T=5
4=2+2/5t
Subtract 2 from both sides.
2=2/5t
Multiply both sides by 5/2.
t=5
Answer:
$13,695.98
Step-by-step explanation:
We can use the continuous compound interest formula to solve:

<em>P = principal amount</em>
<em>r = interest rate (decimal)</em>
<em>t = time (years)</em>
<em />
First, lets change 8% into a decimal:
8% ->
-> 0.08
Now, lets plug in the values:


The account balance after 10 years will be $13,695.98
In one revolution of the wheel, a point on the edge travels a distance equal to the circumference of the wheel.
The wheel has radius 1 ft, so its circumference is 2π (1 ft) = 2π ft.
Then the point has a linear speed of
(1/4 rev/s) * (2π ft/rev) = 2π/4 ft/s = π/2 ft/s
Each bag of rice is going to have 1/8 of the original amount, or 1/8 of 45.
45/8 = 5.625.
Each rice bag will have 5.625 pounds of rice.
