A combination lock uses a 3-digit code. Each digit can be any one of the ten available integers 0_ 9 How many different combinations are possible?

729

Step-by-step explanation:

If you multiply 9x9x9 which is for the largest number and the 3 digits you would get 729.

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
