How do you figure out the square footage of an area?

For rectangles and squares, after the length and width are measured, the length and width are then multiplied together to obtain the square footage. For a triangle, the base and height are measured, and then the base and height are multiplied by one-half. Note that for triangles, any side of the triangle can be considered the base for measurement purposes.\nFor circles, after the diameter is measured, the diameter is divided by two to get the radius, and then the radius is multiplied by 3.14 to determine the square footage. For an irregular space, the space is split into known shapes and then ..

How do you find the vertical asymptotes of a rational function?

Factor the rational expressionStarting with an example expression such as (x^2 + x -12)/(x^2 - 3x - 10), factor the expression down to basic terms. Determine which factors of the constant would result in the middle term when using the FOIL method to multiply binomials.Check the factoringMultiply the binomial to check it by using the FOIL method: multiply first terms, then outside terms, then inside, then last.Rewrite the expressionRewrite the expression in its simplest form. The example would be written as (x - 3)(x + 4)/(x + 2)(x - 5).Find the rational zerosRational zeros are the values of th..

What is the definition of "translation" in geometry?

Translations differ from reflections and rotations. In a reflection or rotation, the points of the shape are moved varying distances based upon the distance the original points were from a given line or point outside the shape. Translations preserve the orientation of the angles to one another. For this reason, a translation is considered a direct isometry or a type of transformation that preserves the length of all sides and the placement of the angles in relation to one another.

What shape is an oblong?

An oblong can also describe any shape that is longer than it is wide. For instance, an oval is also considered oblong. Some common examples are a piece of paper or a spaghetti squash. The word originated from the French word "oblonge," which came from the Latin word "oblongus." It first came into English in Middle English. Essentially, the Latin word means "long," from "longus" and "towards," from "ob"; in other words, leaning toward being long rather than short.

What is an 8-sided polygon called?

Octagons are polygons with eight sides. The root word oct- indicates the number eight, as in octopus (which has eight legs). The stop sign form of the octagon has its sides parallel to the x- and y-axes; octagons can also be oriented with its vertices along these axes. \n\nAn octagon is a two-dimensional polygon. For three-dimensional shapes (polyhedras), a shape with eight faces is called an octahedron. This include shapes such as a hexagonal prism.

How do you calculate frequency?

There is another formula that states that the angular frequency (ω) is equal to 2 multiplied by pi and the frequency, or ω = 2πf. From this formula, one can calculate frequency (f) by dividing both sides of the equation by 2π to find that f= ω/2π.\n\nThe frequency (f) is the number of waves per unit time, and its measurement unit is in Hertz (Hz).\n\nThe wavelength (λ) is the distance between one point on a wave to the exact same point on the adjacent wave, and its measurement is in meters. The wave velocity (v) measurement is meters per second. Likewise, the period (T) of a wave is th..

How do you convert 600 grams into cups?

A cup is a unit of capacity used for measurement. A cup is equal to 8 fluid ounces (oz.), 237 milliliters (ml), 16 tablespoons (tbsp.) and 1 half-pint. Cups are frequently used as measuring units in baking and cooking recipes. A gram is a metric unit of mass or weight. A gram is equal to 15.432 grains and 1/1000 of a kilogram (kg). Grams are frequently used to measure small amounts of dry material.

How do you teach division?

"Sharing" is a term that is commonly used to introduce division for the first time, because it is a term that most young students are familiar with. Making this lesson a game keeps students interested through the difficulties. Present the students with a some small objects and a set of glasses. With the equation in mind, instruct them to divide the correct number of objects into the glasses. Explaining the equations orally before writing them down gives the student a basic understanding of the way division looks and operates.\nTo learn division easily, it is important that the students are alr..

How do you find the nth term of fractions?

Find the pattern in the numeratorFirst find the pattern in the numerators of the fraction sequence. It is helpful to make a chart. For example, in the fraction sequence 2/3, 3/5, 4/7, 5/9, the numerator starts with 2 and then increases by 1 each time. Find the pattern in the denominatorUse the same process to find the pattern for the denominator. To continue the example, the denominators start with 3 and increase by 2 each time. Write the general expressionWrite a general expression for the fraction sequence that shows the pattern, using "n" as the variable. The example numerator sequence is n..

What is the square root of 252?

The exact value of the square root of 252 can be found by using the radical function on a calculator. It can also be solved via simplification by factoring out the square of a whole number divisor. Since 252 is equal to 36 x 7, the square root of 252 is equal to the square root of 36 times the square root of seven. As the square of a whole number, the square root of 36 can be rewritten as plain 6, resulting in the final form of 6 x square root (7).
