The gas tank on the back of a tanker truck can be equated to a cylinder with a diameter of 8 feet and a length of 19 feet. A gal
Leokris [45]

9514 1404 393

Answer:

  • driver's tank: 30,427 lb
  • farmer's tank: 12,811 lb

Step-by-step explanation:

The formula for the volume of a cylinder is ...

  V = πr^2·h . . . radius r, height h

The radius of the driver's tank is half its diameter, so is (8 ft)/2 = 4 ft. Then the volume of that tank is ...

  V = π(4 ft)^2·(19 ft) = 304π ft^3

Each cubic foot of gasoline has a mass of ...

  (1728 in^3/ft^3)(0.0262 lb/in^3) = 45.2736 lb/ft^3

Then the total mass in the driver's full tank is ...

  (304π ft^3)(45.2736 lb/ft^3) ≈ 43,238.3 lb

__

The farmer's tank is a scaled-down version of the driver's tank. It's volume will be scaled by the cube of the linear scale factor, so will be (2/3)^3 = 8/27 of the volume of the driver's tank.

The farmer's tank will hold a mass of (43,238.3 lb)(8/27) ≈ 12,811 lb.

The amount remaining in the driver's tank is 43,238 -12,811 = 30,427 lb.

Find the distance between each pair of points.If necessary round to the nearest tenth
Dovator [93]

Answer:

Step-by-step explanation:

22) J(2,-1); K(2,5)

Distance = √(x₂-x₁)² + (y₂-y₁)²

                = √( 2- 2)² + (5 - [-1] )²

                = √0 + (5  + 1 )²

                =√ ( 6 )²   = 6

25) A(0,3) ; B (0,12)

distance =√(0-0)² + (12 - 3 )²

              =√( 9)²  = 9

28) Q(12,-12) ; T(5,12)

distance = √(5 - 12)² + (12 - [-12] )²

              = √( -7)² + (12 + 12] )²

              = √ 49 + (24)²

              = √ 49 + 576

               = √625

                 =25

Why does 20x700=14000 please give details
Butoxors [25]

Answer:

When multiplying zeros, you first remove the zeros.

So,

2 x 7 = 14

Then you add the zeros to the answer.

We had three zeros

So we add three zeros to 14

14,000

Y = −3x <br> x + y = −4<br> Solution system
Verizon [17]

Answer:

Step-by-step explanation:

Y = - 3x. Equation 1

x + y = - 4 equation 2

Putting value of y

x + (-3x) = - 4

x - 3x = - 4

-2x = - 4

x = - 4/-2 = 2

Putting value of x in the equation 1

Y = - 3(2)

Y = - 6
