Answer:
24 in
Step-by-step explanation:
The volume of a pyramid of base area A and height h is V = (1/3)(A)(h).
It's easiest to solve this for h before plugging in numerical values. Solving for h, we get: 3V = A·h, or
3V
h = -------------
A
With A = 42.5 in² and V = 340 in³, we have
3(340 in³)
h = ---------------- = 24 in
42.5 in²
V = --------------

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?
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.
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.
- Identify the cost of the repairs, in dollars, when the two companies cost the same amount of money,

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
Owen and bella shared a granola bar. Bella ate 1/4 of the granola bar. Owen ate 1/3 of the bar. How much of the granola bar dis owen and bella leave uneaten?
Answer:
5/12
Step-by-step explanation:
You would have to make the fractions equivalent.
Multiply both the numerator 1 and the denominator 4 by 3. You should end up with 3/12. For 1/3 you need to multiply the numerator 1 by 4 and the denominator 3 by 4. You should end up with 4/12. Add 3/12 and 4/12 and you should get 7/12. 7/12 is the amount they ate so you do 12 -7/12 which should get you 5/12.

Answer:
17. 5
18. 17
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.
what is a linear inequality that has (5,0) as a solution, passes through the origin, and has a positive slope?
I will mark whoever answers as a brainliest tysm :)
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.
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?
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.

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing, and variable costs
(such as printing). The one-time fixed costs will total $49,500. The variable costs will be $12 per book. The publisher will sell the finished product to
bookstores at a price of $23.25 per book. How many books must the publisher produce and sell so that the production costs will equal the money from
sales?
OD
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

Answer:
y = 7/4x + 5
Step-by-step explanation:
14x - 8y = 80
-8y = -14x + 80
8y = 14x - 80
y = 7/4x - 10
Slope: 7/4
As long as the slope is 7/4, they will be parallel
Answer:
[tex]\frac{7}{4}[/tex]
Step-by-step explanation:
14x - 8y = 80
- 8y = - 14x + 80
- 4y = - 7x + 40
y = [tex]\frac{7}{4}[/tex] x - 10

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