The sum of the exterior angles of a polygon = 360°
Divide this by the value of 1 exterior angle to find the number of sides n
n = 360 ÷ 9 = 40
Answer:
Let the number of sides=x
As we know that in a polygon
Number of sides=40.
B. 8
C. 512
D. 56
The requried simplified value of z is given as z = 8. Option B is correct.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given expression,
8z = 64
divide both sides by 8
8z / 8= 64 /8
z = 8
Thus, the requried simplified value of z is given as z = 8. Option B is correct.

$8370 of the deposit money $9000 is the money the bank is free to lend given that the reserve rate is 7%. This is obtained by finding 7% of deposit money and subtracting the answer from the deposit money.
Given that, deposit = $9000
reserve rate = 7%
First we have to find 7% of $9000,
7% of $9000 = 7/100 × $9000
= $630
Money the bank is free to lend, $9000 - $630 = $8370
Hence $8370 of the deposit money $9000 is the money the bank is free to lend given that the reserve rate is 7%.

To find the number of strings of lights needed for the square patio, divide the perimeter of the square by the length of each string of lights. Round up to the nearest whole number.
To find the number of strings of lights needed, we need to divide the perimeter of the square patio by the length of each string of lights. Since the patio is a square, all sides are equal in length. To find the side length, we can take the square root of the area.
In this case, the area is 225m², so the side length of the square patio is √225m = 15m. The perimeter of the square is 4 times the side length, which is 4 × 15m = 60m. Dividing the perimeter by the length of each string of lights, we get 60m ÷ 25m = 2.4. Since we can't have a fraction of a string of lights, we round up to the nearest whole number. Therefore, 3 strings of lights are needed.
