Answer:
.042 ounces
Step-by-step explanation:
First, calculate how many mg you take in a day. 24/8=3, and 3*400=1200, so assuming you don't miss any, you would take 1200 milligrams in a day. You can change this to 1.2 grams. The conversion rate from grams to ounces is about .035, so you would get 1.2*.035. That makes .07*.6, which is 42 with 3 decimal points to the left. That's about .042 ounces.

b. How many cells are in the honeycomb after the ninth ring is formed?
By plugging in the ring number, 9, in the equation for the number of
cells in a ring, gives 54.
Response:
A. The rule for the number of cells in the ring is, aₙ = 6 + (n - 1) × 6
B. The number of cells in the ninth ring are 54 cells
Given;
The type of sequence = Arithmetic sequence
From the possible drawing of the question obtained from a similar question, we have;
Number of cells in thefirst ring that goes around the first cell = 6
Number of cells that go around thesecond ring = 12
A. The common difference of the arithmetic sequence = 12 - 6 = 6
We have that the nth term of an arithmetic sequence is; aₙ = a + (n - 1)·d
Taking the first ring as the first term, we have;
a = 6
Which gives;
The rule for the number of cells in the ring is, aₙ = 6 + (n - 1) × 6
Where;
n = The ring number
B. In the ninth ring, we have;
a₉ = 6 + (9 - 1) × 6 = 54

Answer:
Part B is 271!!!
Step-by-step explanation:
a9=54
S9=9/2(6+54)=270

Answer: They can visit all 5 cities in 120 different ways
Step-by-step explanation: If the family has the option of visiting five different cities in Europe, and they intend to visit all of them, then they can visit any one first and go on to another one, and so on till they exhaust all their options.
However, there is the option of which to visit first, which to visit second, and so on. This means if they decide for example, to start with Athens then they may decide to visit any of the four other cities afterwards in more than one way, and this is because all the other four cities equally have the option of being number two. So with Athens at number one, we have the other four equally likely to be number two, and so on.
To make this less cumbersome, we shall apply the formula for permutations. Rather than counting numbers of arrangements like described above, Keisha's family can use the permutation formula which is;
Pₙ = n!
Where n is the number of available options,
P₅ = 5!
P₅ = 5 x 4 x 3 x 2 x 1
P₅ = 120
Hence, the family can arrange their trip to Europe in 120 different orders
