100cm
Step-by-step explanation:
the difference between of 5cm
Last one: Use employee identification numbers to randomly select 200 employees.
It's the most random.
First, find her rate for the day. Since she runs 10 laps a day, multiply.
400 times 10= 4000
Next, I'll convert kilometers into meters;
12 times 1000=12,000
Divide to find the days:
12,000/4,000=3
It will take 3 days to run a total of 12 kilometers.
Answer:
3 times greater
Step-by-step explanation:
6.7 x 10 to the 6 = 6700000
2x 10 to the 7 = 20000000
20000000/6700000 = 2.98507462687
Rounded - 3
The unit rate is obtained by dividing the amount of work done by the unit time. In the problem, we are already given the total number of parts manufactured (amount of work done) and the total amount of time to manufacture (7 hours).
Obtaining the unit rate is as simple as dividing 1116 parts by 7 hours, as shown below:
Unit rate = 1116 parts / 7 hours
Unit rate = 159.42857
Therefore the unit rate is approximately 159 parts/h.
