How many workers will be needed to complete a task in 3 days given that 5 workers can complete the same task in 9 days?
12/3 = x/5 ⇔ 4 = x/5 ⇒ x = 20 workers. More workers reduce the duration for completing the same task.
How many workers will be needed to complete a task in 3 days given that it takes 4 days for 6 workers to complete the same task?
The job requires the input of 6*3 = 18 worker-days,so if you want to complete the work in 5 days you need 18/5 = 3.6 workers. So engage 4 workers for 4 days and call only 2 of them for the fourth and last day. 6 workers x 3 days gives us 18 workdays/man-days.
How do you solve math work?
To solve a work word problem, multiply the hourly rate of the two people working together by the time spent working to get the total amount of time spent on the job. Knowledge of solving systems of equations is necessary to solve these types of problems. Example: Latisha and Ricky work for a computer software company.
What is the rate of work?
The rate of doing work is equal to the rate of using energy since the force transfers one unit of energy when it does one unit of work. A horsepower is equal to 550 ft lb/s, and a kilowatt is 1000 watts.
Which of the following is an inverse proportion?
(v) The population of a country and the area of land per person. Solution: If two quantities are related in such a way that an increase in one quantity leads to a corresponding proportional decrease in the other, then such a variation is called inverse proportion.
How do you solve rate of work problems?
To solve a work word problem, multiply the hourly rate of the two people working together times the time spent working to get the total amount of time spent on the job. Knowledge of solving systems of equations is necessary to solve these types of problems.
How do you calculate rate of work?
The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.
What is the additive inverse of 3 by 7?
-3/7
Additive inverse of 3/7 is -3/7
How do you do inverse proportions?
The formula of inverse proportion is y = k/x, where x and y are two quantities in inverse proportion and k is the constant of proportionality.
What is the work rate formula?
Your new formula is R * T * N = W (Rate for each * time * number of workers = total work done).
How many days does it take to make 6 of workers?
Ivy Global is a leader in preparing students for the SAT, ACT and PSAT. As it not possible to have 0. 6 of a worker, an alternative is 18 worker days divided by 4 men = 4.25 days based on prorata rates. If it takes one woman 9 months to make 1 baby, how many women does it take to make 1 baby in 1 month?
How many days will it take 9 men to complete the job?
We say that p is inversely proportional to d. 144 men-days = 144 men-days = k, the nonzero constant of variation for this problem. Therefore, it will take 16 days for 9 men to complete the job. , Mathematics teacher at a government college in India.
How many workers does it take to do the same work?
In other words it would take 1 worker 18 days to accomplish the same work (assuming collaboration was not necessary for expediency or safety) If you divide that resulting 18 by the new value for days which is 5, you get the following result: So 3 workers will not be enough and 4 will be more than enough.
How many days does it take to finish the work?
The total work can be finished by in 7 days if 5 men work each day. Therefore, one man can finish the work by 7×5 = 35 days. If this work is shared by 7 workers the work can be finished in 35/7 = 5 days.
