Question

tony put some ice cubes into a pitcher with 1,000 grams of lemonade. the pitcher and left it on his table. when he came back a few hours later, there had been a change. all of t had melted and mixed into the lemonade. the pitcher had 1,500 grams of lemon complete the bar graph to show the mass of the ice. masses before and after the change

Explanation:

Step1: Find mass of ice

The total mass after (1500g) equals lemonade before (1000g) plus ice mass. Let \( m \) be ice mass. So \( 1000 + m = 1500 \). Solve: \( m = 1500 - 1000 = 500 \) grams.

Step2: Draw ice bar

On the bar graph, for "ice" under "Before", draw a bar reaching 500 grams (matches the y - axis scale: 0, 250, 500, etc.).

Answer:

The mass of the ice is 500 grams, and the bar for ice in the "Before" section of the graph should be drawn to the 500 - gram mark on the y - axis.
