in this problem we have
substitute in the formula above
----> equation that represent the balance in the account after 2 years
Answer:
Number of of pieces are 45 .
Step-by-step explanation:
Let us assume that the number of pieces be x .
As given
The length of the rope is 10m and pieces are cut from it .
Than the equation becomes
9 × 5 = x
45 = x
Therefore the number of of pieces are 45 .
N = 4
(3)(4)-(2+4) = 12 - 6 = 6

==================================================
Explanation:
If we could tell the repeated letters apart, then there would be
11*10*9*8*7*6*5*4*3*2*1 = 39,916,800
different ways to scramble up the letters.
However, we have 2 copies of b and 2 copies of i
So we have to divide by 2*2 = 4 to correct this overcounting
(39,916,800)/4 = 9,979,200
