Four numbers for my set 0 to 9 including 0 9 are used to create a personal identification number once a numbers use it cannot be reused how many possible outcomes begin with a 0

504

Step-by-step explanation:

Given : The number of digits used to make the personal identification number  =10

The total digits in the personal identification number =4

If repetition of digits is not allowed then the number of possible outcomes is given by permutations .

The number of possible outcomes begin with a 0 is given by [ first place is fixed for 0, so we take 1 for it then apply permutation on the rest of 9 digits taking 3 at a time]:-

Hence, the possible number of outcomes =504

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
