A gas station stores its gasoline in a tank under the ground. The tank is a cylinder lying horizontally on its side. (In other w

hoa [83]

Answer:

64,717.36 Joule is the total amount of work needed to pump the gasoline out of the tank.

Step-by-step explanation:

Volume of cylinder = V

Radius of cylinder = r = 0.5 m

Height of the cylinder = 5 m

Volume of cylinder = $\pi r^2h$

$V=3.14\times (0.5 m)^2\times 5 =3.925 m^3$

Mass of gasoline = m

Density of gasoline = d = $673 kg/m^3$

$m=d\times V=673 kg/m^3\times 3.925 m^3=2,641.525 kg$

Work done to pump the gasoline out of the tank W

Acceleration due to gravity = g $.8 m/s^2$

The center of gravity of fuel in fully filled tank will be centre so, the value of h = 2 m + 0.5 m = 2.5 m

$W =m\times g\times h$

$W=2,641.525 kg\times 9.8 m/s^2\times 2.5 m=64,717.36 J$

64,717.36 Joule is the total amount of work needed to pump the gasoline out of the tank.

A fossil is 254 millimeters long. How many meters long is the fossil? Enter your answer, as a decimal, in the box.

Mariana [72]

1000milimeter=1meter
divide both sides by 1000
1mm=1/1000m
times both sides by 254
254mm=254/1000m
254mm=25.4/100m
254mm=2.54/10m
254mm=0.254/1m
254mm=0.254m

it is 0.254 meters

Answer and Step-by-step explanation:

The answer is H.

$f(x) = \frac{1}{3} (4)^x$

When 4 is brought to the power of a number it gets multiplied to the numerator of 1/3. When inputting those numbers for x in this function, the result is what is shown on the table, meaning the function is correct.
