Could someone tell me if I got these problems right.
A man used 1 pt. 9fl oz. of cleaner, then he used 2 pt 10 fl oz. out of a 3 qt. bottle. How much cleaner is left?
= 1 pt. 13 floz
The United States emitted 19.5 million t of nitrogen oxides(NO) into the atmosphere in 1987. One metric ton (1 t) equals 1,000 kg. How many kilograms of NO were emitted to the atmosphere in the United States during 1987?
19,000,000,500 kg
A quart is 32 fluid ounces. (A fluid ounce is a unit of volume, not mass or weight). So subtract 25 fl oz. and 42 fl oz. from 96 and you get 29 fl oz. = 1 pint 13 fl oz. You are right on that one.
19.5 million tons x 1000 kg/ton = 19.5 billion kg
