Answer:
acute triangle
Step-by-step explanation:
I set up fractions based on quarter hours.
I hope this helps.
The side length has to be between 2 (=9-7) and 16 (=9+7). In both these corner cases the triangle will have collapsed to a line.

Answer:
We are given 5 footballs and 9 baseballs. Therefore, the ratio would be 5:9, or 5/9 as the footballs would come first, then the baseballs.
Total: 54
Boys: 36
Girls: x
54 - 36 = x
x = 18
There would be 18 girls at the swim meet
