calculate the number of sides of a regular polygon with sum interior angles of 2160°.
Answer:
14 sides
Step-by-step explanation:
The sum of all interior angles of a polygon = (n - 2)180°
2160° = (n - 2)180°
[tex]n - 2 = \frac{2160 \degree}{180 \degree} \\ \\ n - 2 = 12 \\ \\ n = 12 + 2 \\ \\ n = 14[/tex]
Hence, the polygon has 14 sides.

How to determine the length of the third sideFrom the question, we have the following parameters that can be used in our computation:
A right triangle
This means that we can calculate the third length using the Pythagoras theorem
using the above as a guide, we have the following:
x = √(15² - 9²)
Evaluate the exression
x = 12

Rearrange
C=d+2/3
to make d the subject.
Answer:
d = C - 2/3
Step-by-step explanation:
Subtract 2/3 from both sides of the equation:
C = d + 2/3
-2/3 -2/3
-----------------
C - 2/3 = d
After rearranging the expression and taking the subject d is d = C - 2/3 or d = (3C-2)/3.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
C=d + 2/3
C - 2/3 = d (subtract both side by 2/3)
or
d = C - 2/3 or
d = (3C-2)/3
Thus, after rearranging the expression and taking the subject d is d = C - 2/3 or d = (3C-2)/3.

How much paper is needed to cover a rectangular bulletin board that is 29 in. wide and 37 in.
high?
A. 132 in2
B. 536.5 in?
C. 957 in?
D. 1,073 in?
Answer: The answer is D
The amount of paper needed to cover the rectangular bulletin board is 1,073 square inches. The correct answer is: D. 1,073 in²
To calculate the amount of paper needed to cover a rectangular bulletin board, we need to find the area of the board.
Given:
Width of the bulletin board = 29 inches
Height of the bulletin board = 37 inches
To find the area, we multiply the width by the height:
Area = Width * Height
Area = 29 inches * 37 inches
Area = 1,073 square inches
Therefore, the amount of paper needed to cover the rectangular bulletin board is 1,073 square inches.
The correct answer is:

The General Social Survey asked a large number of people how much time they spent watching TV each day. The mean number of hours was 2.98 with a standard deviation of 2.66. Assume that in a sample of 40 teenagers, the sample standard deviation of daily TV time is 1.9 hours, and that the population of TV watching times is normally distributed. Can you conclude that the population standard deviation of TV watching times for teenagers is less than 2.66
Answer:
Yes, we can conclude that the population standard deviation of TV watching times for teenagers is less than 2.66
Step-by-step explanation:
H0 : σ² = 2.66²
H1 : σ² < 2.66²
X²c = (n - 1)*s² ÷ σ²
sample size, n = 40
Sample standard deviation, s = 1.9
X²c = ((40 - 1) * 1.9²) ÷ 2.66²
X²c = 140.79 ÷ 7.0756
X²c = 19.897
Using a confidence level of 95%
Degree of freedom, df = n - 1 ; df = 40 - 1 = 39
The critical value using the chi distribution table is 25.6954
Comparing the test statistic with the critical value :
19.897 < 25.6954
Test statistic < Critical value ; Reject the Null
Hence, we can conclude that the population standard deviation of TV watching times for teenagers is less than 2.66

Sue needs to drive 372 miles to visit her aunt. She stopped at a gas station one-third of the way in to her trip. How many miles has she traveled?
Answer:
Sue has traveled 124 miles.
Step-by-step explanation:
Here, the distance covered by Sue is a fraction of the total distance to be covered.
The total distance to her aunt's = 372 miles
but the gas station is at one-third of the distance to be covered.
Thus,
Miles traveled by Sue = [tex]\frac{1}{3}[/tex] x 372
= 124
Miles traveled by Sue = 124 miles.
Therefore Sue has traveled 124 miles.

She learned that her bank would pay her 5% on her money in her savings account if she had at least $1,000 in it. Brenda had $2,345 in her savings account at the end of the year. How much interest did Brenda get from her bank.
A) $117.25
B) $1,172.59
C) $1.72
D) $17.25
Answer:
$117.25
Step-by-step explanation:
To solve, multiply the interest by the total amount in savings.
You can calculate simple interest in a savings account by multiplying the account balance by the interest rate by the time period the money is in the account. Here's the simple interest formula: Interest = P x R x N. P = Principal amount (the beginning balance).
Brenda get $117.25 as interest from her bank.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. With the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Brenda learned that her bank would pay her 5% on her money in her savings account if she had at least $1,000 in it.
Brenda had $2,345 in her savings account.

What does it mean to say that two line segments are congruent?Two line segments are collinear if they lie on a line. Two line segments are congruent when they have equal measures.
What is a parallel line?Parallel lines are lines in a plane that are always the same distance from each other. Parallel lines never intersect, while perpendicular lines are those that intersect at a right angle (90 degrees).
In this way, we can identify that the only lines that represent a congruent line are lines A and H.
