What is dilation?
Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor.
What is image?The new figure obtained after dilation is called image.
What is scale factor?Scale factor is the ratio of the sizes of the original figure with the dilated figure.
Scale factor formula[tex]scale factor = \frac{dimension of new shape }{dimension of original shape}[/tex]
According to the given question
Volume of solid = 6 cubic units
Surface area of solid = 22 square units
volume of image = 48 cubic units
therefore,
ratio of volumes = ratio of lengths
[tex]\frac{48}{6}[/tex] [tex]=8:1[/tex]
⇒ratio of sides = [tex]\sqrt[3]{8} :\sqrt[3]{1}[/tex]
⇒ ratio of sides = 2 : 1
Ratio of surface area of solid and image = square of ratio of sides = 4:1
⇒[tex]\frac{surface area of image }{surface area of solid} = \frac{4}{1}[/tex]
⇒[tex]\frac{surface area of image }{22} = \frac{4}{1}[/tex]
⇒ surface area of image = 4×21
⇒ surface area of image = 81square units.

Angles DEF and PQR are supplementary. Which is the value of x? (x-6) (2x+42) A 18 B. 48 C. 132 D. 42
Answer:
x = 48
Step-by-step explanation:
(x - 6)⁰ + ( 2x + 42)⁰ = 180⁰
x - 6⁰ + 2x + 42⁰ = 180⁰
x + 2x - 6⁰ + 42⁰ = 180⁰
3x + 36⁰ = 180⁰
3x + 36⁰ - 36⁰ = 180⁰ - 36⁰
3x = 144⁰
3x / 3 = 144⁰ / 3
x = 48

Cinderella made many new friends at the castle. After asking her fairy godmother to help, she invited her friends to go on a picnic. There were 36 heads and 104 legs in the group of horses, carriages, and riders. How many horses and how many people were there?
Answer:
104 legs of horses means 26 horses, since you divide them by 4 to get the number of legs (4) per horse. If there are 36 heads and you subtract the 26 of the horses, you get 10 people heads. There were 26 horses and 10 people

Step-by-step explanation:
that's what I did ^^ (in photo)
Answer:
x=56
Step-by-step explanation:
because they are parallel lines, the angle 124 is the same measurement as the angle on the other side of the line with x. (look at the attachment, im bad at explaining with words lol)
then you do 180 - 124 (180 is the angle of a straight line) and you get x.

Select the best equation needed to solve for x; then solve for x:
A. 5x+12=x; x =14
B. 5x+12=x; x=28
C. 5x+12+x=180 ; x=14
D. 5x+12+x=180 ; x=28
Step-by-step explanation:
A. 5x=12x-14
you will simplify the equation to the form, which is simple to understand
5x=12x-14
We move all terms containing x to the left and all other terms to the right.
+5x-12x=-14
We simplify left and right side of the equation.
-7x=-14
We divide both sides of the equation by -7 to get x.
x=2
B. 5B+12=BB=28
you will move all terms to the left:
.5B+12-(BB)=0
you will move all terms containing B to the left, all other terms to the right
.5B-BB=-12

Answer:
Question 8 is 21, Question 9 is 20.
Step-by-step explanation:
Ratios are very easy if you can find a relationship between them. For #8, to get from 2 to 6 is to multiply 3. Then we multiply 7 and 3 to equal 21. This will be equivalent ratios. The next one is the same thing, to get from 6 to 24, we must multiply 4. We know that to make it equivalent we must multiply 5 with 4 which equals 20. Also we can do this with proportions 2/7 = 6/x. We cross multiply which equals 2x=42. We solve it like an algebraic equation which equals 21. We set up proportions for 5/6 = x/24. We cross multiply which equals 6x = 120. We solve this like an algebraic equation which equals to 20.

Complete the following table so that it represents a linear function and determine the rate of change.
Answer:
let's say x1 = y2. for instance, that would mean that for every X, y would go up by 2. That would mean -1x = Y-2 because to get to -1 you have to subtract 1 by 2 because there is still 0 to account for.
so the table would look like this
-3=-6
-1=-2
1=2
3=6
5=10
