Answer:
$9,840
Step-by-step explanation:
Let the money earned from college be 'x'.
Given:
Total money earned from the two jobs = $50,450
Money earned at the store = 1250 + 4(Money earned at college)
∴ Money earned at the store =
Now, total money earned by Erica is the sum of money earned at store and college. Therefore,
Total money = Money at store + Money at college
Therefore, the money earned by Erica from her job at the college is $9,840.
*Correct Question:
Based on the similar triangles shown below, Theodore claims that ∆TUV is transformed to ∆WXY with a scale factor of 3/2. Is Theodore correct?
A. Yes, the triangles are similar with a scale factor of 3/2.
B. No, the triangles are similar with a scale factor of 2/1.
C. No, the triangles are similar with a scale factor of 2/3.
D. No, the triangles are similar with a scale factor of 4/3.
Answer:
C. No, the triangles are similar with a scale factor of 2/3.
Step-by-step explanation:
∆TUV is the original triangle. After transformation, the size reduced to give us ∆WXY. This means ∆TUV was reduced by a scale factor to give ∆WXY. The scale factor should be a fraction, suggesting, the original size of the ∆ was reduced upon transformation.
Thus, the ratio of their corresponding sides = the scale factor.
This is:
If you multiply the side length of ∆TUV by ⅔, you'd get side length of ∆WXY.
So, Theodore is wrong.
