Answer:
The scale factor for the dilation of rectangle ABCD to rectangle MNOP is
⇒ B
Step-by-step explanation:
In similar rectangles, their corresponding dimensions are proportional, which means
=
, where L is the length and W is the width
∵ Rectangle ABCD is similar to rectangle MNOP
∴ Their dimensions are proportional
∵ The dimensions of rectangle ABCD are 6 m, 14 m
∴ L
= 14 and W
= 6
∵ The dimensions of rectangle MNOP are 4.5 m, 10.5 m
∴ L
= 10.5 and W
= 4.5
∵ The rectangle MNOP is the image of rectangle ABCD after dilation
→ To find the scale factor of dilation find the ratio between the
corresponding dimensions in the two rectangles (image/pre-image)
∵
=
= 
∵
=
=
∴ The scale factor for the dilation is
The scale factor for the dilation of rectangle ABCD to rectangle MNOP is

▹ Answer
<em>g = 87</em>
▹ Step-by-Step Explanation
-34 = -2(g - 70)
<u>Divide both sides</u>
17 = g - 70
<u>Rearrange the terms</u>
-g + 17 = 70
<u>Calculate</u>
-g = -87
<u>Change the signs</u>
g = 87
<u>Final Answer</u>
g = 87

Answer:
$9
Explanation:
First, we need to find 70% of the original price of $30 using the following equation:

It means that Emma pays $21 less than the original price. So, she pays:
$30 - $21 = $9
Therefore, the answer is $9
