D=C(1+rt/100) solve for r

xz_007 [3.2K]

Answer:

r= −100c+100d/ct

Step-by-step explanation:

d=c(1+rt/100)

1/100crt+c=d

1/100crt+c+−c=d+−c

1/100crt=−c+d

$\frac{1/100crt}{ct/100}$ = $\frac{-c + d}{ct/100}$

what is an equation for the line that passes through the points (0,-4) (7,11) in slope-intercept form

fomenos

Answer:

y=15/7x-4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(11-(-4))/(7-0)

m=(11+4)/7

m=15/7

y-y1=m(x-x1)

y-(-4)=15/7(x-0)

y+4=15/7(x)

y+4=15/7x

y=15/7x-4

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.
