The things you can apply to complete this job is workers and time. The job being accomplished is painted walls. This problem defines two jobs. The rate for each of the jobs will be the same. The first job rate is: R=(7 wkr)•(42 min)/(6 walls)R= 49 wkr-min/walls or 49 worker-minutes per wall. This means one worker can paint one wall in 49 minutes. If you think about this job if 7 workers take 42 minutes to do 6 walls it will only take them 7 minutes to do one wall. And it will take one person 7 times as long to do a job as 7 people working together. This first job rate equals the second job rate R=(8 wkr)•(t )/(8 walls)R=1 t wkr/wall where t is the time to do the second job. Setting the two rates equal to each other and solving for t. t=49 minutes It makes sense if one worker can paint one wall in 49 minutes then 8 workers can paint 8 walls in the same time.
Hi there! The answer is A. Add together 200 and 100. Then divide the sum by 6.
In this problem we want to know how many books there are on 1 shelf. Therefore we must first now the total amount of books and so we add up 200 and 100 (which makes a total of 300 books)
Finally we divide this total amount of books by the amount of shelfs (300 / 6), and then we've found the answer to our question. Hence, the answer is A.
Answer:
0.1538
Step-by-step explanation:
Probability of being dealt with an ace of a 8 =
= Number of ace + number of an 8 in the deck / Total number of cards in the deck
= (4+4) / 52 = 8/52 = 0.1538
Therefore 0.1538 is the required probability here.
Answer:
1,675.516
Step-by-step explanation:
The formula for a cone is V = pi r^2 h/3.
Plugging in the values of the radius and height, V = pi 10^2 16/3
Solving, you get:
V = pi 100 5.3333333
V = 1,675.516
