Final answer:
The name of the musical note represented by a dotted quaver followed by a semiquaver is crotchet.
Step-by-step explanation:
The name of the musical note represented by a dotted quaver followed by a semiquaver is a crotchet. A crotchet is a note that is half the duration of a minim and twice the duration of a quaver. In musical notation, a crotchet is represented by a filled-in oval-shaped notehead with a stem. When a dot is added to a note, it increases its duration by half.
