Most intruments produce notes across ranges called octaves which are made up of 8 notes how many octaves do 51 notes span?
mojhsa [17]

Answer: 51 notes span 6 octaves.

Step-by-step explanation:

The word "octave" is a Latin word that means "eight".

In an instrument, Each octave is made up of 8 musical notes.

If we have 51 notes , the number of octaves can be made in it = \dfrac{51}{8}

=6.375\approx6\ \ \ \ \ \text{[Rounded to the nearest whole number]}

Hence, 51 notes span 6 octaves.

For questions 1-3, decide for each graph whether the equation shown is a function. Label each graph
ruslelena [56]

Answer:  Not a function

<u>Step-by-step explanation:</u>

The graph fails the vertical line test.  In other words, when you draw a vertical line anywhere through the curve, the line passes through two points.

Bonus: If you do not have a graph, it is not a function if there is one x-value that has two different y-values.

For example, If (1, 2) and (1, -2) lie on the curve, then it is NOT a function because the x-value (1) has two different y-values (2 & -2).

Can y’all plz help me
Verdich [7]

Answer:

D. 10

Step-by-step explanation:

Assuming that <COA is a right angle, we can say that the two given angles are complementary

complementary angles are angles that add up to 90 degrees

this means we can create this equation: 3x + 46 + 14 = 90

so subtract 46 and 14 from 90: 3x = 30

divide both sides by 3: x = 10
