What is the scale factor of the dilation?
Is the dilation an enlargement or a reduction?
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

in a coordinate plane what is the difference between (-3 1/2, 4) and (2 1/2)?
Answer:
?
Step-by-step explanation:
By difference I think you mean how far away from? I don't really know what you mean by this but I will try to help.
1/2-4=-3 1/2
2-(-3 1/2)=5 1/2
-3 1/2
5 1/2
Above is a fraction.
I hope that I helped. Sorry if it wasn't the answer you were looking for.

Solve the x
-9 (1/2x - 3) = 45
Answer:
=
−
3
6
7
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
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 ?
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.

One–third of the product of −8 and 9
Half the sum of 8 and −6
Three times the sum of 12 and −6
One-fifth the product of 1 and −5
Five times the sum of −8 and 4
Answers:
-24
-20
-1
1
18
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

Answer:
C
Step-by-step explanation:
i did the math
Answer:
C
Step-by-step explanation:
To find an estimation for how many students want each, divide 200 by the 25 students that were surveyed. You get 8, which can be multiplied by each of the meal votes.
So 12 * 8 is 96, which means 96 people likely chose the beef meal. 8 * 8 is 64, which means 64 people likely chose the chicken meal. In answer c, it says that 34 more students want beef than chicken. If you subtract 64 from 96, you get 32.

Can someone give me a small lesson on nets and surface areas??
Thank you if you can. I really don’t understand.
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,

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?
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
