Answer:
The radius of the cone is 3 units
Step-by-step explanation:
An oblique cone is a kind of slanted cone. It is a figure such that the tip of the cone is not directly over the center of the circular base of the cone.
While the method for calculating the area of an oblique and a right-circular cone is different, the method for calculating the volume is the same
Mathematically, the volume of an oblique cone = 1/3 * pi * r^2 * h
in this question, we have the height and the volume but we want to calculate the radius
substituting the value for the volume, the height and radius( radius is half diameter = 2x/2 = x) we have
18 pi = 1/3 * pi * x^2 * 2x
divide through by pi
18 = 1/3 * 2x * x^2
54 = 2x^3
divide both sides by 2
x^3 = 54/2
x^3 = 27
x = cube root of 27
x = 3 units
This is the length of the radius
Y = 12x - 40
the x variable represents the number of hours Sam works at the airport
the y value represents the amount in dollars that Sam has after paying Daniel
the 12 is the amount in dollars that Sam earns per hr
the 40 is the amount in dollars Sam owes Daniel

Step-by-step explanation:
To determine which ordered pairs are solutions to the equation
Substitute the x and y values into the left side of the equation and if equal to the right side then they are a solution.
(- 1, - 6)
3(- 1) - 4(- 6) = - 3 + 24 = 21 = right side ← thus a solution
(- 3, 3)
3(- 3) - 4(3) = - 9 - 12 = - 21 ≠ 21 ← not a solution
(11, 3)
3(11) - 4(3) = 33 - 12 = 21 = right side ← thus a solution
(7, 0)
3(7) - 4(0) = 21 - 0 = 21 = right side ← thus a solution
The ordered pairs (- 1, - 6), (11, 3), (7, 0) are solutions to the equation
Answer:
18
Step-by-step explanation:
as there are 12 red spheres there are 12*4 red cubes (48) add them ,60.Then 60/2 to find blue shapes ,30, then add the 2 and 3 to make 5 after that do 30/5 = 6 then multiply by 3
To answer this we would need the expressions given.
