Can y’all help my plesss

The right rectangular prism has length= 5 and width = 6.25 which is option B).

Step-by-step explanation:

The Formula for volume of right rectangular prism is given as :

Volume = length× width× height.

The given information are :

To find length and width :

Substitute volume = 250 and height = 8 in the above formula,

Volume of right rectangular prism = length× width× height.

250 = length× width× 8

length× width = 250/8

length× width = 31.25  (1)

Now, substitute the given options in the equation(1) and check which values of length and width satisfies the equation.

Option A) l= 5 and w= 6

length× width = 31.25

5×6 = 30 (less that 31.25)

Option B) l= 5 and w= 6.25

length× width = 31.25

5×6.25 = 31.25 (satisfies the equation)

Option C) l= 5.25 and w= 6

length× width = 31.25

5.25×6 = 31.5 (greater that 31.25)

Option D) l= 5.5 and w= 6.2

length× width = 31.25

5.5×6.2 = 34.1 (greater that 31.25)

- "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."
