Each digit can be 0-9 ( 10 numbers)
there are 9 numbers in a social security number
multiply 10 nine times:
10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 1,000,000,000 ( 1 billion) possibilities.
the restriction is it can't be all zeros so subtract 1 from the total
1,000,000,000 - 1 = 999,999,999 combinations
Answer:
she can eat 0.4 hot dogs per minute
Answer:
Step-by-step explanation:
Each new term is the sum of the two preceding terms. Given 2, 9, etc., we see that a number between 2 and 9 is missing; call it x. Then 2 + x must equal 9, and so x = 7, and so the first three terms are 2, 7, 9. Repeating the process, we add 7 and 9, obtaining 16; thus the first four terms are 2, 7, 9, 16. Continuing this pattern, we add 9 and 16 to obtain the fifth term, which is 25: 2, 7, 9, 16, 25. And so on.
The answer is c because it tells u the answer in the question kinda
The solution to the system of inequality expression is 1 < x < 10
Inequality expressions are expressions not separated by an equal sign
Given the inequality expressions
- 4x – 2 < -6 and - 4x – 2 > -42
For the inequality - 4x – 2 < -6
- 4x – 2 + 2 < -6 + 2
-4x < -4
x > 1
For the inequality - 4x – 2 > -42
- 4x – 2 + 2> -42 +2
-4x > -40
x < 10
Combining both inequality solutions:
1 < x < 10
Hence the solution to the system of inequality expression is 1 < x < 10
