A music company sells CDs for a particular artist. The company has advertising cost of $4,000 and recoding costs of $10,000; Their cost for manufacturing, royalties, and distribution are $5.50 per CD. They sell the CDs to Mage-Mart for $7.20 each
Answer:
Instructions are below.
Step-by-step explanation:
Giving the following information:
Fixed costs= 4,000 + 10,000= $14,000
Unitary variable cost= $5.5
Selling price= $7.2
To calculate the number of units to be sold to break-even, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 14,000 / (7.2 - 5.5)
Break-even point in units= 8,235 units
In dollars:
Break-even point (dollars)= fixed costs/ contribution margin ratio
Break-even point (dollars)= 14,000 / (1.7/7.2)
Break-even point (dollars)= $59,294
Now, imagine the company requires a profit of $50,000:
Break-even point in units= (fixed costs + desired profit) / contribution margin per unit
Break-even point in units= 64,000/1.7
Break-even point in units= 37,647 units
Break-even point (dollars)= (fixed costs + desired profit) / contribution margin ratio
Break-even point (dollars)= 64,000 / (1.7/7.2)
Break-even point (dollars)= $271,059

Answer:
(C) 50π
Step-by-step explanation:
For this problem, we need to find a way to relate the inner circle, to the square, to the outer circle.
Given that we know the area of a circle is πr^2, and our inner circle has a area of 25π, we can find the radius.
25π = πr^2
25 = r^2
5 = r
Note, that the diameter of the inner circle is parallel to the side of the square, meaning that the diameter of the inner circle is the length of the side of the square.
diameter = 2 * radius
d = 2 * 5 = 10.
Now that we know the value of the side of the square, we can find the length of the diagonal of the square, which is the diameter of the outer circle.
Using the properties of the 45-45-90 right triangle, we can say that the diagonal of the square is the length of the side times sqrt(2).
Outer_Diameter = 10 * sqrt(2)
Now to find the outer area, we need the formula for the area of a circle. Note that the diameter is twice the radius, so we will simply divide by 2.
A = πr^2
A = π * [ ( 10 * sqrt(2) ) / 2 ]^2
A = π * [ 5 * sqrt(2) ] ^2
A = π * 25 * 2
A = 50π
So the area of the outer circle is 50π.

During a trip Sara knits a scarf at the rate of 469 millimetre everyday if her trip lasts 8 days how much of the scar will she have knitted by the end of the trip
Answer:
3752mm or 3752 millimeter
Step-by-step explanation:
We are told in the question that Sara knits 469 mm everyday.
Hence, this can be expressed as:
1 day, she knits = 469 mm
8 days =
Cross Multiply
469mm × 8
= 3752mm
Therefore the amount of scarft she would have knitted after 8 days = 3752mm

Answer:
16x -2
Step-by-step explanation:
You know how to compute the perimeter of a rectangle of length L and width W:
P = 2(L+W)
Here, you're asked to use the given algebraic expressions for length and width and simplify the result of putting those in the perimeter formula.
P = 2((5x-2) +(3x+1))
P = 2(8x -1)
P = 16x -2 . . . the perimeter of the rectangle

what is the answer to 7x-35=30+6x
Answer:
x=65
Step-by-step explanation:
you have to get all variables to one side so you would subtract 6 from seven getting one and then add 35 to 30 giving you 65 :)
Answer:
x = 65
Step-by-step explanation:
7x - 35 = 30 + 6x First subtract 6x from both sides
x - 35 = 30 Then add 35 to both sides
x = 65

Simplify: [tex]\frac{1}{(x+3)(x+4)} +\frac{2}{(x+4)(x+5)}[/tex]
Answer:
[tex]\frac{3x+11}{(x+3)(x+4)(x+5)}[/tex]
Step-by-step explanation:
Before adding we require the fractions to have a common denominator.
Multiplying the numerator/ denominator of the first fraction by (x + 5)
Multiplying the numerator/ denominator of the second fraction by (x + 3)
= [tex]\frac{x+5}{(x+3)(x+4)(x+5)}[/tex] + [tex]\frac{2(x+3)}{(x+3)(x+4)(x+5)}[/tex]
Now add the numerators leaving the common denominator
= [tex]\frac{x+5+2x+6}{(x+3)(x+4)(x+5)}[/tex]
= [tex]\frac{3x+11}{(x+3)(x+4)(x+5)}[/tex]
what is the answer to this equation 5r+2<17
Answer:
r < 3
Step-by-step explanation:
Step 1: Write out inequality
5r + 2 < 17
Step 2: Subtract 2 on both sides
5r + 2 - 2 < 17 - 2
5r < 15
Step 3: Divide both sides by 5
5r/5 < 15/5
r < 3
In this case, r has to be smaller than 3. So anything like -2, -15, or even -12413573875942 works as r, as long as it's smaller than 3.

2(n+2)=4n+1-2n
Whats the answer
Answer:
no solution
Step-by-step explanation:
Given
2(n + 2) = 4n + 1 - 2n ← distribute parenthesis on left side
2n + 4 = 2n + 1 ( subtract 4 from both sides )
2n = 2n - 3 ( subtract 2n from both sides )
0 = - 3 ← not possible
This indicates the equation has no solution
The original equation 2(n + 2) = 4n + 1 - 2n has no solution for n.
To solve the equation 2(n + 2) = 4n + 1 - 2n, we can simplify and then solve for the variable n.
First, distribute 2 to the terms inside the parentheses:
2n + 4 = 4n + 1 - 2n
Next, combine like terms on the right side:
2n + 4 = 2n + 1
Now, subtract 2n from both sides to isolate the n term:
2n - 2n + 4 = 2n - 2n + 1
4 = 1
Since 4 is not equal to 1, there is no solution to this equation.
Therefore, the original equation 2(n + 2) = 4n + 1 - 2n has no solution for n.

Step-by-step explanation:
Jim and Lynn were asked to find the coordinates of the midpoint of the segment whose endpoints are R (−15, −8) and S (−5, −2). Jim used point S as ( x 1 , y 1 ). Lynn said he had to use point R as ( x1 , y 1 ). Who is correct? Explain.
Answer:
Both Jim and Lynn, as midpoint formula observes commutative property, which commutes the position of each endpoint inside the sum without altering the result.
Step-by-step explanation:
We must remember that location of midpoint of any line segment can be determined by using this formula in function of the endpoint locations:
[tex](x_{M},y_{M}) = \left(\frac{x_{R}+x_{S}}{2}, \frac{y_{R}+y_{S}}{2} \right)[/tex]
Where:
[tex]x_{M}[/tex], [tex]y_{M}[/tex] - Location of midpoint, dimensionless.
[tex]x_{R}[/tex], [tex]y_{R}[/tex] - Location of endpoint R, dimensionless.
[tex]x_{S}[/tex], [tex]y_{S}[/tex] - Location of endpoint S, dimensionless.
Both Jim and Lynn, as midpoint formula observes commutative property, which commutes the position of each endpoint inside the sum without altering the result. That is:
[tex](x_{M},y_{M}) = \left(\frac{x_{R}+x_{S}}{2}, \frac{y_{R}+y_{S}}{2} \right) = \left(\frac{x_{S}+x_{R}}{2}, \frac{y_{S}+y_{R}}{2} \right)[/tex]
