Answer:
work output is always less than work input - the ratio is less than 1.
Step-by-step explanation:
This principle comes from the fact that a machine or system cannot produce more work than is supplied to it, because this would violate the energy conservation law (work is a type of mechanical energy).
In theoretical machines called "ideal machines" the input work is the same as the output work, but these machines are only theoretical because in real applications there is always some type of energy loss, either in heat produced by a machine or processes for its operation, for this reason the output work is always less than the input work.
Regarding the ratio work output to work input:
WO/WI<1
because work input WI is always greater than work output WO.
Answer:
She can paint <u>6 rooms</u>.
Step-by-step explanation:
Given:
Maya decided to paint some of the rooms in her hotel. She found out that a room required 3/2 cans of paint.
If Maya buys 9 cans of paint.
Now, to find the rooms she can paint.
So, we use unitary method to get the number of rooms:
If, 
cans of paint is needed to paint 1 room.
Then, 1 can of paint is needed to paint = 
room.
Thus, 9 cans of paint is needed to paint = 
Therefore, she can paint 6 rooms.
Eg: 24936
Place value of 4 is 4x10 raised to the power of 3 or 4000
