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: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: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: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 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 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 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 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: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:To calculate percentages on a calculator, divide the part by the whole and then multiply the answer by 100. For example, to find what percent of 80 is 20, divide 20 by 80. The result is 0.25, then multiply 0.25 by 100 which equals 25 percent.
A:If someone has 2 quarters, 4 dimes, 2 nickels and 1 penny, they have a total of $1.01. Every coin has a designated value. When counting money, one simply has to add these values together. Money is measured in cents. One dollar is equivalent to 100 cents.
A:Arctangent is the inverse of tangent, and itÂ refers to finding the angle whose tangent is given byÂ a number or ratio. For example, the arctangent of 1 is equal to an angle that measures 45 degrees. This is the inverse of finding the tangent of 45 degrees, which equals 1.
A:Customers can view online manuals for Casio products by visiting the Casio website, clicking on the support menu and clicking on the manuals link. The manuals section of Casio's website includes manuals for several Casio products, such as calculators, digital cameras, mobile phones and clocks.
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 use a CFM (cubic feet per minute) calculator to determine airflow needs for a room, know variables such as the volume of the room and the number of times the air changes per hour from the fan/ventilation system and apply them to a formula. CFM is an engineering calculation used to find the heating needs of a room.
