For example, if a senate with 100 members attempts to pass legislation, and the senate's rules say that 20 percent of the voting members must be present to constitute a quorum, 20 senators must be present at the meeting in order for the group to move forward with a vote. If there were only 19 senators present, the group would have to suspend its actions.

Theorems are the embodiment of a general mathematical principle presented in simplest form. They can be combined and built upon to create complex mathematical models that describe the behavior of a system. Theorems can also be built on other generally accepted mathematical truths called axioms, which serve as the premise, or starting point, for a certain line of reasoning. Axioms are premises that are so evident, they can be accepted as true without controversy.\nTheorems are proven through the application of logical arguments that reach a well-defined conclusion through deductive reasoning.

When a string is plucked, the ensuing vibrations create sound waves. A faster rate of vibration produces a higher pitch, while slower vibrations produce a lower pitch. If the string is made half as long, the rate of vibration doubles, producing a pitch that sounds nearly identical to the original pitch, only higher. The interval between these two pitches is called an octave. Middle C, for example, vibrates at approximately 262 hertz. The C one octave above middle C vibrates at about 523 hertz, a 2:1 ratio reflective of the proportional division of the string. Other ratios produce other interva..
How many obtuse angles does a pentagon have?

The pentagon is a flat-shaped, five-sided polygon. Irregular polygons are considered convex or concave. When an internal angle of a pentagon is greater than 180 degrees, the pentagon is concave. A convex pentagon is not going to have any internal angles that are greater than 180 degrees, and no angles point inwards as they do within a concave pentagon. If any sides are curved, the figure is not considered a polygon.

Algebra.com's simplifier and solver allows students to input math problems and see how to perform the steps to reach the solution. All steps are included so that the student can learn the correct technique while solving the problem, and the site gives explanations for each step. The site even creates a link once the problem is solved, which allows the solution to be posted on another website if required.
How are decimals written in expanded form?

For example, the number 57.5 written in expanded form would be equal to (5 * 10) + (7 * 1) + (5 * 0.1). Each number is multiplied by its location value. The 7 is in the one's column, so it is represented by 7 * 1 in a bracket. If all of the individual brackets in the expanded form are evaluated and the results are added, the original number in decimal notation will be obtained.
How do you make a tetrahedron with paper?

Plan and design your tetrahedronThe two most basic designs for a paper tetrahedron involve either a large equilateral triangle or a parallelogram. You will have to draw one of these shapes. For both, you will need to include foldable flaps on which you can add glue.\n\nAn equilateral triangle has three equal sides that intersect at 60 degree angles, and one can be subdivided into four smaller equilateral triangles.\n\nIf you choose the parallelogram method, you will need to draw a quadrilateral with one set of sides twice as long as the other. One set of opposite angles are 60 degrees each, bu..
How many zeros does the number 1 million have?

These two systems are used to name large numbers. While one million is the same in either scale, the short scale and the long scale diverge with numbers greater than a million. For example, 1 billion has nine zeros in the short scale and 12 zeros in the long scale. Therefore, a billion in the long scale represents a larger number than a billion in the short scale. The short scale is found in American, Canadian and modern British usage. The long scale is found in continental European and older British usage.
What is a fact family?

Generally, a fact family consists of three numbers, two of which add up to the third. The numbers are related, and they always produce at least four math facts. When working with two numbers, two possible fact families can be made. A fact family is typically used in first grade math. It helps children study basic addition and subtraction facts in an easy way. It is used to learn and reinforce the connection between the two math processes.\nFor example, a fact family can be formed using the numbers 4, 6 and 10. In this family of three numbers, 6 and 4 are added to get the last number, which is ..
Which number best completes the sequence: 2, 9, 5, 13, 10, 19 and 17?

The differences between the numbers are 7, -4, 8, -3 and 9. The numbers switch on and off from adding or subtracting. Every time a number is added, it is one higher than the last number that was added. In the pattern so far, the positive numbers are 7, 8, and 9. Every time a number is subtracted, it is one less than the last subtraction. The negative numbers so far are -4, and -3. Using this pattern, the next number is 2 less than the last number in the sequence, 19. So, the answer is 17.
