A shoe distributor sells a particular pair of shoes to a store for $42.80. The store then sells this pair of shoes to a customer at a 35% markup. How much money does the store make from selling one pair of shoes to a customer?
Answer:
$14.98
Step-by-step explanation:
The store bought the pair of shoes for $42.80.
If the store sells the pair of shoes at a 35% markup, then it is selling it at:
([tex]\frac{35}{100}[/tex] × 42.80 ) + 42.80 = 14.98 + 42.80 = $ 57.78
To calculate how much money the store is making from selling this pair of shoes:
57.78 - 42.80 = $14.98
The store would be making $14.98 for selling one pair of shoes to a customer.

72 millimeters to 3 meters
The ratio is 24:1000 or 0.024.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
72 millimeters to 3 meters
Now, Convert 3 meter to millimeter
3 meter= 3 x 1000
= 3000 mm
Then, ratio is
= 72 / 3000
= 24/1000
= 0.024

The diagonals of rectangle. QRST intersect at P. Given that m<PTS = 34° and QS=10 , find QP.
Answer:
QP = 5
Step-by-step explanation:
since QRST is a rectangle, and QRST intersect at P, then QTS and QRS are right triangles.
because <T is a right angle, line TR passes through the midpoint of line QS, therefore 2(QP) = QS
10/2 = 5
By the property of diagonal in a rectangle are equal and bisect each other measure of QP is 5 units.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
Given, QRST is a rectangle, QS and RT are the diagonals of the rectangle
QRST.
By properties of rectangles, we know a rectangle is a parallelogram in which opposite sides are equal and diagonals bisect each other.
Given, QS is 10 units and QS = 2QP.
10 = 2QP.
QP = 10/2.
QP = 5.

Easy Cooking is a cooking supply company. Last year, the company sold a total of 5,340 ovens. This year, they sold 7,743 ovens. What is the percent of increase in the annual sales of ovens?
Answer:
45%
Step-by-step explanation:
Given data
Last year, the company sold a total of 5,340 ovens
This year, they sold 7,743 ovens
Percent increase= final-initial/initial*100
substitute
Percent increase= 7,743-5,340/5,340*100
Percent increase= 2403/5,340*100
Percent increase=0.45*100
Percent increase=45%
Hence the increase is 45%
What is the distance of
CD
given that
C (5,-2) and D (-3,8)
Leave your answer as a square root.
Answer:
CD = [tex]\sqrt{164}[/tex]
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = C(5, - 2) and (x₂, y₂ ) = (D(- 3, 8)
d = [tex]\sqrt{(-3-5)^2+(8+2)^2}[/tex]
= [tex]\sqrt{(-8)^2+10^2}[/tex]
= [tex]\sqrt{64+100}[/tex]
= [tex]\sqrt{164}[/tex]
= 2[tex]\sqrt{41}[/tex] ← in simplest form
As, we have C (5, - 2) and D (- 3, 8), to find CD let's use distance formula :
[tex] \underline{\boxed{\tt{Distance \: between \: two \: points = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}}}}}[/tex]
Here,
x₁ = 5x₂ = - 3y₁ = - 2y₂ = 8So, by filling values :
[tex] \sf : \implies CD = \sqrt{(-3 - 5)^{2} + (8 - (-2))^{2}}[/tex]
[tex] \sf : \implies CD = \sqrt{(-8)^{2} + (8 +2))^{2}}[/tex]
[tex] \sf : \implies CD = \sqrt{64 + (10)^{2}}[/tex]
[tex] \sf : \implies CD = \sqrt{64 + 100}[/tex]
[tex] \sf : \implies CD = \sqrt{164}[/tex]
Hence, distance of CD is [tex] \bold{\sf \sqrt{164}.}[/tex]
Factor out the greatest common
factor: -16x? + 12x?
Answer:
4x is the greatest common factor of those two.
Step-by-step explanation:
(-16x + 12x)
4x (-4 + 3)
4x is the GCF
Why you may ask is 4x the GCF because when you divide 4x from both you're left with -4 + 3...... you can't take out the negative from the 16 because when you check your work negative 4x times 3 gives you negative 12x which isn't the equation you started with. So positive 4x times 3 give you 12x.

In ΔMNO, the measure of ∠O=90°, the measure of ∠N=70°, and OM = 3.3 feet. Find the length of MN to the nearest tenth of a foot.
Answer:
Side MN = 3.5
Step-by-step explanation:
Side NO = 1.2011
Side OM = 3.3
Side MN = 3.51179
Angle ∠M = 20° = 0.34907 rad = π/9
Angle ∠N = 70° = 1.22173 rad = 7/18π
Angle ∠O = 90° = 1.5708 rad = π/2
Find the area of a circle whose area equals the half of the sum of the areas of two circles with radil 2 and 3.
13 (pi)
5 (pi)
6.5 (pi)
Step-by-step explanation:
step 1. if r = 2, then its area = (pi)r^2 = (pi)(4) = 4pi
step 2. if r = 3 then its area = (pi)r^2 = (pi)(9) = 9pi
step 3. so A is the area of a circle half the sum of our circles with r = 2 and r = 3.
step 4. A = (4pi + 9pi)/2 = 13pi/2 =6.5(pi).

ACME Company's expected sales can be modeled by g(t) = 13 – 21? + 4t - 7, where g(t) is measured in thousands
of dollars and t is the number of years after 2008. Find the average rate of change in expected sales from 2009 to
2015.
Select one:
O a. -$45,000
O b. $45,000
O c. $36,000
O d. $270,000
You can use the given function to evaluate the expected sales at year 2009 and 2015 and use the net difference divided by time as the average rate of change.
The average rate of change in expected sales from 2009 to 2015 is given by $12,059,941
How to find the average rate of change of something?Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:
[tex]\text{Average rate} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
where when
[tex]x = x_1, y = y_1\\and \\x = x_2, y = y_2[/tex]
Using the above method to calculate the needed average rateSince the sales is given by the function [tex]g(t) = t^3 - 2t^2 + 4t - 7[/tex], and the inputs are 2009 and 2015, thus, evaluating g(t) (sales) at those values of t, we get:
[tex]g(2009) = 8023737057[/tex] (replaced 2009 with t and calculated)
[tex]g(2015) = 8096096703[/tex] (replaced 2015 with t and calculated)
Using these values to calculate the average rate
[tex]\text{average rate} = \dfrac{g(2015) - g(2009)}{2015 - 2009} = \dfrac{72359646}{6} = 12059941\\[/tex]
Thus,
The average rate of change in expected sales from 2009 to 2015 is given by $12,059,941

Answer:
3x - 1 = 71
3x = 72
x = 24
Step-by-step explanation:
Answer:
Step-by-step explanation:
Simplifying
3x + -1 = 71
Reorder the terms:
-1 + 3x = 71
Solving
-1 + 3x = 71
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1' to each side of the equation.
-1 + 1 + 3x = 71 + 1
Combine like terms: -1 + 1 = 0
0 + 3x = 71 + 1
3x = 71 + 1
Combine like terms: 71 + 1 = 72
3x = 72
Divide each side by '3'.
x = 24
Simplifying
x = 24

Answer: what you need to find is the one where the two lowest numbers add up to be bigger than the biggest number. For example, if it was 3,7,5 then those could be right because 5+3=8 and 8 is bigger than 7. It is supposed to be that any two added is bigger than the third, but it's mist important that the smaller numbers equal more than the third

What is the measure of angle QZP
Answer:
22 degrees
Step-by-step explanation:
so if we take this here we know for sure that DZP is equal to 90 degrees
so DZP is split by QZD and QZP
so we take the 90 degrees we know for sure and then we take the two angle measurements we know
and we make this equation
9x + 5 + 3x + 1 = 90
and then we simplify this and it leaves us with
12x + 6 = 90
12x = 84
x = 7
so now that we have what x equals we plug that into QZP in order to find the actual measurement of this angle
3x + 1
3 (7) + 1
21 + 1
leaving us with our answer 22 degrees
and if you want to double check this answer just do the same thing we just did with QZD and plug in x into the equation and then add our answer 22 and the other answer you get for QZD and if that adds up to 90 then that is correct!

Kari estimated the quotient of Negative 12 and one-fifth divided by 4 and two-fifths to be –8. Which best describes her error?
Answer:
D. Kari added the compatible numbers –12 and 4.
Step-by-step explanation:
Kari estimated the quotient of Negative 12 and one-fifth divided by 4 and two-fifths to be –8. Which best describes her error?
-12 1/5 ÷ 4 2/5 = -8
A. Kari multiplied the compatible numbers –12 and 4.
-12 * 4 = 48
A. Is not correct
B. Kari found that the quotient of a negative number and a positive number is negative.
Example:
-a/a = -1
The rule is right
C. Kari found that the quotient of a positive number and a negative number is positive.
a/-a = -1
The rule is wrong
D. Kari added the compatible numbers –12 and 4.
= -12 + 4
= -8
Therefore, Kari error was that she added the compatible numbers –12 and 4.
