Based on the information given the selling price of the pen set is $189.
Using this formula
Selling price=Selling price of pen+(Profit percentage× Selling price of pen)
Let plug in the formula
Selling Price=$150 +( 26% ×$150)
Selling Price=$150 +$39
Selling Price=$189
Inconclusion the selling price of the pen set is $189.

I need Unit 3 parallel and perpendicular lines Homework 5 slope of lines it’s due today!
14. Slope (m) of PQ = -4
Slope (m) of RS = 1/4
The lines are perpendicular.
15. mPQ = -3
mRS = 3
They are neither perpendicular nor parallel lines.
16. mPQ = 0
mRS = 0
The lines are parallel.
17. x = -6
18. x = -2
What are the Slopes of Parallel and Perpendicular Lines?If two lines have the same slope (m), then both lines are parallel to one another. On the other hand, if the slopes of two lines are negative reciprocals to each other, then both lines are regarded as perpendicular lines because the product of their slopes is equal to -1.
Slope (m) = change in y / change in x
14. Slope (m) of PQ = (-3 - 17) / (1 -(-4))
Slope (m) of PQ = -20/5 = -4
Slope (m) of RS = (4 - 3) / (-5 -(-9))
Slope (m) of RS = 1/4
(1/4)(-4) = -1, therefore, the lines are perpendicular.
15. Slope (m) of PQ = (-1 - 14) / (2 -(-3))
Slope (m) of PQ = -15/5 = -3
Slope (m) of RS = (-10 - 8) / (-2 - 4)
Slope (m) of RS = -18/-6 = 3
They are neither perpendicular nor parallel lines.
16. Slope (m) of PQ = (-1 - (-1)) / (-3 - 2)
Slope (m) of PQ = -0/-5 = 0
Slope (m) of RS = (9 - 9) / (-7 -(-11))
Slope (m) of RS = 0/4 = 0
The lines are parallel.
17. If CD║EF, their slope will be equal. Therefore:
Slope of CD = slope of EF
(-4 - 16)/(2 - x) = (4 - 14)/(-2 -(-6))
-20/(2 - x) = -10/4
-20/(2 - x) = -5/2
Cross multiply

-40 = -10 + 5x
-40 + 10 = 5x
-30 = 5x
-30/5 = x
-6 = x
x = -6
18. Slope of JK = slope of l
(-5 -(-8))/(-1 - x) = 6/2

Which of the ordered pairs are solution to 4+3x=-2y
Answer:
I Believe the answer is (3x,-6y)
Step-by-step explanation:
From your equation 4+3x=2y you first want to isolate the variable ( Variable means letter or number with letter), so you isolate 3x and dont do anything to it. You do the opposite of what the equation is telling you , so 4+3 will change to 4-3 , then you subtract 4 from 4 itself then from 6 making you get -6 then you bring down the 3x and you have your answer (3x,-6y) , I hope this helps.

In the figure below, a tangent and a secant are drawn to a circle from exterior point E.
Suppose that EG = 13 and ED=26. Find CD.
Answer:
19.5 = CD
Step-by-step explanation:
The square of the tangent = (length of the secant)(the length of the outside part of the secant)
EG² = (ED)(EC)
13² = (26)(EC)
169 = 26EC
169/26 = EC
6.5 = EC
Now ED = EC + CD
26 = 6.5 + CD
19.5 = CD
The value of the segment CD will be equal to 19.5.
What is secant and tangent?The relationship between the line segments produced by a secant and a tangent line and the corresponding circle is described by the tangent-secant theorem.
The square of the tangent = (length of the secant)(the length of the outside part of the secant)
It is given that In the figure below, a tangent and a secant are drawn to a circle from exterior point E. Suppose that EG = 13 and ED=26.
The value of the segment CD will be calculated as below:-
EG² = (ED)(EC)
13² = (26)(EC)
169 = 26EC
169/26 = EC
6.5 = EC
Calculate CD.
ED = EC + CD
26 = 6.5 + CD
19.5 = CD
Therefore, the value of the segment CD will be equal to 19.5.

A print shop charges $20 to set up the graphic for printing t-shirts. The store then charges $12 per shirt for purchasing up to 10 shirts. The charge decreases to $10 if a customer purchases 10-20 shirts. If a customer purchases more than 20 shirts, each shirt will cost $7. What will it cost a soccer team to have 15 shirts printed?right and grab a piecewise function that models the situation answer the question
Answer:
see below for the piecewise function$170 for 15 shirtsStep-by-step explanation:
The cost function c(n) for n T-shirts can be written according to the problem statement:
[tex]c(n)=\begin{cases}20+12n&\text{for }n<10\\20+10n&\text{for }10\le n\le20\\20+7n&\text{for }n>20\end{cases}[/tex]

A can of soup is a cylinder with diameter 7 cm.
The can is 10 cm high
The can is full of soup
soup
The soup is poured into a saucepan.
The saucepan is a cylinder with diameter 12 cm.
Work out the depth of the soup in the saucepan.
Give your answer correct to 1 decimal place.
Answer:
3.4 cm
Step-by-step explanation:
We can solve this by calculating the volume of the soup and then figuring out the height of the soup in the saucepan from there.
Cylinder volume: πr²h
r = 0.5 * diameter
volume of soup: π(3.5)²10 ≈ 384.845
volume of soup in saucepan: 384.845
For saucepan:
πr²h = π(6)²h = volume = 384.845
36πh = 384.845
divide both sides by 36π to isolate h
h ≈ 3.4 cm

Answer:
The answer is Student 1 and 3.
Step 1: Break down each multiple-choice.
Student 1: -(5r-3s+1)
Given the distributive law of multiplication, -, which is also known as -1, should be multiplied by every other term in the expression, which gives us -5r+3s-1
Student 2: -5r+3s+1 (given)

Answer:
374mm squared
Step-by-step explanation:
Bottom rectangle can be cut off to equal 52mm, by multipling 4 by 13
the rest is 14*23, which equals 322mm
add those together to get 374mm squared
Answer:
374 square millimeters
Step-by-step explanation:
First, we can split the shape into 2 rectangles.
This will give us a rectangle with a width of 13 and 10.
Let's work out 1 rectangle at a time.
Area of a rectangle=Width times by legth
13*18=234- This is the area of 1 of the rectangles.
10*14=140- This is the area of the second rectangle
Now we add the areas together to get 374 square millimeters, which is the area of this figure.
