Adobe lightroom 6 serial numbers. Rumus-rumus yang digunakan: Penjelasan: Diketahui: Lama A dan B bekerja bersama = 20 hari Lama B dan C bekerja bersama = 12 hari Lama A dan C bekerja bersam = 10 hari Ditanya: Dalam berapa hari mereka dapat menyelesaikan pekerjaan apabila mereka mengerjakan pekerjaan mereka sendiri sendiri? Jawab: Bagian pekerjaan yang bisa diselesaikan dalam 1 menit secara sendiri-sendiri A = 1/A bagian B = 1/B bagian C = 1/C bagian Kita buat persamaan dari penyataan diatas 1/A + 1/B = 1/20. Pers I 1/B + 1/C = 1/12. Pers II 1/A + 1/C = 1/10. Pers III Jumlahkan persamaan I, II, dan III 1/A + 1/B = 1/20 1/B + 1/C = 1/12 1/A + 1/C = 1/10 ------------------------------- + 2 (1/A) + 2 (1/B) + 2 (1/C) = 1/20 + 1/12 + 1/10 2 (1/A + 1/B + 1/C) = 3/60 + 5/60 + 6/60 2 (1/A + 1/B + 1/C) = 14/60 1/A + 1/B + 1/C = 14/60 × 1/2 1/A + 1/B + 1/C = 7/60. Pers IV subtitusikan persamaan IV, jika 1/B + 1/C = 1/12 1/A + 1/B + 1/C = 7/60 1/A + 1/12 = 7/60 1/A = 7/60 - 1/12 1/A = 7/60 - 5/60 1/A = 2/60 A = 60/2 A = 30 hari subtitusikan pers I, jika A = 30 1/A + 1/B = 1/20 1/30 + 1/B = 1/20 1/B = 1/20 - 1/30 1/B = 3/60 - 2/60 1/B = 1/60 B = 60 hari subtitusikan pers III, jika A = 30 1/A + 1/C = 1/10 1/30 + 1/C = 1/10 1/C = 1/10 - 1/30 1/C = 6/60 - 2/60 1/C = 4/60 C = 60/4 C = 15 hari Jadi lama mereka dapat menyelesaikan pekerjaan apabila mereka mengerjakan pekerjaan mereka sendiri sendiri adalah A = 30 hari B = 60 hari C = 15 hari.
