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.

Rafael is fertilizing his garden. The garden is in the shape of a rectangle. Its length is 16 feet and its width is 13 feet. Suppose each bag of fertilizer covers 26 square feet. How many bags will he need to cover the garden?
step 1
Find the area of the garden
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
x ----> number of bags
x=(1/26)*208
x=8 bags
therefore
the answer is 8 bags(Worksheet typo.. Use this question) On the same map, the dining hall is located at (-12, 6) and the stables are located at (20, 6). How far apart is the dining hall from the stables? (Just type in the number)
If the dining hall is located at (-12,6) and the stables are located at (20,6), then the dining hall is 32 units apart from the stables
The location of the dining hall = (-12,6)
The location of the stables = (20,6)
The distance between the two points d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Where d is the distance between the two points
[tex](x_1,y_1)[/tex] is the coordinates of the first point
[tex](x_2,y_2)[/tex] is the coordinates of the second point
Substitute the values in the equation
d = [tex]\sqrt{20-(12))^2+(6-6)^2}[/tex]
= [tex]\sqrt{1024}[/tex]
= 32 units
Hence, if the dining hall is located at (-12,6) and the stables are located at (20,6), then the dining hall is 32 units apart from the stables

Based on the reflexive property of congruency, the other pair of sides that we know are congruent is: 1. QS = SQ.
What is the Reflexive Property of Congruency?The reflexive property of congruency states that a line will always be a congruent to itself. This means it will always be equal in measure to itself.
In the diagram given showing triangle QSP and triangle SQR, we are given that sides PQ and RS are congruent so also are angles PQS and RSQ.
However, we can also see that both triangles share a common side, side QS. Therefore, side QS is congruent to side SQ by the reflexive property of congruency.

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

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

a florist shop gets an average of 18 phone orders in a 2 hour time period. in order to find the probability that the florist shop will get at most 4 phone orders in a 30 minute period using the poisson distribution, what is the average number of phone orders per 30 minutes?
If the probability that the florist shop will get at most 4 phone orders in a 30 minute period using the Poisson distribution, the average number of phone orders per 30 minutes is 5.
How to find the average number of phone order?Given data:
Average 18 phone order in 2 hour
4 phone orders in a 30 minute
Let x represent the average number of phone orders in 30 minutes.
Hence
then x30=18/120
Solving for x
x =18(30)/120
x = 540 / 120
x = 4.5
x = 5 (Approximately)

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:

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)

The output of the program code block given will be two.
What is Python Programming language?Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation.
Given is the following code structure -
x = 6 % 2
if x == 1:
print("ONE")
else:
print("TWO")
If we dry run the program, we can write -
x = 6 % 2
x = 0
Now, x is not equal to 1, therefore, it will print two.
Therefore, the output of the program code block given above will be two.
