(19459007) Counting the Number of Sections - The Basic Mathematical Formula has explained about Definition, Formula And Sample Set of Sections . To increase your knowledge of the material, this time will be discussed further material about himounan section that is about how to determine or count the many subsets of a set. As a first step, try looking at the picture below: From the table we can see that there is a relationship between the number of members of a set with the number of subsets. Therefore, we can draw the conclusion that the sum of subsets of a set is 2n where n is the sum of all members of the set. In searching and counting the number of subsets that have members as many as n we can use the pattern of numbers on the pascal triangle as below: [1945909] If you observe, on the pattern of blangan Pascal above, the number in the middle is the result of the sum of the numbers that are above it. The pattern of these pascal triangular numbers can be described as: The subsection of a, b, c, d which has a member of 0 there is 1: ] The subsection of a, b, c, d which has a member of 1 there are 4: a, { (1945909) The subsection of { A, b, c, d which has 2 members there are 6: b, a, c, a, d, a, B, c, b, d, c, d The set Part of a, b, c, d which has 3 members there are 4: a, b, c, b, c, d, c, d, a, d, a , B


The subsection of a, b, c, and which has 4 members there is 1:
a, b, c, d

That is how Counts The Number of Subspaces of a Set that you can try to do. Hopefully it will make it easier for you to work on problems related to the set matter.

Units of Size The number of Lusin, Gross, Rim, and Kodi

Unit Size The Number of Lusin, Gross, Rim, And Kodi - When carrying out your daily activities you must have heard some terms like Lusin, Gross, Rim, and Kodi in mathematics the term is called a unit of measure of quantity or quantity. This unit is commonly used to express the number of items or objects. For those of you who do not know or have not memorized by the size of the unit, let us study it together by listening to the discussion The Basic Mathematical Formula on the following unit size sums: The most commonly used unit of measure quantities is : 1 dozen = 12 pieces 1 gross = 144 pieces = 12 Lusin 1 score = 20 pieces ] 1 rim = 500 glue Bar The use of units of measure of the number of Lusin, Gross, Rim, and Kodi The above sizes are usually used in accordance with certain types of goods, for example: Lusin The term dozen is more often used to express the number of items such as glasses, plates, spoons, jars, and so on.

Have you already read posts Mathematical Formulas Dasa r regarding How to Calculate Distance point to point, Line, and field ? if not, you should read it first so that you can more easily understand Sample Questions and Discussion How to Calculate Distance Point to Line In Cube which will be described below: Sample Questions and Discussion How to Calculate Distance point to Line In Cube Example Problem 1 Unknown length ABCD.EFGH ribs cube is 6cm. Then calculate the distance: a) .period D to line BF b) .period B to line EG Solved: a ) .Agar easier to answer that, let us look at the picture below: From the above picture we can see that the distance of the point D to the length of the diagonal line BD BF is to be determined by using Teor ema Pythagoras or formula. Let's finish with the theorem of Pythagoras first: BD2 = AB 2 + AD 2 BD2 = 6 2 + 6 2 BD2 = 72 BD = √72 = 6√2 cm beikut if we look for it by using the formula: d = s...

Example Problem Arithmetic Social About Discount / Rebate

Example Problem Arithmetic Social About Discount / Rebate - the meaning of rebates are rebates granted to a product or service. We are more familiar with rebates as a discount. You'll often see at the supermarket or supermarket there are a lot of rebates or discounts, it is an example of a rebate. If you are curious about how to calculate the price cuts, the Mathematical Formulas Basic will give his review to you through examples to the following: Example Problem Discussion and Arithmetic Social About Rabat Example Problem 1 Melly want to buy a dress for Rp 120,000. It turned out that the clothes receive a rebate of 20%. What is the size of the rebate? Answer: clothes Price: Rp 120,000 Rabat: 20% x 120,000 = 20/100 x 120,000 = 24,000 Thus, rabatnya amounted Rp.24.000 Example Problem 2 [1945901million] A Shop, gives a 5% discount for every purchase math book. If a math book has a price of Rp. 85,000. what is the price of the book after the discount?...
