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).

Points J, K and L are collinear with J between L and K. If KJ = 2x-3, LJ= 4x-8, solve for x:
notsponge [240]

Your question is incomplete, here is the complete form.

Points J, K and L are collinear with J between L and K.  If KJ = 2x - 3, LK = 9x + 7 and LJ = 4x - 8,  solve for x:

Answer:

The value of x is -6 ⇒ B

Step-by-step explanation:

∵ J, K, and L are collinear

→ That means they form a straight segment

∵ J is between K and L

→ That means J divides LK into two segments KJ and LJ

∴ LK = KJ + LJ

∵ LK = 9x + 7

∵ KJ = 2x - 3

∵ LJ = 4x - 8

→ Substitute them in the equation above

∴ 9x + 7 = (2x - 3) + (4x - 8)

→ Add the like terms in the right side

∵ 9x + 7 = (2x + 4x) + (-3 - 8)

∴ 9x + 7 = 6x + -11

∴ 9x + 7 = 6x - 11

→ Subtract 7 from both sides

∵ 9x + 7 - 7 = 6x - 11 - 7

∴ 9x = 6x - 18

→ Subtract 6x from both sides

∵ 9x - 6x = 6x - 6x - 18

∴ 3x = -18

→ Divide both sides by 3

∵ \frac{3x}{3}=\frac{-18}{3}

∴ x = -6

∴ The value of x is -6
