The word "term" is used in mathematical equations to describe either a single number, or numbers and variables multiplied together. Numerical terms are then grouped into expressions to come up with a definitive answer to the equation.
A:Qualitative analysis is the scientific study of data that can be observed, but not measured. It is concerned with cataloguing the qualities of what is studied. Quantitative analysis is the study of data that can be measured, the quantities of a category of data. Each type of inquiry contributes important insights to scientific study that the other cannot.
A:Changing square feet to square meters requires use of basic conversion where one square meter equals 10.76 square feet. Hence, one square foot equals approximately 0.093 square meters. A house that has 2,500 square feet is 232.5 square meters in size.
A:To calculate the mass of a specific number of atoms of an element, divide the number of atoms by 6.02 x 1023 and then multiply by the molar mass of the element. The process for calculating mass from the number of atoms is the same for all elements.
A:The abacus is a basic mathematical computing device. It is still widely used today in Africa, Japan, Russia, China and other countries as a visual aid to facilitate the learning of mathematical concepts.
A:The formula to convert kilograms to pounds is pound = kilogram/0.45359237. Conversely, the formula is kilogram = pound x 0.45359237. One kilogram is equal to roughly 2.2 pounds, and 1 pound is roughly 454 grams.
A:There are many kinds of calculators, but most calculators have the same standard keys that allow users to complete a variety of calculations. The number keys and addition, subtraction, multiplication, division and equal signs are all very straightforward, but the functions of the other keys are not so well-known.
A:When purifying a substance in chemistry, use (collected mass/starting mass)*100 to calculate percent recovery. This formula is also commonly stated as (pure product recovered/crude material used)*100.
A:The word "term" is used in mathematical equations to describe either a single number, or numbers and variables multiplied together. Numerical terms are then grouped into expressions to come up with a definitive answer to the equation.
A:The common formula to find the area of an isosceles triangle is area equals 1/2 * base * height of triangle. The height is the line bisecting the two equal sides of the triangle and intersects the midpoint of the base.
A:Two early counting devices were the abacus and the Antikythera mechanism. The abacus and similar counting devices were in use across many nations and cultures. The Antikythera mechanism hails from the Greek island of Antikythera.
A:A real world example of an absolute value function is any calculation in which the total depends upon simple addition of all the quantities in the function, regardless of sign. One example of such a calculation is the number of feet traveled by an athlete running around a race track.
A:Popular online geometry calculators are located on websites such as CalculatorSoup.com, AnalyzeMath.com and Basic-Mathematics.com. These sites help solve geometric equations by computing an answer from values input by a student.
A:In general terms, the length of a stringer for a stairs is 14 inches for every step. For a more precise calculation, you need the know the height of the riser and the width of the tread for the steps.
A:The Math.com conversion table states that one inch is the equivalent of .0254 meters which is 25.4 millimeters. It is possible to convert any length in inches into millimeters by multiplying the number of inches by 25.4.
A:The Fahrenheit equivalent of 30 degrees Celsius is 86 degrees. The standard formula for converting Celsius to Fahrenheit is: Fahrenheit = 9/5 Celsius + 32. This is approximately equivalent to multiplying 1.8 times the degrees Celsius and adding 32.
A:Online calculators are used in the same manner as hand-held calculators. Calculations can be formulated online or the calculator can be downloaded to your computer. The numbers that require calculation can be inputted from the computer keyboard. Enlarged versions are available for individuals with weak eyesight.
A:Converting a metric unit, such as kilograms, to a U.S. Standard unit, such as pounds, is a matter of finding the correct conversion rate and multiplying. The conversion rate tells you how many of one unit equals another unit.
A:To calculate percentage, use the equation number/number = decimal *100 = percentage. On a calculator, type a number, followed by "/", another number, and then "=". A decimal appears on the screen. Multiply the decimal using the "x" and then type "100". The number on the screen is the percentage.
