What is 5/6 as a decimal?

Fractions can be easily converted into a decimal number using a calculator. If one is not available, the fraction can be converted manually using multiplication. First, the denominator, which is the (number at the bottom, is multiplied any number so that the result is a number made up of a 1 followed by 0s, such as 10, 100 or 1000. For example, in the fraction 3/4, the 4 can be multiplied by 25 to get 100. Next, the numerator, which is the top number, is multiplied by the same number. For 3/4, the 3 is multiplied by 25 to result in 75, which gives the fraction 75/100. Last, the top number is w..

What is the orthocenter of a right triangle?

Since two of the sides of a right triangle already sit at right angles to one another, the orthocenter of the right triangle is where those two sides intersect the form a right angle. The altitude of the third angle, the one opposite the hypotenuse, runs through the same intersection point. The orthocenter of an obtuse triangle lays outside the perimeter of the triangle, while the orthocenter of an acute triangle lays inside the triangle.

What is the difference between discrete and continuous data?

Data is generally classified into two categories: descriptive and numerical. Descriptive data, also called qualitative or categorical data, are represented by words that characterize a set of values while numerical data, known as quantitative data, are denoted by numbers. In discrete data, the number of possible values is countable, while continuous data is measurable and can take on infinite values. Some examples of discrete data include shoe size, set of natural numbers and number of siblings. Distance, set of real numbers and mass are some common examples of continuous data.

What is the meaning of "MDCCLXXVI"?

The year 1776 is an important date because it marked a crucial event in the history of the United States, when the Declaration of Independence was ratified by the United States government. At that time, the American Revolutionary War was in full swing.\nRoman numerals are calculated by adding the values of each of the letters together. The values are as follows: M=1000, D=500, C=100, L=50, X=10, V=5 and I=1.

What is the square root of 189?

In this case, 189 is equal to 9 — a perfect square — times 21. The square root of each factor is then taken separately. The square root of 9 is 3, and the square root of 21 cannot be simplified further and is commonly left under the radical, which is another term used to refer to the square root sign.

What are some pre-k activities for learning numbers?

By age 4, most children are able to identify one, two, three or four items. At the beginning of their fourth year, some are still learning to count to 10 or beyond, and they sometimes mix up their numbers.\nIn geometry, the pre-K student is learning the names of geometric shapes including circles, squares and triangles. Activities requiring the matching of common shapes are appropriate at this age level. A 48 month-old child sometimes draws using a single shape without combining other shapes to complete the picture. As he grows toward the end of his fourth year, he is more likely to combine sh..

How do you use multiplication grids?

When multiplying a two-digit number by another two-digit number, both must be partitioned and placed into the grid. Multiply the numbers linked to each box together, and add all of the answers together to find the result of the multiplication.\nFractions and decimals can also be multiplied using the multiplication grid. If multiplying a number by 1 1/2 or 1.5, make a partition by separating the 1 from the 1/2 or 0.5. It is also possible to perform algebraic multiplications using this method.\nMultiplication grids break down difficult multiplication into more manageable numbers. The method is u..

How could you make a dollar using 25 coins?

Other coin combinations to make a dollar include: 7 dimes, 3 nickels and 15 pennies; 1 quarter, 3 dimes, 6 nickels and 15 pennies; 2 quarters, 3 dimes and 20 pennies; 1 half dollar, 2 dimes, 2 nickels, and 20 pennies.\nThere are many obsolete coins, with odd values, that would allow for more combinations. Wikipedia lists some of these obsolete coins, such as: the half-cent, two-cent, three-cent and twenty-cent pieces. These coins can be found in collections; however, they are no longer considered legal tender, according to Wikipedia.

How do you divide polynomials?

Write the polynomials in long division formWrite the denominator first, and draw an open box to the right of it. Write the numerator inside the box. Divide the numerator by the denominatorDivide the first term of the numerator by the first term of the denominator. Write the answer on the line above the numerator. Multiply that answer with the denominator. Write this result below the numerator, and subtract. Divide the result by the first term of the denominator, then write the answer on the line above the numerator. Multiply that answer with the denominator, and subtract the result from the nu..
