Find the area of a right triangle with a height of 8 feet and a base of 15 feet

60 ft^2

Step-by-step explanation:

The formula for area of a triangle is

A= 1/2 b*h

Substituting what we know

A = 1/2(8)*15

A = 4*15

A = 60 ft^2

- "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."
