Answer:
Part A
12 months a year means
%74.5 x 12 = $894
Part B
4 weeks in a month means
$74.5 ÷ 4 = $18.625
But rounded to the nearest penny. . .
$18.62
because in the thousandths place was a 5 and you round up when there is a 5 or above
Part C
We will go with 31 days in a month, but I will also do 30 for you
$74.5 ÷ 30 = $2.48333
But rounded to the nearest penny. . .
$2.48
because you round down when there is anything less than a 4
$74.5 ÷ 31 = $2.40322580645
But rounded to the nearest penny. . .
$2.40
because you round down when there is anything less than a 4

A paper container in the shape of a right circular cone has a radius of 3 inches and a height of 8 inches. Determine and state thr number of cubic inches in the volume of the cone, in terms of π.
Given:
Radius of the cone = 3 inches
Height of the cone = 8 inches
To find:
The volume of the cone, in terms of π.
Solution:
We know that, the volume of a cone is:
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Putting [tex]r=3,h=8[/tex], we get
[tex]V=\dfrac{1}{3}\pi (3)^2(8)[/tex]
[tex]V=\dfrac{1}{3}\pi (9)(8)[/tex]
[tex]V=\dfrac{72}{3}\pi [/tex]
[tex]V=24\pi [/tex]
Therefore, the volume of the cone is [tex]24\pi[/tex].

A certain forest covers an area of 3900 km^2. Suppose that each year this area decreases by 6.75%. What will the area be after 12 years
Answer:
1686
Step-by-step explanation:
Rate of reduction = 100 - 6.75 = 93.25%
After 12 years, the reduction in trees = 0.9325^12 = 0.432301
Area after 12 years = 3900 x 0.432301 = 1686

After winning a soccer game, the coach took the team out for ice cream cones. He spent $21 on 12 single-scoop ice cream cones. If all the ice cream cones cost the same amount, what was the cost of one ice cream cone?
Answer:
Unitary cost= $1.75
Step-by-step explanation:
Giving the following information:
He spent $21 on 12 single-scoop ice cream cones.
To calculate the unitary cost, we need to use the following formula:
Total cost= number of units*unitary cost
Unitary cost= total cost / number of units
Unitary cost= 21 / 12
Unitary cost= $1.75
