A music store bought a CD set at a cost of $20. When the store sold the CD set, the percent markup was 40%. Find the selling price.
Answer:
$28
Step-by-step explanation:
cp=20
mp=20%ofcp
=20/100*20
=8
now,
sp=mp+cp
=8+20
=28
the slope is 6 and passes through (-4,4)
Answer:
y=6x+28
Step-by-step explanation:
Using the given variables, find the equation of the line using y=mx+b
In this equation, m=slope, which means m=6
So now we have y=6x+b. We need to find the b value.
Plug in the point (-4,4) into the equation and solve for b like so:
y=6x+b
4=6(-4)+b
28=b
Now, plug in your m value and b value into y=mx+b to get your answer of y=6x+28

The length of a rectangle is 2 ft shorter than 5 times its width, x. The area of the rectangle is less than 100 f12.
Which inequality can be used to determine the maximum width (ft) of the rectangle?
A. 5x2 – 2x < 100
OB. 5x2 - 2x > 100
O C. 5x2 + 2x > 100
D. 5x2 + 2x < 100
HELPPP PLS!!
Answer:
A
Step-by-step explanation:
Area of rectangle = length x width
length = 5x - 2
width = x
area = (5x - 2) × x
100 = 5x² - 2x
the width would be less than the area of the rectangle, thus the inequality sign to be used is <
5x² - 2x < 100

What is the slope of the line that passes through the points (4, 9)(4,9) and (7, 18) ?(7,18)? Write your answer in simplest form.
Answer:
Slope = 3
Step-by-step explanation:
Calculate using slope formula: [tex]m = \frac{y2-y1}{x2-x1}[/tex]
[tex](x1, y1) = (4, 9)[/tex] and [tex](x2, y2) = (7, 18)[/tex]
[tex]m = \frac{18 - 9}{7 - 4} = \frac{9}{3} = 3[/tex]

In Venn diagrams, similarities in both things are in the middle of the diagram, but we also have the others.
Therefore, there are 41 students who like tennis and swimming.
Students who don't like tennis like swimming, so that's 17.
Therefore, there are 17 students who don't like tennis.

What is the complete factorization of x2 + 4x − 45?
Answer:
(x + 9)(x - 5)
Step-by-step explanation:
x^2 + 4x - 45
factorising by using middle term break method
=x^2 + (9 - 5)x - 45
=x^2 + 9x - 5x - 45
=x(x + 9) - 5(x + 9)
=(x + 9)(x - 5)
solve by the substitution method
6x+5y =-26
-9x+y= 56

Answer:
Step-by-step explanation:
[tex]1)Divide \ (6x^2 + x -12) \ by \ (2x + 3)[/tex]
[tex]6x^2 + x -12 = 6x^2 + 9x - 8x -12[/tex]
[tex]=3x(2x + 3)-4(2x + 3)\\\\=(3x -4)(2x + 3)[/tex]
[tex]\frac{6x^2 + x -12}{2x + 3} = \frac{(3x -4)(2x+3)}{(2x+3)} = (3x -4)[/tex]

What are the roots of 5x^2=60
Answer: {±2√3}
Step-by-step explanation: Since only one term contains an x in this problem, we can simply get the x by itself by dividing both sides by 5 and then square rooting both sides to get x = ±√12
Remember to use plus or minus when
square rooting both sides of an equation.
Now, √12 breaks down to 2√3 so our
final answer is {±2√3}.
If the variable only appears in one of the terms in the equation,
you can solve it by simply isolating the variable.
I don’t know what to do?
Answer:
I geuss because the scale factor is 2 that the resulting triangle will be almost twice the size. Because in a dilation you multiply it. If you dont know how to dilate a triangle with a compass I would suggest looking for a video online. But I know for the part that says "Is the image of ABC similar to the original triangle" the answer would be yes it is similar because you are just dilating the triangle not changing its orientation. I hope this helps! Good luck!
The figure above shows a circle with center Cand
radius 6. What is the sum of the areas of the two
shaded regions?
160
С
Answer:
Sum of the areas of two shaded regions = 100 unit² (Approx.)
Step-by-step explanation:
Given:
Radius of circle = 6 units
Angle of one unshaded area = 160'
Find:
Sum of the areas of two shaded regions
Computation:
Angle of one shaded area = 180' - 160'
Angle of one unshaded area = 20'
Sum of the areas of two shaded regions = 2[θ/360][πr²]
Sum of the areas of two shaded regions = 2[160/360][(3.14)(6)²]
Sum of the areas of two shaded regions = 2[160/360][(3.14)(36)]
Sum of the areas of two shaded regions = 2[160/360][(3.14)(36)]
Sum of the areas of two shaded regions = [0.888][113.04]
Sum of the areas of two shaded regions = 100.46
Sum of the areas of two shaded regions = 100 unit² (Approx.)

This is the same as 7.5pi
============================================================
Explanation:
Refer to the previous post I answered a while back. It's a similar problem, just with different numbers.
Instead of following that exact route, I'll use a more direct route this time. I'll use the formula below
S = (x/360)*pi*r^2
where S is the area of the sector (aka pizza slice), x is the angle of the sector, and r is the radius.
Notice the x/360 portion represents taking a fractional part of the full circle area pi*r^2
-----------------------
Plugging in the given values leads us to...
S = (x/360)*pi*r^2
S = (108/360)*pi*5^2
S = (3/10)*pi*25
S = (3/10)*25*pi
S = 75pi/10
S = 15pi/2
This is the same as 7.5pi because 75/10 = 15/2 = 7.5
I'll leave it as a fraction since the previous answer I wrote was in fraction form.
-------------------------
Side note: if the angle x is in radian mode, then you'll use this formula
S = (x/2)*r^2
Answer:
7.5π square meters
Step-by-step explanation:
The formula for the area of a sector (when angle is given in degrees) is: [tex]A=\frac{\theta}{360}\pi r^{2}[/tex]
Where r is the radius, and [tex]\theta[/tex] is the angle of the sector in degrees.
We are given the information that the radius = 5m, and [tex]\theta[/tex] = 108 degrees. So now we can just substitute these values into the equation to solve for A:
[tex]A=\frac{108}{360}\pi 5^{2}\\\\A=0.3\pi * 25\\A = 7.5\pi[/tex]
(OR approx. 23.56 square meters)
Hope this helped!
