Step-by-step explanation:
20,000 students 50% are accepted so that is 10,000 students of that 10,000 only 25% enroll which is 2,500.
Since it takes 9 metres to make 24 bows, we know that it takes 9 divided by 24 metres to make a bow. That leaves us with the fraction 3/8,
We take that and multiply by the number of bows to create, which is 16,
that gives us an answer of 6m,
OPTION C,
Hope this helps ;)
I agree with the author. By using the metric system we know the exact amount of a medicine we took, whether it's in mg or mL. This way every doctor can prescribe the same amount.
If we were using some other units this may not be the case. For example, british and american inch were different until 1950's.
Example: if you go to a surgery and a doctor needs to cut "1 inch from the left part" it may cause a mistake as this unit is different in different countries. But if he needs to cut "2.5 cm from the left part" he knows exactly where to cut.
Another benefit of using metric system is that it is being used in almost every country in the world.

Answer:
There are 7^20 possibilities fir the people to get off the elevator
Step-by-step explanation:
I am going to assume that some people (but not neccesarily all) get into the elevator in the low level and none at the highest. Since we are looking for the possibilities for the people to get off the elevator, we can assume that everyone get into in the low level, because this case will contain every possible scenario. Each person has 7 possible ways to get off, hence 20 person will have 7 possibilities powered 20 times, hence there are 7^20 possibilities fir the people to get off the elevator.
