A laundromat has a wash-and fold service for a monthly fee for $29.00. The laundromat will wash and fold clothes at $0.52 per pound for those customers with a laundry service. One customer paid $40.44 total for the month.
Which equation can be used to determine the pounds of laundry the customer brought in to be washed and folded that month?
a. 40.44 + 29.00 = 0.52x
b. 29.00 - 0.52x = 40.44
c. 0.52x + 40.44 = 29.00
d. 0.52x + 29.00 = 40.44
Answer:
Washing machines usually cost between $1.25 and $1.75 per load. Prices for dryers are a whole different ball of wax. Some dryers will charge you between $1 and $2 per load, while other dryers charge you by the minute — say, $0.25 for the first 15 minutes, then an additional $0.25 for every 10 minutes after that.Jul 17, 2019

Which one of these graphs does not illustrate a function? And why
Answer:
It would be Graph D
Step-by-step explanation:
It's graph D because according to the graph, it looks like the domain has 2 ranges since it made a vertical line. And as we know, vertical lines are not considered to be functional since a domain can't have more than one range.

Skate World offers birthday parties for a fee of $180 plus $2 per person. If you can spend no more than $210 on
your party, what is the maximum number of people who can attend?
Answer: 105
Step-by-step explanation: Skate World offers birthday parties for a fee of $180 plus $2 per person. If you can spend no more than $210 on
your party, what is the maximum number of people who (can) attend?
The keyword "can" is telling us to basically tell us to find how much people (can) attend. Not how much will attend.
210/2=105
A homeowner wishes to put a fence around a space in her yard to create a dog pen. The space that she wants to fence in is shown below where each unit on the
graph represents one foot,

How many feet of fencing will the homeowner need to build the dog pen?
38 + 4V2
54
52
38 + 1072
Answer: the answer is C 52
Step-by-step explanation:
The length of the fencing needed is given by the lengths of the lines
that goes around the space she wants to fence shown in the graph.
Correct response:
The amount of fencing the homeowner needs is; 38 + 10·√2Methods used to find the length of fencing neededThe coordinates of the vertices of the fenced area are presented as
follows;
A(-7, 7), B(4, 7), C(6, -7), and D(-7, -7)
Therefore, by finding the distance between the given points, we have;
Length of AB = 4 - (-7) = 11
Length of AD = 7 - (-7) = 14
Length of CD = 6 - (-7) = 13
Length of BC = √((6 - 4)² + (-7 - 7)²) = [tex]\sqrt{200}[/tex] = 10·√2
Length of fencing needed, L = AB + AD + CD + BC
Which gives;
L = 11 + 14 + 13 + 10·√2 = 38 + 10·√2
The length of fencing needed, L = 38 + 10·√2Learn more about the distance between points given the coordinates here:

A cone and a cylinder have the same radius and height. The volume of the cone is 100π (pi) cubic feet. What is the volume of the cylinder?
Answer:
The volume of the cylinder is [tex]300\pi[/tex] cubic feet.
Step-by-step explanation:
From Geometry we remember that volumes of a cone and a cylinder with the same radius ([tex]R[/tex]), measured in feet, and height ([tex]h[/tex]), measured in feet, are defined by the following equations:
Cone
[tex]V_{co} = \frac{1}{3}\pi\cdot R^{2}\cdot h[/tex] (1)
Cylinder
[tex]V_{cy} = \pi\cdot R^{2}\cdot h[/tex] (2)
The ratio of the volume of the cylinder to the volume of the cone is:
[tex]\frac{V_{cy}}{V_{co}} = 3[/tex] (3)
If we know that [tex]V_{co} = 100\pi\,ft^{3}[/tex], then the volume of the cylinder is:
[tex]V_{cy} = 3\cdot V_{co}[/tex]
[tex]V_{cy} = 300\pi\,ft^{3}[/tex]
The volume of the cylinder is [tex]300\pi[/tex] cubic feet.

A cricket ball is hit from a point A with velocity of (pi + qj)ms-1 at an angle theta above the
horizontal, i and j are the unit vectors horizontally and vertically upwards respectively. The point
A is 0.8 m vertically above the point 0, which is on horizontal ground.
The ball takes 4 seconds to travel from A to B, where B is on the ground and OB = 64 m, as
shown in the diagram. By modelling the motion of the ball as that of a particle moving freely under gravity,
a) find the value of p and the value of q
b) find the initial speed of the ball
c) find the exact value of tan theta
d )find the length of time for which the cricket ball is at least 5 m above the ground.
e )State an additional physical factor which may be taken into account in a refinement of the above model to make it more realistic.

Answer:
y = -⁹/₄x - 3Step-by-step explanation:
9x + 4y = -12 {subtract 9x from both sides}
4y = -9x - 12 {divide both sides by 4}
y = -⁹/₄x - 3

What is the equation of the line that passes through (1, 2) and (8,9) in slope-intercept form?
Answer:
The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: [tex]y = x+1[/tex]
Step-by-step explanation:
The slope-intercept form of line is given by the formula:
[tex]y = mx+b[/tex]
Here m is the slope and b is the y intercept
Given
[tex](x_1,y_1) = (1,2)\\(x_2,y_2) = (8,9)[/tex]
First of all, the slope has to be found
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{9-2}{8-1}\\m = 1[/tex]
Putting m=1 in the equation
[tex]y = x+b[/tex]
Putting the point (1,2) in the equation to find the value of b
[tex]2 = 1+b\\b = 2-1\\b = 1[/tex]
The equation is:
[tex]y = x+1[/tex]
Hence,
The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: [tex]y = x+1[/tex]
Which expression represents
the area of a rectangle with
sides measuring 7x4y2z units and
2xy5z14?
______________________________
1.) To solve this you must first know the formula for area of a rectangle:Area [tex]=\sf{H}[/tex] × [tex]\sf{W}[/tex]Area [tex]=7x^4y^2z[/tex] × [tex]2xy^5z^{14}[/tex]Note:
- It doesn't matter which measurement fills the height or width part in the formula.
Equation at the end of Step 1:
[tex]7x^4y^2z[/tex] × [tex]2xy^5z^{14}[/tex][tex]2xy^5z^{14}[/tex] × [tex]7x^4y^2z[/tex]2.) Add 4 and 1, (x powers:)[tex]x^4+x=x^5[/tex]Note:
- To multiply powers of the same base, you can add their exponents. So you just do [tex]4+1=5[/tex].
- When you have a plain variable like [tex]x[/tex], you can assume [tex]x=1[/tex].
Equation at the end of Step 2:
[tex]7x^5y^2z[/tex] × [tex]2y^5z^{14}[/tex]3.) Add 2 and 5, (y powers:)[tex]y^2+y^5=y^7[/tex]Note:
- To multiply powers of the same base, you can add their exponents. So you just do [tex]2+5=7[/tex].
Equation at the end of Step 3:
[tex]7x^5y^7z[/tex] × [tex]2z^{14}[/tex]4.) Add 1 and 14, (z powers:)[tex]z+z^{14}=z^{15}[/tex]Note:
- To multiply powers of the same base, you can add their exponents. So you just do [tex]1+14=15[/tex].
- When you have a plain variable like [tex]z[/tex], you can assume [tex]z=1[/tex].
Equation at the end of Step 4:
[tex]7x^5y^7z^{15}[/tex] × [tex]2[/tex]5.) Multiply 7 and 2:[tex]7[/tex] × [tex]2=14[/tex]Note:
- Since we combine all the powers and multiplied the bases, all you have to do is put it all together in 1 form like we were doing after we added powers in the earlier steps.
Equation at the end of All Steps:
