The fraction that should be removed is 1/5.
<h3>How to calculate the fraction?</h3>
It should be noted that from the information, 40% of the coins are 20-cent coins and the rest are 50-cent coins. Those that are 50 cent will be:
= 100 - 40%
= 60%
The fraction that's should be removed will be:
= 2/5 - x = 1/5
x = 2/5 - 1/5
x = 1/5
The fraction that should be removed is 1/5.

We will be using the formula in looking for the volume of the cylinder which is
V = πr²h
where:
r = radius
h = height
V = volume
but in the problem V and r have values already:
r = 8
V = 4019.2
plug this in the volume equation:
V = πr²h
= 4019.2 = π* 8² * h
= 4019.2 = 64πh
= 4019.2 / 64π = h
so the answer is: h = 4019.2 /201.06193
= 19.99 is the height of the cylinder.

Answer:
3 Credit Courses = 37
4 Credit Courses = 11
Step-by-step explanation:
1. Set up 2 equations:
3x + 4y = 155
x + y = 48
2. Simplify the second expression for x by subtracting y from both sides
x = 48 - y
3. Substitute 48 - y for x
3(48-y) + 4y = 155
4. Simplify the expression by multiplying by 3
144 - 3y +4y = 155
5. Subtract 144 from both sides and subtract 3y from 4y
y = 11 = 4 Credit Courses
6. Substitute y for equation 2
x = 48-11
7. solve for x
x = 37 = 3 Credit Courses
