Hi got a question!
A Rectangular container holds 10 litres of water when full. Its height is 10 cm. What is its base area?
be quick th

5cm

Explanation:

5 times 10 is 50 if you make squared you add two zeros to get 5 thousand and that showcases what liters from ten would be inside.

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.  

the answer is counterpoint.

counterpoint definition: "the art or technique of playing a melody or melodies in conjunction with another, according to fixed rules."

counterpoint is present in a lot of baroque music- such as bach (notably his wtc prelude and fugues) and scarlatti, but can also be found in music by mozart, beethoven. it can even be found in music as modern as john williams!
