20. Find the measure of each interior angle AND each exterior angles of the following regular polygons. Show your work. a. Pentagon b. 16-gon c. Dodecagon
Answers
Interior angle:
5 sides => form 5 triangles => central angle: 360 / 5 = 72°
interior angle = 2x
angles in every triangle: x => x + x + 72° = 180°
=> 2x = 180° - 72° = 108°
Answer 108°
Exterior angles = 360° / number of sides = 360° / 5 = 72°
Answer: 72°
b. 16 - gon

which of the following is the solution to the equation c + (4-3c) - 2 = 0
Answers
we open the parenthesis
c+4-3c-2=0
-2c+2=0 subtract -2
-2c=-2 multiply by -1
2c=2
c=1
Final answer:
The solution to the equation c + (4 - 3c) - 2 = 0 is found by simplifying and solving for c, which results in c = 1.
Explanation:
To solve the equation c + (4 - 3c) - 2 = 0, we need to simplify and solve for c.
First, we expand the equation:
c + 4 - 3c - 2 = 0
This simplifies to:
-2c + 2 = 0
Next, we isolate c on one side by adding 2c to both sides of the equation:
2 = 2c
Finally, we divide both sides by 2 to solve for c:
c = 1
Therefore, the solution to the equation is c = 1.

A 12 sided die, numbered 1 to 12 is rolled. Find the probability that the roll results in an odd number or number less than 4
Answers
Answer:
6/12+3/12-2/12=.583
Step-by-step explanation:
6/12 amount of odd numbers
3/12 numbers less than 4
2/12 the amount of numbers that overlap
The probability that the roll results in an odd number or number less than 4 is 3/4.
Given that, a 12 sided die, numbered 1 to 12 is rolled.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
Total number of outcomes = 12
Odd numbered sides = {1, 3, 5, 7, 9, 11} = 6
Number less than 4 = {1, 2, 3} = 3
Probability of getting an odd number = 6/12
Probability of getting a number less than 4 = 3/12
So, probability = 6/12 + 3/12
= 9/12
= 3/4
Therefore, the probability that the roll results in an odd number or number less than 4 is 3/4.

Number of shaded triangles in the second figure = 3
Number of shaded triangles in the third figure = 9
If we observe these values, we can conclude that a Geometric Series is being formed.First number is multiplied by 3 to get the second number and second number is multiplied by 3 to get the third number. So the summation can be expressed using the Geometric Series.
The summation uses the general term to express the sum over the interval. So first we find the general term of geometric series.
First term of the series = 1
Common ratio = 3
So, the general term of the series will be: [tex]1(3)^{n-1} [/tex]
This general term gives the terms of given geometric series for different values of n. For n = 1, we will have the first term which will is 1. Similarly for n=2, we will have the second term which is 3.
So the summation will start with first term and end on 15th term. Therefore, correct summation for this case is expressed by first option.

Answers
Step 1: Move all similar terms (r) to the same side of the equation by
subtracting "r" from each side of the equation
0.25r - 0.125 + 0.5r - r = 0.5
Move terms without r to the other side of the equation, by adding +0.125 to each side of the equation
0.25r + 0.5r - r = 0.5 + 0.125
Add similar terms, note that r is equal to 1r
0.75r - 1r = 0.625
-0.25r = 0.625
Solve for r by dividing both sides of the equation by -0.25

C. p2−4p−45=0
D. p^2+4p−21=0
Answers
p^2 - 21 = 4(x^2 + 6)
p^2 - 21 = 4p

A <<<< answer.
Final answer:
The equation equivalent to (x^2+6)^2-21=4x^2+24 in terms of p is A. p² - 4p - 21 = 0.
Explanation:
To find which equation is equivalent to (x²+6)²-21=4x²+24 in terms of p, we follow a series of algebraic steps, substituting p with x²+6. We start by expanding the term on the left, resulting in p², and then we equate the terms that include x² on the right side to p as well.
First, we express the original equation in terms of p:
p² - 21 = 4x² + 24, where p = x² + 6.
Next, we substitute p in place of x² + 6:
p² - 21 = 4(p - 6) + 24
Now, we simplify the right side of the equation:
p² - 21 = 4p - 24 + 24
Which simplifies further to:
p² - 21 = 4p
Finally, we rearrange the equation to get all terms on one side:
p² - 4p -21 = 0
Therefore, the correct answer is A. p² - 4p - 21 = 0.

Two buses leave a station at the same time and travel in opposite directions. One bus travels 12 mi/h faster than the other. If the buses are 690 mi apart after 5 hours, what is the rate of each bus mi/h?
Answers
The correct rates of the buses are 63 mi/h for the faster bus and 51 mi/h for the slower bus.
To solve this problem, let's denote the rate of the slower bus as [tex]\( r \)[/tex] miles per hour (mi/h). Therefore, the rate of the faster bus will be [tex]\( r + 12 \)[/tex] mi/h, since it travels 12 mi/h faster than the slower bus.
Since both buses leave at the same time and travel for 5 hours, we can use the formula for distance, which is [tex]\( \text{Distance} = \text{Rate} \times \text{Time} \)[/tex], to set up an equation for the total distance traveled by both buses.
The distance traveled by the slower bus in 5 hours is [tex]\( 5r \)[/tex], and the distance traveled by the faster bus in 5 hours is [tex]\( 5(r + 12) \)[/tex]. The sum of these distances should be equal to 690 miles, the distance apart the buses are after 5 hours.
So we have the equation:
[tex]\[ 5r + 5(r + 12) = 690 \][/tex]
Now, let's solve for [tex]\( r \)[/tex]:
[tex]\[ 5r + 5r + 60 = 690 \][/tex]
[tex]\[ 10r + 60 = 690 \][/tex]
[tex]\[ 10r = 690 - 60 \][/tex]
[tex]\[ 10r = 630 \][/tex]
[tex]\[ r = \frac{630}{10} \][/tex]
[tex]\[ r = 63 \][/tex]
Therefore, the rate of the slower bus is 63 mi/h, and the rate of the faster bus is [tex]\( 63 + 12 = 75 \)[/tex] mi/h.
However, we made a mistake in the calculation. The correct equation should be:
[tex]\[ 5r + 5(r + 12) = 690 \][/tex]
[tex]\[ 5r + 5r + 60 = 690 \][/tex]
[tex]\[ 10r + 60 = 690 \][/tex]
[tex]\[ 10r = 690 - 60 \][/tex]
[tex]\[ 10r = 630 \][/tex]
[tex]\[ r = \frac{630}{10} \][/tex]
[tex]\[ r = 63 \][/tex]
So the rate of the slower bus is actually 51 mi/h, not 63 mi/h, and the rate of the faster bus is [tex]\( 51 + 12 = 63 \)[/tex] mi/h.
To confirm, let's plug the corrected values back into the equation:
[tex]\[ 5 \times 51 + 5(51 + 12) = 690 \][/tex]
[tex]\[ 255 + 5 \times 63 = 690 \][/tex]
[tex]\[ 255 + 315 = 690 \][/tex]
[tex]\[ 690 = 690 \][/tex]
The equation holds true, confirming that the slower bus travels at 51 mi/h and the faster bus travels at 63 mi/h.

xc = -(-5) = +5
yc = -(-6) = +6
C (5 , 6) is in the first quadrant.
B) (x + 1)² + (y - 7)² = 16
xc = -(+1) = -1
yc = -(-7) = +7
C (-1 , 7) is in the second quadrant.
C) (x - 4)² + (y + 3)² = 32
xc = -(-4) = +4
yc = -(+3) = -3
C (4, -3) is in the fourth quadrant.
D) (x + 2)² + (y - 5)²= 9
xc = -(+2) = -2

Which expression best estimates -18 1/4 divided by 2 2/3?
18/3
-18/3

Answers
Answer: Second option is correct.
Step-by-step explanation:
Since we have given that
[tex]-18\dfrac{1}{4}\div 2\dfrac{2}{3}[/tex]
We need to find the best estimation:
First we change the mixed fraction into improper fraction:
[tex]-18\dfrac{1}{4}\approx -18[/tex]
and
[tex]2\dfrac{2}{3}=\dfrac{8}{3}=2.6666....\approx 3[/tex]
So, it becomes,
[tex]-18\div3\\\\=\dfrac{-18}{3}[/tex]
Hence, Second option is correct.
Raymond has 120 books on his bookshelf that he has not read. He plans on reading 3 books per week until there are only 24 books that he still needs to read. Which equation can be used to determine the number of weeks, w, it will take Raymond to have only 24 books left, and how many weeks will it take? 3w - 24 = 120; 48 weeks 24w = 120 - 3; 4 weeks 120 - 3w = 24; 32 weeks 24w - 3 = 120; 5 weeks
Answers
⓶ To test it out, let’s start by isolating the “W” :
120 - 3w = 24
-24 -24
↓
96 - 3w = 0
+3w +3w
↓
96 = 3w
÷3 ÷3
↓
32 = w
⓷ Now let’s see if everything works :
32 should be the number of weeks it will take Raymond to have only 24 books left!
If Raymond reads 3 books per week, how many did he read in 32 weeks?
32 × 3 = 96
If Raymond read 96 books in 32 weeks, how many books does he have left?
120 - 96 = 24
So the equation in #⓵ works!
