x/4+9=15 I'm doing a math assignment.
Answer:
x = 24
Step-by-step explanation:
x/4+9=15
Subtract 9 from each side
x/4+9-9=15-9
x/4 = 6
Multiply each side by 4
x/4*4 = 6*4
x = 24
Answer:
[tex]x = 24[/tex]
Step-by-step explanation:
[tex] \frac{x}{4} + 9 = 15 \\ \\ \frac{x}{4} = 15 - 9 \\ \frac{x}{4} = 6 \\ 4 \times \frac{x}{4} = 6 \times 4 \\ x = 24[/tex]

Step-by-step explanation:
Quincy folds a piece of cardboard to make the three sides of a triangular prism open at top and bottom. The triangle prism and the piece of cardboard that he used are show below. What is the area of the piece of cardboard?
This question is incomplete because it lacks the attached diagram.
Find attached to this answer the appropriate diagram
Answer:
500 square centimeters
Step-by-step explanation:
From the question above, we are told that the top and bottom of the triangular prism is open.
Hence, the area of the piece of the cardboard is = Lateral Surface Area of the triangular prism
The formula for Lateral Surface Area of a Triangular Prism = Perimeter of the Triangular prism × Height of the Triangular prism.
Perimeter of the Triangular prism = Side a + Side b + Side c
Where Side a = 9cm
Side b = 9cm
Side c = 7 cm
Perimeter of the Triangular prism = 9cm + 9cm + 7cm
= 25cm
Height of the Triangular prism = 20cm
The Lateral Surface Area of the Triangular prism = 25cm × 20cm
= 500cm² or 500 square centimeters.
Since we are told that Lateral Surface Area = Area of the cardboard,
The Area of the cardboard = 500 cm² or 500 square centimeters.

Answer:

Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AD}{WZ}[/tex] = [tex]\frac{CD}{YZ}[/tex] , substitute values
[tex]\frac{10}{46}[/tex] = [tex]\frac{5}{YZ}[/tex] ( cross- multiply )

A can of soup has a radius of 6 inches and a height of 10 inches. How much soup can fill the can if it is filled to the top? Place your answer in terms of pi.
A can of soup is a cylinder. We want to know how much soup can fill the can, which means that we are looking for the volume.
Formula for the volume of a cylinder: V = pi x r^2 x h
V = pi x 6^2 x 10
V = pi x 36 x 10
V = 360pi inches^3

Answer:
CD player X
Step-by-step explanation:
In this question we are asked to compare 3 CD prices to each other and see which one is the cheapest. We will need to use something called decimal multipliers for this question. We will work out the price of each CD player and then analyse after that. To work out the decimal multipliers for decrease question you have minus 100 and then divide by 1 hundred.
CD player X
→ A price of 1500 and 20% off
⇒ Work out the multiplier with the 100 and then divide by a hundred
→ 100 - 20 = 80 → 80 ÷ 100 = 0.8 So the decimal multiplier is 0.8
⇒ Now multiply the price by the decimal multiplier
→ 1500 × 0.8 = 1200
-------------------------------------------------------------------------------------------------------
CD player Y
→ A price of 2000 and 30% off
⇒ Work out the multiplier with the 100 and then divide by a hundred
→ 100 - 30 = 70 → 70 ÷ 100 = 0.7 So the decimal multiplier is 0.7
⇒ Now multiply the price by the decimal multiplier
→ 2000 × 0.7 = 1400
-------------------------------------------------------------------------------------------------------
CD player Z
→ A price of 1800 and 25% off
⇒ Work out the multiplier with the 100 and then divide by a hundred
→ 100 - 25 = 75 → 75 ÷ 100 = 0.75 So the decimal multiplier is 0.75
⇒ Now multiply the price by the decimal multiplier
→ 1800 × 0.75 = 1350
We can see the CD player X is the one that saves the most money
Answer:
Therefore, the CD player X is worth buying, since it only costs 1,200.
CD player X: 1,200
CD player Y: 1,400
CD player Z: 1,350
Step-by-step explanation:
Formula:
discount amount/original price = discount%/100%
For CD player Z:
discount amount = x
original price/regular price = 1,800
discount% = 25%
For CD player Y:
discount amount = x
original price or regular price = 2,000
discount% = 30%
For CD player X:
discount amount = x
original price or regular price = 1,500
discount% = 20%
______________________________
For CD player Z
x/1,800 = 25/100
x ⋅ 100 = 25 ⋅ 1,800
100x = 45,000
100x/100 = 45,000/100
x = 450
For CD player Y
x/2,000 = 30/100
x ⋅ 100 = 30 ⋅ 2,000
100x/100 = 60,000/100
x = 600
For CD player X
x/1,500 = 20/100
x ⋅ 100 = 20 ⋅ 1,500
100x = 30,000
100x/100 = 30,000/100
x = 300
_________________________
Formula:
Sale price = original price - discount
For CD player Z: 1,800 - 450 = 1,350
For CD player Y: 2,000 - 600 = 1,400
For CD player X: 1,500 - 300 = 1,200

a shirt shop order 1500 shirts. People only bought 1275 t-shirts. what percent of the tshirts were not sold
Answer:
0.15
Step-by-step explanation:
The total amount of shirts not sold is 225 shirts. The percent of shirts not sold is 225 divided by the total number of t shirts which is 1500. 225/1500 is 0.15. So 0.15 percent of the shirts were not sold.

The circles at the right are congruent. Which conclusion can you draw?
A. Angle AEB = Angle QUR
B. Angle CED = Angle SUT
C. CD = ST
D. Arc BD = Arc RT
Answer:
C. CD=ST
Step-by-step explanation:
The conclusion we can draw from the given diagram is Angle AEB = Angle QUR. The correct option is A. Angle AEB = Angle QUR
Congruent circlesFrom the question, we are to deduce which of the given options is correct
From the given information, the circles are congruent
Congruent circles have the same or equal radii
As indicated in the diagram,
Arc AB = Arc QR
Since, the radii of the two circles are equal and the arcs (arc AB and arc QR) are as well equal, their central angles must be equal
∴ Angle AEB = Angle QUR
Hence, the conclusion we can draw from the given diagram is Angle AEB = Angle QUR. The correct option is A. Angle AEB = Angle QUR

Answer:
76.275
Step-by-step explanation:
First - the entire circles area is 78.54. [tex]\pi r^{2}[/tex] with r being 5
6 triangles of that size could fit in that circle.
A=3[tex]\sqrt{3}[/tex]/(2) * a2
The area of that would equal 64.95
78.54-64.95 = 13.59
then divide that number by 6
which is 2.265.
Take that number from the original 78.54
78.54-2.265 = 76.275

x+2y=6
please have a mixed fraction for both the y and x answers
Answer:
(1 [tex]\frac{1}{3}[/tex], 2 [tex]\frac{1}{3}[/tex] )
Step-by-step explanation:
Given the 2 equations
7x - y = 7 → (1)
x + 2y = 6 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the y- term
14x - 2y = 14 → (3)
Add (2) and (3) term by term to eliminate y
15x = 20 ( divide both sides by 15 )
x = [tex]\frac{20}{15}[/tex] = [tex]\frac{4}{3}[/tex] = 1 [tex]\frac{1}{3}[/tex]
Substitute this value of x into either of the 2 equations and solve for y
Substituting in (2)
[tex]\frac{4}{3}[/tex] + 2y = 6
2y = 6 - [tex]\frac{4}{3}[/tex] = [tex]\frac{14}{3}[/tex] ( divide both sides by 2 )
y = [tex]\frac{7}{3}[/tex] = 2 [tex]\frac{1}{3}[/tex]

Which of the following is the factored form of the goven equation? 6x² + 2x - 8 = 0
A. 2(3x+4)(x+1) = 0
B. (6x+1)(x-8)=0
C. 2(3x+4)(x-1)=0
Answer:
C
Step-by-step explanation:
6x^2 + 2x - 8
Multiply the (6) to the -(8) to get x^2 by itself.
x^2 + 2x - 48
Solve -
(x-6)(x+8) = x^2 + 2x - 48
However, you must divide out the (6) you multiplied.
(x-6/6) =
(x-1)
(x+8/6) =
(3x + 4)
Therefore, 2(3x + 4)(x-1) is your answer.
EDIT - At the beginning of the equation it is possible to divide (2) out of the equation, this is where the (2) at the end comes from.
