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 = 

Mass of gasoline = m
Density of gasoline = d = 

Work done to pump the gasoline out of the tank W
Acceleration due to gravity = g 
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


64,717.36 Joule is the total amount of work needed to pump the gasoline out of the tank.
Answer:
The answer to your question is a) 4/12 b) 5/12
Step-by-step explanation:
Data
Lettuce = 1/12
Carrots = 3/12
Corn = 4/12
Red radishes = ?
a)
The total of the garden is 12/12
Red radishes = 12/12 - 1/12 - 3/12 - 4/12
= 12/12 - 8/12
= 4/12
4/12 of the garden are red radishes.
b)
Corn of lettuce = 1/12 + 4/12
= 5/12
5/12 of the garden are corn or lettuce.

Step-by-step explanation:
It is easiest to compare the equations when they are written in the same form.
The first set can be written in slope-intercept form.
y = 2x +7
y = 2x +7 . . . . add 2x
These equations are <em>identical</em>, so have infinitely many solutions.
__
The second set can be written in standard form.
y +4x = -5
y +4x = -10
These equations <em>differ only in their constant</em>, so have no solutions.
__
The third set is already written in slope-intercept form. The equations have <em>different slopes</em>, so have exactly one solution.
