With compounded continuously the formula is
A=pe^rt
A future value?
P present value 8500
R interest rate 0.0675
T time 25 years
E constant
A=8,500×e^(0.0675×25)
A=45,950.57
9/15 as a percent is 60%, so D.
4 1/5 as a percent is 420%, so B.
Answer:
It is number four
Step-by-step explanation: when you have a dividing one such as this you subtract the exponents which would give you 9^-5 but you can’t have a negative so make a fraction and its a positive
Answer:
The child has 6 dimes and 5 quarters.
Step-by-step explanation:
Let q and d represent the number of quarters and of dimes respectively.
Then q + d = 11 (Equation A), and ($0.25/quarter)q + ($0.10/dime)d = $1.85 (Equation B).
Multiply the 2nd equation by 100 to remove the decimal fractions:
25q + 10d = 185 (Equation C)
Now multiply the 1st equation by -10 to obtain -10q - 10d = -110 (Equation D), and combine this result with Equation C:
-10q - 10d = -110
25q + 10d = 185
--------------------------
15q = 75, and so q = 75/15 = 5.
According to Equation A, q + d = 11. Replacing q with 5, we get:
5 + d = 11, and so d = 6.
The child has 6 dimes and 5 quarters.
The answer should be option C.
