Javier is also kayaking, he can go 1 mild in 2/3 of an hour. how far can he go at this rate in 3 hours?

The distance cover by Javier in 3 hours is 4.5 miles

Step-by-step explanation:

Given as :

The distance cover by Javier in hour = 1 mile

Let The distance cover by Javier in 3 hours = x miles

Applying unitary method, we get

∵ In   hour , distance cover by Javier = 1 mile

So, In 1 hour , distance cover by Javier = mile = mile

Or,  In 1 hour, distance cover by Javier = 1.5 miles

∴  In 3 hours , distance cover by Javier = 1.5 miles × 3

i.e x = 4.5 miles

So, The distance cover by Javier in 3 hours = x = 4.5 miles

Hence, The distance cover by Javier in 3 hours is 4.5 miles  Answer

f

step-by-step explanation:

f

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)
