(19459007) Understanding The Set of Parts - Previous ] The Basic Mathematical Formula has discussed the matter of The set which became one of the materials taught in junior high. In the set, there is a term called the subsets. A simple subset can be defined as a condition in which elements of a set belong to elements of another set. For example, set M can be said to be a subset of N when every element in set M belongs to the umusr in the set N. Now consider the following picture: [1945909] From the picture above we can see that there are three different sets of sets A, B and C. If you note, of course you can see that members are owned by The sets A (1, 2, and 3) are also included in the members in the set C ( 1, 2, 3, 4, and 6). In such a case, we can conclude that Set A is a subset of the set C. The condition can be denoted as A ᴄ C or C ᴐ A . Now look at the picture below: From the figure, we can observe together that there is a member of set B which also belongs to the set member C (4, 5). However, there are members of set B that are not members of set C (6). So in such an event the set B can not be said to be a subset of C because not all of its members exist in the set C. The event can be represented as B c C. [19459020 The Formulas and Sample Set Part To understand more about subsets, now consider the example set below: S = {all seventh graders in junior B = {all students of grade 7A at SMP Tunas Mekar L = all female students in grade 7A M = {all male students] (19459013) From some of the above sets, we can infer some descriptions Such as: 1. The set L and M are subsets of set A because every member present in the set L and M is definitely included in the set K (female students And men in grade 7A are all students in grade 7A) 2. The set K is a subset of the set S because every member in the set K belongs to Members of the set S (All seventh grade students are definitely included into all 7th grade students in Tunas Mekar Junior High School) 3. The set L is not a subset of the set M (since members of the set of male students may not be included in the female student association) vice versa.

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?...
