The question given is incomplete, here is the complete one gotten from google:
A gas station stores its gasoline in a tank under the ground. The tank is a cylinder lying horizontally on its side. (In other words, the tank is not standing vertically on one of its flat ends.) If the radius of the cylinder is 2 meters, its length is 6 meters, and its top is 4 meters under the ground, find the total amount of work needed to pump the gasoline out of the tank. (The density of gasoline is 673 kilograms per cubic meter; use g=9.8m/s^2
Answer:
Work = 2,238,031 Joules
Step-by-step explanation:
Assuming the tank is initially full, and work is needed to be done to make it empty, and get the fuel to the ground level.
The tank center line is the center of gravity of the fuel, and its distance below ground level is 4+ 0.5 m m= 4.5 m.
Fuel mass = π * (2)²*6*673 = 3.142*6*673 = 50,749 Kg
Work = weight*height
= mass*acceleration due to gravity,g*height
=50,749*9.8*4.5 = 2,238,030.9
Work = 2,238,031 Joules
<em>The y-intercept is 1/3</em>
<h2>
Explanation:</h2>
I'll assume the function is the following:
As you can see, this is the equation of a line written in Slope-intercept form. The general rule of writing lines in this form is:
Where is the slope and is the y-intercept, which is the point at which . By comparing our function with the written rule, we can say that the y-intercept is:

Answer:
Function.
Step-by-step explanation:
A relation is a function every x that in your domain only gets assigned to exactly one number in your range.
Basically if you have a set of points and you see that the same x is being used more than once, then it isn't a function (unless for some reason they repeated the same point).
So the x's I see in the order that your points are is 3,1,-1,-2. All of these x's are different so it is a function.
Answer: t = 1.25j
Explanation:
5/4 = 1.25
So 5 is t and 4 is j
=> t/j = 1.25
=> t = 1.25j
Answer:
12 noodles
Step-by-step explanation:
If each child is given x amount of noodles, and there are 276 noodles to split among 23 students, set up the equation as seen below:
276÷23=12
276 noodles divided by 23 children = 12 noodles per child.
