Answer:

Step-by-step explanation:
The similarity ratio is the ratio of corresponding sides, image to original
ratio =
=
=
( = 1.2 )
The answer to the question is 28
but if you want negative, then its -28
There are 72 tokens with Riley and 63 tokens with Erik
<em><u>Solution:</u></em>
Riley and Erik have earned a total of 135 tokens to buy items in the school store
Total number of tokens = 135
The ratio of the number of tokens that Riley had to the number of tokens that Erik has is 8 to 7
Number of tokens with Riley : Number of tokens with Erik = 8 : 7
Let the number of tokens with Riley be 8x
Let the number of tokens with Erik be 7x
Since, Total number of tokens = 135
number of tokens with Riley + number of tokens with Erik = 135
8x + 7x = 135
15x = 135
x = 9
Therefore,
Number of tokens with Riley = 8x = 8(9) = 72
Number of tokens with Erik = 7x = 7(9) = 63
Thus there are 72 tokens with Riley and 63 tokens with Erik

Determine the dilation rule
Using AB and A'B' as points of references;


The dilation factor (k) is calculated as:

This gives:

Factorize


Hence, the scale factor is 2.5
The dilation rule is:



A)
C= 200+10N
10 X 50=500
C=200+500=700

B)
Duncan may have rounded up for both, giving hims higher estimate.
