Answer:
The constant of variation is 5.
Step-by-step explanation:
In direct variation, as y varies directly with x, the standard equation is
y = kx,
where k is the constant of variation.
In your case, we use R and S. R varies directly with S, so we have
R = kS
We know that when S = 16, R is 80, so we plug in those values and solve for k, the constant of variation.
R = kS
80 = k(16)
k = 80/16
k = 5
Answer:
a. V = 10*8*x
b. V= 10*8*22.5
Step-by-step explanation:
b. V= 1800
Answer:
Step-by-step explanation:
(5f-3)(-2)
-10f + 6 = 0
f= 6 + 10
f = 16
52-24=28 books were nonfiction
You must get the ratio if nonfiction to fiction
28/24= 7/6
