Step-by-step explanation:
Answer:if they work together, it will take them 0.5 hours or 30 minutes
Step-by-step explanation:
jake can complete a job in 1 hour 30 minutes or 1.5 hours. This means that his unit rate is 1/1.5
his friend Harry can complete the same job in half the time. This means that Harry can complete the same job in 0.75 hours. His unit rate of working would be 1/0.75.
Since both of them work simultaneously at their individual rates, then, Their unit rates are additive. Assuming by working together, it took them t hours to finish the work. This means that their combined unit rate would be 1/t. Therefore,
1/1.5 + 1/0.75 = 1/t
1/t = 2
2t = 1
t = 1/2 = 0.5 hours or 30 minutes
Answer:
That would be 5 factorial = 5! = 5*4*3*2*1 = 120
Step-by-step explanation:
you have to show the graph
Answer:
As this is incomplete, it lacks the value of actual error.
Here, we do not know the actual value. so let's assume it is 1 inch
Relative Error = 6.25 % ≈ 6.3% = D
Step-by-step explanation:
As this is incomplete, it lacks the value of actual error.
We are asked to calculate the relative of the measurement.
Relative error formula = Actual error/Measurement x 100
Here, we do not know the actual value. so let's assume it is 1 inch
Actual value = 1 inch
Measurement = 16 inch
Relative Error = 1/16 x 100
Relative Error = 6.25 % ≈ 6.3% = D
D. 6.3%
