Set up two seperate equations
first the volume equation
1728=length*width*height
we know the height is 6ft
1728=L*W*6
divide both sides by 6
288=L*W
then the second equation
L=4.5W
if one side is 4.5 times larger
then take that and plug it back into the first equation
288=(4.5W)*W
288=(4.5)w^2
divide both sides by 4.5
64=w^2
so w=8
then plug that back into the last equation
L=4.5(8)
L=36

Answer:
Option B. 3 years.
Step-by-step explanation:
Sylvio loaned a friend $1,500 at a simple annual interest rate of 5%.
Formula of simple interest = I = P(rt)
I = Interest ($225)
P = Principal amount ( $1,500)
r = 5% = 0.05
t = time ( ? )
Now put the values to find the years.
225 = 1500( 0.05t)
225 = 75t
75t = 225
t =
t = 3
It will take 3 years to repay him if Sylvio earned $225 in interest.
Answer:
Yes, but none of the answer choices exactly describe the proportional relationship. The closest choice is A.
Step-by-step explanation:
The form of the equation of a proportional relation is y = kx, where k is the coefficient.
In the given case y =1/2x, where k = 1/2, so it represents proportional relationship.
<u>Answer choices:</u>
A. Yes, because the coefficient of x is positive
- - it is yes, but the coefficient can also be negative
B. No, because it is not in the form y=kx
- - it is no, as it is in the for of y = kx
C. No, because its graph does not pass through the origin
- - no, it doesn't matter if the graph passes through the origin or not
D. Yes, because its graph is a line that passes through the origin
- - no as it is not necessary the graph to pass through the origin
