How do you find the product of fractions?

Simplify the fractionsReduce the fractions to the lowest common terms to where the same number can divide both the numerator and denominator of the fraction.Multiply the numerators and denominatorsMultiply the top number of one of the fractions by the top number of the other fraction. Multiply the bottom number of one of the fractions by the bottom number of the other fraction.\nSimplify the fraction againRe-write the fraction with the product of the numerators over the product of the denominators, and simplify the fraction to its lowest terms.\n

How do you graph a reflection across the x axis?

Determine the coordinates of the original imageDetermine the original image's coordinates, and write them down in (x, y) format. The x axis is always the horizontal line on a graph, while the y axis is always the vertical line on a graph. Draw a line from coordinate to coordinate to ensure that the reflected image matches the original image.Flip the y coordinates of the original imageDetermine how the y coordinates should be flipped. Positive y coordinates must become negative – that is, (x,y) changes to (x,-y) – while negative y coordinates must become positive – (x,-y) changes to ..

Why is a circle 360 degrees?

The sexegesimal counting system devised by the ancient Babylonians has left numerous marks on modern systems of geometry and mathematics. The number 60 is extremely convenient for rapid calculations, as it is a highly composite number that is divisible by all integers from 1 to 6, as well as 10, 12, 15, 20, 30 and 60. The Babylonians used a 360-day solar calendar, a 60-second minute and a 60-minute hour, according to The Story of Mathematics.\nThe Babylonians assigned 360 degrees to circles as an aid to time tracking. Using a 360-day calendar made it easy to associate each day of the year with..

How many pallets fit on a truck?

As there is no global size standard for pallets, the actual number of pallets that can be carried by a standard-sized truck varies depending on both pallet size and cargo weight. A truck that can fit 34 export-standard pallets, for example, may not be able to fit all of them; the cargo weight could go up to 75,000 pounds, as each pallet is capable of carrying loads of around 2,200 pounds.

What is the square root of 132?

The square root of a number, "y," is the number, "x," that when multiplied by itself results in "y," as in "x" times "x" equals "y." For the number 132, 11.48 times 11.48 equals 132. The square root of a number can be simplified by factoring out the square root of a whole number. For example, the square root of 132 can be written as the square root of four times the square root of 33.

What is a piecewise function grapher?

To draw the graph, each part of the piecewise function is entered, starting with the first piece and the first condition. For example, x2 + 11, x < 0 are entered first, then 11 - 4x, 0 ≤ x ≤ 2 and finally x2 – 3x + 5, x < 2. The graph draws the line for x2 + 11 only for values of x that are less than zero. Conditions for the other pieces are fulfilled as well.

What are some examples of a lurking variable?

A variable is any factor that can be controlled, changed or measured in an experiment. There are several types of variables used to report the data collected from an experiment. The most-common types of variables are the independent, dependent, controlled and extraneous variables.\nThe independent variable is the variable or condition that the experimenter changes and controls during the experiment. The dependent variable is what is measured or obtained during the experiment. It is dependent upon the independent variable and its varying states. A controlled variable is a constant variable that..

How many lines of symmetry does a rhombus have?

A line of symmetry is a plane that can be drawn through a two-dimensional figure to yield two perfectly mirrored sides. If the shape was folded over the line, all of the edges on either side would match up exactly. A rhombus has two lines of symmetry that run through one vertex to the one directly across it. Unlike a square, planes through the center of each edge of a rhombus do not yield mirrored sides.

How many curved faces does a cone have?

There are two main components of a cone that are important for describing the shape of a cone. The base is always a circle, but its size will depend on its radius. The second main part is the height of the apex, which is the distance from the base to the top point of the cone. A large base with a small apex height will have sides that are much less steep than a small base with a high apex.

What does the "C" stand for in Roman numerals?

The Romans used certain letters to represent numbers. In addition to "C,"the Roman numerals are:I: 1V: 5X: 10L: 50D: 500M: 1,000Additional numbers can be created by addition and subtraction. When several of the same number was written in a row, the group was added together. For example, XX is 10+10, which is 20. If a smaller number was before a larger one, then the number was subtracted. For example, IX is 10-1, which equals 9.
