H varies directly as L. If H = 30 when L=60, determine H when L= 40. a) Write the variation equation.
b) Determine the value of the quantity indicated.
a) Choose the correct answer below.
O A. H=L
k.
O B. L=
H
O C. H=kL
w
k k
OD. H=*
b) H= |(Type an integer or a decimal.)

i) The variation equation     H =  k L

ii) The value of H = 20

iii) C)  H = k L

Step-by-step explanation:

Step(i):-

Given that H varies directly as L

                    H ∝ L

                   H =  k L

Given that H =30 and L = 60

          ⇒   30 = k (60)

Step(ii):-

Given that L = 40

The variation of the equation = H = k L ...(i)

 put L = 40 in equation (i)

the answer for this question is 38

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
