Answer:
A) 9
Step-by-step explanation:
No. of hours required: 4×27 = 108
If 6 machines working:
108÷6 = 18 hours
27 - 18 = 9 hours fewer
Power is work done per time and work done is force times distance. The power is found by multiplying the force(20N) and the distance(5m) and dividing the product by the time(5s)
(20*5)/5=20Nm/s OR 20 watts.
Therefore the power needed is 20 watts.
Draw number line from -5 to 10. .number that line.
Then show a point in 9 and -4
I hope that's what you mean from question
