The mark-up for the playground slides is 170%. The mark-up refers to the price added to the cost to find out the selling price of a product.
Mark-up is the difference between the selling price and cost price of a product.It is usually represented as a percentage, the mark-up percentage is calculated over the cost of the product. In other words we can say that mark-up is the profit gained from selling a particular product. Here it is said that the cost of a playground slide is $290 and the selling price of the playground slide is $783. We need to find the mark-up percentage of the playground slide.
Mark-up %=[tex]\frac{selling price-cost}{cost}[/tex]×100=[tex]\frac{783-290}{290}[/tex]x100=[tex]\frac{493}{290}[/tex]x100=170%
Therefore the mark-up percentage of the playground slide is 170%.

In the figure, the angle x° is an alternate angle with angle 54° so the measure of angle x° is 54°.
We have,
From the figure,
Line m and line n are parallel.
Line t is the transversal line.
Now,
Alternate angles are a pair of angles that are formed when a transversal (a line that crosses two other lines) intersects two parallel lines.
When this happens, the alternate angles are on opposite sides of the transversal and are congruent, which means they have the same measure.
Angle 54° and angle x° are alternate angles.
Alternate angles are equal.
So,
x° = 54°
Thus,

Step-by-step explanation:
There's 3 lines in the middle before it's the number 1, if u count 1 into the lines then there's 4, 1 divided by 4 is 0.25 or 1/4, so each small line is going up or down by 1/4. So it's 0 -> 1/4 -> 2/4 -> 3/4 which is A -> 4/4 which is 1

The Roster form of { 8,12,16 } is {X;X=4k ,k ∈ (2,34)}
Roster form:
A set's roster notation is a straightforward mathematical representation of the set. The elements (or members) of a set are listed in a row inside the curly brackets in the roster form. If the set contains more than one element, each pair of elements is separated by a comma symbol. Because the enumeration is done one by one, the roster form is also known as the enumeration notation.
Given a set in a set builder form i.e.{ 8,12,16 } and asked to convert into Roster form
Roster form of { 8,12,16 } ={X;X=4k, k ∈ (2,34)}

The graph below shows the solution to a system of inequalities: Solid line joining ordered pairs 0, 3.75 and 15, 0. Shade the portion of the graph above the line in the first and second quadrant Which of the following inequalities is modeled by the graph? (5 points) Group of answer choices x + 4y ≥ 15; y ≥ 0 x − 4y ≥ 15; y ≥ 0 x + 4y ≤ 15; y ≥ 0 −x − 4y ≥ 15; y ≥ 0
Answer:
x + 4y ≥ 15; y ≥ 0
Step-by-step explanation:
The solid line signifies it is a ≤ or ≥.
The equation of the line joining 0, 3.75 and 15, 0 is gotten using the formula:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\Substituting:\\\\y-3.75=\frac{0-3.75}{15-0}(x-0)\\\\ y-3.75=-\frac{1}{4}x\\\\y=-\frac{1}{4}x+3.75\\\\4y=-x+15\\\\4y+x=15[/tex]
Since the first and second quadrant are shaded, this represents y ≥ 0.
Also, above the solid line of 4y + x = 15 is shaded, this represents 4y + x ≥ 15.
Hence the inequality modeled is x + 4y ≥ 15; y ≥ 0

Step-by-step explanation:
f(x) = 2x³ + 7x² - 4x - 5
g(x) = 3x - 2
Find (f - g)(x).
The value of (f-g)(x) is 2x³ + 7x²-7x-3.
As we know that, the composition of functions is the criteria of combining two or more functions into a single function. A function represents some work. The combination of two or more function always results in a new function.
Given that, f(x) = 2x³ + 7x² - 4x - 5 and g(x) = 3x - 2 and we have to calculate the value of (f - g)(x).
Suppose h(x) = (f - g)(x)
Now, we simply have to solve (f - g)(x), let's proceed to solve
= (f - g)(x)
= f(x)-g(x)
= 2x³ + 7x² - 4x - 5-(3x-2)
= 2x³ + 7x² - 4x - 5-3x+2
= 2x³ + 7x²-7x-3
h(x) = (f - g)(x) = 2x³ + 7x²-7x-3
∴ (f - g)(x) = 2x³ + 7x²-7x-3

PLEASE HELPPPPPP. I NEED IT DONEEEEE.
Answer:
1. Couples tickets: $8
Individual tickets: $4
2. Song download cost: $2
Movie download cost: $15
Step-by-step explanation:
You can solve both of these questions by doing system of equations.
Let's start with question 1.
There are 2 variables in this equation:
- Couples tickets price: let's represent these with the letter C
- Individual tickets price: let's represent these with the letter K
Writing the two equations would look this these:
5c + 2k = 48
3c + 2k = 32
Next, isolate a variable. I am going to isolate K in the first equation.
[tex]2k = -5c + 48 \\k = -\frac{5}{2}c + 24[/tex]
Now that we isolated a variable we can plug that back in to the second equation:
[tex]3c + 2(-\frac{5}{2}c + 24) = 32\\3c - \frac{10}{2}c + 48 = 32\\3c -5c + 48 = 32\\-2c + 48 = 32\\-2c = -16\\c = 8[/tex]
We found that c is equal to 8 so we can put that back in to an equation to solve for k.
5(8) + 2k = 48
40 + 2k = 48
2k = 8
k = 4
Therefore, the price for couples tickets is $8 and the price for individual tickets is $4.
Check #1:
5(8) + 2(4) = 48
40 + 8 = 48
48 = 48
3(8) + 2(4) = 32
24 + 8 = 32
32 + 32
Now, let's go on to question 2.
There are 2 variables in this equation:
- Price of songs downloaded: let's represent these with S
- Price of movies downloaded: let's represent these with M
Writing the two equations would look like this:
15s + 11m = 195
15s + 8m = 150
There is a simple way to answer this system, however.
If you change the bottom equations signs to negative you can minus the second equation from the first equation like this:
15s + 11m = 195
-(15s +8m = 150)
Minus them to get this equation:
3m = 45
Solve
m = 15
We have found that each movie download costs $15, now let's plug this back into an equation:
15s + 11(15) = 195
15s + 165 = 195
15s = 30
s = 2
Each song costs $2 to download.
Check #2:
15(2) + 11(15) = 195
30 + 165 = 195
195 = 195
15(2) + 8(15) = 150
30 + 120 = 150
150 = 150

The formula to convert from Celsius to Fahrenheit is
F=95C+32 . Use this formula to complete the statements below. Round your answers to the nearest tenth as needed.
If the temperature is 78 degrees Fahrenheit , that is equivalent to
degrees Celsius.
If the temperature is 41 degrees Celsius, that is equivalent to
degrees Fahrenheit.
The temperature in Celsius will be 25.5556 °C and he temperature in degree Fahrenheit will be 105.8 °F, respectively.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the function to convert temperature from Celsius to Fahrenheit is F=(9/5)C+32.
A.) Given that If the temperature is 78 degrees Fahrenheit. Therefore, the temperature in degree Celsius will be,
F = (9/5)C + 32
78 = (9/5)C + 32
78 - 32 = (9/5)C
46 = (9/5)C
C = (46 × 5)/9
C = 25.5556
Hence, the temperature in Celsius will be 25.5556 °C.
B.) Given that the temperature is 41 degrees Celsius. Therefore, the temperature in degree Celsius will be,
F = (9/5)C + 32
F = (9/5)41 + 32
F = 73.8 + 32
F = 105.8
Hence, the temperature in degree Fahrenheit will be 105.8 °F.

A ticket service is selling tickets to a concert. An order of 4 tickets has a price of $63 and an order
of 6 tickets has a price of $92. Write an equation to find the price of any amount of tickets.
Answer:
y = 14.5x + 5
Step-by-step explanation:
x = Number of tickets for the concert
y = Price of the order of x tickets
y = 14.5x + 5
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Order of 4 tickets has a price of $63
Order of 6 tickets has a price of $92
2. Write an equation to find the price of any amount of tickets.
Let's find out the price of a ticket to understand if there's a service fee and how much is it, this way:
Price of a ticket = (Order of 6 tickets - Order of 4 tickets)/2
Price of a ticket = (92 - 63)/2
Price of a ticket = 29/2 = 14.50
If a ticket costs $ 14.50, 4 tickets will cost $ 58 and 6 tickets will cost $ 87, therefore there is a service or delivery fee of $ 5.
Order of 4 tickets - Price of 4 tickets = Service or delivery fee
Replacing, we have:
63 - 58 = 5
Order of 6 tickets - Price of 6 tickets = Service or delivery fee
Replacing, we have:
92 - 87 = 5
Now, we can write the equation to find the price of an order of any amount of tickets, this way:
x = Number of tickets for the concert
y = Price of the order of x tickets
y = 14.5x + 5

You can multiply them, but since 3 is multiplied by "a" or a different number than "b" then the answer would be incorrect.
Answer:
because 3a and 3b have different variables. You can't add "unlike terms" to each other because the variables have different values. by writing 3a+2b as 5ab, you're completely changing the meaning of the problem.
