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.

The new figure obtained after dilation is called image.

Scale factor is the ratio of the sizes of the original figure with the dilated figure.

[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.

Answer:

y=-9/7x-15/14

Step-by-step explanation:

Slope-intercept form is y=mx+b

The y-coordinate is on one side, and the slope, x-coordinate, and y-intercept are on the other side.

18x+14y+15=0

-15              -15

18x+14y=-15

-18x       -18x

14y=-15-18x

14y=-18x-15

y=-9/7x-15/14

1 cm^3 is equal to 1 mL so the answer would probably be 210 mL

Answer:210 mL

Step-by-step explanation:

The large cube is representing: 16*16*32= 8192cm

And the small cube is representing: 16*6*2= 72cm

length(cm) × width(cm) × height(cm) = cubic centimeters(cm³)

&

length(mm) × width(mm) × height(mm) ÷ 1000 = cubic centimeters(cm³)

So, answer would be 2,712.

2. 23 weeks

3. 11.25/week

4. 3:2

Step-by-step explanation:

1. 45/4 = 11.25. 11.25 x 6 = 67.5

2. 250/11.25 = 22.22 (rounding up would be 23 weeks)

3. 11.25/week

4. 3:2 (just flip the ratio around)

sorry if some are incorrect

Answer:

$67.50

Step-by-step explanation:

What you do is you divide $45 by 4, which is 11.25, which you then mutiply by 6, which equals 67.5

Answer:

y=2

Step-by-step explanation:

Answer:

1=55°

2=125°

4=125°

5=125°

6=55°

7=125°

8=55°

Step-by-step explanation:

7= 125° because a line is 180°, so 55° + angle 7 = 180°, using simple algebra we can subtract 55 from both sides getting angle 7 = 125°

8= 55° because vertical angles are always congruent

4= 125° because all vertical angles are congruent

6= 55° because alternate interior angles are always congruent so angle 6 = 55°

1= 55° because vertical angles are always congruent

2=125°  because alternate interior angles are always congruent so angle 2 = angle 7

5=125° because vertical angles are always congruent

Answer:

Median: 55

First quartile: 26.5

Third quartile: 93

Interquartile range: 66.5

Answer:

55, 26.5, 93, 66.5

Step-by-step explanation:

First put the values in order from least to greatest:

14, 25, 28, 38, 55, 66, 92, 94, 97

The median is the number in the middle of a data set when it's in order from least to greatest. In this case it's 55, because it's in the middle and has 4 values on either side of it.

The first quartile is the median of the values left of the median. There are 4 values, so there won't actually be a middle. So to find the median of the 4 values, find the mean of the middle 2. The median of 14, 25, 28, 38 is 26.5 because it is the mean of 25 and 28.

The third quartile is found the same way but using the values to the right of the median. The median of 66, 92, 94, 97 is 93 because it is the mean of 92 and 94.

The interquartile range is found by subtracting the first quartile from the third. 93 - 26.5 = 66.5

So the interquartile range is 66.5

Answer:

a.) For the Junior Varsity Team, mean would be the appropriate measure of center since the data is symmetric or well-proportioned while we should use standard deviation for getting the measure of spread since it also measures the center and how far the values are from the mean.

b.) For the Varsity Team, the median would be the appropriate measure of the center since the data is skewed left and not evenly distributed so median could be used since it does not account for outliers while we use IQR or interquartile range in measuring the spread of data since IQR does not account for the data that is skewed.
