Answer:
The second 4 wheeler gets better mileage
Step-by-step explanation:
First 4 wheeler:
52mi - 5gal
Second 4 wheeler:
21mi - 2 gal
To compare we have to make sure everything is equal so,
5÷2 = 2.5
so,
second 4 wheeler:
21*2.5=52.5 , 2*2.5=5
52.5mi - 5gal
52<52.5
Given:
![PQRS\sim TUVW](https://tex.z-dn.net/?f=PQRS%5Csim%20TUVW)
In the given figure, PS=x, RS=35, UV=20, VW=25 and TW=15
To find:
The scale factor from PQRS to TUVW.
Solution:
We have,
![PQRS\sim TUVW](https://tex.z-dn.net/?f=PQRS%5Csim%20TUVW)
We know that the corresponding sides of similar figures are proportional. The scale factor is the ratio of one side of image and corresponding side of preimage.
The scale factor is:
![k=\dfrac{VW}{RS}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7BVW%7D%7BRS%7D)
![k=\dfrac{25}{35}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B25%7D%7B35%7D)
![k=\dfrac{5}{7}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B5%7D%7B7%7D)
Therefore, the scale factor from PQRS to TUVW is
.
