7. An engineer makes different-size samples of a new material. The table shows volumes and their related masses. a. What would be the mass of 100 cubic centimeters of the material? 3000 b. What would be the mass of 500 cubic centimeters of the material? 51000 Mass in Grams (y) Volume in Cubic Centimeters (x) 990 14 25 96 9 140 leno1 adre CX|LPY. 1150 8. Higher Order Thinking The number of pizzasy, and the weight of the shredded cheese topping, x, on the pizzas have his nets a a proportional relationship. When shredded, a 50-lb block of cheese is enough to make 150 large pizzas. a. Find the constant of proportionality. 3 to derive b. How can you use the constant of proportionality to find how much cheese is on one slice of pizza, if there are 8 slices per pizza?

The constant of proportionality is An equation that relates the total cost, y, and the Cost of Lemons Number of Total Cost Lemons (x) (y) number of lemons, x, is y= 4 X. Use the equation you wrote to complete the table. 0. For every dozen bagels you buy, the cost increases $15. Which equation represents the cost, y, and the number of bagels, x? y= 1.25 +x 18 y=15x x=15y $4.20 $9.00
