Write a decimal number that is NOT a rational number?

1/2= 0.5 is a terminating decimal number. 1/3 = 0.33333... is a non-terminating decimal number with the digit 3, repeating. If it is non-terminating and non-recurring, it is not a rational number. Example: π is an irrational number since it has a value that is non-terminating and non-recurring.

Step-by-step explanation:

Hope This Helps!

- "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."
