If anwr (the arctic national wildlife refuge) yields a projected peak amount of approximately 330 million gallons of oil per year and the united states uses roughly 110 billion gallons of oil per year, what percent of the oil used per year in the united states would anwr provide?

ANWR would provide 0.3% of the oil used per year in the United States.

Step-by-step explanation:  

We need to know that the ANWR "yields a projected peak amount of approximately 330 million gallons of oil per year", and the United States uses roughly 110 billion gallons of oil per year.

We also need to remember that a million and a billion can be expressed respectively as follows:

So, we can mathematically describe all this as:

Thus, the "percent of the oil used per year in the United States" that ANWR would provide, is the ratio of both values multiplied by 100.

Then

Then, the percent of the oil used per year in the United States that ANWR would provide is only 0.3% of the annual demand for United States.

- "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."
