An artifact was found and tested for its carbon-14 content. If 72% of the original carbon-14 was still present, what is its prob
Artyom0805 [142]

Answer:

  2700 years

Step-by-step explanation:

The exponential function for the fraction remaining is ...

  r(t) = (1/2)^(t/5730)

where r is the remaining fraction and t is the time in years. We can solve for t to get ...

  log(r) = (t/5730)log(1/2)

  t = 5730·log(r)/log(1/2)

For the given r=0.72, the age of the artifact is estimated to be ...

  t = 5730·log(0.72)/log(0.5) ≈ 2700 . . . years

If a bored game was originally $25 and it is on sale for $18 , what is the percent discount?
Blizzard [7]
Hi there!

To find the percent discount, we need to divide the new price by the original price without the discount:

18 / 25 = 0.72

Now, we convert this into a percentage, so we can find the <em>percent </em>discount:

0.72 = 72%

Now, we subtract from 100%:

100% - 72% = 28%

So, the answer is 28%. 

Hope this helps!

Cody has $7. He wants to
Temka [501]
<h3>Answer:    (1,3)</h3>

=====================================================

Explanation:

Note that the two shaded regions overlap to form the darker shaded region. The point (1,1) is only in the green region, but not in the blue region. It needs to be in both regions for it to be a solution to the system. In contrast, the point (1,3) is on the boundary of the blue region and in the green region as well. It's a solution point because of this.

Points on the boundary are included because of the "or equal to" as part of the inequality sign. Hence the solid boundary lines rather than dashed boundary lines.

The solution (1,3) means that x = 1 and y = 3 pair up together. It says that Cody can buy x = 1 hotdog and y = 3 packs of peanuts so that he has at least 4 snacks, and he stays within the $7 budget.

Going back to (x,y) = (1,1) for a moment, this isn't a solution because x+y = 1+1 = 2 is not 4 or larger. In other words, he only buys 2 snacks here instead of 4 or more.
