Answer 2

Megan's resting heart rate (RHR) is 90 beats per minute. She know's that a lower rate of RHR is a sign of a healthier cardiovascular system. Her goal is to have a RHR of 72 beats per minute. Megan would need to improve her present resting heart rate by what percentage to achieve her goal?

10%
15%
20%
25%

Answer 3

Owe. I really don't know this one. Try google! :3

Answer 4

well...all you need to do here is take your original number: 90
and multiply it by the percentage...
such as...lets try 20%
90 x .20 = 18
90 - 18 = 72
aka your answer :)

Answer 5

Thank's Undead..

Answer 6

any time miss nieces.

Answer 7

Instead of guessing which percent to use, use a variable like x.

90x = 72
x = 72/90
x = 0.8

That means that 72 is 80% of 90 and a 20% reduction

Answer 8

@cleats so 20%

Answer 9

100-80=20, yeah
