Answer:
25 questions
Step-by-step explanation:
At a math competition 2 students can answer 40 questions in 1 hour.
Therefore, 1 student can answer in 1 hour = 
= 20 questions
5 students can answer in 1 hour = 20 × 5 = 100 questions
60 minutes = 1 hour
15 minutes =
= 0.25 hours
5 students can answer in 0.25 hours = 100 × 0.25
= 25 questions
5 students could answer 25 questions in 15 minutes.
2/3 would be converted to 4/6 by multiplying the numerator and denominator by 2.
then you can add 4/6 + 1/6 to get 5/6

Formula for finding volume of a cylinder is V=pi r^2h, substitute h for the height and r for radius. V=pi 3^2 2
All linear dimensions of similar figures are in the same ratio.
The perimeters are also in the ratio of 5 to 4.
