Which tense does the sentence below use?All of the cupcakes have been eaten by Stephen Curry and me.

The sentence "All of the cupcakes have been eaten by Stephen Curry and me." uses the present perfect passive tense.

Here's the breakdown:

1. "Have been eaten" is a verb phrase in the present perfect tense. In the present perfect, the action is completed relating to now. "Have been" is the auxiliary verb showing present perfect tense.

2. The main verb "eaten" is in past participle form, which is typical in present perfect tense.

3. The sentence is in passive voice because the subject of the sentence (the cupcakes) is the recipient of the action, not the doer. The doer of the action (Stephen Curry and me) comes after the verb, which is a characteristic of the passive voice.
