Answer:

The measure of each exterior angle of a regular octagon is A. 45°

Step-by-step explanation:

To find the solution to the problem above, we will follow the steps below;

To find the exterior angle of a regular polygon we can simply divide 360 by the number of sides of that polygon or we can simply use the formula below

Each Exterior angle = 360/n

where n is the number of sides

an octagon is an eight-sided polygon. This implies that the number of side =8

Each Exterior angle = 360/n

                                  =360/8

                                  =45°

The measure of each exterior angle of a regular octagon is 45°

Because an octagon consists of eigth sides/edges, and 360 degrees is the total sum of the angles, we simply divide 360 by 8:

360/8 = 45.

Option A, 45 degrees

If a car dealership buy as car for $9000, and wants to make a 45% profit, how much do they need to sell the car for? ​
Degger [83]

Answer:

A car dealership needs $13050 to sell the car to earn the 45% profit if a car dealership buys a car for $9000.

Step-by-step explanation:

Car cost = $9000

Profit percentage = 45% profit

Thus,

Profit amount = 45% of 9000

                       = 45/100 × 9000

                       = 0.45 × 9000

                       = $4050

In order to determine how much a car dealership needs to sell the car to earn the 45% profit, all we need is to add the profit amount i.e. $4050, and the car cost i.e. $9000.

i.e.

Car cost + Profit amount = $9000 + $4050

                                         = $13050

Therefore, a car dealership needs $13050 to sell the car to earn the 45% profit if a car dealership buys s car for $9000.

92.4 is 150% of what number?
Ad libitum [116K]
1. We assume, that the number 92.4 is 100% - because it's the output value of the task. 
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 92.4 is 100%, so we can write it down as 92.4=100%. </span>
<span>4. We know, that x is 150% of the output value, so we can write it down as x=150%. </span>
5. Now we have two simple equations:
1) 92.4=100%
2) x=150%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
92.4/x=100%/150%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 150% of 92.4

92.4/x=100/150
<span>(92.4/x)*x=(100/150)*x       - </span>we multiply both sides of the equation by x
<span>92.4=0.666666666667*x       - </span>we divide both sides of the equation by (0.666666666667) to get x
<span>92.4/0.666666666667=x </span>
<span>138.6=x </span>
x=138.6

<span>now we have: </span>
<span>150% of 92.4=138.6</span>
