Abby bought an 8 pound bag of doog food for $7.40. How much does the bag cost per pound? (round to the nearest hundreth)

0.92 per pound

Step-by-step explanation:

if you divide 7.40 from 8 it is 0.925. and if you multiply 0.925 by 8 it will give you 7.4. hope this helps.

step-by-step explanation:

- "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."
