The Shoe Outlet bought boots for $60 and marks up the boots 55% on the selling price. What is the selling price of the boots?
Answer: The markup- 122.225%
Revenue/price- 133.33$
Gross profit- 73.33%
Step-by-step explanation:
The gross profit P is the difference between the cost to make a product C and the selling price or revenue R.
P = R - C
To calculate revenue R based on the cost C and the desired gross margin G, where G is in decimal form:
R = C / ( 1 - G)
The gross profit dollars P is the revenue dollars R from the sale times the gross margin G percentage, where G is in decimal form :
P = R * G
The markup percentage M, in decimal form, is gross profit P divided by cost C.
M = P/ C
M * 100 will change the decimal to a percentage.
The selling price of the boots is $93.
Given information:
The Shoe Outlet purchased the boots for $60 and increased their price by 55%
To calculate the selling price of the boots with a 55% mark-up, to add 55% of the original cost to the original cost.
Calculate the mark-up amount as follows:
Mark-up = 55% of $60
Mark-up = 0.55 * $60
Mark-up = $33
Add the mark-up to the original cost to find the selling price as follows:
Selling Price = Original Cost + Mark-up
Selling Price = $60 + $33
Selling Price = $93
So, the selling price of the boots is $93.

Hi there!
Parabola x² = 12y
→ x² = 4ay
→ 4a = 12
→ a = 12÷4
→ a = 3
So, the co-ordinates of the focus is:-
S(0,a)=(0,3)
→ Let AB be the latus rectum of the given parabola.
→ Coordinates of end-points of latus rectum are (-2a,a), (2a,a)
→ Coordinates of A are (-6,3), while B's coordinates are (6,3).
→ ∆OAB are O(0,0), A(-6,3), B(6,3)
Area of ∆OAB is :-
(Solving part attached as image)
=> 18 unit² is the required answer.
Answer:
18 sq. unit
Step-by-step explanation:
Parabola is x²=12y
On comparing it with
→x²=4ay
→4a=12
→a=12/4
→a=3
Finding the value of x.
→x²=12y
→x²=12×3
→x²=36
→x=√36
→x=6
When we have a=3 and x=6
(-x1,a)=(-6,3)
(x1,a)=(6,3)
Let,
(x1,y1)=(0,0)
(x2,y2)=(6,3)
(x3,y3)(-6,3)
Now,
Area=[tex]=\frac{1}{2} *b*h\\\\=\frac{1}{2} [x1(y2-y3)+x2(y3-y1)+x3(y1-y2)\\\\=\frac{1}{2} [0(3-3)+6(3-0)+(-6)(0-3)\\\\=\frac{1}{2} [18+18]\\\\\\=18.sq.units[/tex]
We can calculate E, the amount of euros that has the same value as D.S. dollars, using the equation E= 17/20 D.
How many euros have the same value as 1 U.S. dollar?
How many U.S. dollars have the same value as 1 euro?
Answer:
0.85
1.176
Step-by-step explanation:
E = 17/20 D
Let D = 1,
E = 17/20 × 1
E = 17/20 = 0.85
1 dollar = 0.85 Euro
E = 17/20 D
17/20 D = E
D = 20/17 E
Let E = 1,
D = 20/17 × 1
D = 1.176
1 Euro = 1.176 dollar

Answer:
x = y = 24.
Step-by-step explanation:
Here we are given a right angled triangle in which one of the angles is 45° . And one of the known side is 24√2 . And we need to find out the value of x and y.
Here we can use the ratio of sine as ,[tex]\qquad\rm\longrightarrow sin45^o =\dfrac{p}{b} [/tex]
Substituting the respective values,
[tex]\qquad\rm\longrightarrow sin45^o =\dfrac{x}{24\sqrt2}[/tex]
Value of sin 45° is 1/√2 . So that,
[tex]\qquad\rm\longrightarrow \dfrac{1}{\sqrt2}=\dfrac{x}{24\sqrt2}[/tex]
Cross multiply ,
[tex]\qquad\rm\longrightarrow x =\dfrac{24\sqrt2}{\sqrt2} [/tex]
Simplify,
[tex]\qquad\rm\longrightarrow \underline{\boxed{\rm \blue{x = 24}}} [/tex]
Again , the third angle will be 45° . we know that the sides opposite to equal angles are equal. Therefore here ,
[tex]\qquad\rm\longrightarrow \underline{\boxed{\blue{\rm y = 24}}}[/tex]
The values of x and y are 24
The triangle is a right angled triangle with an angle measure of 45 degrees.
The above means that:
The values of x and y are equal
So, we have:
[tex]x^2 + y^2 = (24\sqrt 2)^2[/tex]
Evaluate the squares
[tex]x^2 + y^2 = 1152[/tex]
x and y have equal values,
So, we have:
[tex]x^2 + x^2 = 1152\\\\[/tex]
[tex]2x^2 = 1152[/tex]
Divide through by 2
[tex]x^2 = 576[/tex]
Take the square roots of both sides
[tex]x = 24[/tex]
Hence, the values of x and y are 24

2) 50°
3) 50°
Reasons: rhombus, perpendicular bisector
- Toodles!~
[tex]\bold{\huge{\pink{\underline{ Solutions}}}}[/tex]
Answer 18 :-We have,
Rhombus RAMS and Angle SMA = 100°
In rhombus, The diagonals bisect each other at an angle of 90° .Therefore,
[tex]\sf{\angle{ AMR = 1/2}}{\sf{\angle{ SMS}}}[/tex]
[tex]\sf{\angle{ AMR = 1/2 × 100 }}[/tex]
[tex]\sf{\angle{ AMR = 50° }}[/tex]
Thus, Angle AMR is 50°
Hence, Option D is correct
Answer 19 :-We know that,
The sides of rhombus are equal and parallel to each other[tex]\sf{\angle{ AMR = }}{\sf{\angle{ RMS}}}[/tex]
[ Alternative interior angles ]
[tex]\sf{\angle{ RMS = 50° }}[/tex]
Thus, The value of Angle RMS is 50°
Hence, Option B is correct
Answer 20 :-Here, we have to find the value of mAngleMSA
In ΔCMS,
By using Angle sum property
[tex]\sf{ 50° +}{\sf{\angle{MSC + 90° = 180° }}}[/tex]
[tex]\sf{\angle {MSC = 180° - 140°}}[/tex]
[tex]\sf{\angle{MSC = 40° }}[/tex]
Therefore,
[tex]\sf{m}{\sf{\angle{MSA = 40° }}}[/tex]
Thus, The value of mAngle MSA is 40°

Answer:
C, D and F
Step-by-step explanation:
volume of a cuboid = W x L x H
(where W = width, L = length and H = height)
Calculate the volume of each of the prisms (cuboids), then compare their volume with the range of 25 - 40 cubic units
Volumes
A: 4 x 4 x 4 = 64 cubic units
B: 3 x 7 x 2 = 42 cubic units
C: 4 x 4 x 2 = 32 cubic units
D: 2 x 6 x 2 = 24 cubic units
E: 3 x 5 x 3 = 45 cubic units
F: 2 x 3 x 6 = 36 cubic units
Therefore, prisms C, D and F have a volume between 25 and 40 cubic units.

How can you change the dimensions of the rectangle so that the ratio of the length to the width stays the same, but the perimeter is 185 centimeters? l=25cm h=12cm
Answer:
Width= 30
Length= 62.5
Step-by-step explanation:
First we simplify the length to width ratio
25/12=
2 1/12 ratio of length to width
width=x
length=2 1/12x
Make the equation for this ratio's perimeter being equal to 185
2(2 1/12x) + 2(x)=185
Solve for x
4 1/6x +2x=185
6 1/6x=185
x=30
Substitute the answer in for x to find the length and width
Width= 30
Length= 2 1/12(30)
Length= 62.5

find x and y
4x-4y=0
y= 2x+6
Answer:
x = -6
y = -6
Step-by-step explanation:
Solve using substitution.
Substitute 2x + 6 for y:
4x - 4(2x + 6)=0
Distribute the 4 to each term in the parentheses:
4x - 4(2x) - 4(6) = 0
4x - 8x - 24 = 0
Combine like terms
-4x - 24 = 0
Add 24 to both sides
-4x = 24
Divide both sides by -4
x = -6
Plug -6 back in for x to solve for y:
y = 2x + 6 = 2(-6) + 6 = -12 + 6 = -6
(x, y) = (-6, -6)
Answer:
x= -6 and y= -6
Step-by-step explanation:
Take 4x-4y=0 as eqn 1
and y=2x+6 as eqn 2
Substitute eqn 2 into eqn 1
4x -4(2x+6)=0
4x-8x-24=0
-4x-24=0
Move -24 to the other side
-4x=24
Divide both sides by -4
[tex] \frac{ - 4x}{ - 4} = \frac{24}{ - 4} [/tex]
x= -6
substitute x= -6 in eqn 2
y=2(-6)+6
y= -12+6
y= -6
