Answer 1

1. 3/3 + 2/3 = 5/3 (a)

2. (4 x 3600) + (2 x 1500) = 14.400 + 3.000 = 17.400 (d)

3. 2/(2+3) x 180 = 2/5 x 180 = 72

3/(2+3) x 180 = 3/5 x 180 = 108 (d)

4. sudut AOC = 180 - 30 = 150 (a)

5. keliling = 4a + 3a + 2a

45 = 9a

a = 5(a)

6. 7 (c)

7. 5 (a)

8. jumlah siswa = 5+10+20+15+10+5 = 65 (a)

9. lemari kedua = 148 / 4 = 37 (d)

10. (4.700.000 - 4.350.000) / 4.350.000 x 100% = 350.000/4.350.000 x 100% = 8,05% (d)

11. AB = √(AO²+OB²)

AB = √(3² + 4²) = √(9 + 16) = √25 = 5

keliling = 4 x AB = 4 x 5 = 20 (a)

12. 20 pekerja = 45 hari

18 pekerja = (45 x 20) / 18 = 50 hari (a)

13. (15.850.000 x 120%) / 24 = 19.020.000 / 24 = 792.500(b)
