70% decay means 30% remains
.3 = (1/2)^(t/3.3)
take the log of both sides
log.3 = t/3.3 * log1/2
Divide both sides by log 1/2
log.3 / log1/2 = t/3.3
use calculator
1.736965594166206 = t/3.3

t = 5.73 hours
Answer:
20% of the Congress is made of Senators.
Step-by-step explanation:
Our whole here is 500, since the House of Representatives and Senate combined would have 500 members in this case. So, we now need to find out how many senators there are.
x
=
Now, since we know the fact that there are 100 senators in Congress, we will find out what percent of 500 is 100.
100 = 20% of 500. To check, we will multiply 5 by 100. We get 500.
Therefore, the answer is 20%.
