Answer:
G. Carla, Brenda, Marci, Susan
Step-by-step explanation:
The time given for all participants are in decimals except for that of Marci and Carla which are given in the form of mixed fractions.
Convert the mixed fractions into decimals, then compare the figures together to do the ranking.
Marci = ![46\frac{49}{50} = \frac{2,349}{50} = 46.98](https://tex.z-dn.net/?f=%2046%5Cfrac%7B49%7D%7B50%7D%20%3D%20%5Cfrac%7B2%2C349%7D%7B50%7D%20%3D%2046.98%20)
Carla = ![46\frac{9}{10} = \frac{469}{10} = 46.9](https://tex.z-dn.net/?f=%2046%5Cfrac%7B9%7D%7B10%7D%20%3D%20%5Cfrac%7B469%7D%7B10%7D%20%3D%2046.9%20)
The first four finishers from the 1st to the 4th are:
1. Carla - 46.9
2. Brenda - 46.97
3. Marci - 46.98
4. Susan - 47.21

Expand brackets:
![\implies V=\pi r^2h-4\pi r^3](https://tex.z-dn.net/?f=%5Cimplies%20V%3D%5Cpi%20r%5E2h-4%5Cpi%20r%5E3)
Factor:
![\implies V=\pi r^2(h-4 r)](https://tex.z-dn.net/?f=%5Cimplies%20V%3D%5Cpi%20r%5E2%28h-4%20r%29)
Hello!
We need to get our number out of 100 to make it a percent. To get 40 to 100, you multiply by 5/2.
This gives us 2.5%
I hope this helps!
