Diagonal cuts are used to a. shorten cooking time. b. peel vegetables. c. square off vegetables. d. add home-style appeal.

answer; i believe the correct answer is "he who gladly serves"

including the octave, the answer would 8 notes in a major scale with one note being played twice. ex) c major scale includes: c, d, e, f, g, a, b, c

notice that c is played twice

however, if you were to ask me how many different notes are in a major scale- the answer would be 7.
