Ellen had 25 hair clips.7 of them and the rest were purple , what precent of the hair clips were blue, what percent of the hair clips were purple Pls helppp

7/25. then do 25-7. take that answer and divide by seven

Step-by-step explanation:

also, make sure to divide the smaller number by 25! it seems weird but it should work! fell free to use a calculator

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)

step-by-step explanation:

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
