Please Help Me! It’s Math! Please!
nadezda [96]

Answer:

D. About 800 years

Step-by-step explanation:

Use the half-life equation:

A = A₀ (½)ⁿ

where A is the final amount,

A₀ is the initial amount,

and n is the number of half-lives.

0.90A₀ = A₀ (½)ⁿ

0.90 = (½)ⁿ

To solve for n, take log of both sides:

log 0.9 = n log 0.5

n = (log 0.9) / (log 0.5)

n = 0.152

It takes 0.152 half-lives.  The half-life of carbon-14 is 5730 years.

0.152 × 5730 years = 871 years

The closest answer is D.

A square pyramid is shown below:
madreJ [45]
Let Surface Area A, a the base edge and h the height:

A = a²+2a√(a²/4+h²)

h=?

pythagorean theorem:

h²=c²-a²

h=√(c²-a²)

h=√(8²-(.7/2)²)= 8

plug it in the above equation A= 11.7ft²

So A is correct
