How to Interpret Transformation of Objects?
In transformations, there are different types such as dilation, reflection, translation, rotation, e.t.c
1) Dilation of a quadrilateral by a scale factor of 2;
When we dilate by a scale factor of 2, it simply means we are enlarging the side lengths by a scale factor of 2. Thus, the side lengths will increase but angles remain the same.
2) Translation of a rhombus 3 units to the right and then a reflection across the x-axis;
When we translate an object, it means we just move it from one point to the other and this means that the length and angles do not change, Similarly, reflection is just a mirror image and it also means that the length and angles do not change.
3) Translation of a triangle 2 units to the left and then a dilation by a scale factor of 5 about the origin;
This will end up changing the side lengths but not the angles.

What are fractions?Fractions are used to depict the components of a whole or group of items. Two components make up a fraction. The numerator is the number that appears at the top of the line. It specifies how many identically sized pieces of the entire event or collection were collected. The denominator is the quantity listed below the line. The total number of identical objects in a collection or the total number of equal sections that the whole is divided into are both displayed. A fraction can be expressed in one of three different ways: as a fraction, a percentage, or a decimal. The first and most popular way to express a fraction is in the form of the letter ab. Here, a and b are referred to as the numerator and denominator, respectively.
Let the number of pieces = x
The length of the wire = 5/8 inches
The length of one piece of wire = 1/4 inch
According to the question,
1/4 x = 5/8
So, x = 5/8 × 4
x = 20/ 8
x = 5/2
x = 2.5 inch

Mean for the girls is 137.6% of the mean for the boys.
What is Mean?
Suppose, there is a data and the average of the data has to be calculated. Mean is used to find the average of the data.

Given:
The local rate for electrical service is 6 cents per kilowatt-hour.
We need to know how much money would be saved in a year by using a dishwasher 4times per week rather than 6 times per week
From the table:
The cost of using a dishwasher 4 times per week = $29
The cost of using a dishwasher 6 times per week = $44
So, the saving will be = 44 - 29 = 15

The total number of participants who went on the seventh-grade field trip to the Pink Palace consisted of all of the seventh-grade students and 13 adult chaperones. Four-ninth of the total participants rode a large bus, and the rest rode a smaller bus. If 156 people rode the larger bus, how many students went on the field trip?
Answers
338 students went on the field trip.
Given:
Four-ninth of the total participants rode a large bus, and the rest rode a smaller bus.
156 people rode the larger bus.
Let x be the total participants.
4/9 x = 156
multiply by 9 on both sides
4*9/9 x = 156*9
4x = 156*9
4x = 1404
divide by 4 on both sides
4x/4 = 1404/4
x = 1404/4
x = 351.
number of students = total participants - adult chaperones.
= 351 -13
= 338 students
Therefore 338 students went on the field trip.

To solve for the value of b, we will have:

Working together, two secretaries can stuff the envelopes for a political fund-raising letter in 4 hours. Working alone, it takes the slower worker 15 hours longer to do the job than the faster worker. How long does it take each to do the job alone?.
Answers
The slower worker takes 20 hours and faster worker takes 5 hours to complete the job .
In the question,
it is given that ,
two secretaries stuff the envelopes for a political fund-raising letter in 4 hours .
let the time taken by fast worker to complete the job be x hours .
the slower worker takes 15 hours longer to do the job than faster worker
So , the time taken by slow workers to complete the job will be (x+15) hours .
the amount of work done by faster worker in 1 day = 1/x
the amount of work done by slower worker in 1 day = 1/(x+15)
total work done by both in 1 day = 1/x + 1/(x+15)
their combined 1 day work will be equal to 1/4 .
The equation representing is
1/x + 1/(x+15) = 1/4
(x+15+x)/(x²+15x) = 1/4
(2x+15)/(x²+15x) = 1/4
4(2x+15) = x²+15x
8x + 60 = x²+15x
x² + 15x - 8x - 60 = 0
x² + 15x - 8x - 60 = 0
x² + 7x - 60 = 0
x² + 12x - 5x - 60 = 0
x(x+12) -5(x+12) = 0
(x-5)(x+12)=0
we get x -5 = 0 or x+12=0
x = 5 or x = -12 .
the time cannot be in negative ,
So , fast worker to complete the job in = 5 hours
slow worker to complete the job in = 20 hours
Therefore , The slower worker takes 20 hours and faster worker takes 5 hours to complete the job .

What is system of equation?A group of equations involving one or more variables is known as a system of equations. The variable mappings that satisfy each component equation, or the points where all of these equations intersect, are the solutions to systems of equations. In order for one term to have equal and opposite coefficients in the two equations, multiply one or both equations by an integer. The equations are combined to form a single equation with a single variable. Do the variable's solution. Reintroduce the variable into the equation and then find the value of the other variable. Systems of linear equations in two variables can be solved in one of three ways: by graphing; by the substitution method; or by the elimination method.
Here,
Let x be the plate of 7 inch and y be the plate of 12 inch.
x+y=15
The total of diameter for both the plate is 145 inches.

Answers
Given:
When the price of admission was $19, the attendance was about 1550 customers per week
And, when the price of admission was dropped to $16,
attendance increased to about 2350 per week
Let the attendance = A
And the price = p
The linear equation will be A = mp + b
Where (m) is the slope and (b) is the y-intercept
So,
When p = 19, A = 1550

Answers
The linear equations of the graph are y = 2/3x + 1. Option D.
Solution:
Let's find the slope of the graph using the coordinates (0, 1) (-3, -1)
m = y₂ - y₁ / x₂ - x₁
m = -1 - 1 / -3 - 0
m = -2/-3
m = 2/3
Using the slope-intercept form,
y = MX + c

m = slope
c = y-intercept(This is when x = 0)
Therefore,
c = 1
Finally, the equation will be y = 2/3 x + 1.
