The radioactive element​ carbon-14 has a​ half-life of 5750 years. A scientist determined that the bones from a mastodon had los
Gnesinka [82]

The bones at the time they were​ discovered when the radioactive element​ carbon-14 has a​ half-life of total 5750 years are 10062.5-year-old.

<h3>What is half-lives?</h3>

Half lives is the time interval which is need to decay the atomic nuclei of a radioactive sample.

There is a scientist who determined that the bones from a mastodon had lost 70.3​% of their​ carbon-14.  Thus, the fraction remaining is,

f=1-(70.3/100)=1-0.703

f=1-(70.3/100)=0.297

Now the fraction remaining can be given as,

f=(1/2)ⁿ

Here, n is the half life elapsed. Put the value of fraction remaining.

0.297=(1/2)ⁿ

n=1.75

The radioactive element​ carbon-14 has a​ half-life of total 5750 years. Thus,

Years=1.75*5750

Years=10062.5

Thus, the bones at the time they were​ discovered when the radioactive element​ carbon-14 has a​ half-life of total 5750 years are 10062.5-year-old.

Wrap your foot by plastic cover. B. Directions: Read the sentences carefully. Write TRUE if the statement is True and FALSE if n
luda_lava [24]

Answer:

16. false

17. True

18. True

19. True

20. false

Step-by-step explanation:

16. all terms are expressions of weather - except for cold snow. "snowfall" would be the weather condition. "snow" itself is the accumulated mass of snowflakes on the ground.

17. that is simply true. there is nothing really to explain.

18. the same as 17. that is the definition of weather.

19. yes, that is part of the explanation of the difference between weather and climate.

20. South North is NOT a direction. it kind of contradicts itself. and what is between South and North ? East and West. so, even from that perspective it is not clear.

overall, what kind of math question is that ? that is more for geography, Earth science, or meteorology or something like this.

A gym charges its members a one-time $10.00 sign-up fee, and $25 per month. The function
zvonat [6]

Answer:

7 months

Step-by-step explanation:

We can write the equation 25x+10=185 where 25 represents the cost per month, x represents the number of months, 10 represents the sign-up fee and 185 represents the total cost.

To isolate the variable, first subtract 10 from both sides of the equation.

This new equation should look like: 25x=175

The next step in isolating the variable is to divide both sides of the equation by 25.

Doing this, you should be left with the final equation x=7 which is your answer.
