Answer:
14.1 years
Step-by-step explanation:
Use the compound interest formula and solve for t. Logarithms are involved.
A = P(1 +r/n)^(nt)
amount when P is invested for t years at annual rate r compounded n times per year.
Using the given values, we have ...
13060 = 8800(1 +0.028/365)^(365t)
13060/8800 = (1 +0.028/365)^(365t) . . . . divide by P=8800
Now we take logarithms to make this a linear equation.
log(13060/8800) = (365t)log(1 +0.028/365)
Dividing by the coefficient of t gives us ...
t = log(13060/8800)/(365·log(1 +0.028/365)) ≈ 0.171461/0.0121598
t ≈ 14.1
It would take about 14.1 years for the value to reach $13,060.

Answer:
10 centimeter=92 milimeter
Step-by-step explanation:
we know that
one centimeter contains 10 milimeter or
1 centimeter is equal to 10 milimeter
1 centimeter=10 milimeter
we have to find
how many milimetersare there in 9.2 milimeters
9.2 centimeter=? milimeter
for this we will multiply by 9.2 on both sides
1 centimeter=10 milimeter
9.2 centimeter=10*(9.2)=92 milimeter
10 centimeter=92 milimeter
Answer:
3 hours
Step-by-step explanation:
The rate of bus is 50
The rate of car is 55
Which means, per hour, the Car catches up by 55 - 50 = 5 miles
Since, the car starts AFTER the bus has already travelled 15 miles, the CAR IS BEHIND by 15 miles. To catch up these 15 miles (at the rate of catching up 5 miles per hour), the car would need:
15/5 = 3 hours to catch up with the BUS
<u>Note:</u> we use the formula
d = rt
where d = distance
r is rate
t is time
Thus, we had:
d = rt
t = d/r
t = 15/5
t = 3
Thus, after 3 hours, the car with catch up with the bus
