WILL GIVE BRAINLIEST TO FIRST PERSON WHO ACTUALLY TRIES!!! What is the length of the unknown leg of the right triangle rounded to the nearest tenth of a foot?

Around 8.8

Step-by-step explanation:

This problem requires the Pythagorean Theorem. We are given the hypotenuse and a leg, so we can plug in what we know.

.25

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."
