Answer: approximately 4478.46096908264 square cm.
==========================================================
Explanation:
I'm assuming this is a regular 12-sided polygon
The area formula for regular polygons is
[tex]A = 0.25n*s^2*\cot(180/n)[/tex]
where in this case we have n = 12 sides and each side is of length s = 20
So,
[tex]A = 0.25n*s^2*\cot(180/n)\\\\A = 0.25*12*(20)^2*\cot(180/12)\\\\A = 0.25*12*(20)^2*\cot(15)\\\\A = 0.25*12*(20)^2*\frac{1}{\tan(15)}\\\\A \approx 4478.46096908264\\\\[/tex]
The area of this regular polygon is approximately 4478.46096908264 square cm.
Make sure your calculator is in degree mode when computing that value of cot(15) or 1/tan(15).

A distance of 2 inches on a map represents an actual distance of 3 miles. The map shows a scale
drawing of a rectangular plot of land. The width of the plot of land on the map is 6 inches. What is the
actual width, in miles, of the plot of land?
Enter your answer in the space provided.
Answer:
9
Step-by-step explanation:
6 divided by 2 equals 3 then you multiply 3 by 3 which equals 9.
Hope this helps!!!!!!!!!!
Be safe!!!!!!!
Answer:
9 miles
Step-by-step explanation:
Given scale: 2 in = 3 miles
⇒ 1 in = 1.5 miles
If the width of the plot of land is 6 inches, then to calculate the actual width multiply 6 by 1.5:
actual width = 6 × 1.5 = 9 miles

Question 9 of 10
A system of two equations is shown below. What will you need to multiply the
top equation by in order to solve this system using the elimination method?
X +2y = 11
6X + 4y = 34
A. 6
• B. -2
C. 2
( D. -4
Answer:
by 6
Step-by-step explanation:
Isolate x for x + 2y= 11: x= 11- 2y
Substitute x =11 -2y
6(11 - 2y) + 4y = 34|
Simplify
[66 -8y= 34]
Isolate y for 66 - 8y= 34: y =4
For x = 11 - 2y
Substitute y = 4
X= 11-2 x 4
Simplify
X=3
The solutions to the system of equations are:
X=3,y=4
Find the midpoint of the line segment joining the points C= (4,7) and D= (-2,-3)
Answer:
(1, 2)
Step-by-step explanation:
Hi there!
We are given two points - (4, 7) and (-2, -3)
We want to find the midpoint between these two points
The midpoint can be found using the formula [tex](\frac{x_1 + x_2}{2}, \frac{y_1+y_2}{2})[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have everything we need to find the midpoint, but let's label the values of the points to avoid any confusion & mistakes
[tex]x_1=4\\y_1=7\\x_2=-2\\y_2=-3[/tex]
Now substitute into the formula
[tex](\frac{x_1 + x_2}{2}, \frac{y_1+y_2}{2})[/tex]
[tex](\frac{4+ -2 }{2}, \frac{7+-3}{2})[/tex]
The pluses can be replaced with minus signs:
[tex](\frac{4 -2 }{2}, \frac{7-3}{2})[/tex]
Now subtract
[tex](\frac{2 }{2}, \frac{4}{2})[/tex]
Divide
(1,2)
The midpoint is (1, 2)

Nevaeh pays a total of $24
for two sets of paint brushes. Each set costs the same amount of money and contains three paint brushes.
What is the cost per paint brush?
$12
12 dollars
$8
8 dollars
$4
4 dollars
$3
The cost per paint brush is $4 if the Nevaeh pays a total of $24
for two sets of paint brushes, and each set costs the same amount of money and contains three paint brushes.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
Nevaeh pays a total of $24 for two sets of paint brushes. Each set costs the same amount of money and contains three paint brushes.
The cost for each set = 24/2 = $12
In each sets of paint brushes there are total of 3 brushes which cost $12
So, each brush cost = 12/3 = $4
Thus, the cost per paint brush is $4 if the Nevaeh pays a total of $24
for two sets of paint brushes, and each set costs the same amount of money and contains three paint brushes.

A poll is taken at four different grocery stores to determine how far customers drive to shop at their store. The following information was gathered at the four stores. Customers That Drive < 5 miles Store W 52 of 100 Store X 68 of 75 Store Y 59 of 120 Store Z 28 of 50 If one customer is selected at random from each store, at which store would selecting a customer that drives less than 5 miles be a likely event?
Due to the higher proportion of customers driving less than 5 miles, it would be a likely event at store X.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
For each store, the proportion of customers driving less than 5 miles is given by:
Store W: 52/100 = 0.52.Store X: 68/75 = 0.9068.Store Y: 59/120 = 0.4917.Store Z: 28/50 = 0.56.Hence, due to the higher proportion of customers driving less than 5 miles, it would be a likely event at store X.

Joshua borrowed $2,200 for one year and paid $132 in interest. The bank charged him a service charge of $21. What is the finance charge on this loan?
Joshua borrowed $2,200 for one year and paid $132 in interest. The bank charged him a service charge of $21. The finance charge on this loan is 6.9%.
What is APR?Suppose there is an initial amount as P.
The interest, or say charge on it is applied annually as 'C' amount.
Taking how much percent of P is C, we get:
[tex]APR = \dfrac{C}{P} \times 100[/tex]
Given;
Principal =$2,200
interest = $132
Service charge = $21.
To find finance charge we use
Finance charge (FC) = interest + service charge(SC)
= $132 + $21
= $153
Therefore
APR = Finance charge / Principal
= $153 / $2200
= 0.069 or 6.9%
Therefore, The finance charge on this loan is 6.9%.

VOLUME OF RECTANGULAR PRISMS
4 cm
1
7.5 cm
18 cm
Answer: 540 cm³
Step-by-step explanation:
The volume of a rectangular prism can be found with:
V = L * W * H
-> L is the length
-> W is the width
-> H is the height
V = L * W * H
V = 18 cm * 7.5 cm * 4 cm
V = 540 cm³
The volume is 540 cm³.
