The scale factor would be 2, since the image is 2 times bigger than the pre-image.

Hope this helps! :) I did this last year, so this is the correct answer! ;)

Answer: The answer is 2.

Step-by-step explanation: We are given to find the scale factor for the dilation of a triangle shown in the figure.

The triangle ABC is dilated to form the triangle A'B'C'.

To find the scale factor, we need to divide the length of one side of the dilated triangle A'B'C' by the length of the corresponding side of the original triangle ABC.

From the figure, we note that

AB = 5 units and A'B' = 10 units.

Therefore, the scale factor will be

$S_f=\dfrac{A'B'}{AB}=\dfrac{10}{5}=2.$

Thus, the answer is 2.

100(whole class is 100%) / 6060(number of students total) = any random student chance
0.0165
A) for democrats multiply chance of any random student with number of democrats
0.0165×4040=66.66666...
B) for business majors, multiply that chance with number of business majors
0.0165×1010=16.66666...
C) for both business major and democrat multiply chance with numbers of students who are both
0.0165×33=0.544...

Jaya forgets how to write numbers in expanded form. Explain the steps to her using the number 13.652 as an example, and then wri

Amanda [17]

In the expanded form the digits of the number are split into each of the individual digits with their place value and written in expanded form. The example of standard form of a number is 4,982 and the same number can be written in expanded form as 4 × 1000 + 9 × 100 + 8 × 10 + 2 × 1 = 4000 + 900 + 80 + 2.
