An art academy requires their to be 3 teachers for every 75 students and 6 tutors for every 72 students. how many tutors does the academy need if it has 120 students?

Remark

All you need to do is set up a proportion for 6 tutors and 72 students. The number teachers is not relevant, nor is their relationship to the number of student assigned to 3 teachers.

All you are asked about is the number of tutors for 120 students.

Proportion

6/72 = x / 120 Cross multiply

72x = 6 * 120

72x = 720 Divide by 72

x = 720 / 72

x = 10

10 Tutors are needed for the entire school. <<<<<< Answer

ik how do do this just give me a few minutes and i will give it to

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
