The cost per gallon would be 3.85$ which at this time is fairly expensive
Answer:
See below.
Step-by-step explanation:
I = PRT/100 will do it.
I = Simple interest.
P = Principal ( Intial Amount invested).
R = Rate (as a percent).
T = time invested.
The above formula gives the amount of interest, If you want to find the interest rate knowing all the other values you have to solve for R:
I = PRT/100
100 I = PRT
R = 100I / PT is the formula .
Answer:
12000 cubic meters
Step-by-step explanation:
v=(1/3)(900)(40)
Best to multiply by (y+1)(y-1) since on one side of the equation you have something divided by (y+1) and on the other something over (y²-1). since (y+1)(y-1) expanded is y²-1 this would work.
