Alas sebuah limas berbentuk segitiga siku-siku dengan panjang sisi 10cm, 26cm, dan 24cm. Tentukan volume limas tersebut

Vol limas = (Luas alas x tinggi):3 Luas alas=(10x24):2=120 cm persegi karena tingginya tidak diketahui, kita misalkan t cm sehingga volumnya = 120t:3= 40t cm kubik

bagaimana cara belajar supaya mudah memahami semua teori b.inggris?

Hal yang paling pokok dalam Anda belajar adalah menyukai mata pelajaran (bahasa Inggris)) itu dulu. Kemudian cara memahami semua teori bahasa Inggris adalah sebagai berikut.
1. Baca berulang - ulang materi yang sedang Anda pelajari, misalnya 'Grammar', 'Genre' , 'Functional texts', dll.
2. Kemudian praktekkan teori yang anda pelajari sesuai dengan pemahaman Anda.(practice...practice and practice!)
3. Konsultasikan pemahaman dan hasil latihan Anda tadi kepada guru atau pembimbing yang qualified(orang yang pintar dan paham tentang bahasa Inggris).
4. Kalau ternyata masih terdapat kesalahan, coba dan coba lagi sampai Anda benar - benar paham sehingga bisa menerapkan teori yang Anda miliki dengan benar.
Note: Pepatah Inggris mengatakan "I SEE I KNOW, I DO I UNDERSTAND"
Jangan pernah menyerah untuk meraih keberhasilan, kalau toh awalnya belum paham dan sering salah, itu adalah bagian dari proses belajar untuk akhirnya menjadi pintar.
"Competition is painful but it will give you a great success"
GOOD LUCK.

Alas sebuah akuarium berbentuk persegi panjang dgn panjang 1 meter dan lebar 0.5 meter. Jika 2/3 bagian akuarium berisi air sebanyak 200 liter, tentukan tinggi akuarium

Vol akuarium (balok) = luas alas x t 200 dm^3= (2/3)(10 dmx5dm) t 200 dm^3= 100/3 t dm^2 t= (200x3):100 dm = 6 dm

apa yang dimaksud GENRE ?

Genre adalah jenis teks.
Untuk level SMP, Genre yang harus dipelajari terdiri dari teks Narrative, Recount, Descriptive, Procedure dan Report.
Keterangan :
Jadi, pembelajaran bahasa Inggris sekarang ini berdasarkan pada jenis teks(Genre), bukan lagi Tema seperti dulu. Artinya, pembelajaran saat ini lebih menitikberatkan pada pemberian kemampuan berbahasa atau 'lifeskill' kepada siswa, sehingga mereka dapat survive dalam kehidupan bermasyarakat dan dapat menerapkan dalam kehidupan siswa.
Sebelum mempelajari Genre, segala pengetahuan kebahasaan (Grammar dan Vocab) harus dipelajari agar siswa mampu bermonolog dan menulis sesuai dengan Genre yang akan diungkapkannya.

bnErnya gimana sih cara bElajar matematika yang nyenengin waktu mau ulangan umum??pdhl kan itu hari-hari yang bikin students pada "mumet"....????

Cara belajar yang nyenengin tergantung dari kesenangan Anda apa? Misalnya musik, belajarlah sambil dengerin musik, kalau senengnya sepi, belajarlah disaat-saat sepi, misal tengah malam dsb. Jangan Anda memaksa untuk bisa menjawab saat itu juga, tetapi istirahatlah sebentar dan gunakan untuk olah raga kecil, misal jalan ditempat, meliukkan badan, dsb agar badan dan pikiran jadi fresh. Jangan stress, be rilex, tenanggggg, aku pasti bisaaa...gitu lho. Trims semoga bisa membantu Anda. Selamat mencoba.

BERIKAN CONTOH TEXT REPORT DAN TEXT DESKRIPTIF YANG SALING BERHUNUNGAN !

Teks report dan deskriptif memang hampir sama, tetapi mereka masing-masing berdiri sendiri. Untuk yg berhubungan jarang terjadi. Pasti salah satu saja yg dimunculkan.
Report dan deskriptif memiliki generic structure yg hampir sama yaitu : Identification - description. (untk deskriptif) dan general classification - description
Yg berbeda kalau report yg didiskripsikan sesuatu yg bersifat umum sedangkan descriptive mendeskripsikan satu benda/tempat/binatang secara spesifik
Contoh : Report : 'Mountain' isi teksnya akan menjelaskan apa yg dimaksud dg gunung secara umum.
Descriptive : ' Mount Merapi' isi teksnya menceritakan ttg gunung Merapi saja dan segala hal yg spesifik ttg gunung Merapi tsb.
