After reviewing the graph you have given with the question, there are several reasons why carbon 14 can't be used to accurately determine the age of organic remains that are 1 million years old.

A few of the reasons are; Carbon-14 has a short half life, after 1,000,000 years there wouldn't be enough carbon 14, and too little of the original radioactive sample would remain. Any of these choices are correct for the answer to the question you asked.

If the average sale price of lignite coal is $19.51 per 2,000 lbs, a geology log has 3 layers of coal which add up to 3.65 meter

fredd [130]

Answer:

price = $48433333.5

Explanation:

given data

average sale price = $19.51 per 2000 lbs

layer of coal = 3

add = 3.65 meter thickness

area = 478218 square meter

to find out

What is the economic evaluation

solution

we find first volume that is

volume = area × thickness

volume = 478,218 × 3.65

volume = 1745495.7 m³

and we know density that is 1290 kg/m³

so weight = volume × density

weight = 1745495.7 × 1290

weight = 2251689453 kg × 2.205 lbs

weight = 4964975244 lbs

so price for 4964975244 lbs is

price = $\frac{19.51}{2000}$ × 4964975244

price = $48433333.5
