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: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: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: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: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: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: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: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: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: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: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: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:The Fletching Calculator contains a list of the costs associated with the creation of bows and ammunition in the game RuneScape based on data from the Grand Exchange Market Watch. It helps players find out whether they are eligible to make an item or not.
A:Math is a field of study that attempts to describe and measure the physical world using models and numbers. Mathematics uses observation, simulation and experimentation as a means of discovering the truth behind natural phenomena, human behavior and social systems.
A:Manuals for Canon calculators are available on the Canon website, USA.Canon.com. The website features manuals for all types of Canon calculators and organizes them into categories labeled handheld, portable, printing, computer-link, and green; Canon's green calculators are environmentally-friendly calculators made from recycled materials.
A:An ERR:INVALID DIM error on a TI-84 calculator indicates that one or more STAT PLOTS is turned "on" but there are no values in the STAT lists. If the error occurs when trying to graph a function, then the error can be fixed by turning off the STAT PLOTS.
A:Calculator Soup and Rapid Tables offer free online calculators for converting percentages to decimals. Calculator Soup converts the entered percentage to a decimal, revealing the answer and the calculation of dividing the percentage by 100. The site also offers a reset button to quickly start another computation.
A:A significant figure counter counts the significant digits in any number, including that of scientific notation. Most sites that have a significant figure counter use a program in which the user enters the number into a box, clicks a count button and receives the answer. Counters differ from calculators.
A:To determine a percentage, divide the actual number by the total possible number, and multiply the result by 100. For example, if four out of five doctors agree on something, enter the equation in a calculator as "4 ÷ 5 x 100." The result, 80, is the percentage.
A:A ruler is often used to measure length. Length is a two-dimensional measurement as to how long an object is, how tall an object is or how far apart objects are. The most common units used to measure length include feet, yards, miles, centimeters, meters or kilometers.
A:Useful distance mileage calculators are featured on the websites of Rand McNally, World Atlas, and Globe Feed. These websites and many others can measure distance between cities, states and individual addresses.
A:A case-mix index is calculated by first choosing a period of time, such as a year. The hospital procedures should then be placed in diagnosis-related groups that the hospital billed, and the relative numeric weights should be gathered. Divide the sum of relative weights with the total diagnostic-related groups.
