To solve the problem, we need to determine the weight of each object by analyzing the balancing scales and the weights placed on them. Let's go through each item step by step.
1. The teddy bear
- The scale is balanced with the teddy bear on one side and a set of weights on the other.
- The weights used are: 1 kg (1000 g), 500 g, and 100 g.
- Total weight = 1000 g + 500 g + 100 g = 1600 g.
- Therefore, the teddy bear weighs
1600 g.
2. The book
- The scale is balanced with the book on one side and a set of weights on the other.
- The weights used are: 500 g, 100 g, and 50 g.
- Total weight = 500 g + 100 g + 50 g = 650 g.
- Therefore, the book weighs
650 g.
3. The fishtank
- The scale is balanced with the fishtank on one side and a set of weights on the other.
- The weights used are: 500 g and 100 g.
- Total weight = 500 g + 100 g = 600 g.
- Therefore, the fishtank weighs
600 g.
4. The tape dispenser
- The scale is balanced with the tape dispenser on one side and a set of weights on the other.
- The weights used are: 500 g and 50 g.
- Total weight = 500 g + 50 g = 550 g.
- Therefore, the tape dispenser weighs
550 g.
5. The pencil case
- The scale is balanced with the pencil case on one side and a set of weights on the other.
- The weights used are: 100 g and 50 g.
- Total weight = 100 g + 50 g = 150 g.
- Therefore, the pencil case weighs
150 g.
6. The pencils
- The scale is balanced with the pencils on one side and a set of weights on the other.
- The weights used are: 500 g.
- Total weight = 500 g.
- Therefore, the pencils weigh
500 g.
Final Answers:
- The teddy bear weighs
1600 g.
- The book weighs
650 g.
- The fishtank weighs
600 g.
- The tape dispenser weighs
550 g.
- The pencil case weighs
150 g.
- The pencils weigh
500 g.
Putting the answers in a box:
\[
\boxed{1600, 650, 600, 550, 150, 500}
\]
