5-2.25=x x is what you are able to spend
Answer:
39
Step-by-step explanation:
If 8 out of 21 are WOODWINDS, we can say:
21 - 8 = 13
13 out of 21 ARE NOT woodwinds.
This is the ratio.
Now, there are 63 total instruments. We need to find how many ARE NOT woodwinds. We equate the ratio found (13 out of 21) with total 63 instruments and find "x" [let x be number of instruments that are NOT woodwinds].
Shown below:

Hence, out of 63 instruments, we can say that 39 are not woodwinds
Answer:
Surface Area = 283
Step-by-step explanation:
Radius = 3
Height = 12
Formula for suface area is SA= 2πrh+2πr^2
let "r" be for radius
let "h" be for height
SA=2*π*3*12+2*π*3^2
SA=282.74
round to the nearest ones spot and that will make the surface area = 283
(x-4)^2+(y-0)^2=3^2 is the answer
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
