As far as I remember, we learned a lot about ratios and fractions, such as adding, subtracting, multiplying, and dividing them, as well as finding LCM and GCF.
We can calculate the age by using the formula: final amount=initial amount*(1/2)^(time/half-life), or t=ln(final amount/initial amount)/(-0.693)*half-life. The half life of C-14 is 5730 years, and final amount=initial amount is 51% or 0.51, so t=ln(0.51)/(-0.693)*5730=5567 years approximately.
Live Fund receive 
it they sold half thier holding in Marks Brothers.
<u>Solution:</u>
Given: Sale price of Live Fund holding is 5000 dollar
To find: Amount that Live Fund will get if they sell half of their holding in Marks Brothers.
Assume the total holdings held by Live Fund in Marks Brothers as N
Therfore, half the number of shares or (half the holdings) of Live Fund will be 
.
Thus, if each share is valued at 
, then the total value of the number of shares sold will be as follows,
Hence, Live Fund will receive 
If s represents the number of songs Kim downloads, her expenses for a month must satisfy the inequality
5.00 + 0.58·s ≤ 13.00
To solve this, subtract 5.00 to get the s-term by itself, then divide by the coefficient of s.
0.58·s ≤ 8.00
s ≤ 8.00/0.58 ≈ 13.79
The number of songs must be an integer, so we conclude Kim can download 13 songs, but not 14 songs.
Kim can download 13 songs without exceeding her budget.
The area of a rectangle is calculated as length times its width. So, for the given area above, the expression should b written as:
20 = LW
To know the length for various measurement of the width, we can write it by:
L = 20 / W
You can substitute any measurement to W and you can obtain the corresponding value of the length.
