Answer:
Step-by-step explanation:
I do believe it is -1 1/2 because I chose two points on the graph (0, 300) and (150, 200). To find slope you need to plug it into an equation, which in this case looks like, (150-0)/(200-300) which then goes to 150/-100, which then simplifies to 15/-10, and then it converts to -1 1/2.
We know that
[area of larger triangle]=[scale factor]²*[area of smaller triangle]
[scale factor]=√[area of larger triangle/area of smaller triangle]
[scale factor]=√[49/16]-----> 7/4
Part A) <span>what is the ratio of the corresponding side lengths?
the ratio </span>of the corresponding side lengths is equals to the scale factor
the answer Part A) is
the ratio of the corresponding side lengths is 7/4
part B)what is the ratio of the perimeters?
the ratio of the perimeters is equals to the scale factor
the answer Part B) is
the ratio of the perimeters is 7/4
Answer:

Step-by-step explanation:
She would have to weigh the fake coins and another bag of real coins to spot a difference, and then she would need to check another bag to see which was correct. Maybe thats right.
