Mr. Hawkins is covering a room in carpet. The room measures 14 feet by 12 feet in a rectangular shape. Each square foot of carpet costs $2.10. What is the cost of carpeting the room?

Cost of carpeting the room will be $ 352.8

Step-by-step explanation:

Given,

The geometrical shape of the room is rectangular.

Length of the room = 14 feet

Breadth of the room = 12 feet

Area of the rectangular room = length of the room × breadth of the room

⇒ 14 feet × 12 feet

⇒ 168 square feet

Cost of carpeting one square foot = $ 2.10

∴ Cost of carpeting the room = Cost of carpeting one square foot × Area of the room

⇒ $ 2.10 × 168 square feet

⇒ $ 352.8

- "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."

your answer   is c
