emaining in it. Carbon-14 has a half-life of approximately 5700 years. You can conclude that the age of the fossil is about __________.a. 4 × 5700 yr = 22,800 years
b. 16 × 5700 yr = 91,200 years
c. 1/16 × 5700 yr = 356 years

Answer:

The correct answer is:

5×5700 yr = 28,500 years (d)

Explanation:

The half life of an element/atom is the time is takes for that element/atom to decay to half of its original mass/size.

It was found that the carbon-14 atom had decayed until only \frac{1}{16th} of the original size is still remaining.

Now, let us first find how many half lives are in one-sixteenth, and that is \frac{1}{2}* \frac{1}{2}* \frac{1}{2}* \frac{1}{2} = \frac{1}{16}. so it means that there are 4 half lives in one-sixteenth, and since one half life takes approximately 5700 years, therefore 4 half lives will take 4×5700 yr = 22, 800 years, but at this point (22,800 years ago)the fossil has already half-life, therefore the additional age is to add the number of years it took to decay that half life. hence the age of fossil is:

22,800 + 5700 = 28, 500 years

Cruiseline offers nightly dinner cruises departing from several cities on the eastern coast of the United States including​ Char
nlexa [21]

Answer:

6,750 dinner cruise tickets

Explanation:

The computation of the break even point in units is shown below:

= (Fixed expenses + target profit) ÷ (Contribution margin per unit)  

where,  

Contribution margin per unit = Selling price per unit - Variable expense per unit  

So, the contribution margin per unit is

= $80 - $40

= $40

And, the fixed expenses is $240,000

And, the target operating income is $30,000

So, the target sales in units is

= ($240,000 + $30,000) ÷ ($40)

= 6,750 dinner cruise tickets

Respond to the following comments:
MakcuM [25]

Answer:

Comment for statement A -  The firm must still compare the IRR with the opportunity cost of capital when using the IRR rule. Therefore, even with the IRR method, the   appropriate discount rate must still be specified.

Comment for statement B - There should be a higher discount rate on risky cash flows than the rate used to discount less risky cash flows.

Making use of the payback rule is equivalent to using the NPV rule with a zero discount rate for cash flows before the payback period and an infinite discount rate for cash flows thereafter.

Explanation:

a)

“I like the IRR rule. I can use it to rank projects without having to specify a discount rate”

The firm must still compare the IRR with the opportunity cost of capital when using the IRR rule. Therefore, even with the IRR method, the   appropriate discount rate must still be specified.

b.

“I like the payback rule. As long as the minimum payback period is short, the rule makes sure that the company takes no borderline projects. That reduces risk”

There should be a higher discount rate on risky cash flows than the rate used to discount less risky cash flows.

Making use of the payback rule is equivalent to using the NPV rule with a zero discount rate for cash flows before the payback period and an infinite discount rate for cash flows thereafter.
