A library contains 60000 books. 14,000 are on the subject of business and 22000 are on health care and 12000 on psychology and Law. What percentage of the librarys is on the if the computing books are two-thirds of the reminder

The percentage of computing books is 13.33%.

Step-by-step explanation:

The library consist of books on different subjects:

S = {Business, Healthcare, Computing, Psychology, Law,...}

There are a total of N = 60,000 books in the library.

Business (B) = 14,000

Healthcare (H) = 22,000

Psychology and Law (P&L) = 12,000

Remaining = N - B - H - P&L

                  = 60000 - 14000 - 22000 - 12000

                  = 12000

It is provided that computing books make up two thirds of the remainder

Compute the number of computing books as follows:

C = 12000 × (2/3) = 8000

Compute the percentage of computing books as follows:

%=%

Thus, the percentage of computing books is 13.33%.

you have to put the graph on here with the question

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
