The navy contract was for 2,314 devices and took 23 workers two weeks (40 hours per week) to complete. The army contract was for 4,707 devices that were produced by 16 workers in three weeks. What's the productivity of the army contract for the input of labor hours

0.408 hour / device

Step-by-step explanation:

As we know The army contract was for 4,707 devices that were produced by 16 workers which means 1 worker can produce: ≈294 devices in 3 weeks.

<=> 294 devices= 3*40 hours

<=> 294 devices = 120 hours

<=> 1 device = 120/294 = 20/49 ≈ 0.408 hour

So it takes 0.408 hour for a worker to finish producing 1 devicein the army contract

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

answer: 1+1

step-by-step explanation: 1+1 is at least 2
