Answer:


Step-by-step explanation:
is the expression given to be solved.
First of all let us have a look at <u>3 formulas</u>:

Both the formula can be applied to the expression(
) during the first step while solving it.
<u>Applying formula (1):</u>
Comparing the terms of
with 

So,
is reduced to 
<u>Applying formula (2):</u>
Comparing the terms of
with 

So,
is reduced to
.
So, the answers can be:


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
ok so divide 1500 by 250 to determine how many boxes you need to by in 1 year
so that equals 6 then you multiply that by $30 to find the total cost of all the diapers per year so the is $180 per year and then multiply that by 3 to find the cost of all 3 years
So the answer is you will spend $540 in total
Jack has 2, Maria has 9, Paul has 5.
