Taylor wants to paint his rectangular deck that 42 feet long and 28 feet wide. a gallon of paint covers about 350 square feet. how many gallons of paint will taylor need to cover the entire deck?

Let L be the length of the deck = 42 feet

Let W be the width of the deck = 28 feet

A = LxW

A = 42 feet x 28 feet

A = 1176 square feet

Remaining area to be painted = 1176 square feet – 350 square feet

Remaining area to be painted = 826 square feet

- "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."
