Answer:
3750 strings.
Step-by-step explanation:
First we have 6 different letters to choose from (a, b, c, d, e, f) and we will make a string of length 5.
First, we would have to choose one of the letters, to do this we would have 6 choices.
For our second choice, we can only choose from 5 letters since we cannot choose the one that we already chose (no two consecutive letters can be the same).
Then, for our third choice, we would have to choose from 5 different letters (any letter but the one before).
Similarly for our fourth and fifth choice, we can choose 5 different letters.
Then, the total amount of strings would be:
6 x 5 x 5 x 5 x 5 = 6 x 5⁴ = 3750 strings.

Answer:
Step-by-step explanation:
Working backward, $10,000 is 1% of $1,000,000, so that is the amount of the "remaining."
Apparently that is what is left of 1/2 the "remainder" after $50 million goes to the hospital. So 1/2 the "remainder" is $51M, which is also the amount the teacher gets. Those came out of a total of 2×$51M = $102M, which is the amount after the dog's $5M share.
The fortune was $107 million. The shares were ...
Answer:
21
Step-by-step explanation:
Let the smallest of the numbers be N
The other two numbers (consecutive) would be written as (n + 2), (n + 4)
Expressing these as an equation gives : (n) + (n+2) + (n+4) = 69
opening the bracket and collecting like terms, we have:
n+n+n+2+4=69
3n + 6 = 69
3n = 69 - 6
3n = 63
Dividing both sides by 3 or making n the subject formular, we get:
n = 63/3
n = 21.
Note, the other numbers are: 21, 23, and 25
They are all odd numbers
Their sum equals to 69
Answer:
2=53 employees(m)
4=91 employees(m)
6=129 employees(m)
8=167 employees(m)
Step-by-step explanation:
19x2=38+15= 53
19x4=76+15= 91
19x6=114+15=129
19x8=152+15=167
