What is the "greater than" sign?

One way to remember which side represents greater or less than is to remember that the smaller end of the symbol always points to the smaller number of the two represented. A fun way for children to remember which way means greater than is to call the symbol an alligator. The alligator eats too much, pointing to the larger value.

What is 20 pounds in kilograms?

The metric system uses natural objects and the decimal system to make measurements easier. For example, a liter of water was defined to weigh 1 kilogram and measure 1 cubic deciliter. The boiling point of water was defined as 100 degrees Celsius, and the freezing point was set at 0 C. Because of the sense involved in this measurement system, it is the standard throughout most of the world.

What is the quadratic formula used for?

The quadratic formula solves the quadratic equation, which is:ax2 + bx + c = 0The quadratic formula does this by altering the quadratic equation to allow users to solve for x directly.Though it can take time to solve, the quadratic formula is the only method for solving quadratic equations that works every time. It also holds key advantages over other methods. For example, unlike completing the square, there are no complex steps that users must remember. To solve the quadratic equation, users simply plug in the coefficients and solve the problem.Like all quadratics, the quadratic formula offer..

What are some methods for teaching addition and subtraction of integers?

An example of the objects method: for "7 plus 2," you would give the child a pile of seven M&Ms and have him or her move two M&Ms to that pile. Then, ask the child to count the total number of M&Ms.\nBy using a number line, you can introduce the concept of subtracting to get negative integers. For example, for "2 minus 7," have the child start at two and count backwards seven spots. Then, ask the child what number he or she has reached on the line.\nWhile independently solving numerical equations, the child could draw shapes to visually see how many objects should be added or taken away, or th..

How do you convert cm to mm?

Calculate length in centimetersMeasure the length of the object in centimeters using a standard ruler or measuring tape. Record the answer.Multiply the number of centimeters by 10Multiply the number of centimeters by 10. For example, if a board measures 42 centimeters, take 42 and multiply it by 10. The board measures 420 millimeters.Record the answer in millimetersRecord the converted amount, such as 420 millimeters.

What is the equation "x squared + y squared = r squared?"

A circle is a set of all points on a plane that are all a fixed distance from the center. If the circle was plotted on graph paper, the center would be located at (a,b) and the location of one point of the circumference is (x,y). It is possible to make a right-angled triangle with these two co-ordinates and a third unspecified one. Using Pythagoras' theorem, "a squared + b squared = c squared," the standard form for the equation is "(x-a) squared + (y-b) squared = r squared."

What are the steps in solving trinomial equations?

Determine the degreeIn any trinomial expression, each individual term will have a power of x (x, x^2, x^3, ...). The highest power of these three terms determines the degree of the trinomial. If there are only powers of 1 for x, it is linear. If the highest power is 2, then it is quadratic. A power of 3 within the expression is called cubic, and this list can continue indefinitely. There are few examples of trinomials with powers of 4 or higher that are completely solvable, so it is best to show what can be solved. Use algebra on linear trinomialsIf the equation turns out to be linear, it is ..
