Answer:
To calculate the number of sides of the polygon, divide 360 by the amount of the exterior angle. For example, if the exterior angle is 60 degrees, then dividing 360 by 60 equals 6, which is the number of sides the polygon has.
How do you plot a graph given an equation?.
To plot a graph an equation starts by determining the equation's variables. Select the variables' possible ranges of values.
Plot the equation using a graphing calculator or graphing software.
Enter the equation into the graphing calculator if you're using one. Enter the equation in the graphing software if you're using one. Modify the scale and labels of the graph to your specifications.
Draw the points on the graph by inputting the variables' values. Join the points together to create a graph.
All you have to do is change the variables in this formula to graph a linear equation. A linear equation is the simplest form of graph to create because no computations are required before drawing the graph. Draw a simple Cartesian coordinate plane.
Start at the y-intercept to plot the slope. The fraction's numerator is the rise (the number of spaces up), and its denominator is the run (the number of spaces to the side).

Check Right Side of both equations
Answer: The right side of the first equation is 78, and the right side of the second equation is -72. Both equations are correct.
In the first equation, 2(3b+6) = 78, if we solve for b we get b= 11.
In the second equation, -2(6c-3) = -72, if we solve for c we get c = 6.5.

$34.50dollar sign, 34, point, 50.
The price of one coat is $46.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number. So the percentage actually means a part per 100.
Given that,
a store has 25% off sale on coats.
Discounted price of one coat = $34.50
We have to find the original price of the coat. Let it be x.
x - (25% x) = 34.5
x - 0.25x = 34.5
0.75x = 34.5
x = 46

How do you find the first term?.
To find the first term can be calculated an = a1 + d(n - 1).
The difference between every two successive terms in a sequence is the same; this is known as an arithmetic progression (AP). It is possible to obtain a formula for the nth term of the AP using this kind of development. A good example of an arithmetic progression (AP) is the series 2, 6, 10, 14,..., which follows a pattern in which each number is created by adding 4 to the previous term. The nth term in this series equals 4n-2. You may get the terms of the series by changing the nth term to n=1,2,3,... i.e.,
first term = 4n-2 = 4 when n = 1 (1)
-2 = 4-2=2
Second term for n = 2 is 4n-2 = 4. (2)
-2 = 8-2=6
When n is 3, the third term is 4n-2 (3)

What is the measure of an angle if it is five times?.
The measure of an angle if it is five times its complement: 75 degrees
Let us assume that the complement of the angle measures m degrees.
we have been given the measure of the angle is five times its complement.
So we get the measure of the angle = 5 × m
We know that two angles are complementary when their measures add to 90 degrees.
So we get an equation, m + 5m = 90
We solve above equation to find the value of m.
m + 5m = 90
6m = 90
m = 90/6
m = 15 degrees
This means, the measure of complement of the angle is 15 degrees.

How do you simplify radicals explain and give examples?.
Simplifying radicals is the process of reducing a radical expression to its simplest form. There are several ways to simplify radicals, but the most common method is to factor .
The number or expression inside the radical sign and extract any perfect nth root factors.For example: √36 = √(36) = √(6*6) = √(6^2) = 6
Here, 36 can be factorized into 6*6, and since 6 is a perfect square, we can simplify the radical as 6.
Another example: √100 = √(100) = √(10*10) = √(10^2) = 10
Here, 100 can be factorized into 10*10, and since 10 is a perfect square, we can simplify the radical as 10.
Another way to simplify radicals is to use the product property of radicals which states that: √(a*b) = √(a) * √(b)
For example: √(1215) = √(12) * √(15) = √(4355) = √(43) * √(55) = 2√(3) * 5 = 6√(3)
Here, 1215 can be factorized into 4355. And since 43 is a perfect square, we can simplify the radical by taking the square root of 43 and 5*5.
You can simplify radicals as much as possible by applying these methods.
It's important to note that not all radicals can be simplified completely, in some cases we can simplify the radical as much as possible but still have an irrational number inside the radical.
Simplifying radicals is a useful process in algebra and trigonometry, it helps to simplify the expressions and make calculations easier.

Class Interval Frequency f Mid-value x fx

50-60 m 55 55m
60-70 6 65 390
70-80 4 75 300
∑f = 148+m ∑fx = 4300+55m
The mean of the data set shown in the table above is 31.
mean = ∑fx/∑f
Substitute the known values in the above formula, and we get
31 = (4300+55m)/(148+m)
31(148+m) = 4300+55m
4588 +31m = 4300+55m
55m - 31m = 4588 - 4300
24m = 288
m = 288/24
m = 12
Thus, the required frequency is 12 for the class interval 50-60.
(ii)The table below summarizes the data about the heights of students in a class.
Height (in cm) (x) d = (x -A)/10 Number of students (f) fd

150-160 155 0 14 0
160-170 165 1 20 20
170-180 175 2 12 24
∑f = 60 ∑fd = 22
Mean = A + ∑fd/∑f
Mean = 155 + 22/60
Mean = 155 + 0.3
Mean = 155.3
So, the mean height of students in a class is 155.3.
(iii) Given that the mean of data is 27 and the mode is 45
Mode = 3Median - 2Mean
45 = 3Median - 2(27)
45 = 3Median - 54
3Median = 54 + 45
Median = 99/3
Median = 33
Thus, the median of the given data is 33.

Are 1 3 and 2 7 equivalent fractions?.
No, 1/3 and 2/7 are not the equivalent fractions.
In mathematics, equivalent fractions are those with the same denominator and differing numerators. For instance, because 2/4 and 3/6 are both equal to 1, they are both comparable fractions. Part of a whole is a fraction. Identical portions of the whole are represented by equivalent fractions.
Every fraction has an equivalent fraction, which can be found by multiplying the numerator and denominator by the same integer. In spite of their visual differences, equivalent fractions are those that indicate the same value. For instance, if you take a piece of cake, divide it into two equal pieces, then eat one of them, you will have consumed half of the cake.
