A ceramic vase that cost an antique store $7 was marked $63. What is the percentage markup on the price of the ceramic vase?
A-56%
B-900%
C-800%
D-44%
9514 1404 393
Answer:
C) 800%
Step-by-step explanation:
The markup amount is the difference between the selling price and the cost:
markup = selling price - cost
markup = $63 -7 = $56
The percentage markup relative to the cost is ...
markup/cost × 100%
= ($56)/($7) × 100%
= 8×100% = 800%

What is the area of the figure?
Enter your answer in the box.
in2
Answer:
The bottom edge of the right triangle is: 16in -10in = 6in
So the area of the triangle is: S1 = 1/2 (a x b) = 24/2 = 12m2
the area of a square is: S2 = a ^ 2 = 10 ^ 2 = 100m2
The total area of the figure is: S1 + S2 = 12 + 100 = 112 m2
Step-by-step explanation:
identify the diameter of Q given that a= 169 pie in2
Answer:
the diameter will be D=26 in.
Step-by-step explanation:
The area of a circle is given by:
[tex]A=\pi R^{2}[/tex] (1)
Where:
A is the areaR is the radius of the circleNow, we know that A = 169 π in²
So, we just need to use equation 1 to find R.
[tex]169\pi = \pi R^{2}[/tex]
[tex]R=\sqrt{169}[/tex]
[tex]R=13 \: in[/tex]
Therefore, the diameter will be D=2*R=26 in.
I hope it helps you!
The diameter of the circle is 26 inches
The area of the circle is given as:
[tex]A = 169\pi[/tex]
The area of a circle is calculated as:
[tex]A = \pi r^2[/tex]
By comparison, we have:
[tex]\pi r^2 = 169\pi[/tex]
Divide both sides of the equation by pi
[tex]r^2 = 169[/tex]
Take the positive square roots of both sides
[tex]r = 13[/tex]
Multiply by 2, to calculate the diameter
[tex]d =2 * 13[/tex]
[tex]d = 26[/tex]
Hence, the diameter of the circle is 26 inches

The scale of a room in a blueprint is 5 in.: 9 ft. A wall in the same blueprint is 30 in. Complete the table.
Blueprint length (in.) 5
10
15
20
25
30
Actual length (ft)
9
How long is the actual wall?
The actual wall is
feet long
A window in the room has an actual width of 4.5 feet. Find the width of the window in the blueprint.
The width of the window in the blueprint is
in.
Answer:
54 feets
2.5 inches
Step-by-step explanation:
Given that:
Scale model:
5 in : 9ft
If 5 in = 9 ft
Hence, 1 in on the blue print equals
5 in = 9 ft
1 in = x
Cross multiply
5x = 9
x = 9/5 feets
Hence, 1 inches on the blueprint equals 9/5 feets actual
Blueprint length (in.) ___ Actual length (ft)
5 _________ 9
10 ________ 18
15 ________ 27
20 _______ 36
25 _______ 45
30 _______ 54
Hence ;
5 * 9/5 = 9 feets
10 * 9/5 = 18 feets
15 * 9/5 = 27 feets
20 * 9/5 = 36 feets
25 * 9/5 = 45 feets
30 * 9/5 = 54 feets
Window with actual width of 4.5 feets
Width of window in blue print :
Actual width ÷ 9/5
Actual width = 4.5 = 4 1/2 = 9/2
9/2 * 5 /9
= 5 /2
= 2 1/2 inches = 2.5 inches

If JK = 8x + 24 and NO = 20, what is the value of x?
Answer:
x=2
Step-by-step explanation:
So..
NO=1/2 of JK because the two segments are parallel
Therefore because you have NO plug that into..
NO=1/2JK
YOU GET
1/2JK=20 multiply 2 so you can isolate JK
JK=40
Then plug that back into your JK=8x+24
40=8x+24 next subtract 24 on both sides
8x=16
x=2
