A = P (1 + r/n)ⁿˣ
A = the future value = $ 20,000
P = the principal investment amount = Not given
r = the annual interest rate (decimal) = 0.06
n = the number of times that interest is compounded per year = 12
x = the number of years = 10
$ 20,000 = P (1 + 0.06/12)¹²⁰
$ 20,000 = P (1 +0.005 )¹²⁰
$ 20,000 = P (1.005 )¹²⁰
$ 20,000 = 1.81·P
P = $ 20,000÷1.81
P = $ 11,049.72

add 25%
100%+25%=125%
125% of 82
percent means parts out of 100
125%=125/100=1.25
'of' means multiply
125% of 82 means
1.25 times 82=102.5

The difference in circumference between the goal and the center cross-section of a basketball is 26.4inches.
It is given that
Diameter of a basketball goal = 18inches
So, the radius will be 18/2 = 9inches
What is the circumference of a circle?
It is the length of the outer periphery of a circle equals 2*π*r, where r is the radius of the circle.
Circumference of goal = 2*π*9 = 56.57inches
Diameter of basketball = 9.6inches
So, the radius of basketball will be 9.6/2 = 4.8 inches
Circumference of cross-section of basketball = 2*π*4.8 = 30.17inches
So, the difference in circumference between the goal and the center cross-section of a basketball = 56.57-30.17 = 26.4inches.
Therefore, difference in circumference between the goal and the center cross-section of a basketball is 26.4inches.

100 in^2
area of a square = l*w
so length and width of the square both equal 10in
there are 4 squares going across the semi circle so...
diameter of semicircle is 10+10+10+10 =40in and radius is 20in
to find area of semicircle the formula is 1/2 pi r^2
so plug in the numbers 1/2(3.14) (20)^2 = 628 in ^2
now add that to area of big square part of window
40 inches length * 40 inches width = 1600in^2 (or you can just add them all up )
add up the areas now 1600+628= 2228 in^2
i think that is right
b) The next part's a little tricky, but just add 4 inches to the radius and 4 inches to all of the affected outer-rim squares. You should get 3016.32 in²

The height of the rectangular prism will be 25 feet.
What is the volume of the rectangular prism?
Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as
V = L x W x H
The volume of a rectangularprism is 300 ft³.
If the area of the base is 12 ft².
Then the height of the rectangular prism will be
We have
V = 300 ft³
L x W = 12 ft²
Then we have
300 = 12 x H
H = 25 feet
More about the volume of the prism link is given below.
