Answer:

95

Step-by-step explanation:

1. First, the binary to decimal formula is:  

  • decimal = [tex]d_0*2^0 + d_1 *2^1 + d+2*2^2+..[/tex]  

2. Now, let's apply it:

  • [tex](1011111 )_2= (1 *2^6) + (0 *2^5) + (1*2^4) + (1*2^3) + (1 *2^2) + (1 *2^1) + (1*2^0)[/tex]
  • [tex]1(64) + 0(32) + 1(16)+1(8)+1(4)+1(2)+1(1)[/tex]
  • [tex]64 + 0 + 16 + 8 + 4 + 2 + 1[/tex]
  • [tex]80 + 8 + 4 + 2 + 1[/tex]
  • [tex]88 + 4 + 2 + 1[/tex]
  • [tex]92 + 2 + 1[/tex]
  • [tex]94 + 1[/tex]
  • [tex]95[/tex]

Therefore, the answer is 95.
