Bagaimana menghitung volume bidang 4 beraturan segitiga sama sisi?
bidang empat beraturan adalah nama lain dari limas segitiga beraturan sehingga cara menghitung volumnya juga sama yaitu V = 1/3 x luas alas x tinggi. Alas bidang empat beraturan berupa segitiga sama sisi , sehingga dalam menghitung luasnya dapat menggunakan berbagai rumus luas segitiga yang telah Hamboro pelajari di kelas X ( tergantung pada unsur yang diketahui dalam segitiga tersebut ). Kalau masih belum jelas, coba kirim lagi ke kbs soal yang sedang Hamboro hitung volumnya. Kami tunggu ya ....
Bu Guru , tolong bantu saya ya:
Sebuah garis PQ , panjangnya 2,1 cm dibagi oleh titik X shg PX/XQ = 4/3 dan oleh titik Y shg PY/YQ = - 4/3. hitunglah XY ! Terima kasih bu!
Situasi I
PX : XQ = 4 : 3 berarti PX = (4/7) x 2,1 cm = 1,2 cm dan XQ = ( 3/7 ) x 2,1 cm = 0,9 cm.
Situasi II
PY : YQ = - 4 : 3 karena perbandingan bernilai negatif berarti arah ( letak ) PY berlawanan arah dengan letak YQ. Kalau di gambar akan terlihat dalam garis berturut turut dari kiri titik Y, Q kemudian P. Coba kamu buat sketsanya.
YQ = 3 bagian , YP = 4 bagian sehingga QP = 1bagian = 2,1 cm ( dari soal ) sehingga YQ= 3 bagian = 3 x 2,1 cm = 6,3 cm.
Situasi I dan II digabung kita dapatkan XY = YX = YQ + QX = 6,3 cm + 0,9 cm = 7,2 cm.

Donkey in the well.
A short, important story.
(Author unknown)
One day a farmer's donkey fell down into a well. The animal cried piteously for hours as the farmer tried to figure out what to do. Finally he decided the animal was old and the well needed to be covered up anyway, it just wasn't worth it to retrieve the donkey.
He invited all his neighbors to come over and help him. They all grabbed a shovel and began to shovel dirt into the well. At first, the donkey realized what was happening and cried horribly. Then, to everyone's amazement, he quieted down.
A few shovel loads later, the farmer finally looked down the well and was astonished at what he saw. With every shovel of dirt that hit his back, the donkey was doing something amazing. He would shake it off and take a step up.
As the farmer's neighbors continued to shovel dirt on top of the animal, he would shake it off and take a step up. Pretty soon, everyone was amazed as the donkey stepped up over the edge of the well and trotted off!
Life is going to shovel dirt on you, all kinds of dirt. The trick to getting out of the well is to shake it off and take a step up. Each of our troubles is a stepping-stone. We can get out of the deepest wells just by not stopping, never giving up! Shake it off and take a step up!

tolong minta keterangan tentang passive voice dan beserta rumus-rumusnya dalam semua bentuk tenses. terima kasih
Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action.
Example: My bike was stolen.
In the example above, the focus is on the fact that my bike was stolen. I do not know, however, who did it.
Sometimes a statement in passive is more polite than active voice, as the following example shows:
Example: A mistake was made.
In this case, I focus on the fact that a mistake was made, but I do not blame anyone (e.g. You have made a mistake.).
Subject + finite form of to be + Past Participle (3rd column of irregular verbs)
Example: A letter was written.
When rewriting active sentences in passive voice, note the following:
| Tense | Subject | Verb | Object | |
|---|---|---|---|---|
| Simple Present | Active: | Rita | writes | a letter. |
| Passive: | A letter | is written | by Rita. | |
| Simple Past | Active: | Rita | wrote | a letter. |
| Passive: | A letter | was written | by Rita. | |
| Present Perfect | Active: | Rita | has written | a letter. |
| Passive: | A letter | has been written | by Rita. | |
| Future I | Active: | Rita | will write | a letter. |
| Passive: | A letter | will be written | by Rita. | |
| Hilfsverben | Active: | Rita | can write | a letter. |
| Passive: | A letter | can be written | by Rita. | |
| Tense | Subject | Verb | Object | |
|---|---|---|---|---|
| Present Progressive | Active: | Rita | is writing | a letter. |
| Passive: | A letter | is being written | by Rita. | |
| Past Progressive | Active: | Rita | was writing | a letter. |
| Passive: | A letter | was being written | by Rita. | |
| Past Perfect | Active: | Rita | had written | a letter. |
| Passive: | A letter | had been written | by Rita. | |
| Future II | Active: | Rita | will have written | a letter. |
| Passive: | A letter | will have been written | by Rita. | |
| Conditional I | Active: | Rita | would write | a letter. |
| Passive: | A letter | would be written | by Rita. | |
| Conditional II | Active: | Rita | would have written | a letter. |
| Passive: | A letter | would have been written | by Rita. | |
Rewriting an active sentence with two objects in passive voice means that one of the two objects becomes the subject, the other one remains an object. Which object to transform into a subject depends on what you want to put the focus on.
| Subject | Verb | Object 1 | Object 2 | |
|---|---|---|---|---|
| Active: | Rita | wrote | a letter | to me. |
| Passive: | A letter | was written | to me | by Rita. |
| Passive: | I | was written | a letter | by Rita. |
As you can see in the examples, adding by Rita does not sound very elegant. That’s why it is usually dropped.
Personal Passive simply means that the object of the active sentence becomes the subject of the passive sentence. So every verb that needs an object (transitive verb) can form a personal passive.
Example: They build houses. – Houses are built.
Verbs without an object (intransitive verb) normally cannot form a personal passive sentence (as there is no object that can become the subject of the passive sentence). If you want to use an intransitive verb in passive voice, you need an impersonal construction – therefore this passive is called Impersonal Passive.
Example: he says – it is said
Impersonal Passive is not as common in English as in some other languages (e.g. German, Latin). In English, Impersonal Passive is only possible with verbs of perception (e. g. say, think, know).
Example: They say that women live longer than men. – It is said that women live longer than men.
Although Impersonal Passive is possible here, Personal Passive is more common.
Example: They say that women live longer than men. – Women are said to live longer than men.
The subject of the subordinate clause (women) goes to the beginning of the sentence; the verb of perception is put into passive voice. The rest of the sentence is added using an infinitive construction with 'to' (certain auxiliary verbs and that are dropped).
Sometimes the term Personal Passive is used in English lessons if the indirect object of an active sentence is to become the subject of the passive sentence.

berapakah hasil
0/0 = ? mengapa ?
0/1 = ? mengapa ?
1/0 = ? mengapa ?
pengertian dari a/b =c <=> a = bc
0/0 = tak tentu karena 0/0 = c <=> 0 = 0 x c berapapun nilai c
0/1 = 0 karena 0 = 0 x 1
1/0 = tak terdefinisi karena 1/0 = c <=> 1 =/= 0 x c
berapakah hasil
0/0 = ? mengapa ?
0/1 = ? mengapa ?
1/0 = ? mengapa ?
0/0 = tak tentu ( lihat definisi buku ensiklopedi matematika st nagoro)
0/1 = 0
1/0 = taktentu
