Irrational number between 9.5 and 9.7...
9.678937... (never ending)...it is irrational because it cannot be made into a fraction because it is infinite.
the decimal approximation to the nearest hundredth is : 9.68
B, the bottom of the figure contains points E, F, and H
The answer should be Two and Three ...

Step-by-step explanation:
If 6 planters= $18 then 16 planters= 16x 18 divided by 6 =$48
Answer:
From what I can see of the problem, you CANNOT solve for the half-life of U 235 AND then solve for the length of time to determine the 20% decay.
U-235 half-life is 704,000,000 years. (Wikipedia)
The elapsed time formula = half-life * [log (Beginning Amount / ending amount) / log 2]
elapsed time = 7.04 x 10^8 * [log (100 % / 80%) / log 2]
elapsed time =7.04 x 10^8 * [log (1.25) / .30103]
elapsed time =7.04 x 10^8 * [0.096910 / .30103]
elapsed time = 7.04 x 10^8 * 0.321928047
elapsed time = 226,637,000 years
