ass wr wb,mau nanyarumus dari suku ke-n dari barisan 7,12,17,22,... itu apa ya?trims bagi yg menjawab...
Un = a + (n-1) b
= 7 + (n-1)5
= 7 + 5n -5
= 5n + 2
Berapakah banyaknya bilangan ganjil yang terdiri dari 3 angka? tolong jelaskan caranya!
Barisan yang dimaksud : 111, 113, 115, 117, ..., 999
Un = a + (n-1)b
999 = 111 + (n-1)2
999 = 111 + 2n - 2
999 - 109 = 2n
890 = 2n
n = 450
Sebuah benda logam berbentuk kubus dimasukan kedalam bejana berbentuk balok sehingga benda tersebut tenggelam dan permukaan air menjadi naik. jika panjang rusuk benda logam 3 cm dan alas beja berukuran 6cm x 5 cm, berapa tinggi air yang naik?

Budi meminjam uang di Bank sebesar Rp.5.100.000,00 untuk pembelian komputer. angsuran setiap bulan Rp. 165.000,00 dalam jangka waktu 4 tahun. berapa presentase bunga pinjaman tersebut?
Uang pinjaman Rp.5.100.000,00
angsuran setiap bulan Rp. 165.000,00
waktu = 4 tahun = 4 x 12 bulan = 48 bulan
Jumlah uang pinjaman = 48 x Rp. 165.000,00
= Rp. 7.920.000
Bunga dalam 4 tahun = Rp. 7.920.000 - Rp.5.100.000,00 = Rp. 2.820.000
Bunga dalam 1 tahun = Rp. 2.820.000 : 4
= Rp. 705.000
Presentase bunga dalam 1 tahun = Rp. 705.000 : Rp.5.100.000,00 x 100% = 13,82%
terdapat dua barisan bilangan : a. 1,1,2,3,5,... b. 2,6,12,20,30,... mengapa kedua barisan bilangan tersebut bukan merupakan barisan aritmetika? JELASKAN
a. barisan 1: a. 1,1,2,3,5,... beda tiap suku besarnya tidak menentu jadi bukan barisan bilangan ARITMATIKA, karena barisan bilangan aritmatika mempunyai beda tiap sukunya tetap. Barisan tsb adalah barisan bilangan FIBONACCI.
b. 2,6,12,20,30,... beda tiap suku besarnya tidak menentu tetapi jika beda tiap suku diteruskan hingga beda pada tingkat ke-2, maka akan memiliki beda tetap yaitu 2, jadi barisan bilangan itu termasuk barisan bilangan ARITMATIKA berderajad dua ( tingkat dua)

Hongkong
In Hong Kong, the students are not always able to answer questions about their country. Although Hong Kong is their country, they have had little opportunity to go on excursions. Most of them cannot afford the time or money needed for such trips. Since, they do not know much about Hong Kong’s history and its culture, they have always had to write to the Hong Kong Tourist Association for information.
To give such students sound knowledge about Hong Kong, The Tourist Association decided to start the student ambassador programme. The programme has been carried out for eight years. Young men and women who are going overseas for further studies are selected to undergo a special course dealing with the history, culture and lifestyle of Hong Kong.
Through visits factories, government departments and other places of interest, the young people receive ample information which will enable them to answer a wide range of questions asked by persons abroad.
