The scale factor of the dilation = 2.5
The original dimensions of the rectangle:
Length = 32 ft
Width = 8 ft
The dimensions of the rectangle after dilation:
Length = 80 ft
Width = 20 ft
Dilation is a transformation where the dimensions of the figure is enlarged by multiplying with a number. This number multiplied with all dimensions of the original figure is called its scale factor.
So the new dimension of the figure will be scale factor times the original dimensions of the figure.
Thus the scale factor can be defined as the ratio of larger dimension to the smaller dimension of a figure.
Hence the scale factor used here is the ratio of new length to the original length or the ratio of new width to the original width of the rectangle.
That is, scale factor = 80/32 = 20/8 = 2.5

Carson works in a department store selling clothing. He makes a guaranteed salary of $450 per week, but is paid a commision on top of his base salary equal to 15% of his total sales for the week. How much would Carson make in a week in which he made $1575 in sales? How much would Carson make in a week if he made x dollars in sales?
HURRY PLEASEE!
Carson will make $686.25 in a week.
This problem can be solved by using percentage.
Percentage is the measure of a quantity with respect to its whole.
Given,
The total salary of Carson in a week is = $450
Also he gets a commission of 15% on making sales for a week.
In a week he makes a sales of $1575.
Commission for this week = 15% of 1575
= $236.25
Total salary for this week = 450+236.25
= $686.25
So, Carson will receive the above amount in a week as his salary.

The rate of change of what the cab company charges is; $3.3 per mile
What is the rate of change?The rate of change is simply the slope of the graph which is the change in y-values per change in corresponding x-values. Thus;
Rate of change here is;
Slope = (y₂ - y₁)/(x₂ - x₁)
We are told that the cab company charges a one time pick up fee of $2 for every ride as well as a $1.10 charge for each mile travelled.

The playing surfaces of two football tables are similar. The ratio of the corresponding side lengths is 10:7. What is the ratio of the areas?
The ratio of the areas is ?:?
The area ratio is 100:49.
The ratio of areas equals the ratio of squares of matching sides.
Let's put this fraction of comparable ratios into an equation and then input in our two known values to get our two unknown values:

Solve one half equals one fourth times the quantity y plus one eighth end quantity for y. y equals one half y equals three fourths y equals fifteen over eight y equals three halves
The value of y in the equation 1/2 = 1/4y + 1/8 when solved is: y = 3/2(three halves).
How to Solve an Equation?Solving an equation implies looking for the value of the variable that would make the equation true or balanced if we plug in the value of that variable into the equation.
To solve for the value of y in the given equation, 1/2 = 1/4y + 1/8, isolate the variable of equation, y, to one side.
1/2 = 1/4y + 1/8 [given]
1/2 - 1/8 = 1/4y + 1/8 - 1/8 [subtraction property of equality]
3/8 = 1/4y

What is the purpose of Fahrenheit?
Temperature measurements are made in Fahrenheit. It is based on the Fahrenheit scale, which was first put forth by physicist Daniel Gabriel Fahrenheit in the 1700s. According to the Fahrenheit scale, water has a boiling temperature of 212 degrees Fahrenheit, while ice melts at 32 degrees.Water freezes at 32 degrees Fahrenheit and boils at 212 degrees on the Fahrenheit temperature scale. The sign ° F is used to denote it.we have a value for F, and so we use that to find C. Insert F's value into the equation:
5 = 9/5 C + 32
Subtract 32 from both sides:
5 - 32 = 9/5 C + 32 - 32
-27 = 9/5 C

Which relation is also a function?
check the pic!!
PLEASE HELP!
Answer:
B
Step-by-step explanation:
I cannot see option D but regardless, C is a function for the following reasons
A function y = f(x) is a relationship in x such that f(x) has only 1 value for a value of x.
In A, we see that for x = -1 we have y = 2 and y = 4 for a single value of x = -1
That alone is sufficient to dismiss this as a function. If that wasn't bad enough you see that y = -3 and -4 for x = 2
In C we see the same problem
For x = 5 there are two value of y = -3 and -2
So we can disregard C
In B we can see a definite pattern
Between x = -2 and x = 0 we see that y increases by 1 unit for every increase of 1 unit in x. This is a linear relationship with a slope of + 1
Between x = 0 and x = +2, for every increase of 1 unit in the x-value, the y-value decreases by 1 unit. This is also a linear relationship but with a slope of -1
In particular this is what is known as a piecewise function. Its function expression is different for different intervals of x value
It can be expressed as follows
f(x) = x + 2 for -2 ≤ x ≤ 0
= -x + 2 for 0 ≤ x ≤ 2

how to graph y=3-4x
I have tried (0,3) (3,-9) and other possibilities, but they won't work
Answer:
This is a linear function and you have to rewrite the equation to the standard form y= mx+q, so y= -4x + 3 where -4 is m and tells you the slope of the function while 3 tells you where it intercepts the y axis. Now you have to write the points of the function taking some x values and obtaining the relative y. For example if x is 0 then y= 3-4(0) which is equal to 3. If x is 1 y is -1, if X is 2 then y is -5 and you continue like that until you want. However, to draw the line you could just stop to two points.

The solution for the system of linear equations y = 5 − x and 4x + 2y = 10 are x = 0 and y = 5
What are linear equations?Linear equations are equations that have constant average rates of change.
How to determine the solution to the system?A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
y = 5 − x
4x + 2y = 10
Substitute y = 5 − x in the equation 4x + 2y = 10
So, we have the following equation
4x + 2(5 - x) = 10
Open the brackets
4x + 10 - 2x = 10
Evaluate the like terms
2x = 0
Divide through by 0
So, we have
x = 0
Substitute x = 0 in y = 5 - x
y = 5 - 0
Evaluate the like terms
y = 5

The greatest extended dimension of a stationary item is typically believed to be its length. This is not always the case, as it may depend on the location of the item.

It makes it possible to carry out computations involving arbitrary large numbers by adhering to a set of straightforward processes. When the divisor contains only one digit, long division is nearly always avoided and instead, the condensed version, known as short division, is employed.

The arc corresponding to a central angle of 65 in a circle of radius 10 feet measures 11.34 feet.
What is Arc of circle?
The arc of circle is defined as the segment of the circumference of a circle.
Given that;
Central angle = 65°
Radius of a circle = 10 feet.
Now, To find arc of circle, we change measure of angle in radian as;
1 degree = π/180 radian
65 degree = 65 x π/180 radian
65 degree = 1.134 radian
Since, Arc = Angle x radius
Arc = 1.134 x 10
Arc = 11.34 feet.

What is rectangle ?
It is a common geometrical shape having 4 sides and four vertices and each side making 90 degree with the adjacent side.
Surface area of rectangle is given as :
s = 2(lb+bh+hl)
Volume of rectangle is given as :
V= lbh
Area of rectangle is given as ;
A = lb
If a rectangular photo measures 18cm by 7cm initially, the area of the photo before enlargement will be expressed as :
A1 = Length * breadth
A1 = 18 x 7
A1 = 126 cm²
If the photo is enlarged in the ratio 2:3 then increase/decrease in length and breadth will be :
2 : 3 = 2/3 = 0.66
This is 33% decrease of its dimensions’ measurements.
Length of the photo after decrement = 18 x 2/3 = 12 cm
breadth of the photo after decrement = 7 x 2/3 = 4.66 cm
Area of the decreased photo A2 = 12 x 4.66 cm² = 55.92 cm²
The ratio of the area of the original photo to the area of the enlarged photo = A1/A2 = 126 / 55.92
