Answer: d. The helicopter rotor will spin 36,000 times in 1 hour
Step-by-step explanation:
Option A is wrong because in 40 minutes the rotor will spin:
= 40 * 600
= 24,000 times
Option B is wrong because we cannot know the number of times the rotor will spin before being lifted off of the ground with the details given.
Option C is wrong because in 3 hours the rotor will spin:
= 600 * 3 * 60 minutes
= 108,000 times
Option D is correct because in 1 hour the rotor will spin:
= 600 * 1 * 60 mins
= 36,000 times
Answer:
Step-by-step explanation:
Write down what you have for each pizza size.
small: s
Medium: (3/2) s
Large: (5/2) s
The only way I can see to do this is
s = L - M
s = 5/2 s - 3/2 s
s = 2/2 s
This of course is not exactly what you are looking for. There is no explicit formula that will tell you exactly how much dough is in a small pizza.
See the comment below posted by SqdanceFan. He is saying that M/L = (3/2)//(5/2) = 3/5
Also (M)/( S + M) = 3/5
But neither gives you an explicit formula for small, but it is a relationship. The fact that equality is achieved when both are zero is also true, but it does not solve the question. I don't think there's a good answer to this question.
