Explanation:

The exercise aims for you to practice the Future Perfect by conjugating the appropriate verb in each sentence.

The future perfect tense is used to describe what will have happened in the future before a different action takes place, or by a specific time.

Like perfect tenses, the future perfect is formed by using the auxiliary verb HABER with the past participle. In this case, HABER is conjugated in the future tense because of the future perfect.

yo habré

tú habrás

él/ella habrá

nosotros habremos

vosotros habréis

ellos/ellas habrán

Here is the translation of the complete sentences:

1. By Tuesday, Armando will have already sent the invitations by email.
