What is 482 students to 20 teachers?

10 teachers to 241 students

Step-by-step explanation:

Number of students  = 482

Number of teachers  = 20

Unknown:

ratio of students to teachers = ?

Solution:

To find the ratio:

     Number of students :  Number of teachers

                  482               :           20

Reduce to the smallest value, divide by 2;

                  241                 :           10

In the class there are 10 teachers to 241 students

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
