What is 1.25 as a fraction?

Another way to find the answer is to use an online decimal to fraction converter at onlineconversion.com.\nA mixed fraction is a whole number combined with a proper fraction. A proper fraction has a lower numerator than denominator. In an improper fraction, the numerator is higher than the denominator.

Is a trapezoid a parallelogram?

In an isosceles trapezoid, the two sides that aren't parallel are the same length and have the same angles relative to the parallel sides. Using an inclusive definition of a trapezoid that allows both pairs of sides to be parallel, rectangles fall under the definition of a trapezoid and are isosceles. The exclusive version of the definition omits these shapes since both pairs of sides are parallel.

Why is the variable "m" used for slope?

The slope of a line describes what angle it lies at. The slope can be calculated by dividing the quantity of change in the "y" direction, otherwise known as the rise, by the quantity of change in the "x" direction, otherwise known as run, over any segment of the line. Therefore, a high slope indicates that the line extends upwards quickly, while a low slope indicates a flatter appearance.

How do you subtract hexadecimal numbers?

Understand how to count with hexadecimal numbersJust as the decimal system has 10 digits, 0 through 9, the hexadecimal system has 16 digits. The 16 digits of hexadecimal are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F. Convert hexadecimal letters into decimal equivalentsWhen doing operations such as subtraction with hexadecimal numbers, think of the letters as equal to numbers, so A equals 10, B equals 11, C equals 12, D equals 13, E equals 14 and F equals 15.Line up numbers with more than one place, and subtract from right to leftFor a problem with more than one digit, line the two numb..

How do you use the Wolfram Alpha system of equations?

Determine the number of equationsThe easiest way to determine the number of equations is to count the number of variables. If there are two variables, then enter in two equations. The number of equations is not always explicit, and other methods to determine the correct number may be required.Fill in the equation boxesThe widget has four boxes where you can enter equations. Enter both sides of the equation, as entering only the left side causes an error. It isn't necessary to rearrange the equations into forms, such as y = mx + b. The widget rearranges them as needed.Submit the equations..

How do you find the mean?

Calculate the totalAdd together each number in the group to obtain the total, or sum, of the numbers. If numbers are duplicated, include each occurrence in the sum.Count the numbersCount how many numbers are in the group. If the same number occurs more than once, it should be counted more than once. Calculate the meanCalculate the mean by dividing the sum of the numbers in the group by the count of the numbers in the group.

Where is a y axis on a bar graph?

The y-axis is generally used for numerical measurements when comparing two or more items. The measurements on the axis usually begin at one, rising in evenly spaced sections along the axis to show the different sizes of the statistic that is being displayed in the graph. The name of each displayed item is shown on the connecting x-axis, which is placed at a 90-degree angle to the y-axis.

How do you convert 65 degrees Fahrenheit to Celsius?

Determine the correct equation to useIn the case of converting Fahrenheit to Celsius, the equation to use is (F - 32) / 1.8 = C.Enter the Fahrenheit temperature value Put the Fahrenheit figure into the equation. For this example, F = 65. \nSolve the equation To finish the conversion, do the math: 65 - 32 = 33, and 33 / 1.8 = 18.33. Thus, 65 degrees Fahrenheit equals 18.33 degrees Celsius.

What is the constant rate of change?

When graphing the constant rate of change, it is important that the variance of the x and y coordinates move in conjunction with each other. For each alteration in the horizontal x axis, there must be a complementary change in the vertical y axis. So long as the change is consistent between the two, the rate of change is constant. If the change in the x and y relationship changes, even if it occurs as a statistical outlier, the graphing equation will no longer be constant.\n\nIf a rate of change is constant, the line goes either up or down in a straight line that follows a sloped path when it ..
