Is 563 divisibly by 4

No

Step-by-step explanation:

To be divisible by 4 the last two digits have to be divisible by 4

so

is 63 divisibly by 4?

no

because is odd and four is even

so we can conclude that 563 is not divisible by 4

563 is not divisible because if you divide you get 187.6667777 and for it to be divisible it needs to be a whole number

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."
