A dilation is a nonrigid transformation that can produce enlarged or reduced images from a given pre-image. How do you know that

Marat540 [252]

A dilation can elongate or diminish a figure. It can create an image the same as the original by using a scale factor. The scale factor of a dilation is the ratio of corresponding side lengths. To dilate a polygon, multiply the coordinates of each vertex by the scale factor k and connect the vertices.

AleksandrR [38]

<u>Answer:</u>

Below!

<u>Step-by step explanation:</u>

<u>We know that:</u>

400 + 850 + m = 1500

<u>Solution of Question A:</u>

<u>Percent of children: Total children/Total attendance</u>

=> 400/1500
=> 4/15
=> 0.27 (Rounded to nearest hundredth)
=> 0.27 x 100
=> 27%

<u>Hence, the percent of children is about 27%.</u>

<u>Solution of Question B:</u>

<u>Percent of women: Total women/Total attendance</u>

=> 850/1500
=> 85/150
=> 17/30
=> 17/30 x 100
=> 17/3 x 10
=> 170/3
=> 56.67%

<u>Hence, the percent of women is 56.67%.</u>

<u>Solution of Question C:</u>

400 + 850 + m = 1500
=> 1250 + m = 1500
=> m = 1500 - 1250
=> m = 250

<u>Percent of men: Total men/Total attendance</u>

=> 250/1500
=> 1/6
=> 0.17 (Rounded to nearest hundredth)
=> 0.17 x 100
=> 17%

<u>Hence, the percent of men is about 17%</u>

Hoped this helped.

6. A pizza's original price is $11. It is on sale for $9.25. What percent off is it?

wolverine [178]

Solution:

<u>We know that:</u>

$Original \ price = \$11$

$Sale \ price = \$9.25$

$\frac{9.25}{11} + \frac{1.75}{11} =100\%$

<u>Simplify the equation to find the percent off:</u>

$\frac{9.25}{11} + \frac{1.75}{11} =100\%$

$84\% + \bold{16\%} = 100\% \space\ \space\ \space\ \ \ \ \ [Rounded]$

This means that the <u>original price</u> has decreased about 16%.
