Remark
This is actually a six sided figure. That really doesn't matter, but it's interesting to observe. It goes a long way to explaining what is going on. The trick to exterior angles is that as long as the figure is convex ( a closed figure whose lines do not cross), the exterior angles add to 360.
Once you know that, then you know that this figure must have 6 exterior angles and no matter how they are made, their total is 360.
Equation
n + n + n + n + 90 + 90 = 360 Combine like terms.
Solution
4n + 180 = 360 Subtract 180
4n = 360 - 180
4n = 180 Divide both sides by 4
4n/4 = 180/4
n = 45
Note
Not a simple problem. Thanks for posting

"The Martin family's truck gets an average of 25 miles per gallon of fuel. Predict how many miles they will be able to get from 7 gallons of fuel by using equivalent rates." (Explain with fractions/ equivalent rate in detail pls)
Answers
Answer:
175 miles
Step-by-step explanation:
Average of 25 miles per gallon of fuel
Miles : gallons = 25 : 1
Predict how many miles they will be able to get from 7 gallons of fuel by using equivalent rates
Let x = number miles
Miles : gallons = x : 7
To find x
25 : 1 = x : 7
25/1 = x/7
Cross product
25*7 = 1*x
175 = x
x = 175 miles
Number miles = 175

Find f(-5) if f(x) = 5x + 11.
A) 4
B) 5
C) 6
Answers
Step-by-step explanation: Since f(x) = 5x + 11, we find f(-5)
by substituting a -5 in for the x in the function to get f(-5) = 5(-5) + 11.
Now just simplify the right side to get -25 + 11 or -14.
So f(-5) = -14.

Nicholas has a pepper shaker in the shape of a cylinder. It has a radius of 9 mm and height of 32 mm. How much pepper will for in the shaker
Answers
By using the fοrmula fοr the vοlume οf a cylinder, the pepper shaker can hοld apprοximately 8,159.15 cubic millimetres οf pepper.
What is the vοlume οf a cylinder ?The fοrmula tο calculate the vοlume οf a cylinder:
V = πr²h
where:
V = vοlume
r = radius
h = height
Tο calculate the vοlume οf the pepper shaker, we need tο use the fοrmula fοr the vοlume οf a cylinder.
In this case, we have:
r = 9 mm
h = 32 mm
Sο the fοrmula becοmes:
V = π(9 mm)²(32 mm)
V = π(81 mm²)(32 mm)
V = 81π(32) mm³
V ≈ 8,159.15 mm³
Therefοre, the pepper shaker can hοld apprοximately 8,159.15 cubic millimeters (οr milliliters) οf pepper.

During the annual black Friday sale,the OLX sold a price of ski boots at regular price of $245 at a discount of 40%the boots cost 96$, and expenses at 26% of the regular price, how much was the ski boots sold
Answers
Answer: $147
Step-by-step explanation:
The boots were sold at a 40% discount of the regular price of $245.
The price they were sold at is therefore:
= Price * ( 1 - discount)
= 245 * ( 1 - 40%)
= 245 * 60%
= $147

The square is shown with a side length of 8 inches.
The area of a square is s^2, which can also be written as s x s, where a is the length of the side.
Area of the square would be 8 x 8 = 64 square inches.
The area of a circle is pi x r^2, where r is the radius. R is given as 3 inches.
The area of the circle is 3.14 x 3^2 = 28.26 square inches.
The shaded area is the square minus the circle.
The shaded area = 64 - 28.26 = 25.74 square inches.
The answer is 25.74 square inches.
Look at my explanation to know the answer clearly.
So, we're supposed to find the area of the shaded part.
In the problem, the shaded part is the square, and the side is 8 in.
Let's apply this formula, A = L · W or A². So, we can multiply the Length and Width to get the area.
The length is 8.
Since we don't have a width, we can use A². We can find 8 to the 2nd power to get the answer.
8 to the 2nd power is 64. How?
1. Break the exponent down.
8² ⇒ 8 × 8
2. Solve.
8 × 8 = 64
Hence, 64 is the answer. Hence, 64 is the answer. Now, we'll need to find the circumference of the circle.
The formula for that is 2 π r²
The radius is 3 in, so let's multiply 2 by 3² by 3.14.
3² × 3.14 = 28.26
Lastly, subtract 64 by 28.26.
64 - 28.25 = 25.74
Hence, your final answer is 25.74in.
