The right answer is Option A.

Step-by-step explanation:

Given,

Heart rate goal = I

Heart rate reserve = H

70% of H = $\frac{70}{100}H = 0.7H$

Resting heart rate = R

According to given statement,

70% of heart rate reserved is added to resting heart rate to calculate heart rate goal, therefore,

I = R + 0.7H

I=R+0.7H represents the given situation.

The right answer is Option A.

Quick please I really need this

Kipish [7]

Answer:

y = 39

Step-by-step explanation:

550 x $\pi$ = $\pi$ $r^{2}$ x 11 + y

550 x $\frac{7}{22}$ = $\frac{7}{22}$ x 11 x 11 + y

550 x $\frac{7}{22}$ x $\frac{22}{7}$ = 11 x 11 + y

550 = 11 x 11 + y

$\frac{550}{11}$ = $\frac{11}{11}$ x 11 + y

50 = 11 + y

50 - 11 = y

39 = y
