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)

The area of a soccer field is 56 square yards. The length of one side of the field is 8 yards. What is the width of the field?

Answers

Answer:

7

Step-by-step explanation:

you divide 56 by 8 and you get 7

Width of the field is 7 yards

Given that;

Area of soccer field = 56 square yard

Length of one side = 8 yards

Find:

Width of the field

Computation:

Area of soccer field = Area of rectangle

So,

Area of soccer field = [Length of one side][Width of the field]

56 = [8][Width of the field]

Width of the field = 56 / 8

Width of the field = 7 yards

HURRY PLEASE HELP Caitlin wants to collect toys to donate to a local shelter. Her goal is to collect at least 300 toys. On Monday she collects 40 toys. On Tuesday she collects twice as many as on Monday. On Wednesday she collects three times as many as Monday. Which inequality represents the total number of toys Caitlin must collect on Thursday, x, to reach or exceed her goal of 300 toys?

Answers

Answer:

300 ≥ 40 + 80 + 120 + x

x ≥ 60

Step-by-step explanation:

Monday = 40 toys

Tuesday = 2(40) = 80 toys

Wednesday = 3(40) = 120 toys

Thursday = x toys

At least means ≥

300 ≥ 40 + 80 + 120 + x

300 ≥ 240 + x

300 - 240 ≥ x

60 ≥ x

x ≥ 60

The measures of the angles of a triangle are shown in the figure below. Solve for x.

Answers

Answer:

ok, so, since the angles in a traingle all sum up to 180°, that would make:

36°+61°+(4x-17)°=180°

We simplify it:

95°+(4x-17)°=180°

Then, we subtract 95° on both sides:

95°+(4x-17)°=180°

-95°               -95°

Then we get:

4x-17°=85

We add 17° on both sides

4x-17°=85

   +17°  +17°

And we get:

4x=102°

Divide 4 on both sides...

4x=102°

The correct question is:

Find ∠QPR.

Answer:

[tex]\angle QPR = 39[/tex]

Step-by-step explanation:

From the attached figure:

[tex]QPS = QPR + RPS[/tex]

This gives:

[tex]88 = 8x + 15 + 5x + 34[/tex]

Collect like terms

[tex]88 - 15 - 34 = 8x + 5x[/tex]

[tex]39 = 13x[/tex]

A rectangular prism with a volume of 4 cubic units is filled with cubes with side lengths of \dfrac13 3 1 ​ start fraction, 1, divided by, 3, end fraction unit. How many \dfrac13 3 1 ​ start fraction, 1, divided by, 3, end fraction unit cubes does it take to fill the prism?

Answers

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
