Paul orders 3 different sizes of pizzas. Each pizza is cut into equal-sized slices as described in the table. Put the pizzas in
Elza [17]

The area of a slice from smallest area to largest area is given by:

  1. Pizza 1 (32π in²).
  2. Pizza 2 (32.7π in²).
  3. Pizza 3 (36π in²).

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

The area of a circle can be defined as the total space occupied or region enclosed by a circle within its boundary, and in a two-dimensional plane.

<h3>How to calculate the area of a circle?</h3>

Mathematically, the area of a circle is calculated by using this formula:

Area = πr²

<u>Where:</u>

r is the radius of a circle.

For Pizza 1, we have:

Area = π × 16²

Area = π × 256

Area = 256π in².

Area of a slice = 256π/8

Area of a slice = 32π in².

For Pizza 2, we have:

Area = π × 14²

Area = π × 196

Area = 196π in².

Area of a slice = 196π/6

Area of a slice = 32.7π in².

For Pizza 3, we have:

Area = π × 12²

Area = π × 144

Area = 144π in².

Area of a slice = 144π/4

Area of a slice = 36π in².

In conclusion, we can infer and logically deduce that the area of a slice from smallest area to largest area is given by:

  1. Pizza 1 (32π in²).
  2. Pizza 2 (32.7π in²).
  3. Pizza 3 (36π in²).

The monthly cost of driving a car depends on the number of miles driven. Lynn found that in May her driving cost was $380 for 48
andrezito [222]

Answer:

y=0.2x+284

Step-by-step explanation:

Let  x be the distance driven, d-distance and C our constant.

Our information can be presented as:

y=mx+c\\\\450=830x+C\ \ \ \ \ \ \ \ \ eqtn 1\\\\380=480x+C\ \ \ \ \ \ \ \ \ eqtn 2

#Subtracting equation 2 from 1:

70=350x\\x=0.2

Hence the fixed cost per mile driven,x is $0.20

To find the constant,C we substitute x in any of the equations:

450=830x+C\ \ \ \ \ \ \ X=0.2\\\therefore C=450-830\times0.2\\=284

Now, substituting our values in the linear equation:

y=0.2x+284       #y=cost of driving, x=distance driven

Hence the linear equation for the cost of driving is y+0.2x+284
