Polygon LMNOP was transformed to create polygon L'M'N'O'P'.2 pentagons have identical side lengths and angle measures. The points are labeled with the same letters.
Which angle corresponds to AngleN?
Angle
Angle
Angle
Angle
The Angle that would correspond to Angle N after the transformation is; Angle N'
How to Interpret Transformations?
A polygon is defined as a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.
In the transformation of LMNOP to create polygon L'M'N'O'P', we have that;
L corresponds to L'
M corresponds to M'
N corresponds to N'
O corresponds to O'
P corresponds to P'
Thus, we can conclude that Angle N would correspond to Angle N'

The sequence of transformations that can be performed on quadrilateral ABCD to show that it is congruent to quadrilateral
The sequence of transformations that can be performed on quadrilateral ABCD to show that it is congruent to quadrilateral is 90° counterclockwise rotation about point A followed by the reflection across y axis and a translation 20 units down.
What is transformation?It should be noted that a transformation simply illustrates the change in shape.
In this case, the sequence of transformations that can be performed on quadrilateral ABCD to show that it is congruent to quadrilateral is 90° counterclockwise rotation about point A.

How many points? Help me please:)
Answer:
187 Points
Step-by-step explanation:
Total ratio units = 17 + 14 = 31 units
Total they scored = 341 points
Therefore total units = 31 = 341 points
31 units = 341 points
1 unit = (341/31) points
1 unit = 11 points
Nina scored 17 units of the total points
17 units = (17 x 11) points

The value of the relative frequency distribution of the first interval, having a frequency of 14, and the total frequency given is 40, is 0.35.
In a Relative Frequency Distribution, we list how often a data value appears and scale it using the total frequency.
The sum of Relative Frequencies adds to 1.
In the question, we are informed that the first interval has a frequency of 14.
This implies that the data appears 14 times in the first interval.
Also, we are told that the total frequency is 40.
Thus, the relative frequency can be calculated as the ratio of the frequency of the interval to the total frequency.
Therefore, Relative frequency = 14/40 = 0.35.
Thus, the value of the relative frequency distribution of the first interval, having a frequency of 14, and the total frequency given is 40, is 0.35.

much must Tien pay in total for the day
The addition is one of the four fundamental mathematical operations. The total wage that Titan needs to pay is $414.63.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Given Each employee is paid a minimum wage of $8/hour for an 8-hour day. They are also paid a commission of 12% on all sales they make. Therefore, the expression for the minimum wage can be written as,
Pay for an employee = (8x8) + 0.12(Sales made) = $64 + 0.12(Sales made)
Pay of the first employee = $64 + 0.12($785.96) = $158.32
Pay of the second employee = $64 + 0.12($452.87) = $118.34
Pay of the third employee = $64 + 0.12($616.42) = $137.97
The total wage that is needed to be paid for the day i,
Total = $158.32 + $118.34 + $137.97 = $414.63

7 + 15 + 23 + ... + 767 + 775 + 783We can notice that:
Subsequence terms have the difference of 8,The first term is 7,The last term is 783.Since the difference between subsequence terms is same, the terms form an arithmetic progression.
Use the nth term equation to find the number of terms:
aₙ = a₁ + (n - 1)dUse the given values and find n:
783 = 7 + (n - 1)*88(n - 1) = 776n - 1 = 776/8n - 1 = 97n = 98Now use the equation for sum of the first n terms of AP:

Point X is the incenter of ΔABC.
Triangle A B C has point X as its incenter. Lines are drawn from the points of the triangle to point X. Lines are drawn from point X to the sides of the triangle to form right angles. Line segments X F, X G, and X E are formed.

The measures of GX = 13
The measures of [tex]\angle ABX=22^0[/tex]
EX = 4z + 1 and XF = 2z + 7
Take EX and XF equal time each other and then solve for z and then you will get GX because EX = XF = GX are congruent.
EX = XF
What is congruent?
Two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
4z + 1 = 2z + 7
2z = 6
z = 3
As, EX = XF = GX
EX = 4(3) + 1
EX = 13

Use the information in this table(in the attachment) to help you answer the questions. Remember, you have a budget of $20,000 for the car.
1. What add-on options do you want in your car?
Sun-roof, and Keyless entry
2. Write an inequality to model purchasing a car from Dealership A with the desired add-on options and staying within your budget. Use x to represent the base price of the car. (Assume that only the base price of the car is taxed to simplify the problem.)
3. Solve for x. Explain in words what the solution to the inequality means.
4. Graph the possible base price values that are included in the solution. Please upload an image of your graph.
5. Complete 2–4 for Dealership B using the same add-on options.
Will you buy from Dealership A or from Dealership B? Why?
The best buy is from dealership B because dealership B has a lesser base price
The add-on optionsFor the purpose of this exercise, the add-on options to select are:
SunroofKeyless entryDealership AThe total amount of the add-on options is:
Total = $500 + $1500
Total = $2000
The inequality
This is represented using:
Base price * (1 + Tax) + Fees + Add-on total ≤ 20000
So, we have:
(1 + 6.75%) * x + 751.56 + 2000 ≤ 20000
Solve for x
We have:
(1 + 6.75%) * x + 751.56 + 2000 ≤ 20000
Evaluate the like terms
(1 + 6.75%) * x ≤ 17248.44
Divide both sides by (1 + 6.75%)
x ≤ 16157.79
The solution means that the base price of the car cannot exceed $16157.78 for dealership A
The graph of the possible base price
See attachment
Dealership BThe total amount of the add-on options is:
Total = $750 + $1000
Total = $1750
The inequality
This is represented using:
Base price * (1 + Tax) + Fees + Add-on total ≤ 20000
So, we have:
(1 + 6.75%) * x + 1524.72 + 1750 ≤ 20000
Solve for x
We have:
(1 + 6.75%) * x + 1524.72 + 1750 ≤ 20000
Evaluate the like terms
(1 + 6.75%) * x ≤ 16725.28
Divide both sides by (1 + 6.75%)
x ≤ 15667.71

8x: The x in 8x signifies the amount of books you can buy. So let's say you want to buy 4 books then x would be 4 and 8x would be equivalent to 42.
55y: The y in 55y signifies the amount of video games you can buy. So let's say you want to buy 2 video games then y would be 2 and 55y would be equivalent to 110.
≤: We're using this sign because you can spend a maximum of 184 dollars. Meaning that the amount you spend (which is the 8x+55y) has to be less than or equal to 184 dollars.
184: The amount of money you are able to spend total.
