Answer:

16\ ft

Step-by-step explanation:

To find how much weatherstripping will Mike need, calculate the perimeter of the window

so

The perimeter of a rectangular shape is equal to

P=2(b+h)

we have that

b=3.5\ ft, h=4.5\ ft

erica [24]

Answer:

what was paid exactly per student as entrance fee is $6.25

Step-by-step explanation:

In this question, we are told that some kids went to an excursion with their teachers and paid a certain total bill. we now need to know the amount paid per child as the entrance fee to the zoo.

Firstly, we need to subtract the amount paid by the teachers so we know exactly how much was spent on the students entrance fee alone.

subtracting the $5 from the total we have $530 - $5 = $525

Now to know what was paid as entrance fee per student, we simply divide this by the total number of students. That will be 525/84 = $6.25

This means that what was paid exactly per student as entrance fee is $6.25
