divide
Add
Subtract
This is the order in which you will solve the problem. So multiplication first, then division, and finally addition.
Multiply 16 and 1/72
16/1 x 1/72 multiply across to get 16/72 which can be reduced to 2/9.
Divide .5 (or 1/2) by 36. To do this, multiply by the reciprocal of 36
1/2 x 1/36 = 1/72
Your equation is now
2/9 + 1/72
Your common denominator is 72, so multiply top and bottom of 2/9 by 8.
16/72 + 1/72 = 17/72
1$ = 100 cents, 1 hour = 60 minutes
$3.00/hour = (3*100) cents / (1*60)minutes
= 300 cents/60 minutes
= 5 cents/minute
Option b.
