Answer:
The muscular work completed by four men will be 2400 ft. lbs.
Step-by-step explanation:
See the diagram of the ramp.
Four men carry 20 boxes each up a ramp as shown.
So, 4 men carry total (4 × 20) = 80 boxes up the ramp and each box weighs 5 pounds.
Then, the 4 men carry total (80 × 5) = 400 lb weight up the ramp.
Now, the vertical height of the ramp from the ground level is 6 ft.
Hence, the muscular work completed by four men will be (400 × 6) = 2400 ft. lbs. (Answer)
Answer:
1. 5x-11 = -16 so x= -1
2. 12x -8 = 48 so x=56/12
3. 5x +2 = 13 so. x= -3
4. 7x +11 = 81 so x = 10
5. 3x -2 = -15 so. x= -13/3
6. 5x + 2 = 35 so. x = 33/5
