Answer:
16.42 years
Step-by-step explanation:
Use the Future value formula; FV = PV (1+r)^t
PV= Initial amount deposited, 500
r= interest rate or discount rate, 2.5%
t = total duration of the investment, ?
FV= future value of account, 750
Plug in the numbers into the formula
750 = 500* (1+0.025)^t
divide both sides by 500
750/500 = 1.025^t
put ln on both sides
ln 1.5 = ln
ln 1.5 = t ln 1.025
0.4054651 = 0.0246926 t
Divide both sides by 0.0246926
0.4054651/0.0246926 = t
t = 16.42

Answer:
A: the same line
Step-by-step explanation:
khan academy
A + m = 54, m = a + 4 and, a + m = 54, - a + m = 4,
Combine the equations: 2m = 58
Now solve: 2m = 58, 2m/2 = 58/2, m = 29, therefore a = 24
Answer: 2 1/3

Answer:
12(1/4)
Step-by-step explanation:
5(1/2)+6(3/4)
Change to common denominator,
5(2/4)+6(3/4)
5+6=11 and (2/4) + (3/4) = 1 (1/4)
11 + 1 (1/4)= 12 (1/4)
