The Burgesses use about 2 gallons of drinking water per day. If each water jug holds 5 gallons , how many jugs of water do they need for a month with 30 days?

Answers

Answer: 12 jugs of water.

Step-by-step explanation:

Let’s first see how many gallons are needed in 30 days.

2 gallons= 1 day

60 gallons= 30 days

60 gallons are needed in one month with 30 days, and 60 divided by 5 is 12. Which means 12 jugs of water is needed.

Answers

Answer:

y ≥ x - 5 fits the criteria. It is not the only applicable line, there are infinite possibilities.

Step-by-step explanation:

The slope of 1 is positive. The y-intercept of -5 means the line will pass through (5,0) via this slope. In this case, both >= and <= (thus a simple equal sine would work too, though not an inequality) qualify within the provided example.

Step-by-step explanation:

The distance formula is used for the purpose.

  d = √((x2 -x1)² +(y2 -y1)²)

__

17. d = √((3-6)² +(1-5)²) = √((-3)² +(-4)²) = √(9+16) = √25 = 5

The distance between the points is 5 units.

18. d = √((-1-7)² +(12-(-3))²) = √(64 +225) = √289 = 17

The distance between the points is 17 units.

Samuel's air conditioning unit stopped working. He has to find a repair company to fix the unit. He decides to compare the costs of two companies based on their service fees and labor costs.
Cool Ar Plus charges a $25 service fee for coming out to the house. They also charge $25 per hour of work that they perform
- Cool Breeze Ar charges a $40 service fee for coming out to the house. They also charge $15 per hour of work that they perform
The system of linear equations shown can be used to represent this situation. In the system of linear equations, h represents the amount time (in hours) It takes the company to perform the work and C
the total cost in dollars) of the air conditioning work performed by the company
25h + 25 = c
15h + 40 = C
- Determine the point in time, in hours, when the two companies cost the same amount of money.

Answers

Answer:

(a) 1.5 hours

(b) They both charge $62.50

Step-by-step explanation:

The given linear equations are:

[tex]25h + 25 = c[/tex] ---- Cool Ar Plus

[tex]15h + 40 = c[/tex] --- Cool Breeze Ar

Solving (a): The time they charge the same amount.

To do this, we equate both equations

[tex]25h + 25 = 15h + 40[/tex]

Collect like terms

[tex]25h - 15h = 40 - 25[/tex]

[tex]10h = 15[/tex]

Divide both sides by 10

[tex]h = 1.5[/tex]

This implies that they charge the same at 1.5 hour

Solving (b): The same amount they charge

To do this, we substitute 1.5 for h in any of the given equations

[tex]25h + 25 = c[/tex]

[tex]25 * 1.5 + 25 = c[/tex]

[tex]62.5 = c[/tex]

[tex]c=62.5[/tex]

This implies that they charge $62.50

Scott works on cars. He charges a $75 repair fee plus $10 per hour. If Dave was charged $100 by Scott to work on his car, then 1) write an equation that represents the hours, h, Scott worked on his car. How many hours did Scott work on Dave's car?

Answers

Answer:

equation: y= 10x + 75

Hours (x)= 2.5 hours

Step-by-step explanation:

y= 10x + 75

100 = 10x + 75

-75            -75

25 = 10x

/10    /10

x = 2.5

Answer:

1). Inequality: 10h + 75 = 100.

2). Scott worked on his car for 2.5 hours.

Show Work:

Finding out The Inequality -

Sign: = (Equal Sign)

Variable: h (h for hours)

Coefficient: $10 per hour

Constant: $75 repair fee

Total: $100 was charged

Inequality: 10h +75 = 100

Figuring out the Inequality

10h +75 = 100

      -75    - 75

         0      25

10/10 = 1     25/10 = 2.5

h = 2.5

Explain:

With the Inequality I made with the Key concepts of the Word problem, I Started to answer the Question. First, I Subtracted 75 from 100 and 75, so I can see the Amount of Money Dave owes Scott without the Repair fee. 75 - 75 = 0, so I crossed it out, and 100 - 75 = 25. Then I bought the 10h down, so I could Divide it so I can get the Variable and the Answer together. So Because 10 was being Multiplied to the Variable h, I Had to do the opposite, so I divided 10÷10, and 25÷10. 10÷10 = 1, so I crossed it out, and 25÷10 = 2.5. So Scott worked on Dave's car for 2 and a half hours.

sales?
OD

Answers

Answer:

Break-even point in units= 4,400

Step-by-step explanation:

Giving the following information:

Fixed costs= $49,500

Unitary variable cost= $12

Selling price= $23.25

We need to calculate the level of sales that will result in a net profit of zero. We need to use the break-even formula:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 49,500 / (23.25 - 12)

Break-even point in units= 4,400

You are trying to find the area of a deck that is surrounding a rectangular pool. The length of the deck is 2x + 1 and the width is 5x + 2. The pool is a square with sides of 2x. Write a Polynomial that represents the area of ONLY the deck

Answers

Answer:

6x² + 9x + 2

Step-by-step explanation:

The pool is a square with a side length of 2x.

The area of the pool = length * length = 2x * 2x = 4x²

The area of the deck surrounding the pool has length of 2x + 1 and width of 5x + 2. Therefore:

The area of the deck surrounding the pool = length * width = (2x + 1)(5x + 2) = 10x² + 4x + 5x + 2 = 10x² + 9x + 2

Area of the deck only = area of the deck surrounding the pool - area of pool =  (10x² + 9x + 2) - 4x²

Area of the deck only = 6x² + 9x + 2

Joseph bought a 2 pound bag of coffee for $14.95. What is the price per ounce?

Answers

Answer:

0.46 or 0.47

Step-by-step explanation:

A pound is 16 ounces

16 x 2 = 32

14.95 ÷ 32 = 0.4671875

Since cents only goes to the top ten, depending on the question, it will either be 0.46 or rounded to 0.47

The required price per ounce of coffee would be $0.47 per ounce.

What is the division operation?

In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings.

For example 4/2 = 2

To calculate the price per ounce.

We have to divide the cost of the bag of coffee by the number of ounces it contains.

As per the given question, the required solution would be as:

There are 16 ounces in a pound, so the 2-pound bag of coffee contains :

⇒ 2 × 16 = 32 ounces.

To find the price per ounce, divide the price of the bag of coffee by the number of ounces it contains:

⇒ $14.95 / 32 ounces

Apply the division operation, and we get

⇒ $0.47 per ounce.

Therefore, the price per ounce of coffee would be $0.47.
