What is the square root of 36?

The symbol used to indicate "square root" resembles a checkmark and is known as a radical. When this symbol is used, the result is always positive. However, since two negative numbers multiplied together results in a positive number, the square root of 36 can also be -6. Other common square roots are:2 is the square root of 43 is the square root of 94 is the square root of 165 is the square root of 5

How do you add fractions and whole numbers?

Write the fractionFractions consist of two parts. The numerator is written on top, and the denominator is written at the bottom, under a horizontal line. Fractions can also be written in a straight line, using a forward slash; for example 1/2 equals one-half. Denominators tell how many parts a whole has been divided into. Numerators stand for how many of these parts there are. For instance, in the fraction 5/6, there are five parts of the total six parts.Add fractions with the the common denominatorTo add fractions, denominators must be the same. For instance, in fractions 1/5 and 3/5 the deno..

How many edges does a pyramid have?

In addition to the traditional Cheops or square pyramid, there exists what is known as a triangular pyramid. A triangular pyramid has only six edges. In addition, this type of pyramid has four faces and four vertices. Other types of pyramids not commonly seen include a pentagonal pyramid, a hexagonal pyramid and a heptagonal pyramid. These more unusual types of pyramids are most often seen in educational and classroom settings.

How are logarithms used in the world?

A logarithm used to describe the intensity of an earthquake can be expressed as R = log I. "R" is equal to the magnitude of the earthquake, which is measured by the Richter scale. "I" is equal to the intensity of the earthquake when measured against the reference value. The reference value is equal to lo = 1 and is the smallest level at which seismic activity can be detected. An increase of 1 on the Richter scale means the magnitude of the earthquake is 10 times greater.\nSound intensity can be expressed as β = 10 log ( I / I0 ). Sound is measured in decibels, and I0 is the smallest intensity..

What is the multiplication property of equality?

For example, in order to solve the equation 5x=7, try to get x on its own by dividing 5x by five. Because you divided 5x by 5, you must do the same the other side of the equal sign. Then the answer will be x=7/5.\nAnother example is 2x=8. In order to solve the problem you must divide both sides of the equation by 2. Hence the answer is x=4.

What is the best method for dividing polynomials by binomials?

These steps are repeated until the remaining polynomial terms have lower degrees than the binomial. Divisions that result in a remainder can be written in two ways, one of which involves writing the remainder by denoting it with the letter "R." A better way, however is to express the remainder as a fractional number. The remainder is typically the numerator, while the divisor is the numerator of the fraction, which is usually added to the quotient. It is advisable to check the result by multiplying the quotient by the divisor and adding the remainder term. Some polynomials have missing terms, ..

What is the meaning of quantitative techniques?

Researchers use quantitative techniques across a number of disciplines including communication studies, medical studies, statistics and a host of other social sciences like education. Researchers gather information with specific research instruments in order to get an objective measurement. With the information gathered from these observations, researchers make inferences about a larger population after looking at a representative sample size.\nQuantitative techniques must have high reliability so that other researchers have the ability to replicate the studies with the previous data collectio..

Why is standard deviation useful?

Standard deviation is a fundamental calculation for analyzing a set of data in relation to its mean. It is crucial for measuring volatility and error from multiple pools of data. It measures whether a set of data or a specific point is close to the group's mean or spread out over a vast range.\nStandard deviation is commonly used for research and analytics. It is used by financial institutions and investors to measure a security's historical and expected volatility. In science, it is commonly applied to test for random errors or variations in experimental data. As a basic statistical..

What is a stem and leaf plot with decimals?

All stem and leaf plots are set up with one string of numbers running from smallest to largest on a vertical axis, separated by a straight line from another series of numbers. Each series of numbers on the right of the line are separated by commas and correspond to one of the numbers on the left. In a regular stem and leaf plot, the number on the left represents the tens place, and the numbers on the right are the ones place of each number that occurred in the data set, according to Purplemath.\nWith a decimal-based stem and leaf plot, the setup is similar. Instead of the left and right sides ..

What is the diagonal of a quadrilateral?

There are a variety of diagonals that are found with different quadrilaterals. Mutually bisecting diagonals cut each other in half, as the two pieces of each diagonal are equal. Parallelograms, rhombuses, squares and rectangles contain mutually bisecting diagonals. Perpendicular diagonals produce right angles where they meet. Squares, rhombuses and kites all fit this category. Perpendicular bisecting diagonals occur when either of the two types of diagonals form four 90-degree angles where they meet and cut each other in half. A rhombus and square both fulfill this requirement. A trapezoid is ..
