Answer:
After 18 years, Zach's account balance will be $ 6,614.66.
Step-by-step explanation:
Given that Zach's parents put $ 1,500 in her bank account for college tuition at an interest rate of 8.25% compounded weekly, to determine what will be the balance after 18 years the following calculation must be performed:
1,500 x (1 + 0.0825 / 52) ^ 18x52 = X
1,500 x 1.00158653 ^ 936 = X
6,614.66 = X
Therefore, after 18 years, Zach's account balance will be $ 6,614.66.
If there are 4 trucks then the first truck weighs x
then x+2tons
then x+4tons
then x+6tons = 32tons
so 4x+12=32
-12 -12
/4 /4
x=5
so plug it back in
truck 1= 5tons or 10,000lbs
truck 2= 7tons or 14,000lbs
truck 3= 9tons or 18,000lbs
truck 4= 11tons or 22,000lbs
V = lwh
15(10.5)(4.5) = 708.75
