The proofreading rate will be ( 7.5 pages/ hour) and the cost per hour will be $20.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Karyn proofreads 15 pages in 2 hours for $40. The rate will be calculated as:-
Rate of reading = ( 15 / 2 )
Rate of reading = ( 7.5 ) pages per hour
The cost will be calculated as:-
For 2 hours = $40
For 1 hour = ( 40 / 2 )
For 1 hour = $20
Therefore, the proofreading rate will be ( 7.5 pages/ hour) and the cost per hour will be $20.

Graph the dilated image of triangle XYZ using a scale factor of 1.5 and (0,0) as the center of dilation
Please find attached the dilated image of triangle ΔXYZ obtained by using a scale factor of 1.5, with the center of dilation at (0, 0), giving the coordinates of the vertices at the points X'(-6, 3), Y'(9, 0) and Z'(-3, -6).
What is a dilation transformation?A dilation transformation is one in which the lengths of a figure are scaled up or down.
From a similar question online, we have:
The vertices of the triangle ΔXYZ are: X(-4, 2), Y(6, 0), and Z(-2, -4)
The given center of dilation is (0, 0)
The scale factor of the dilation is 1.5
The coordinates of the points on the image following a dilation of the point (x, y) by a scale factor of k about the origin is given by the formula:
(x, y) [tex]\underrightarrow{R_k}[/tex] (k·x, k·y)
Therefore, the coordinates of the vertices of the image of the triangle ΔXYZ following a dilation by a scale factor of 1.5 are:
X(-4, 2) [tex]\underrightarrow{R_k}[/tex] X'(1.5×(-4), 1.5×2) = X'(-6, 3)
Y(6, 0) [tex]\underrightarrow{R_k}[/tex] Y'(1.5×6, 1.5×0) = Y'(9, 0)
Z(-2, -4) [tex]\underrightarrow{R_k}[/tex] (1.5×(-2), 1.5×(-4)) = (-3, -6)

$134 is the amount paid by grandparents every month.
What is the percentage?Percentage as the name suggests is a ratio of some particles to 100. In order to get the value of the required amount one has to divide the value by 100.
It is given that the tuition fee is $180 per week = $720 per month
It is also provided that she receives an honour rule of $50 per month.
So, her fees per month is $720- $50= $670.
It is given that 20% of the fees is paid by grandparents.
So, percentage share = 20% of $670 =20/100 x $ 670 = $134

Remember that the area of a rectangle is equal to
A=L*W
we have
L=16 ft
W=13 ft
substitute
A=16*13
A=208 ft^2
step 2
we know that
each bag of fertilizer covers 26 square feet
so
Applying proportion
1/26=x/208
solve for x

What is a cone?
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex.
We are given that radius of the cone as 5yd and slant height as 13yd
We first find the height using pythagoras theorem
Let height be h
by Pythagoras theorem we have
[tex]r^{2}+h^{2}=13^2\\ 5^2+h^2=169\\ h^2=144\\h=12[/tex]
Height of the cone is 12yds
Now volume of the cone is given by
[tex]V=[/tex]π[tex]r^{2}\frac{h}{3}[/tex]
Substituting the values in the equation we get
[tex]V=100[/tex]π yd^3
Now we find the surface area
The formula for surface area is
[tex]A=r(r+\sqrt{r^2+h^2} )[/tex]π
Substituting the values in the equation we get
[tex]A=90[/tex]π yd^2
Hence the surface area of the cone is 90π yd^2

Answer: (y-(-43))=-7(x-6) and y=-7x-1
Step-by-step explanation:
1) Pick two points. I'll choose (3,-22) and (6,-43)
2) Next set it up in a rise-over-run function
-43 - (-22)
-------------
6 - 3
3) Solve
-21/3
-7
The slope is -7
4) Find the starting value.
You can do this by substituting two points in a slope-intercept equation(y=mx+b)
y=-7x+b
-22=-7(3)+b
-22= -21+b
-1=b
The starting value is -1.
5) Slope intercept form
We can put all the info together to find that the slope-intercept is:
y=-7x-1
6) Point-slope form:
Point slope form equation is this: y-y1=m(x-x1)
y1 and x1 are one of the points while keeping x and y as variables
So our final equation is (y-(-43))=-7(x-6)

A linear equation with one variable is one that contains just one variable.

One such linear equation in one variable is 9x + 78 = 18.275000 = 3001 - ( 1 + 0.38/12)⁻¹²t/0.038/12
275000 = 3001 - ( 1 + 0.38/12)⁻¹²t/0.0025
275000 * 0.0025 = 3001 - ( 1 + 0.38/12)⁻¹²t
68.75 = 3001 - ( 1 + 0.38/12)⁻¹²t
3001 - 68.75 = ( 1 + 0.38/12)⁻¹²t

The value of the Constant of Proportionality will be $2.19.
In the given question, it is stated that 3 pounds of grapes cost $6.57. We have to calculate and find out the Constant of Proportionality.
The constant of Proportionality is a constant term in the equation that does not vary and has a fixed value that represents a certain quantity in a given situation.
Here, we know that 3pounds cost $6.57. Taking:
y = Total Cost
x = Number of Pounds
c = Constant of Proportionality
We get the equation to represent the Total cost with respect to the number of pounds where c will be the proportionality constant which defines the unit price of a pound. The equation will be:
=> y = c*x
=> 6.57 = 3c
=> c = 2.19

Answer:the 2nd choice
Step-by-step explanation:
The tuition costs, C, for a local community college are modeled by C(h) = 250 + 200h, where h represents the number of credit hours taken. The local state university has tuition costs, S, modeled by the function S(h) = 300 + 180h.
How many credit hours will a student have to take for the two tuition costs to be equal? Round the answer to the nearest tenth of an hour.
250 + 200h = 300 + 180h
250 + 200h = 300 + 180h
− 180h − 180h
250 + 20h = 300
The credit hours that a student has to take for the two tuition costs to be equal is A. 250 + 200h = 300 + 180h
How to illustrate the information?From the information, the tuition costs, C, for a local community college are modeled by C(h) = 250 + 200h
h = the number of credit hours taken.
The local state university has tuition costs, S, modeled by the function S(h) = 300 + 180h.
Therefore, the credit hours that a student have to take for the two tuition costs to be equal will be:
250 + 200h = 300 + 180h
200h - 180h = 300 - 250
20h = 250
h = 250/20
