8. Bob bought a pair of tennis shoes on sale for $72 at a sport's store. The original
price of the shoes was $90. What was the
percent of
decrease
?
PLEASE HELP ASAP

20%

Step-by-step explanation:

So, I would set this up as a proportion-

72          x

90        100

Cross multiply-

100 x 72 = 7200

Divide-

7200/90 = 80

Subtract-

100 - 80 = 20

So, it is a 20% decrease

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
