We can generate congruent shapes by combining the three types of transformations: rotations, reflections, and translations. Actually, using a combination of one or more of these three transformations, any pairs of congruent shapes can be matched to one another.
What are transformations?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
Given Data
We now understand that the size and shape of the figures are preserved during stiff transformations (reflections, translations, and rotations). Pre-image and image are always congruent with one another.
Series of transformation Matt can perform:
Reflection (Flip)
Because the equivalent points from the pre-image to the image remain at the same distance from the line of reflection, a reflection maintains its original shape.
Rotations as a Transformation of Congruence
A rotation is when a figure turns. Although the figure is the same size and shape, it appears to have fallen over. A clock is a fantastic example of a rotation in the real world. Every hour or every day, the connecting arms of a clock revolve around its central point. The degree of rotation is used to characterize a rotation; popular rotations include 90 degrees, 180 degrees, and 270 degrees. The figure returns to its original position after a full 360-degree spin. A rotation must additionally include the direction, either clockwise or counterclockwise. A rotation's degree amount and direction can be computed using this information.
Congruence transformation through translation
When we move an object or shape from one location to another without changing its size, shape, or orientation, we call that movement a translation. A translation, often known as a slide, involves moving each point on an object or shape by the same amount and in the same direction.

A personal trainer offers two different plans. Plan A costs $25 per session and Plan
B costs $50 per session. If the trainer coaches 18 sessions this week and earns $625
dollars, how many sessions of each type did he coach?
The personal trainer took 11 plan A and 7 plan B classes.
Let the number of sessions of plan A be x. So, the number of sessions of plan B be (18 - x). Now forming the equation as per the mentioned information.
25×x + 50 (18 - x) = 625
Performing multiplication on Left Hand Side of the equation
25x + 900 - 50x = 625
Rearranging the equation
900 - 625 = 50x - 25x
Performing subtraction on both the sides of the equation
275 = 25x
Shifting 25 to other side of equation
x = 275/25
Performing division to find the value of x
x = 11
Number of plan A classes = 11
Number of plan B classes = 18 - 11
Number of plan B classes = 7
Thus, the number of plan A classes is 11 and plan B classes is 7.

A cookie factory uses 1 1/3 bags of flour in each batch of cookies. The factory used 6 2/3 bags of flour yesterday. How many batches of cookies did the factory make
Answer: you can get the full fraction by multiplying 6x3 which is 18 so then you add 18 and 2 and you get 20 so now the fraction is 20/3
and you need 11/3 for a batch so now you have 1 whole batch and 9/3 so you just make the 11 a percentage which is 81%
so the answer is 1 whole batch and 81% of another

$_____
If a bicycle has a listed price of $522.95 before tax and the sales tax is 7.75%, then the total cost of the bicycle with sales tax included is $563.47
The listed price of bicycle = $522.95
The sales tax percentage = 7.75%
We know
C = p(t×p)
Where C is the total cost
p is the listed price
t is the sales tax percentage
Substitute the values in the equation
C = 522.95+((7.75/100)×522.95)
= 522.95+40.53
= $563.47

Write and inequality that will calculate the number of yards (y) you will
have to mow to get to at least the cost (C) of the car.
If the car cost a total of $4500 how many yards will you have to mow?
Step-by-step explanation:
You have found a used car and your parents have agreed to pay the first $750 for you. You have a summer job mowing yards for $25 per yard. Write and inequality that will calculate the number of yards (y) you will have to mow to get to at least the cost (C) of the car.
25y + 750 = C
If the car cost a total of $4500 how many yards will you have to mow?
25y + 750 = 4,500
subtract 750 from both sides:
25y + 750 - 750 = 4,500 - 750
25y = 3,750
divide both sides by 25:
25y/25 = 3,750/25
y = 150
Must mow 150 yards.
check:
25(150) + 750 = 4,500
3,750 + 750 = 4,500
4,500 = 4,500

The probability is 0.9204 that exactly 3 of them say job applicants should follow up within two weeks.
Binomial probability distribution
P(X = x) = [tex]C_{n,x}[/tex] . [tex]p^{x}[/tex] .[tex](1-p)^{n-x}[/tex]
[tex]C_{n,x}[/tex]= n!/ x!(n - x)!
The parameters are:
n is the number of trails.
x is the number of successes.
p is the probability of success on a single trial.
In this problem:
43% say job applicants should follow up within two weeks, thus p = 0.43
6 managers are selected, thus n= 6.
The probability that at least 3 of them say job applicants should follow up within two weeks is P(X≥ 3), which is given by:
P(X ≥3) = 1 -P(X < 3)
In which:
P(X < 3 ) = P(X = 0) + P(X = 1) + P(X = 2)
Then:
P(X = x) = [tex]C_{n,x}[/tex]. [tex]p^{x}[/tex]. [tex](1-p)^{n-x}[/tex]
P(X = 0) = [tex]C_{6,0}[/tex] [tex](0.43)^{0}[/tex]. [tex](0.57)^{6}[/tex] = 0.0342
P(X = 1) = [tex]C_{6,1}[/tex](0.43) . [tex](0.57)^{5}[/tex] = 0.0259
P(X = 2) = [tex]C_{6,2}[/tex](0.43)² [tex](0.57)^{4}[/tex] =0.0195
P(X<3) = P(X = 0) + P(X = 1) + P(X =2) = 0.0342 + 0.0259 + 0.0195
= 0.0796
P(X≥3) = 1 - P(X<3) = 1- 0.0796 = 0.9204

If the length of a side of cube is "s", then total edge length (E = 12s), total surface area (A = 6s²) and Volume (V = s³).
As per the question statement, the length of a side of cube is "s".
We are required to write down the equations for total edge length "E", total surface area "A" and Volume "V" of the cube with respect to "s".
To solve this question, we need to know a couple of basic structural properties of a cube, that is,
There are 12 edges in a cube, all of equal length,
And, there are 6 faces in a cube, all of equal surface area.
[A reference image is attached hereby for better understanding;
The 12 edges of the cube are: AB, BC, CD, AD, CG, DH, BF, AE, EF, FG, GH and EH,
And, the 6 Faces of the cube are: ABCD, ABEF, CDGH, BCFG, ADEH and EFGH]
Therefore, total edge length (E) = (12 * s) = 12s,
Or, (E = 12s)
Total surface area (A) = [6 * (s)²] = 6s²,
Or, (A = 6s²)
[Since, area of a square of edge length "s" = s², and every face of a cube is a square]
Finally, Volume (V) of the cube = [s * s * s] = s³,
Or, (V = s³).

Alexandria a car dealer, earns 1/25 commission of her luxury vehicle sales. Last year, her sales were $480,000. What was the total dollar amount of her commission last year?
The total dollar amount of her commission last year equals to $19,200.
What is a sales commission?This refers to the percentage of the value of a sale that a sales associate or representative may earn.
To start, we must analyze the data we have. Given that Alexandria's total sales were $ 480000, and the commission received is 1/25 of that sales.
The commission earned from the sales:

How to solve a quadratic equation by substitution?
The equation is first transformed into a more familiar form. Replace the substitutions with the original variables after factoring the problem. The difference of squares equation is used to finish the factorization and locate the answers for x.
Given, the equation for solving is: (x + 2)² - 2(x + 2) - 15 = 0 --(i)
Let in the equation, y = x + 2 --(ii)
Equating (i) and (ii), we get:

What is the unit price of apples at store C? How did you use the graph to find the unit price? (3 points) 4. Which store has the lowest unit price for apples? (3 points)
1. Store A's unit price = $4 per pound
2. Store B's unit price = $2 per pound.
3. Store C's unit price = $3 per pound.
4. Store B's unit price is the lowest.
How to Find the Unit Rate of a Relationship?The unit rate of the relationship between variables x and y, is given as:
Unit rate, m = y/x.
In a given equation, y = mx, the value of m represents the unit rate of the relationship.
In the scenario given, y represents cost in dollars while x represents the number of pounds of apples.
1. The unit rate = unit price of apples. For store A, we are given 3 pounds of apples will cost $12, therefore:
Unit price = y/x = 12/3
Unit price = $4 per pound
2. For store B, the "2" in the equation, y = 2x, represents the unit price.
Unit price for store B = $2 per pound.
3. Using one point on the graph for Store C, say, (2, 6):
Unit price = y/x = 6/2
Unit price = $3 per pound.
4. The lowest unit price is $2 per pound, therefore, Store B has the lowest unit price for apples.
