If a 2-liter container of motor oil is sold for $4.50, what is the total sales amount for 2-liter containers on this particular day?

answer: idk man i can't understand you could you translate

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."

the height of the surface increases from the center out to the sides of the road

it is c!

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
