This is a units conversion problem: you have time and you want to convert that to money. Any units conversion problem involves multiplication by 1 in various forms. When you are given 7.5 min = 1 bottle = 500g, you know that (500 g)/(7.5 min) = 1 because the numerator and denominator are equal. (Of course, you are aware that 500 g = 0.500 kg.) The idea is to choose the forms of 1 that cause units you don't want to cancel, leaving only the units you do want.

Every whole number<span> is a </span>rational number: for example, 3=31. ... Everywhole number<span> n can be written as a fraction of integers: n=n1. We aren't required to write it that way; we just need to know that it is possible to express every </span>whole number<span> as a fraction of integers, and hence it is </span>rational<span>.
So I Believe the Correct Answer would Be D)</span><span> If a number is not a rational number, then it is not a whole number. The converse is true</span>
F (x) = x^3 - 27 / x^2 + 2x - 15
Answer:
A. 
Step-by-step explanation:
![\dfrac{\sqrt[3]{6}}{\sqrt[4]{6}} = 6^{\frac{1}{3} - \frac{1}{4}} = 6^{\frac{4}{12} - \frac{3}{12}} = 6^{\frac{1}{12}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csqrt%5B3%5D%7B6%7D%7D%7B%5Csqrt%5B4%5D%7B6%7D%7D%20%3D%206%5E%7B%5Cfrac%7B1%7D%7B3%7D%20-%20%5Cfrac%7B1%7D%7B4%7D%7D%20%3D%206%5E%7B%5Cfrac%7B4%7D%7B12%7D%20-%20%5Cfrac%7B3%7D%7B12%7D%7D%20%3D%206%5E%7B%5Cfrac%7B1%7D%7B12%7D%7D)
