The equation for the volume of a cylinder is r^2 * h * π = V

(2)^2 * 5 * 3.14 = V
4 * 5 * 3.14 = V
20 * 3.14 = V

V = 62.8

Answer: the cost per unit of gas is $0.38

Step-by-step explanation:

Let x represent the cost per unit of electricity.

Let y represent the cost per unit of gas.

During one month, a homeowner used 600 units of electricity and 100 units of gas for a total cost of $344. It means that

600x + 100y = 344- - - - - - - - - -1

The next month, 400 units of electricity and 250 units of gas were used for a total cost of $299.

It means that

400x + 250y = 299- - - - - - - - - -1

Multiplying equation 1 by 400 and equation 2 by 600, it becomes

240000x + 40000y = 137600

240000x + 150000y = 179400

Subtracting, it becomes

- 110000y = - 41800

y = - 41800/- 110000

y = 0.38

Substituting y = 0.38 into equation 1, it becomes

600x + 100 × 0.38 = 344

600x + 38 = 344

600x = 344 - 38 = 306

x = 306/600

x = 0.51

Help easy question!!
LenKa [72]

When you look at the x = 0 and y = -2, that is the y-intercept since the x = 0.

Then when you look at the second one, it goes right one and up four.

As rise over run, it would be 4 / 1 or simply 4.

The slope is 4 and the y-intercept is -2

Plug it in the equation: y = mx + b. M is the slope and B is the y-intercept.

y = 4x -2

Divide a salad with six friends, 1/3 is missing, how much does each person get?
Talja [164]
Each friend gets 1/9. If you have 1 salad and 1/3 is missing that leaves you with 2/3, you have 6 friends and I am assuming they each get an equal amount so 2/3 equals 4/6, 4/6 equals 6/9, there are 6 people, they each get 1/9.
