The factors for 2xy - 8x + 5y -20 is ( 2x + 5 ) ( y - 4 ).
Given 2xy - 8x + 5y -20
By writing like terms on one side
2xy - 8x + 5y - 20
By taking common terms outside we get
2x ( y - 4) + 5 ( y - 4)
By taking common terms we get
( 2x + 5 ) ( y - 4 )
Therefore the factors for 2xy - 8x + 5y -20 is ( 2x + 5 ) ( y - 4 )..

Average movie prices in the United States are, in general, lower than in other countries. It would cost $79.31 to buy three tickets in Japan plus two tickets in Switzerland. Three tickets in Switzerland plus two tickets in Japan would cost $75.24. How much does an average movie ticket cost in each of these countries?
The average cost of tickets in Japan and Switzerland are $17.49 and $13.42 respectively.
How to find the average movie ticket in each city?It would cost $79.31 to buy three tickets in Japan plus two tickets in Switzerland.
Three tickets in Switzerland plus two tickets in Japan would cost $75.24.
Therefore,
let
x = cost of Japan tickets
y = cost of Switzerland tickets
Hence,
3x + 2y = 79.31
2x + 3y = 75.24
3x + 2y = 79.31
3x + 4.5y = 112.86
2.5y = 33.55
y = 33.55 / 2.5
y = $13.42
3x + 2(13.42) = 79.31
3x = 79.31 - 26.84
3x = 52.47
x = 52.47 / 3
x = $17.49
Therefore, the average cost of tickets in Japan and Switzerland are $17.49 and $13.42 respectively.

An ice cream waffle cone has a diameter of 8.5cm at the opening, a perpendicular height of 17.8, slant height of 19.73. What is the surface area ofvthe cone to the nearest cm
The surface area of the ice cream waffle cone is found to be 263 square cm.
How to define a cone?A cone is a shape formed by connecting a common point, known as the vertex, to all of the points of a circular base with a set of line segments (that does not contain the vertex).
The height of the cone is the distance from the vertex to the base.A birthday cap with in shape of a cone is one of the simplest real-life examples.Now, as per the given question;
The ice cream waffle is in the shape of the cone.
The diameter if the cone is given as 8.5 cm.
Then, the radius 'r' of the cone will be 8.5/2 = 4.25 cm.
The slat height 'l' if the cone is 19.73 cm.
The formula for finding the surface area is;
SA = πrl
Substituting the values;
SA = π×4.25×19.73
SA = 263.43
SA = 236 cm.
Therefore, the surface area of the ice cream waffle cone is estimated as 236 cm².

Which statement is not used to prove that ΔFGH is similar to ΔFIJ? triangles FGH and FIJ in which point I is between points F and G on segment FG and point J is between points F and H on segment FH Angle F is congruent to itself, due to the reflexive property. Angles FJI and FHG are congruent, due to the corresponding angles postulate. Points F, J, and H are collinear. Segments JI and HG are parallel.
Answer:
Points F, J, and H are collinear
Step-by-step explanation:
just took exam
The statement F, J, and H are collinear is not used to prove that ΔFGH is similar to ΔFIJ.
We have to find out which statement is wrong regarding ΔFGH is similar to ΔFIJ.
Here the statement points F, J, H are collinear are not used to prove the similarity of both triangle because if these three points are collinear than there is no triangle possible and when there is no triangle than how we prove similar to them.
So when F,J and H are collinear than we can't prove similar to both the triangles.
But in all the other points we can prove the similarity of both the triangles.
Hence the statement F, J, and H are collinear is not used to prove that ΔFGH is similar to ΔFIJ.

Use the following formula to calculate the volume:
[tex]\boxed{\mathrm{Volume = length \times width \times height}}[/tex],
where:
• length = 24 in.
• width = [tex]12\frac{1}{2}[/tex] in.
• height = 2 in.
Substituting these values into the formula:
Volume = [tex]24 \times 12\frac{1}{2} \times 2[/tex]
= 600 in³
∴ D. is the correct option.
6.
Here, we can see that the height of the water that Yolanda will put in the tank is 5 inches less than 18 in. because the sand takes up 2 in. and the gap at the top takes up 3 in.
• height of water = 18 - 3 - 2
= 18 - 5
= 13 in.
• length = 24 in.
• width = [tex]12\frac{1}{2}[/tex] in.
∴ Volume = [tex]24 \times 12\frac{1}{2} \times 13[/tex]
= 3900 in³
∴ The correct option is C.

Answer:
D
Step-by-step explanation:
The coordinates of the point at a ratio of 4/5 for the line AB will be (4,4). The correct option is D.
What is coordinate geometry?
A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that the line AB on the coordinate system is having a ratio of 4/5.
From the given data it is observed that the line AB is distributed in the fraction of 4:5. The point on this fraction has the coordinates ( 4,4).
Therefore, the coordinates of the point at a ratio of 4/5 for the line AB will be (4,4). The correct option is D.

An account with an initial deposit of $6,500 earns 7.25% annual interest, compounded
continuously. How much will the account be worth after 20 years
Answer:
$27,710.24
Step-by-step explanation:
You want to know the value of $6500 earning 7.25% interest compounded continuously for 20 years.
Continuous compoundingThe formula for the amount in an account earning interest at rate r compounded continuously is ...
A = P·e^(rt)
where P is the principal invested at rate r for t years.
Your amount is ...
A = $6500·e^(0.0725·20) = $6500·e^1.45 ≈ $27,710.24
The account will be worth about $27,710.24 after 20 years.

You want to know the area of the library, which is a composite shape.
AreaThe area of a composite shape is found by dividing it into shapes whose areas are easy to find. The area of the shape will be a combination of the areas of the simpler shapes.
The formula for the area of a rectangle is ...
A = LW
Extending the middle horizontal line will divide the figure into two rectangles whose dimensions are given on the figure.
The upper rectangle is 30 ft wide and 5 ft high, so its area is ...
A = (30 ft)(5 ft) = 150 ft²
The lower rectangle is 22 ft wide and 8 ft high, so its area is ...
A = (22 ft)(8 ft) = 176 ft²
The area of the library will be the sum of these two rectangular areas:
library area = 150 ft² +176 ft² = 326 ft²
The library area is 326 square feet.
__
Alternate solution
The area could be considered to be a rectangle that is 30 ft wide by 5+8=13 ft high, with a rectangle 30-22=8 ft wide and 8 ft high removed from the lower left corner. The difference in area between the overall rectangle and the removed rectangle is ...
(30 ft)(13 ft) -(8 ft)(8 ft) = 390 ft² -64 ft² = 326 ft²
The method shown above does not require calculating missing dimensions, so is more straightforward.

Answer:
y = (4/3)x.
or in standard form it is
-4x + 3y = 0.
Step-by-step explanation:
The slope m = (8-4) / (6-3)
= 4/3
Using the point-slope form of a line:
y - y1 = m(x - x1)
We use m = 4/3, x1 = 3 and y1 = 4:
y - 4 = 4/3(x - 3)
Multiply through by 3:
3y - 12 = 4(x - 3)
3y = 4x - 12 + 12
3y = 4x
y = (4/3) x
or in standard form it is
-4x + 3y = 0.
