r=AB=AC=BC, AD=r/2, ED=DF=CD=squareroot(3.r)/2

The area of square is : (EF)^2=(squareroot(3.r))^2=3r^3

The area of circle is : (pi.r^2)

The ratio will be: 3/pi

Mia hired a moving company. The company charged \$500$500dollar sign, 500 for its services, and Mia gives the movers a 16\%16%16
Tamiku [17]

Answer:

Consider the complete question is,

'Mia hired a moving company. The company charged $500 dollar sign, 500 for its services, and Mia gives the movers a 16%, percent tip. How much does Mia tip the movers?'

Reference : brainly.com/question/11225910

Solution :

The original amount charged = $ 500,

Percentage of tip = 16%,

Thus, the amount of tip = 16% of the original charge

= 16% of 500

=\frac{16\times 500}{100}

=\frac{8000}{100}

= $ 80

Hence, Mia gave $ 80 tip to the movers.

A sodium Isotope has a half life of 15 hours how much sodium is left after 100 hours
JulsSmile [24]
We'll say beginning amount is 100
Ending Amount = Beginning Amount / 2^n  where n is the number of half-lives
100 hours mean six and 2/3 half-lives will elapse
Ending Amount = 100/2^(6.666666)
Ending Amount = 100 / <span> <span> <span> 101.59
</span></span></span>Ending Amount = <span> <span> <span> 0.9843488532 </span> </span> </span>
So if we started with 100 grams after 100 hours (or 6.6666666 half-lives) we would only have <span> <span> 0.9843488532 </span> grams remaining.
