Just divide the useful work done (the 90J) by the input work. If you want the result in percent, multiply by 100.

How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
The output work of a machine compared to the input work is?
That is called the machine's efficiency.
What is the term for the comparison of input and output work of a machine?
Sounds like you are asking about "mechanical advantage"...
What is the ability of a machine to convert input work into output work?
Efficiency
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.
How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
What of the machine compares the output work to the input work and is expressed as a percent?
That's the machine's "efficiency".
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
The output work of a machine compared to it input work is the of the machine?
Output(input), or O(i)
The ratio of output compaired to in input?
It is the efficiency of a machine.
If the output work of a simple machine equals the input work the machine is said to have efficiency.?
In that case, the efficiency is said to be 1 - or equivalently, 100%.
What is efficiency and how is it calculated?
The efficiency is output divided by input.
How is the efficiency of a machine calculated?
Efficiency = useful output power / input power
How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
The output work of a machine compared to the input work is?
That is called the machine's efficiency.
The work output of a machine divided by the work input is the?
efficiency.
Is the efficiency of a machine calculated by the ratio or by the product?
efficiency is a product of the input versus the output
