How do you draw a hexagon?

A geometric construction is a way of drawing a geometric shape using only a straight edge, a compass and a pencil. To draw a regular hexagon using a geometric construction, start by drawing a circle. After having drawn the circle, he takes the compass and places both ends on the edge of the circle. He then uses the straight edge to connect the two points. He places one end of the compass on the end of one line and the other end on the edge of the circle, forming another straight line. He continues the process until he has six lines around the edge of the circle.

Which numbers are less than 100 and have exactly three factors?

The factors of four are one, two and four. The factors of nine are one, three and nine. The factors of 25 are one, five and 25. The factors of 49 are one, seven and 49. The middle number of each factor list is used twice because that factor is squared, but since the factor is the same number, it is not counted twice.\nSquares of prime numbers are the only numbers that have exactly three factors. The other numbers under 100 with odd numbers of factors are one, 16, 36 and 81. The numbers 16 and 81 have five factors, while 36 has nine factors. All three of these numbers are exponentially larger t..

Who created exponents?

Up until the release of "The Sand Reckoner" around the year 216 BC, scientists and mathematicians discussed numbers as high as 100 million, which they referred to as a "myriad times a myriad" or 10,000 times 10,000. In order to discuss previously incalculable and inconceivable numbers, such as the grains of sand in the universe, Archimedes devised the system of exponents still in use today.

How do you write linear equations from word problems?

Making sentences out of the problem before determining variables can help. For example, if a problem reads, "45 less than 3 times a number is equal to that number. Find the number," sentences should be written that say:45 is less than 3 times a number.Let x be that number.From there, a person can begin to solve in equation form. While this is a simple word problem, the steps are always the same. The problem should now be written in equation form:45 less than 3 times a number equates to 3x - 45. "Less than" denotes subtraction, and "times" denotes multiplication. Note that the multiplication is..

How do you figure the mileage between cities?

If driving miles between the two cities are needed instead of flying miles, use the same method with the ruler and scale, but plot the distance along the roads. Add up the total distance traveled and use the scale to convert to miles. For example if the distance between to cities is 1.5 inches and the scale is 1 inch equals 100 miles, the distance between the two cities is 150 miles.

What are some tips for using a Canon calculator?

Canon calculators need a source of power to work correctly. Some models contain a tiny solar panel and don't have batteries, so they only work when there is enough light shining on the calculator. If this type of Canon calculator doesn't switch on, make sure nothing is covering the solar cell. Other models have batteries but no solar cell, so try replacing the battery if this type of Canon calculator doesn't work.\nCanon printing calculators can produce paper printouts of their results. Make sure the printing unit of this kind of calculator is supplied with paper and ink before ..

What is the meaning of numerical order?

An ascending numerical order is a sequence that starts with the lowest value and increases towards the highest, while the reverse is a descending order. Arranging numbers this way aids the search and analysis of items in a list for easier decision making. In a Microsoft Excel spreadsheet, items in a column can be ordered numerically by selecting the column and clicking the sort command.

How many cubic feet are in a 53-foot trailer?

For practical purposes, about 3,400 cubic feet of material fits into a 53-foot trailer. It is able to comfortably haul 34,000 pounds of cargo. A slightly smaller standard trailer size is 48 feet long. This transport about 3,000 cubic feet of goods. Maximum weight is 30,000 pounds. The average density of freight is assumed to be about 10 pounds per cubic foot.

What is the "greater than" symbol?

Generally, these symbols are used to show inequality between two values. They are first seen recorded in writing in the book "Artis Analyticae Praxis ad Aequationes Algebraicas Resolvendas" (The Analytical Arts Applied to Solving Algebraic Equations) by Thomas Harriot. He lived from 1560 to 1621, but his book was not published until 1631.

What are things that come in groups of twelve?

A dozen has long been a convenient measuring number. Unlike the number 10, 12 is evenly divisible by most single-digit numbers: 1, 2, 3, 4 and 6. Thus, it is easy to sell items by the dozen or by a fraction of a dozen. The custom of counting in dozens or multiples of dozens probably originated in Mesopotamia. Their sexagesimal system, using 60 as a base number, used the mathematical advantages of 12 and added the 5 and 10 as divisors.\nA dozen dozens, or 144, is termed a "gross." It is also of French origin, specifically "gross douzaine" or "large dozen." A "great gross" is a dozen gross. A "s..
