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: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: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: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: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 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: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: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: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 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 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:140 degrees in Fahrenheit is 60 degrees Celsius. There is a mathematical formula, °C = (°F - 32) × 5/9, which can be used to convert any temperature in Fahrenheit to Celsius.
A:"ERR:INVALID DIM" is an error message that comes up when one or more of the calculator's "STAT PLOTS" are set to "on" but there are no values or incomplete values in the "STAT" lists. It can also mean the user entered the wrong type of data.
A:To convert 450 degrees Fahrenheit to Celsius, take the Fahrenheit value and subtract 32, then divide the difference by 1.8 and the result will be its equivalent in Celsius. The formula for converting Fahrenheit to Celsius is simple and when the formula is followed properly, 450 degrees Fahrenheit should have an equivalent of 232.222 in the Celsius scale.
A:"24KGB" is short for 24-karat gold bonding. This is a technique in which base layers of 24-karat gold are covered with layers of 14- or 18-karat gold to create a more affordable replica.
A:A height of 5 feet 10 inches is the equivalent of 177.8 centimeters. One inch is equal to 2.54 centimeters. To convert inches to centimeters, it is necessary to multiply the number of inches by 2.54.
A:A number with more than two factors is called a composite number. A factor is a number that is evenly divisible into another number. Prime numbers, by definition must be larger than one and have only themselves and one as factors.
A:Meta-Calculator and Alcula offer advanced calculators online. Meta-Calculator provides users access to graphing, scientific, matrix and statistics calculators. Alcula, however, provides one scientific calculator that supports many operators, functions and constants, such as trigonometric and statistical functions.
A:The multiples of 24 are an infinite series of numbers that result from 24 being multiplied by any whole number. The first five multiples of 24 are 24, 48, 72, 96 and 120. These numbers come as a result of 24 being multiplied by 1, 2, 3, 4 and 5.
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:Wire size calculators use metric measurements, but not imperial measurements. However, a chart is available to convert metric measurements to imperial measurements once the measurement has been calculated.
