Use the table below to answer the question.
You are working as a quality control engineer. You test four machines to determine their efficiency. The LEAST efficient machine needs to be sent in to a special shop to be repaired. Which of the following machines is most likely in need of a trip to the repair shop?
Efficiency=(Output Work/Input Work) x 100%

Machine A
Machine B
Machine C
Machine D
To determine which machine is the least efficient and likely needs to be sent to the repair shop, we can use the efficiency formula provided in the table:
Efficiency = (Output Work / Input Work) x 100%
We need the actual values of both the output work and input work for each machine in order to calculate their efficiencies. Once those values are provided, we can compare the efficiencies of all four machines and identify the machine with the lowest efficiency, which is the one most likely in need of repair.
What is the answer?
Apologies for the confusion, but without the actual values of output work and input work for each machine, we cannot determine the least efficient machine and the one most likely in need of repair. Once those values are provided, we can calculate the efficiencies and identify the machine that needs to be sent to the repair shop.

Apologies for the confusion. Since no specific values are provided for the output work and input work of each machine, we can look at the options based on efficiency.
Here is how we can determine the most likely machine in need of repair based on efficiency:
- Machine A: If Machine A has the lowest efficiency, then it is most likely in need of repair.
- Machine B: If Machine B has the lowest efficiency, then it is most likely in need of repair.
- Machine C: If Machine C has the lowest efficiency, then it is most likely in need of repair.
- Machine D: If Machine D has the lowest efficiency, then it is most likely in need of repair.
Without the specific efficiency values, we can only make a determination based on hypothetical scenarios. Please provide the efficiency values for each machine to make a more accurate determination.
. A college campus is adding a new wheelchair ramp to assist certain students who have physical disabilities. A wheelchair ramp is an example of a simple machine called an inclined plane. Which of the following statements best explains how the wheelchair ramp changes the force of someone using a wheelchair?

The wheelchair ramp changes the direction of the force and and neither increases nor decreases the distance.
The wheelchair ramp does NOT change the distance or direction of the force.
The wheelchair ramp changes the direction of the force and decreases the distance of the force.
The wheelchair ramp changes the direction of the force and increases the distance of the force.
The statement that best explains how the wheelchair ramp changes the force of someone using a wheelchair is:
"The wheelchair ramp changes the direction of the force and decreases the distance of the force."
This is because an inclined plane like a wheelchair ramp allows the wheelchair user to exert their force in a different direction (upwards along the ramp) rather than straight up a vertical slope. This change in direction reduces the amount of force required to move the wheelchair up the ramp, making it easier for the user compared to lifting the wheelchair straight up without the ramp.
