Does a parallelogram have a right angle?

Quadrilaterals are closed, co-planar geometric shapes that comprise two diagonals and four sides, where all four interior angles have a sum of 360 degrees. Special types of quadrilaterals include parallelograms, rectangles, squares, rhombuses, trapezoids and kites.Parallelograms contain two pairs of opposing sides that are parallel and equally long. The opposite angles of parallelograms are also equal. Rectangles, squares and rhombuses are considered parallelograms because they share the same properties as a parallelogram.The four interior angles of rectangles and squares are all right angles,..

How do you convert 47 kg to pounds?

Know the conversion rate1 kilogram (kg) of matter is over twice as heavy as 1 pound (lb). The exact rate is 1kg = 2.2046lb, which means that 1lb = (1/2.2046)kg or 0.4536kg.Multiply by the conversion rateTo cancel out a unit, multiply by a conversion that contains the unit in the denominator. Because 1kg = 2.2046lb, you can multiply by 2.2046lb/1kg without altering the actual value of the expression.\n\nYou can use a calculator or an online conversion table to find the weight in pounds.\n\n47kg * 2.2046lb/1kg = 103.6162lb\n\nIn that equation, the kilograms cancel because 1lb*1kg/1kg = 1lb.Check..

What number is "IV"?

The first four numbers are represented by I, II, III and IV, and V represents the number five. X represents the number ten; L represents fifty; and, C is short for centum, which means one hundred in Latin. This Latin word is used in modern times in the word century, which means one hundred years.\nWhen writing Roman numerals, placing a smaller value in front of a larger value number means that the first number is subtracted from the second. For example, IV is four because V is five and I is equal to one.

What is the definition of extremes in math?

The following word problem gives a step-by-step explanation for solving this type of proportion.\nTwo picnic tables are of different sizes but have proportionate dimensions. The larger table is 15 feet wide by 10 feet long, and the smaller table is 9 feet wide. What is the length of the smaller table?\nThe proportion sets up as follows: 15/10 = 9/x. In this problem, 15 and x are the extremes, and 9 and 10 are the means. Cross multiplying yields 15x = 90, and dividing both sides by 15 yields an answer of x = 6. Each table has a proportion of 2:3 when it comes to length:width, and the smaller ta..

What are the properties of a cuboid?

A cuboid is box-like in structure. It is considered a prism because its cross-section along its length is identical. The volume of a cuboid is the product of the object's length, width and height, which can be expressed using the formula volume = length x width x height or in simpler notations, or v = lwh. Its surface area is given as a = 2wl + 2lh + 2hw, where "a" denotes the surface area.

What is factored form?

Factored form may be a product of greatest common factors or the difference of squares. For instance, the factored form of x^3 + 2x^2 - 6 = x(x+2)(x-3) and the factored form of x^2 - 16 = (x+4)(x-4)\nIt is possible to solve for x by using factored form; x^2 + 5x + 6 can be reduced to its factored form by removing the x as a common factor. This results in (x+2)(x+3). Once in the factored form, solve for x by multiplying to get zero. In the equation (x+2)(x+3) = 0, the zero factor property explains that anything multiplied by zero equals zero. This means x + 2 = 0 and x + 3 = 0. The solutions to..

How many faces does a hexagonal pyramid have?

The pyramid's base defines the pyramid in question. For example, if a pyramid has a triangle at its base, it is a triangular pyramid. If a pyramid has a pentagon at its base, it is a pentagonal pyramid. Thus, a hexagonal pyramid has a hexagon at its base. The six sides of the hexagon form six faces meeting in a point. Those six faces plus the base, which is also a face, make seven faces.

What is simplest form?

An example of reducing a fraction to its simplest form is found on Syracuse University's math website and is as follows: 8/12 = 2x4 / 3x4. In that case, the fraction can be simplified by canceling out the common factor, 4, from both the numerator and the denominator of the fraction.\n\nWhen that is done, the fraction can be reduced down to 2/3, which can be multiplied by 4 to be equal to 8/12 once again.\n\nThe best way to break down fractions into their simplest forms is to write down the prime factors of the numerators and denominators. At that point, the fraction can be rewritten showi..

What is an inverse relationship?

One example of an inverse relationship in the natural world is reproductive output. For instance, a rat may give birth to five babies that weigh 2 grams each, or it may give birth to two babies that are 5 grams each. Because the total reproductive output of the animal must remain constant, the birth weight and number of young are inversely proportional to each other. If the average baby weight increases, the average number of young must decrease.\nIn economics, the law of supply and demand is an inverse relationship. As the demand for a given product or service rises, the supply for the produc..

How is a fraction converted to a decimal?

Some fraction-to-decimal conversions will result in a non-terminating, repeating decimal. For example, when the numerator 2 is divided by the denominator 3 to convert 2/3 to a decimal, the result is 0.666666666... The "..." at the end of the decimal indicates that the numbers to the right of the decimal point will continue endlessly. This decimal conversion result, in which the digit 6 repeats itself, can also be represented either by rounding up to 0.67 or by writing it as 0.6 with a horizontal bar above the 6. In the latter representation, the decimal would be read as "zero point six repeati..
