12/20 as a percentage = 60
75% = 15 matches out of 20

1/4 of 20 = 5
75% = 20 - 5 / 20
75% = 15 / 20

A cheesecake has equally sized slices. Each slice is a different flavor. The cheesecake has 12 slices.

<h3>What is the area of the circle?</h3>

The area of the circle is defined as the product of the pie and the square of the radius.

The area of the circle = πr²

In order to calculate the total area of the cheesecake, since it's a circle its area is given by:

cheesecake area =  πr²

cheesecake area =  π(10/2)² =  π(5)²

cheesecake area = 25 π square inches

Therefore the number of slices is the ratio of the cheesecake total area by the area of each slice:

The number of slices = 25 π/(25 π/12)

The number of slices = 12

The cheesecake has 12 slices.

Explain whether each equation is a linear equation.
Aleksandr-060686 [28]

Answer:

3. Not linear

4. Linear

Step-by-step explanation:

3. The equation has an exponent on the x. Since x is squared the graph is a parabola. The graph is a curve, not a line, so it is not linear.

4. Both the x and y have no exponent (which is an exponent of 1) The graph will be a line. This is a linear function.
