8. Caitlyn wants to build a fence around her flower garden, which is shaped like a right triangle, if one leg of the
triangle is 9 feet long and the other is 12 feet long, how
many feet of fencing will she need to finish the project?
D a) 15 feet
Ob) 21 feet
D c) 27 feet
d) 36 feet

answer is:

1.75 pounds

g

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."
