Answer:
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 <em>ratio of both values multiplied by 100. </em>
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.

Answer:
50 million
Step-by-step explanation:
You don't need to go to the trouble to find the value of k in e^(kt). Rather, you can use the given ratio directly.
When t = years after 1990, the population of 49 million took 12 years to achieve. The estimate desired is for 16 years after the year 1990. The appropriate exponential formula for the population is ...
P = 46·(49/46)^(t/12)
Then for t=16, this is ...
P = 46·(49/46)^(16/12) ≈ 50.04 . . . . million
The population in 2006 is estimated at 50 million.
_____
The form of the exponential equation we used above is ...
f(x) = (baseline value)·(ratio to baseline)^(x/(interval corresponding to ratio))

Answer:
The cost for 1 necklace is $3.
Step-by-step explanation:
With the information provided, you can say that the amount spent in bracelets and necklaces is equal to the price per bracelet for the number of bracelets plus the price per necklace for the number of necklaces, which is:
c=3x+2y, where:
c is the total cost
x is the price per bracelet
y is the price per necklace
Now, you can say that c=21 and x=5 and solve for y to find the price per necklace:
21=(3*5)+2y
21=15+2y
21-15=2y
6=2y
y=6/2
y=3
According to this, the answer is that the cost for 1 necklace is $3.
