During exercise, the recommended maximum heart rate in beats per minute is modeled by the formula M=176-0.8A, where M is the maximum heart rate and A is the person’s age. Approximately, at what age would you have a recommended heart rate in beats per minute of 125?
A.52 years
B.64 years
C.67 years<---
D.70 years

So if m= max heart rate, which you know is 125. Then write the equation as. 125=176-0.8A. Now solve for A to get the persons age. You will need to round to get the answer.

I did 175.2 multiplied by 0.7134 then I rounded to get 125. So I don't get how to get the answer!!!

It doesn't make sense!!!
Answered by Ms. Sue
125 = 176- 0.8A

125 - 176 = - 0.8A

-51 / -0.8 = A

63.75 = A
Answered by Elle
To start with, you're not supposed to multiplying anything. M= 176-0.8A. M+ 0.8A=176. We know what m is, so the equation becomes 125 + 0.8A = 176. We rearrange the equation to be 0.8A= 176-125. Now to get A by itself, we divide both sides by 0.8 so then A= (176-125)/0.8

135** sorry
Answered by soneillon
solved it myself. for 2021 answer is 51.
176- (0.8 x 51)= 135.2

Lisa takes a loan of $10,500 at a 9% simple interest rate for 7 years.
How much interest will she pay after 3 years?
How much interest will she pay in total for the loan?

M = 176 - 0.8A

Substituting M with 135:

135 = 176 - 0.8A

0.8A = 176 - 135

0.8A = 41

A = 41/0.8

A = 51.25

Therefore, the recommended heart rate of 135 beats per minute would be approximately for a 51-year-old person.

M = 300J/P

Multiplying both sides by P, we get:

MP = 300J

Dividing both sides by 300, we have:

J = MP/300

Therefore, the solution for J is J = MP/300.

The common difference between adjacent terms in column a is 1. So, 10 should be the next term in column a.

To find the missing value in column b, we note that the common difference of the terms in column b is equal to (the value of the 2nd term - the value of the 1st term) which is equal to (the value of the 3rd term - the value of the 2nd term) which is 0.8.

So, the missing value in column b can be found by adding the common difference to the previous term, which is 6.2 in this case:

5.4 + 0.8 = 6.2

Therefore, the missing value in column b is 6.2.

First, we can use the formula for simple interest to calculate how much interest Lisa will pay in total for the loan:

I = Prt

Where I is the interest, P is the principal (the amount of the loan), r is the interest rate as a decimal, and t is the time in years.

So for Lisa's loan:

I = (10,500)(0.09)(7)

I = $6,615

Therefore, she will pay a total interest of $6,615.

To find out how much interest she will pay after 3 years, we can use the same formula but with t = 3:

I = (10,500)(0.09)(3)

I = $2,835

Therefore, she will pay $2,835 in interest after 3 years.
