PLEASE HELP, u will get how many marbles could fill up the jar? The jar is 15 cm

3 # of marbles, x 6.9cm height of water, Y
5 # of marbles, x 7.5cm height of water, Y
9 # of marbles, x 8.7cm height of water, Y
14 # of marbles, x 10.2cm height of water, Y
17 # of marbles, x 11.1cm height of water, Y
23 # of marbles, x 12.9cm height of water, Y

im pretty sure 8 im soo sorry if im wrong

Step-by-step explanation:

u might need to delete the other dudes answer btw can i have brainliest

- "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."
