Doing exercise the recommended MaXimum heart rate and beats per minute is Modeled by the formula M= 176-0.8 a WhereM is the maximum heart rate Ans a is the persons age approximately at what age would you recommend that Heart beats per minute of 135
WHATS THE ANSWER!!!!!1!! PLEASE HELP
135 = 176 - .8a
Subtract 176 from both sides
divide by -.8 which will give you a positive answer which is the age.
Can someone help with the test?
if im correct the answer is 51.25 which is just 51
To find the approximate age at which the heart beats per minute (BPM) is 135, you can rearrange the formula to solve for age (a):
M = 176 - 0.8a
Given that M (maximum heart rate) is equal to 135, substitute this value into the equation:
135 = 176 - 0.8a
Next, isolate the variable a:
0.8a = 176 - 135
0.8a = 41
Divide both sides by 0.8:
a = 41 ÷ 0.8
a = 51.25
Therefore, at approximately 51.25 years old, the recommended heart beats per minute would be 135.
