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:

B.x>19

................

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:

100 - 49 - 9

Step-by-step explanation:

sq root(100) = 10.       sq root(49) = 7        sq root(9) = 3

10-7-3=0!!!!!

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.

Answer:

the answer is C

Step-by-step explanation:

The answer is C.

Because we do not have any tables graphs etc., we can only use the fact that the range is 1

The definition of range is the difference between the largest amount and the smallest amount. In equation form, it should look like this:  

Now lets move to the answer choices:

Answer A. is wrong

If everyone surfed for exactly an hour, the largest amount of time would be 1 hour and the smallest amount of time would also be 1 hour. Put this into the equation and the range would be 0 which is contradicted from the data present

Answer B. is wrong because the range is not the average, the mean is the average. We are looking for the range, not the mean so Answer B. is incorrect.

Answer C. is correct. The range is the difference between the largest and the smallest. In this answer, it tells us that the range is the difference between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour. This follows the term of "Range" and therefore, Answer C. is correct.

Answer D. is incorrect because the range does not have anything to do with quotients.(By the way, a quotient is the result of dividing a dividend with a divisor.) The range is only obtainable with subtraction, not division, so answer D. is incorrect.

[tex] \rm Numbers = 4 \ and \ -3.[/tex]

Step-by-step explanation:

Given :-

And we need to find out the numbers. So let us take ,

According to first condition :-

[tex]\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}[/tex]

Hence the numbers are 4 and -3

Step-by-step explanation:

[tex]integers \: = x \: and \: y \\ then \: x \times y = - 12 ....(1)\\ x + y = 1.....(2) \\ x = 1 - y.....(3) \\ put \: (3 )\: in \: (1) \\ then \: (1 - y) \times y = - 12 \\ y - {y}^{2} + 12 = 0 \\ {y}^{2} - y - 12 = 0 \\ factorise \\ {y}^{2} - 4y + 3y - 12 = 0 \\ y( y - 4) + 3(y - 4) \\ (y - 4)(y + 3) \\ y = 4 \: and \: - 3 \\ thank \: you[/tex]
