Eric is baking a cake the recipe calls for 2 1/2 pounds of flour for every 1/4 cup of sugar. How many pounds of flour should Eric use for 5 cups of sugar?

50 pouns

Step-by-step explanation:

Since he require 2 1/2pound for 1/4 cup of sugar so for 1 cup of sugar we will multiply it by 4. So 10 pound of flour will be require for 1 cup of sugar, multiply by 5 to get the answer which is 50.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
