Concrete is often used to surface roads. Concrete is mostly a mixture of water, rocks or aggregate, and a powdery substance of calcined lime (also called cement). To create a strong, durable concrete, the proportion of the ingredients is important. A mixture that does not have enough cement paste will be difficult to distribute and will produce rough surfaces. A mixture with too much cement paste will result in a smooth surface, but resulting concrete can easily crack.

The table shows a concrete mixture used to pave 50 yards of street. Fill in the amount of each ingredient needed to pave 300 yards of street.

The table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe: number of cups of cereal number of cups of raisins 8 2 12 3 16 4 molly plotted an equivalent ratio as shown on the grid below: a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the x-axis values are 0, 20, 40, 60, 80,100. the vertical axis label is raisins in cups. the y-axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 40,20. which of these explains why the point molly plotted is incorrect? (a) if the number of cups of cereal is 40, then the number of cups of raisins will be10. (b)if the number of cups of raisins is 40, then the number of cups of cereal will be10. (c) if the number of cups of cereal is 40, then the number of cups of raisins will be 80. (d) if the number of cups of raisins is 40, then the number of cups of cereal will be 80.
