We all use basic arithmetic (+ - / *) in everyday life, and reading powers and scientific notation is useful for things like programming and reading some national geographic magazines and what not. The Pythagorean theorem is useful for some things. But I don’t understand how quadratic equations, calculus, radical expressions, sequences/series, and imaginary and complex numbers are used in everyday life. What are some REAL, USEFUL applications of these things?
You can measure milk using gallons, quarts and liters. Or pints
Of course, how else would you measure how much milk you'd have? You could measure in Imperial gallons, but the metric Litre (or Liter) is also a common way to measure liquid substance (which what milk is, a liquid).
A litre (or liter) is a measure of volume, not a measure of weight. A single liter of milk weighs ABOUT 1.03 kilograms.
gallons
You would measure the water in a bath tub in gallons.
The volume of a glass of milk would best be measured in millilitres.
gallons
Gallons are an Imperial measure of volume. Gallons are used in the USA and are about the same as 4 litres. Milk and gasoline are two examples of things measured in gallons.
a pound is a measure of force, normally the force of gravity on. a mass a liter is a measure of volumeI hope this helps
3.7854118 liters x 42 gallons is equal to 564.85094 liters.
use 2 litre jug and fill half
A gallon is larger than a liter, but if you measure some liquid, the number of liters will be larger than the number of gallons.
