How do I find the ratio between two numbers?

Determine if the two numbers have a common factorRatios are usually the simplest representation of two quantities. The numbers that form the ratio should therefore be reduced to their simplest terms by dividing the numbers by their greatest common factor, if they have one. For example, for the ratio of 20 red balloons to 15 blue balloons, the numbers would be divided by 5. The number 5 is their greatest common factor, and it reduces the quantities to their equivalents of 4 red balloons and 3 blue balloons.Arrange your numbers in the desired ratio formatChoose the format in which the ratio is t..
How many megabytes are in a terabyte?

Although operating systems read the amount of space in a hard drive using the binary method, computer storage manufacturers generally market their hard drives' unformatted capacity in decimal mathematics. Using this method to calculate capacity, an unformatted 1-terabyte hard drive can store 1,000,000 megabytes of data. The International Electrotechnical Commission has introduced the new binary prefixes "mebi," "gibi" and "tebi" to resolve the discrepancy, although they are seldom used.
How do you figure out if a relation is a function?

If the relation is represented in the form of a T-chart listing x- and y-coordinates, the two columns are examined closely to ensure no x-value is matched to more than one y-value. If there is a one-to-one correspondence from x-values to y-values, the relation is a function.\nTo decide whether a relation is a function, when expressed as an equation, one solves for y and notes whether the equation has more than one solution. If there is only one possible correct answer, the relation is a function.

The Italian term "per cento" means "of hundred." Trade in Italy involving large sums of money was common, and 100 had become a common base for financial transactions. An anonymous manuscript from 1425 by a scribe has a "pc" where a little loop adorns the "c." Over the next two centuries in Europe, the sign evolved into a combination of a loop and a fraction bar. By the 19th century, the tilted fraction bar became very common and replaced the usage of the horizontal bar.
How many lines of symmetry does a star have?

In math, a symmetry line refers to an imaginary line that one can fold an image or shape such that both halves match exactly. In a five-pointed star, there are five of these lines. One finds these symmetry lines by drawing a line that extends from the top of each of the five points to the opposite side. In each case, the two halves of the star formed are symmetrical.

Pi, by definition, is the ratio of a circle's circumference to its diameter. The result when the circumference of a circle is divided by its diameter, is a constant with a decimal extension that neither terminates nor becomes periodic. Its closest decimal equivalent is 22/7.\nPi is also a transcendental number, which simply means it is not an algebraic number, nor a root of any nonzero polynomial comprising of rational coefficients. All transcendental numbers are also irrational.

Find point-slope formPoint-slope form is given by relating x and y variables to their values at a specific coordinate and multiplying by the slope. The formula is (y-value(y))=m(x-value(x)), where m is the slope.\n\nAt the point (1,3), x=1 and y=3. If the slope is 2, the point-slope form of the equation is (y - 3) = 2(x - 1).Use distributionDistribute the slope coefficient to both the x and the x coordinate inside the parentheses.\n\nFor ( y- 3) = 2(x - 1), rewrite it to (y - 3)=x*(2)-1*(2). Simplify the function to (y - 3) = 2x - 2.Isolate yIsolate y by canceling out any constants or coeffici..
How do you write out in figures 1 million?

Another way of expressing 1 million is using the Roman numeral system, wherein 1 million is written as a capital letter M with a bar on top. The letter M has a value of 1,000, and placing a bar on top of it multiplies the value with another 1,000.\nOne million can be better visualized using paper money. A dollar bill weighs 1 gram, so 1 million one-dollar bills weigh 1 ton. Using the unit of time, 1 million seconds is equal to 11.57 days.

The cosine values around the unit circle range from 1 to -1. Cosine has a value 1 at zero degrees and a value of -1 at 180 degrees. The other values assigned to cosine by the unit circle are 0.87 at 30 degrees, 0.71 at 45 degrees and 0.50 at 60 degrees. These values alternate between positive and negative depending on the quadrant in which they lie.

A normal distribution or bell curve is arranged symmetrically on either side of the mean (sometimes the median is used). Some teachers grade their students' exams on a bell curve, according to K12 Academics. This is a method of assigning a grade score that is relative to other students' performance. The teacher decides which grade represents the mean, or median, and then assigns grades by following the normal distribution. More often applied at the university level rather than in the lower grades, bell-curve grading usually involves the choice of C as the median grade.\nAnother way o..
