The square pyramid has a volume of 288 cubic inches. what is the value of x?

Step-by-step explanation:

the formula for the volume of a square pyramid is:

where

is the area of the base (the area of the square)

and if the height of the pyramid

---------

the length of the side of the square is , so the area of the base of the pyramid is:

and we already know the height in terms of x:

and the Volume:

so we subtitute all of this in the formula for volume:

and finally we clear for

the value of x is 12 inches.

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

- "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."
