haley is giving her puppy a bath. she fills up the bathtub, washes the puppy, and then empties the tub. which graph could show the amount of water in the bathtub over time?
Answer
Explanation:
Step1: Analyze filling - stage
When Haley fills up the bathtub, the amount of water in the tub increases over time. So the graph should have a positive - sloped line segment initially.
Step2: Analyze washing - stage
While she is washing the puppy, the amount of water in the tub remains constant. So the graph should have a horizontal line segment.
Step3: Analyze emptying - stage
When she empties the tub, the amount of water in the tub decreases over time. So the graph should have a negative - sloped line segment at the end.
Answer:
The first graph (the one on the left) shows an increase in water amount (positive - slope), then a constant amount (horizontal line), and then a decrease in water amount (negative - slope), which matches the described process.
