Complete Question

Question 14

Jabar earns $5 for the first 10 pounds of newspaper he recycles, then $0.25 for each additional pound. Which expression represents the amount he earns for recycling p pounds of newspaper if p > 10?

a. 5+0.25 (p-10)

b. (5 +0.25) P

c. 5 +0.25p

d.5 (10) +0.25p

Answer:

5 (10) +0.25p

Step-by-step explanation:

Let the number of additional pounds = x

Hence:

Jabar earns $5 for the first 10 pounds of newspaper he recycles, then $0.25 for each additional pound.

The statement above is represented as:

$5 × 10 + $0.25 ×p

= 5(10) + 0.25(p)

Therefore, the expression that represents the amount he earns for recycling p pounds of newspaper if p > 10 is written as

5(10) + 0.25(p)

Answer:

108 cubes

Step-by-step explanation:

A rectangular prism with a volume of 4 cubic units is filled with cubes with side lengths of 1/3 . How many 1/3 unit cubes does it take to fill the prism?

Step 1

We find the volume of the cubes

Side length = 1/3 units

Volume of a cube = Side length ³

Hence,

(1/3 units)³ = 1/27 cubic units

Step 2

A rectangular prism with a volume of 4 cubic units.

The number of 1/3 unit cubes that would fill this rectangular mrism is calculated as:

4 cubic units ÷ 1/27 cubic units

= 4 ÷ 1/27

= 4 × 27/1

= 108 cubes

Answer:

X = 18

Step-by-step explanation:

x + 2x + 4x + 5x + 8x =360

20x = 360

20x/20= 360/20

x=18

The value of x in the pentagon angles is 3.6

Pentagon are polygons with five sides.

The exterior sides of the pentagon are given as follows:

Exterior angles formula for polygon is as follows:

where

n = number of sides

Therefore,

x + 2x + 4x + 5x + 8x = 360 / 5

x + 2x + 4x + 5x + 8x = 72

20x = 72

x = 72 / 20

x = 3.6
