Answer:
Step-by-step explanation:
The easier way to figure this is by using the concept of torque in physics. If the torque of the man is greater than that experienced by the box, the lever will tilt in the man's favor (in other words, he will move down and the box will be lifted). Torque is found by multiplying the perpendicular force by the length of the lever arm. Because we want the man's torque to be greater than the box's torque, the inequality is:
 and
 and
 That decimal is 6 inches in terms of meters.
 That decimal is 6 inches in terms of meters.
180r > 76.2 so
r > .42 meters or `16.67 inches. The man has to sit at a distance greater than 16.67 inches in order for the box to be lifted by the lever.

The are 8 blue bicycles, 6 green bicycles, and 4 yellow bicycles and total they equal 18.
        
             
        
        
        
Answer: 288 students
Step-by-step explanation:
<u>First Step: find the number of students per bus</u>
Given
- 144 students
- 4 bus
Solve
144 students/4 buses=36 students/bus
<u />
<u>Second Step: apply the rate to find the number of students in 8 buses</u>
Given
- 8 buses
- 36 students/bus
Solve
8×36=288 students
Hope this helps!! :)
