One interior angle of a regular octagon is
Answer:
135 degreesTo find the measure of the angles, we know that the sum of all the angles is 1080 degrees (from above)... And there are eight angles... So, the measure of the interior angle of a regular octagon is 135 degrees.The General Rule
Shape Sides Each Angle
Octagon 8 135°
Nonagon 9 140°
... ... ...
Any Polygon n (n−2) × 180° / n
Which equation below and solution for x does the model represent?
A) 2x + 2x = 85, x=42.50
B) 4 + x = 85, x=21.00
C) x + x + x = 85, x=21.00
D) 4x = 85, x=21.25
Answer:
Option D
Step-by-step explanation:
Cost of 4 shirts all together = $85
Model given in the picture attached will be,
x + x + x + x = 85
4x = 85
[tex]\frac{4x}{4}=\frac{85}{4}[/tex]
x = 21.25
Therefore, Option D will be the correct option.

A. THERERREREEHUGGG HHHU
Step-by-step explanation:
Length = 5x +4
Breadth = 4x-4
Perimeter = 2(L+B)
Perimeter :
[tex]2(5x + 4 + (4x - 4)) \\ 2(5x + 4 + 4x - 4) \\ 2(5x + 4x + 4 - 4) \\ 2(9x) = 2 \times 9x[/tex]
[tex] = 18x[/tex]

Step-by-step explanation:
Can someone explain Slope to me? I literally have no idea what is from my teacher or from Aleks. I don't get what y1 and y2 are and i don't get what rise or run is. I have no idea how to get slope (brainliest for whoever explains a function too)
Yeah, I know Alex sucks. SO slope is the change in Y over x. So to find slope for ex. is lets use points (8,4) and (6,5) the equation to find slope is Y2-Y1 over X2-X1 or Y2-Y1 / X2-X1 and that basically the y's on the points you have. In this case it will be 4 and 5 since y always comes second or after the x. What I like to do is this X1(8), Y1(4) and X2(6), Y2(5). After you have that set up you just put them in the equation it will be 5-4/6-8 which is -1/2 use calculator. So Y is the y-axis and X is the x-axis.
Function is when every input(x) has only one output(y) . For example if we have the table
X,1 , 4 , 5, 9, 10 this is not a function because the -3 has both 9 and 10 for an output.
Y,2, 6 ,6, -3 , -3
A function will look more like this
1 2 3 4 5 6
2 4 6 8 10 12 every output has only one input
I recommend to watch Brian McLogan on youtu he can really help. Just search anything then his name. Or even Function then his name he explains it really well.

7x-7=3x-23. can u show the steps
Answer: ight bet i gotchu its x=−4
Step-by-step explanation:
Let's solve your equation step-by-step.
7x−7=3x−23
Step 1: Subtract 3x from both sides.
7x−7−3x=3x−23−3x
4x−7=−23
Step 2: Add 7 to both sides.
4x−7+7=−23+7
4x=−16
Step 3: Divide both sides by 4.
4x/4=-16/4

Identify the graphed linear equation?
Answer:
C
Step-by-step explanation:
The first thing I notice is the slope, which is going down, which means this is for sure a negative slope. So any slopes that just include 5 is now crossed off. And since the formula goes like y=mx+b, I believe the answer would be C, because it actually follows the formula as it should. If I'm wrong, pick D for sure.

School guidelines require that there must be at least 2 chaperones for every 25 students going on a school trip. How many chaperones must there be for 82 students? A. 6 chaperones B. 41 chaperones C. 7chaperones D 3 chaperones
Answer:
A. 6 chaperones
Step-by-step explanation:
Since it's 2 chaperones per 25 students you would need to see how many times 25 can fit into 82
82/25 = 3.28
You can round that number to 3
Then you'll multiply 3 by 2 to get your number of chaperones for the school trip
3 x 2 = 6
There's still students left but not enough for there to be another chaperone so the answer is 6
In a family of 11, what is the probability that there will be more boys than girls
Answer:
P(all female)= 1/2 x 1/2 x 1/2 = 1/8
P(all male ) = 1/2 x 1/2 x 1/2 = 1/8
P(all one gender) = P(all female) + P(all male) = 1/8 + 1/8 = 1/4
What is the probability that a three-child family is two girls and one boy?
Each possible birth order has P=1/8. That is, P(G,G,B)=P(G,B,G)=P(B,G,G)=1/8.
So, P(2G,1B)= 3/8 and P(1G,2B)= 3/8.
This allows us to write the overall gender probability distribution for families of three children as follows:
1/8 will be three girls
3/8 will be two girls and one boy
3/8 will be one girl and two boys
1/8 will be three boys
Adding it all up, we have 1/8 + 3/8 + 3/8 + 1/8 = 1 (100%)

options: given, vertical angles, corresponding angles, and transitive
Answer:
1. Given
2. Vertical angles
3. Transitive
4. Corresponding Angles
Step-by-step explanation:
1. Number one is given because it is the statement that is given
2. Number two is vertical angles because they are two opposite angles that are formed by the same lines. The statement also says they are congruent, which is true of vertical angles.
3. From the given answers 3 must be transitive because <2=<4 and <2=<6. Although alternate interior angles is also an appropriate answer.
4. Number four must be corresponding because they are on the same side of the intersection of the lines, so they are both in the top right. Also, the statement says they are congruent which is true of corresponding angles.

Step-by-step explanation:
There are some pencils and erasers in a
box. If there are 12 pencils and the ratio
of pencils to erasers is 3:2, how many
erasers are in the box?
Answer:
There are 8 erasers in the box
Step-by-step explanation:
given that the Ratio of pencils to erasers is 3:2
No matter how many pencils and erasers are there the ratio will simplify to the given ratio.
Let x be the number of erasers when there are 12 pencils
The ratio of 12 pencils to x erasers will be same 3:2
Putting it mathematically
[tex]\frac{pencils}{erasers} = \frac{pencils}{erasers}\\\frac{12}{x} = \frac{3}{2}\\12 * 2 = 3x\\3x = 24\\\frac{3x}{3} = \frac{24}{3}\\x = 8[/tex]
Hence,
There are 8 erasers in the box

What is the slope in the equation? y + 2 = 5(x - 1)
Answer:
m=5
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
Let's write the equation in the slope-intercept form by solving for y.
y + 2 = 5(x - 1)
y = 5x - 5 - 2
y = 5x - 7
Answer: The slope is 5
