An empty 5-gal water jug weighs 0.75lb. With 3c of water inside, the jug weighs 2.25lb. Predict the weight of the jug with 5c of water inside
2.25 - 0.75 = 1.5 weight of 3 cups of water
I'll be glad to check your answer.
To predict the weight of the jug with 5 cups of water inside, let's break down the problem step by step.
First, we need to find the weight of the water in the jug. Given that the weight of the empty jug is 0.75 lb and the jug with 3 cups of water weighs 2.25 lb, we can find the weight of the water.
The weight of the water in the jug is the difference between the weighted jug and the empty jug:
Weight of water = Weight of jug with water - Weight of empty jug
In this case, it would be:
Weight of water = 2.25 lb - 0.75 lb = 1.5 lb
Now, knowing that 3 cups of water weigh 1.5 lb, we can calculate the weight of 1 cup of water:
Weight of 1 cup of water = Total weight of water / Total number of cups of water
Weight of 1 cup of water = 1.5 lb / 3 cups = 0.5 lb
Finally, to predict the weight of the jug with 5 cups of water, multiply the weight of 1 cup of water by the number of cups:
Weight of jug with 5 cups of water = Weight of 1 cup of water * Number of cups of water
Weight of jug with 5 cups of water = 0.5 lb * 5 cups = 2.5 lb
Therefore, the weight of the jug with 5 cups of water inside would be 2.5 pounds.
