Answer:
1 39/50 hours. This is equivalent to 1.78 hours.
Step-by-step explanation:
The sum of the hours of work and the hours for break gives the work day hour which has been given as 8 hours.
Furthermore, given that the break time is 22 1/4%, the number of hours for break
= 22 1/4% × 8 hours
= 89/400 × 8
= 1 39/50 hours
Answer:
x = -5
y = -5
Step-by-step explanation:
If you multiply the top equation by negative 2, you can add it to the bottom equation and cancel out the x:
-2(-x + 5y = -20) --> 2x - 10y = 40
Add this to the bottom equation top to bottom:
2x - 10y = 40
-2x + 4y = -10
You get:
-6y = 30
Then solve for y:
y = -5
Plug this back in for either equation and solve for x:
-x + 5(-5) = -20
-x -25 = -20
-x = 5
x = -5
Your answers are:
x = -5
y = -5
Step-by-step explanation:
Work done = Force × displacement
= 350 × 40
=14000J
Answer:
It would be $870 because you have to add 315+555=870
