A recipe for a apple cider calls for 4 cups of apple and 3 cups of water. Witch equation can be used to find x, the percent of a apple juice in the recipe?

A.4/3=x/100
B.3/4=x/100
C.7/3=100/x
D.7/4=100/x

Idk can ya help me I think is b but am not sure what do you think?

i believe that the answers for this problem is B

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)
