Answer:
3rd table, 2nd table, 1st table
Step-by-step explanation:
So, the table ratios for the first at 5:10 and 6:12. Which can be simplified to 1:2, meaning 1 quart for every 2 pints.
The second table's ratios are 2:16 and 3:24. Which also can be simplified to 1:8, meaning 1 cup for every 8 fluid ounces.
The last table's ratios are 8:56 and 10:70. Which as well could be simplified to 1:7, meaning 1 week for every 7 days.
Hope this helps :)

Using proportions, it is found that the number of books that was left over was of 505.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The number of books received by Marie is given by:
M = 772 - 345 = 427.
Melanie received one-sixth of Marie, hence:
Me = 427/6 = 71.
The total amount is 25 times Melanie's amount, hence:
T = 25 x 71 = 1775.
The amount left over is:
L = 1775 - (772 + 427 + 71) = 505

Answer: Pupulation = A*0.95^t
where t is the numer of hours that has passed, and A is the initial population of the bacteria.
Step-by-step explanation:
If the initial population of bacteria is A.
After one hour we can see that the population has decreaesed by 5%, so the new population is
P = A - 0.5*A = 0.95*A
After other our, the population decreased by 5% again, the new population is:
P = (0.95*A) - 0.5*(0.95*A) = 0.95*0.95*A = A*0.95^2
And so on.
This is an exponential decay, so we can write this relation as:
Pupulation = A*0.95^t
where t is the numer of hours that has passed, and A is the initial population of the bacteria.
