Step-by-step explanation:
The constant of proportionality is the ratio of the cost to the number of pounds of walnuts. In other words, it is the price of one pound of walnuts.
$10.92 / 4 lb = $2.73 / lb
Answer:
.75 * 6 = 4.5 minutes
.75 is 3/4 multiply by 6 because 6/6 is a whole tank of gas.
Sawyers tank takes 4.5 minutes to be filled up.
Answer: s = -4
s/4 + 15 = 14
We can subtract 15 from both sides:
s/4 = -1
We can multiply both sides by 4:
s = -4
v=pi.r^2.h
1728=3.14*22r^2
1728/69.08=r^2
r^2=25.0144
r=5
