Compound interest formula is
where A is the amount after T years, P is the principal amount you start with, R is the interest rate, and N is the amount of compounding periods. Semi-annually means we only have 2 compounding periods.
Now plug in:
which becomes
. Plug this into your calculator.
A = 5788.125. Because it's money, you would round to the nearest penny.
A = 5,788.13 dollars
Answer:
Step-by-step explanation:
density of oil, d = 30 lb/ft³
Volume of tank, V = l x w x h = 1 x 2 x 1 = 2 ft³
mass of oil, m = Volume x density of oil = 1 x 30 = 30 lb
Work = m x g x h = 30 x 32 x 3 = 2880 units

Answer:
58 and 42.
Step-by-step explanation:
Let the 2 numbers be x and 100-x.
Also let x be the largest number, so
x ≥ 100 - x + 16 ( 'At least 16' means equal to 16 or greater than 16).
Add in x to both sides:
x + x ≥ 100 + 16
2x ≥ 116
x ≥ 58.
But since the sum of the 2 numbers is 100, x must be 58 and the other number is 42.
