Cynthia besch wants to buy a rug for a room that is 29 ft wide and 30 ft long. she wants to leave a uniform strip of floor around the rug. she can afford to buy 756 square feet of carpeting. what dimension should the rug have?

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round 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."
