If m workers can complete a job in d days, how many days will it take n workers, working at the same rate, to complete one third of the job? express your answer as a common fraction in terms of d, m and n

Step-by-step explanation:

We can use the formula shown below to solve this problem.

RWT = J

Where

R is the rate

W is the workers

T is the time

J is the number of jobs

First,

W = m

T = d

J = 1 [since it is said 1 job]

Lets find the Rate (R):

RWT = J

R(m)(d) = 1

R =

Now, using this value of R, we are going to find T, given:

W = n

J = 1/3

R = 1/md (found earlier)

So, let's find T:

RWT = J

This is the time it will take, in terms of d, m, and n

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

probably .5

i can on others if necessary.
