Answer:
a. 1.25
b . 0.8
Explanation:
This is a question in scale factors
a. The sable factor that takes P to Q
In P, we are having sides 4, 2 and 3
In Q, we are having sides 2.5 and 5
From the diagrams and using the similar sides, we can see that the side length 4 became 5 while the side length 2 became 2.5
So the scale factor would be;
4 * x = 5
or
2 * x = 2.5
Where x is that dilation factor that transformed 4 into 5
Thus, x would be 5/4 or 2.5/2 = 1.25
b. The scale factor that takes Q to P
This is the direct opposite of what we have in the first question.
Here, we want to go from Q to P
To get this, we simply divide what we have in P by what we had in Q
Hence, what we do here is;
2/2.5 or 4/5 = 0.8
