Thirst Quencher

In the summer months, a common problem people suffer from is dehydration – not enough water in their body. Waiting until you feel thirsty is not a good indicator that it’s time to drink water. In fact, once thirst has settled in, you are already dehydrated! A general guideline is that people should drink eight 8-ounce glasses of water per day. According to this guideline, how many gallons of water should a person drink in a day, given that 1 gallon = 4 quarts and 1 quart = 32 ounces? Express your answer as a decimal to the nearest tenth.

Father's Day

The Day That Goes on Forever

March 14 has been dubbed Pi Day.  That’s because March 14 is often written 3/14, and a decimal approximation of pi is 3.14.  But that’s only if you use decimals and our style of writing dates.  In some countries, it’s customary to list the date first followed by the month; for example, March 14 would be 14-3 in some places.  Consequently, some places celebrate Pi Approximation Day on July 22, because that date can be written as 22-7, and a fractional approximation of pi is 22/7. What percentage of the year occurs between Pi Day and Pi Approximation Day?
