A rectangle has four straight sides with four right angles, but the sides can be different lengths. The opposite sides of a rectangle must be parallel with one another and feature equal lengths. This means the shape can be tall and skinny or short and fat. The sides on a square must all be parallel in comparison with one another.

There are several other fictitious numbers commonly use to express large quantities, including bazillion, gajillion and katrillion. These made-up numbers sound similar to real numbers, like million and billion, because they all end in "-illion". Though gazillion is not an actual numerical term, it is an actual word in the English language and can be found in the dictionary as an adjective.

Record your BTU value to startYou will start by writing (or inputting into a calculator) your BTU value. As an example, use 6,000 for BTU that you wish to convert to kWh.Divide your BTU value by the kWh conversion factorIn this example, you will divide 6,000 by 3412.1414799. Take note of your final answerWhen you divide 6,000 by 3412.1414799, you will arrive at 1.76 kWh. This means that you will use 1.76 kilowatts of energy per hour to generate 6,000 BTU of heat. As an example, if the 6,000 BTU heater is running at an electricity rate of $1 per kW, approximately every 11 hours you will spend a..

Changing mixed numbers to a simple fraction makes certain mathematical problems easier to complete. There are not many steps to the process and, once learned, it is quite easy to do.Step 1: Multiply the denominator by the whole numberMultiply the denominator, or the number on the bottom of the fraction, by the whole number in the mixed number. For example, using the fraction 2 3/5, one multiplies 5 times 2 to get 10.Step 2: Add the answer from Step 1 to the numeratorTake the answer from the multiplication step and add it to the numerator, or the number on top of the fraction. Using the 2 3/5 e..

The cosine of an angle is evaluated by forming a right triangle and finding the ratio of the length of the side adjacent to the angle over the length of the hypotenuse. The hypotenuse is the longest side of a right triangle and is opposite the 90 degree angle. An angle can be expressed either in degrees or in radians, which is based on the segment of a circle represented by the angle.

Engineers must have an understanding of angles and planes, as this is one of the most common applications in their job. Both mechanical and civil engineers make use of the mathematical understanding of planes to break down curvatures, patterns or electrical fields into mathematical terms. Mechanical systems can be imagined and drawn in mechanical terms, and problems in these systems can be solved with geometric understanding. Structural engineers are tasked with creating structurally sound buildings while making aesthetic additions from a designer possible. Structural engineers can also map li..

The cosine is a trigonometric function. Other functions used in trigonometry are tangent and cosine, and all of these functions are related to one another. The tangent is calculated as the sine divided by the cosine. The cosine is the reverse of the sine and is equal to the quotient of the length of the side of a right triangle opposite the acute angle divided by the length of the hypotenuse.

Distance calculators can be found on many online map tools and a variety of smartphone applications. To find the distance between any two points using one of these electronic tools, enter the address or intersection for each of the points and select the mode of transportation. Often, a tool that gives directions does not calculate the distance using a straight line, instead measuring the distance required to travel between two points on public roads.\nTo calculate distance using the Pythagorean theorem, find the longitude and latitude coordinates or intersections on a grid. This will indicate ..
How many faces does a pentagonal pyramid have?

In a regular pentagonal pyramid, the base is a regular pentagon, which means the sides and angles are all equal. This means that the five triangular faces are also identical to each other. The surface area can be calculated by determining the area of the pentagon as well as one of the triangles before multiplying it by five, and then adding them together. The volume can be calculated by multiplying the base area by the height and dividing by three.

Abstracts are a key component of published academic papers, and are very often required by publications, proposals to conferences or publishers, and academic societies. The abstract of a math paper is designed to give an overview of its contents and introduce the reader to the ideas contained within. Abstracts help readers decide if the paper they are attached to is pertinent to their own research or is potentially interesting to read.
