Section C: Word Problems (25 marks)
26. Answer: 15.23 kg
Working: Total weight = 8.45 + 6.78 = 15.23 kg
27. Answer: $46.75
Working: Money left = 45.75 = $46.75
28. Answer: 3.9 m
Working: Length of each piece = 27.3 ÷ 7 = 3.9 m
29. Answer: 31.05 kg
Working: Total weight = 3.45 × 9 = 31.05 kg
30. Answer: x = 48°, Acute triangle
Working:
- Sum of angles in triangle = 180°
- x + 58 + 74 = 180
- x + 132 = 180
- x = 180 - 132 = 48°
All angles (48°, 58°, 74°) are less than 90°, so this is an acute triangle.
