Two of the dozen eggs are cracked. About what percent of the carton isn´t cracked? I also have like 4 or 5 others like this i need answers to. :)

83.3% are not cracked

Step-by-step explanation:

If 2 of the dozen are cracked, then 10 out 12'are not.

Percent = (part/whole)(100)

(10/12)(100) = (5/6)(100) = 83.3%

Hope this helps!

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:

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
