A recently negotiated union contract allows workers in a shipping department 24 minutes for rest, 10 minutes for personal time,

and 14 minutes for delays for each four hours worked. A time study analyst observed a job that is performed continuously and found an average time of 6.0 minutes per cycle for a worker she rated at 95 percent. What standard time is applicable for that operation? (Do not round intermediate calculations. Round your final answer to 3 decimal places.)

Answer:7.125 min

Step-by-step explanation:

Given

Resting time =24 min

Personal time=10 min

Delay=14 min

Observed Time=6min/cycle

Performance Rating=95%

Allowance Time=Rest time+Personal time+delay

Allowance time=24+10+14=48 min

Allowance %=\frac{Allowance Time}{Total Time}=\frac{48}{4\times 60}=20 \%

Allowance Factor=\frac{1}{1-0.20}=\frac{5}{4}

Calculate the Normal Time

Normal time=Observed time\timespersonal Time=6\times 0.95=5.7 min

Standard time=Normal time \times Allowance Factor

Standard time =NT\times Allowance factor=5.7\times 1.25=7.125 min

In the triangle, x is 5 greater than y, and y is 21 less than three times z, and the perimeter is 180. What is the value of each
svetlana [45]

Answer:

x = 77

y = 72

z = 31

Step-by-step explanation:

The formula for the Perimeter of triangle XYZ = x + y + z

From the question:

x + y + z = 180

In the triangle, x is 5 greater than y,

x = y + 5

y is 21 less than three times z

y = 3z - 21

3z = y + 21

z = y + 21/3

Hence:using substitution

x + y + z = 180

y + 5 + y + y/3 + 21/3 = 180

2y + y/3 + 5 + 21/3 = 180

2y + y/3 = 180 - ( 5 + 21/3)

2y + y/3 = 180 - (5 + 7)

2y + y/3 = 180 - 12

2y + y/3 = 168

Multiply both sides by 3

2y × 3 + y/3 × 3 = 168 × 3

6y + y = 504

7y = 504

y = 504/7

y = 72

Solving for x

x = y + 5

x = 72 + 5

x = 77

Solving for z

z = (y + 21)/3

z = (72 + 21)/3

z = 93/3

z = 31

Therefore,

x = 77

y = 72

z = 31
