Answer:
The frequency of the note a perfect fifth below C4 is;
B- 174.42 Hz
Step-by-step explanation:
Here we note that to get the "perfect fifth" of a musical note we have to play a not that is either 1.5 above or 1.5 below the note to which we reference. Therefore to get the frequency of the note a perfect fifth below C4 which is about 261.63 Hz, we have
1.5 × Frequency of note Y = Frequency of C4
1.5 × Y = 261.63
Therefore, Y = 261.63/1.5 = 174.42 Hz.
Answer:
Step-by-step explanation:
times the number so 18 times 30
Answer: 3
Explanation:
27 = 3^3
42 = 2 x 3 x 7
So the HCF of (27,42) = 3
The sum of any two rational numbers is a rational number, so it's true.
