According to Brookhaven National Laboratory, one unit of blood is roughly equivalent to one pint. With just one pint of blood, up to three lives can be saved.
Continue ReadingBrookhaven National Laboratory explains that within one unit of blood there are several components, including red blood cells, white blood cells, plasma, platelets and cryoprecipitate. Each component of blood can be stored for differing amounts of time, with plasma lasting the longest. While red blood cells carry oxygen to the body's organs and tissue, white blood cells are the body's primary defense against infection. Platelets help blood to clot. Each ill person requires differing amounts of the components that make up blood depending on his condition.

Full Answer >The break-even point in units is fixed costs divided by the difference between the sale price per unit and the variable cost per unit. Figuring out the break-even point is critical for business owners to come up with short-term and long-term financial plans. It is only possible to achieve a break-even point if the variable cost per unit is less than the price per unit.

Full Answer >One way to teach students proportions is to show them how to find a unit ratio and then to use multiplication to derive the desired result. Another method is to use cross-multiplication to find the unknown quantity in a pair of ratios. To illustrate the idea of proportions, it's best to tie the concept to a real-world situation rather than presenting it as an abstract pair of fractions. An example is to find the cost of two sets of items.
