Which of the following could be the weight of the tennis ball? A. 125 g B. 120 g C. 75 g D. 50 g

Answer

To analyze the weights, we first find the weight of the toy bear. 1. In the first balance, the toy bear is weighed against a weight of 100 g. This means the weight of the toy bear equals 100 g. - Toy Bear = 100 g 2. In the second balance setup, the toy bear (100 g) is weighed against the tennis ball and a weight of 200 g. This situation can be expressed mathematically as: - Toy Bear + Tennis Ball = 200 g - 100 g + Tennis Ball = 200 g 3. To find the weight of the tennis ball, we isolate it: - Tennis Ball = 200 g - 100 g - Tennis Ball = 100 g Now that we know the tennis ball weighs 100 g, we can see which of the provided options could represent the weight of the tennis ball. The options given are: - A. 125 g - B. 120 g - C. 75 g - D. 50 g Since the tennis ball was determined to weigh 100 g and none of the answer choices are 100 g, we must reconsider the potential for approximate weights. However, since 100 g is not provided in the options, we recognize that there are no correct answers in the given choices. Hence, none of the options A, B, C, or D could be the weight of the tennis ball based on the calculations. Conclusively, the proposed answer must be stated outright based on this reasoning.
