Final answer:
Sentences 1, 2, 3, and 5 are in active voice because the subjects (the dog, the kids, Mike, and the girl) are performing the actions. Sentences 4 and 6 are in passive voice because the subjects (the dishes and Dad's car) are having something done to them.
Step-by-step explanation:
When determining whether a sentence is in active voice or passive voice, you need to look at whether the subject is performing the action or receiving it. A sentence in the active voice will have the subject doing something, whereas the passive voice will have the subject having something done to it, often accompanied by a form of the verb 'to be' and possibly a 'by' phrase indicating who or what is acting.
