What is 5.4772 rounded to the nearest tenth???

5.5

Step-by-step explanation:

In the tenths place is the 4, so you have to round from the place behind it, the 7. You round up to 5 because 7 is greater than 5.

:>

Step-by-step explanation:

In 5.4772, 4 represents your tenths place.

So, now you round based on the number beside 4 which is 7. Since 7 is greater than 5, you will round 4 up one.

So, 5,4772 becomes 5.5

5.5 is  5.4772 rounded to the nearest tenth,

- "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."

answer:   y=2x-3
