Question 255590: When getting into shape by exercising, the subject’s maximum recommended number
of heartbeats per minute (h) can be determined by subtracting the subject’s age from 220, and then taking 75% of that value. This relation is expressed by which of the following formulas?
A. h = .75(220 – a)
B. h = .75(220) – a
C. h = 220 – .75a
D. .75h = 220 – a
E. 220 = .75(h – a)
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
h = maximum number of heartbeats.
a = age.
h = .75 * (220-a)
that would be selection A.
you first subtract the subject's age from 220 to get (220-a).
you then take 75% of that (.75 * (220-a)).
