What is the name of the amount of useful energy you get from a system?
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
The ratio of useful work output to work input is a measure of?
Efficiency
How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
How is energy efficiency determined?
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
How is the efficiency of a compound machine calculated?
The efficiency of a machine is found by dividing the amount of work done by a machine by the amount of energy used by a machine. The answer is then multiplied by 100 to give a percentage.

What is the relationship between an input work and useful output work?
The relationship between input work and useful output work can be represented by efficiency. Efficiency is the ratio of useful output work to input work. A higher efficiency indicates that a larger proportion of the input work is converted into useful output work, while a lower efficiency suggests that more of the input work is wasted or converted into non-useful forms.

That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
What is efficiency and how is it calculated?
The efficiency is output divided by input.
How is energy efficiency determined?
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
How is the efficiency of a machine calculated?
Efficiency = useful output power / input power

What the measure of the ratio of useful work output to work input?
Efficiency
What is the measure of how much useful work a machine puts out compared to the amount of work put into it?
That is called the efficiency, and it is a number between 0 and 1 (or 0% and 100%). It is obtained by dividing output power / input power.
Total energy input equals equals the useful energy output plus?
Efficiency = ( useful energy output / total energy input ) x 100
