Matematika Kelas 7

Sebuah trapesium sama kaki panjang sisi sejajarnya 18 cm dan 12 cm, jika panjng kaki-kkinya 5 cm tentukan luas trapesium tersebut.

Tinggi trapesium = √5² - [(18-12):2]²

                         = √(25 - 9)

                         = √16

                          = 4 cm

Luas Trapesium = 1/2(18 + 12) x 4

                        = 60 cm²

Matematika Kelas 8

ASSlmlkm, nama saya lia saya pusing banget sama soal ini, padahal panjang, lebar, tinggi baloknya belum diketahui tapi kok malah itu yang ditanya.. ni soalnya " perbandingan panjang, lebar, tinggi balok ABCD.EFGH sama dengan 3:2:1 Luas permukaan balok itu sama dengan 88cm. hitunglah panjang, lebar, tinggi balok? tolong bantu saya dong soalnya mau dikumpulin besok..

Makasih mb lia atas partisipasinya !

Diket.  p : l : t = 3 : 2 : 1

          L = 88 cm²

Jawab : 

Misal p = 3n, l = 2n, dan t = n

L = 2(pl + pt + lt)

88 = 2(3nx2n + 3nxn + 2nxn)

88 = 2(6n² + 3n² + n²)

88 = 11n²

n² = 4

n = 2

Jadi p = 3x2 = 6 cm, l = 2x2 = 4 cm, dan t = 2 cm

 Students' Cheating

Students’ cheating is one of the biggest problems faced by teachers nowadays.
Despite the fact that teachers advise their students not to do dishonest acts during tests, some students still do cheating. There are many kinds of cheating that students do during the test or examination, such as looking other students’ work, put some notes under their clothes, write notes or formulas on their desks make hand signals or go to rest rooms to get the answers from their friends.
In my view, students who do cheating are committing a crime. It is a sort of taking something illegally. This crime causes negative results to the students. Students who always cheat deteriorate their mental capacity. Cheating acts also create dependence. They weaken their self confidence. Instead of preparing for the coming test, they are busy to organize notes on a piece of paper. If this awful habit continues, the students will lose their opportunity to develop their intellectual and mind.
Therefore, school should consider cheating as a very serious problem. School board and administration should go hand to overcome this matter. Honesty must be put in school’s vision. Harsh punishment must be applied to students who commit this crime.

Recycling is a collection, processing, and reuse of materials that would otherwise be thrown away. Materials ranging from precious metals to broken glass, from old newspapers to plastic spoons, can be recycled. The recycling process reclaims the original material and uses it in new products.
In general, using recycled materials to make new products costs less and requires less energy than using new materials. Recycling can also reduce pollution, either by reducing the demand for high-pollution alternatives or by minimizing the amount of pollution produced during the manufacturing process.
Paper products that can be recycled include cardboard containers, wrapping paper, and office paper. The most commonly recycled paper product is newsprint. In newspaper recycling, old newspapers are collected and searched for contaminants such as plastic bags and aluminum foil. The paper goes to a processing plant where it is mixed with hot water and turned into pulp in a machine that works much like a big kitchen blender. The pulp is screened and filtered to remove smaller contaminants. The pulp then goes to a large vat where the ink separates from the paper fibers and fl oats to the surface. The ink is skimmed off, dried and reused as ink or burned as boiler fuel. The cleaned pulp is mixed with new wood fibers to be made into paper again.
Experts estimate the average office worker generates about 5 kg of wastepaper per month. Every ton of paper that is recycled saves about 1.4 cu m (about 50 cu ft) of landfill space. One ton of recycled paper saves 17 pulpwood trees (trees used to produce paper).

Facsimile, often called fax, is away of transmitting texts and pictures over telephone lines. News services often use facsimile to send news, stories, and photographs to newspaper and television stations. Banks, law firms and other businesses use facsimile to send copies of document, to clients and other organization.
A device called a facsimile machine is used for transmitting and receiving images. Facsimile machines resemble small photocopiers. However, they are equipped with a telephone or are connected to one. To send a document, the user inserts it into the machine and dials the telephone number of the receiving fax machine. After the connection is made, an electronic scanner on the transmitting machine moves across the page and converts the image a set of electric signals. These signals travel over the telephone line to the receiving fax machine. That machine converts the electric signals back into an image of the original document and then prints a copy.
Some business people use small desktop fax machines or portable models at home or when they travel. A personal computer can also be used to send and receive documents if it is equipped with a special electronic circuit board called a fax board.
