What is the scale factor of the dilation?

Is the dilation an enlargement or a reduction?

Answers

Answers:

Scale Factor = 3/4

This is a reduction

======================================================

Explanation:

Let's focus on the point R(4,4). That's the preimage point for the image of R ' (3,3).

Let k be the scale factor. We multiply this value of k by the x,y coordinates of point R to jump to R '

we have x = 4 jump to 4k which is the x coordinate of point R'

So we set 4k equal to 3 and solve for k to get k = 3/4. The scale factor is 3/4 or 0.75

We have a reduction since the image triangle T'R'S' is smaller compared to the preimage triangle TRS. We can see that we have a reduction by looking at the scale factor. If 0 < k < 1, then we have a reduction. If k > 1, then we have an enlargement instead. So we go with the first option since 0 < 3/4 < 1 or you could say 0 < 0.75 < 1.

Answer:

A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement is a dilation that creates a larger image

Ophelia keeps flour in a cylindrical canister. The capacity of the full canister is 75.36 in^3..When it is filled halfway the flour reaches a height of 3 in. What is the diameter of the canister?

Answers

Answer:

4 (rounded to the nearest whole number)

Step-by-step explanation:

total height = 3 x 2 = 6

Volume = radius^2 * pi * height

75.36= radius^2 * pi * 6

75.36/pi = radius^2 * 6  

23,987833 = radius^2 * 6

23,987833/6 = radius^2

3,997972 = radius^2

radius = 1,999493

diameter = radius x 2 = 1,999493 x 2 = 3,998986

The perimeter of an equilateral triangle is 63 inches. If the length of each side is (4x-3), find the value of x.

Hint: Triangles have 3 sides.

Answers

Equilateral triangle have the same side lengths. Perimeter = sum of all sides
(4x - 3) + (4x - 3) + (4x - 3) = 63
Remove parentheses
4x - 3 + 4x - 3 + 4x - 3 = 63
Combine like terms
12x - 9 = 63
12x = 72, x = 6

Solution: x = 6

Can someone give me a small lesson on nets and surface areas??

Thank you if you can. I really don’t understand.

Answers

Hi!

Here is the definition of a net from www.icoachmath.com:

“Net is a two-dimensional pattern of a three-dimensional figure that can be folded to form the figure. In other words, net is a flattened three-dimensional figure which can be turned into the solid by folding it.”

In the photo is an example of a net of a rectangular prism.

Surface area is the measure of the total area of the surface of a 3D object. For example, if I have a cube, the surface area would be the area of the outside of the cube.

Hope this helped,

Step-by-step explanation:

Answer:

x = -4

Step-by-step explanation:

-9 (1/2x - 3) = 45

Divide both sides by -9

1/2x - 3 = -5

Add 3 to both sides

1/2x = -2

multiply both sides by 2

x = -4

One–third of the product of −8 and 9

One-fifth the product of 1 and −5
Five times the sum of −8 and 4

Answers:

-24
-20
-1

18

Answers

Answer:

down below.

Step-by-step explanation:

One–third of the product of −8 and 9 = -24

-8(9) = -72

-72 / 3 OR -72(1/3) = -24

Half the sum of 8 and −6 = 1

8 + (-6) =2

2 / 2 = 1

Three times the sum of 12 and −6 = 18

12 + (-6) = 6

6 * 3 = 18

One-fifth the product of 1 and −5 = -1

1(-5) = -5

-5/5 = -1

Five times the sum of −8 and 4 = -20

-8 + 4 = -4

-4 * 5 = -20

1. -24
2. 1
3. 18
4. -1
5. -20

the sides of a rectangle are in the ratio 2:5. if the longer side of the rectangle is 25.5 in., what are it's width, perimeter, and area ?

Answers

Answer: The width of the rectangle is 10.2 inches, the perimeter is 71.4 inches,  the area is 260.1 inches.

Step-by-step explanation:

25.5/5=5.1

5.1*2=10.2

The width is 10.2 inches

25.5*2+10.2*2=71.4

The perimeter is 71.4 inches

20.5*10.2=260.1

The area is 260.1

Width=10.2 in. Perimeter=71.4 in. Area=and 260.1 in.

Frodo ran 2 3/5 miles in 7/12 of an hour. How many miles can Frodo run in one full hour?

Answers

To find how many miles he ran, we need to convert 7/12 of an hour to a full hour. To get a full hour, we must multiply 7/12 by 12/7. Knowing this, we need to multiply 2 3/5 miles by 12/7.

2 3/5 * 12/7

This would be

156/35 miles or 4 16/35 miles
