It is a very simple answer but it works!
Answer: 48.97
Step-by-step explanation:
Answer: it will take them about 24 minutes working together
Step-by-step explanation:
1/40 + 1/60 =
6/240 + 4/240 = 10/240 = 1/24
1/24 = 1/t
Cross multiplication:
1*t = 1*24
t= 24
17.97 + 25.49 + 3x = 50.33
17.97 + 25.49 + 3x - 17.97 - 25.49 = 50.33 - 17.97 - 25.49
3x = 6.87
3x/3 = 6.87/3
x = 2.29 per pair of socks
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.
