Help, i've been trying for around 30mins and I can't figure it out.
omeli [17]

Answer:

<h2><em><u>Option</u></em><em><u> </u></em><em><u>A</u></em><em><u> </u></em><em><u>and</u></em><em><u> </u></em><em><u>C</u></em></h2>

Step-by-step explanation:

As,

2 \sqrt{75}  + 3 \sqrt{50}

= 2 \sqrt{25 \times 3}  + 3 \sqrt{25 \times 2} (A)

= 2 \times 5 \sqrt{3}  + 3 \times 5 \sqrt{2}

= 10 \sqrt{3}  + 15 \sqrt{2} (C)

Find the median if this set of numbers: 7, 6, 19, 12, 16, 19, 19, 6 ​
tankabanditka [31]

Answer:

20

Step-by-step explanation:

Order the numbers from smallest to largest, then cross one number off until you have one or two numbers left.

If there is an EVEN number of numbers(like this one): there will be two numbers left, therefore you add those two numbers together, then divide by two.

If there is  an ODD number of numbers: there will be one number left, therefore that is your answer!

Hope this helps!

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.
