Laura is a chemist working with liquids and solutions. she has two large cylindrical barrels that can hold up to 2,000 liters each. the first barrel contains 900 liters of solution, and the second barrel contains 100 liters of solution. laura begins draining the first barrel at a rate of 36 liters per minute at the same time she begins filling the second barrel. laura fills the second barrel with 44 liters of solution every minute. which inequality represents the seconds, s, when the second barrel contains a greater or equal amount of solution than the first barrel?

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
