How many 1-inch cubes do you need to fill a cube with an edge length of 712 foot?

Step-by-step explanation:

How many 1-inch cubes do you need to fill a cube with an edge length of 712 foot?

We must calculate a volume of a cube.

The formula of a volume of a cube with an edge s:

We know: 1 ft = 12 in. Therefore 712 ft = (712)(12) in. = 8544 in.

Substitute to the formula of a volume:

- "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."

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
