2. Describe how the volume formulas for a cone, cylinder and pyramid derived. What are the similarities between the volume of a cone and pyramid?
3. What is the relationship between mass, density and volume? Provide and example that involves calculating population density.
4. Manufacturers often alter different packages to save money and to grab customers attention. Explain using an example, how changes in the dimensions of common geometric shapes (prisms, cylinders, cones and spheres) will affect the volume of these shapes.
5. The concept of volume is something you experience everyday in your life. Provide a specific example in which you could solve a real-world application using volume
Answer: if a cone and a cylinder have the same base and same height then the volume of the cone is the volume of the cylinder.

What are the slope and the y-intercept of the line T=14N+40
Final answer:
The slope of the line represented by T=14N+40 is 14, and the y-intercept is 40.
Explanation:
The equation T=14N+40 is in the form y=ax+b, where a represents the slope and b represents the y-intercept. In this equation, 14 is the coefficient of N (which takes the role of x in the general form), indicating that the slope of the line is 14. The constant term is 40, indicating that the y-intercept is 40.

Paul will pay for his new car in 36 monthly payments.if his car loan is for $19,061,then about how much paul will pat each month? Round your answer to the nearest cent if necessary.
Paul will pay approximately $529.47 each month for his new car.
Explanation:To calculate how much Paul will pay each month for his new car, we need to divide the total car loan amount by the number of monthly payments. In this case, the car loan is $19,061 and the number of payments is 36. So, the monthly payment can be calculated as:
Monthly payment = Car loan amount / Number of payments
Substituting the given values, we get:
Monthly payment = $19,061 / 36
Running this calculation, we find that Paul will pay approximately $529.47 each month for his new car, rounded to the nearest cent.

The dance committee hired a DJ for the fall dance. The DJ charges $125 per hour plus $55 for an assistant. The committee wants to keep the total cost under $555. What is the maximum amount of hours the DJ will play at the dance?
The maximum amount of hours the DJ will play at the dance is 4 hours.
Explanation:To find the maximum amount of hours the DJ will play at the dance, we need to set up an inequality. Let x represent the number of hours the DJ will play. The total cost is given by $125 per hour plus $55 for an assistant, so the cost function is C(x) = 125x + 55. We want the total cost to be less than or equal to $555, so the inequality is 125x + 55 ≤ 555.
To solve this inequality, we need to isolate x. First, subtract 55 from both sides to get 125x ≤ 500. Then, divide both sides by 125 to get x ≤ 4. Therefore, the maximum amount of hours the DJ will play at the dance is 4 hours.

Which equation shows y = − 12x +4 in standard form?
A. x + 2y = 8
B. 2x + y = 8
C. x + 2y = − 8
D. 2x − y = 8
Answer: The equation that shows y=-(1/2)x+4 is standard form is x+2y=8
Option A. x+2y=8
Solution:
y=-(1/2)x+4
Standard form of the equation Ax+By=C, with A, B, and C integer numbers
The coefficient of x is a fraction. To simplify the fraction, let's multiply both sides of the equation by 2:
2y=2 [ -(1/2)x+4]
2y=-2(1/2)x+2(4)
2y=-(2/1)(1/2)x+8
2y=-[(2*1)/(1*2)]x+8
2y=-(2/2)x+8
2y=-1x+8
2y=-x+8
The two variables must be on the left of the equation, then adding x both sides of the equation:
2y+x=-x+8+x
x+2y=8

Applying the distance formula, the perimeter of the polygon that has the given vertices is calculated as: 32 units.
Recall:
Perimeter of a polygon is the sum of all its sides.Distance between two vertices having coordinates can be calculated using the distance formula given as: [tex]d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex]Assume the vertices of the polygon are named as:
A(3, 2) B(3, 9)C(7, 12)D(11, 9)E(11, 2)Perimeter of the polygon = AB + BC + CD + DE + AE
Find the distance between A(3, 2) and B(3, 9) using the distance formula:[tex]AB = \sqrt{(9 - 2)^2 + (3 - 3)^2}\\\\AB = \sqrt{7^2 + 0^2} \\\\AB = \sqrt{49} \\\\\mathbf{AB = 7}[/tex]
Find the distance between B(3, 9) and C(7, 12) using the distance formula:[tex]BC = \sqrt{(12 - 9)^2 + (7 - 3)^2}\\\\BC = \sqrt{3^2 + 4^2} \\\\BC = \sqrt{25} \\\\\mathbf{BC = 5}[/tex]
Find the distance between C(7, 12) and D(11, 9) using the distance formula:[tex]CD = \sqrt{(9 - 12)^2 + (11 - 7)^2}\\\\CD = \sqrt{-3^2 + 4^2} \\\\CD = \sqrt{25} \\\\\mathbf{CD = 5}[/tex]
Find the distance between D(11, 9) and E(11, 2) using the distance formula:[tex]DE = \sqrt{(2 - 9)^2 + (11 - 11)^2}\\\\DE = \sqrt{-7^2 + 0^2} \\\\DE = \sqrt{49} \\\\\mathbf{DE = 7}[/tex]
Find the distance between A(3, 2) and E(11, 2) using the distance formula:[tex]AE = \sqrt{(2 - 2)^2 + (11 - 3)^2}\\\\AE = \sqrt{0^2 + 8^2} \\\\AE = \sqrt{64} \\\\\mathbf{AE = 8}[/tex]
Perimeter of the polygon = 7 + 5 + 5 + 7 + 8 = 32 units.

$12.5 money do you save by using the spray gun on a paint job that involves painting 40 m²
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A painter is paid per hour: 11 dollars
Paint with a roller in this time: 8 m²
it takes 1/2 an hour for the painter to clean up after using the roller,
Renting a spray gun costs 5 dollars for each hour of use, and the painter can paint 20 m² per hour with the spray gun.
it takes one hour for the painter to clean up after using the Spray.
We have to calculate how much we have to pay the painter for her time and you must also pay for renting the spray gun for the total amount of time (including clean up) the spray gun was needed. and how much the spray gun on a paint job that involves painting 40 m^2.
Roller
40m²/8m²=5 hrs
5hr to paint with roller.
Total time =5+0.5=5.5hrs
Amount paid=5.5×11=$60.5
40m²/20m²=2 hrs
2 hr to paint with roller.
Total time 2+1=3hr
Amount 3×11+5(3)=$33+15=$48
The saving by using the spray gun on a paint job that involves painting 40 m².
60.5-48=$12.5
