The mass of the radioactive sample at the beginning of the 8th day of the experiment a_13=310.7.
In a lab experiment, the decay of a radioactive isotope is being observed.
At the beginning of the first day of the experiment, the mass of the substance was 1300 grams and the mass decreased by 6% per day.
What is the formula of the nth term?
[tex]a_n=a_1r^{n-1}[/tex]
Use the given value in the formula so we get,
[tex]a_{13}=1100(0.9)^{13-1}[/tex]
Simplify the given term
[tex]a_{13}=310.7[/tex]
Therefore, The mass of the radioactive sample at the beginning of the 8th day of the experiment a_13=310.7.

Ms. Benson can pay $293.22 for her gym membership upfront, or she can pay the amount over a period of six months. How much would Ms. Benson pay each month for the sixth month period?
Answer:
She would have to pay $48.87 a month for six months.
Step-by-step explanation:
293.22 ÷ 6 = 48.87
Answer:
$48.87
Step-by-step explanation:
For example, if it was a backruptcy we would need to get the principal amount using the simple interest formula.
Interest = Principal * interest rate * term
180 = P * 2% * 1
180 / 2% = P
9,000 = Principal
Benson pays an additional interest of 9,000 each year. Monthly payment of 750.
9,000 / 12 months = 750 per month.
But since we are just dividing the answer will be 293.22 ÷ 6 = 48.87

Terry has 3 pairs of pants (black, khaki, and brown) and 4 shirts (yellow, red, blue, and white). He does not care which colors he wears together. How many different outfits can Terry make
Answer: 12 different outfits
===========================================================
Explanation:
We simply multiply the values given to us. Think of a table that has 3 rows and 4 columns. The rows represent the different colors of pants Terry can wear. Each column is a different color shirt. Since we have 3 rows and 4 columns, we have 3*4 = 12 cells inside the table. Each cell represents a combination of pants and shirt colors. This means there are 12 different outfits possible.
Answer:
12
Step-by-step explanation:
if he has 3 pairs of pants and doesn't care what colors he wears then each shirt can go with the pants once and since there a 4 shirts and three pants then 3 times 4 =12
There were 6 marbles in a bag for read into were blue what is the probability that you will pull out a blue marble
Question: There were 6 marbles in a bag four were red two were blue what is the probability that you will pull out a blue marble
Answer:
Pr(blue) = 1/3
Step-by-step explanation:
From the question,
Probability = Possible outcome/Total outcome
Pr(blue) = number of blue marbles(B)/Total number of marbles
Pr(blue) = B/N.................... Equation 1
Where B = Total number of blue marbles, n = Total number of marbles
Given: B = 2, n = 6
Substitute these values into equation 1
Pr(blue) = 2/6
Pr(blue) = 1/3.
Hence the probability that a blue marble will be pulled out is 1/3
