x = 29 - 15

x = 14

A chord consists of notes that sound good together. The C major chord starting at middle C has the following frequencies: C - 26
Bingel [31]

Answer:

The frequency of note E is:

f(E) = 330 Hz

The frequency of note C is:

f(C) = 262 Hz

The ratio of the frequency of note E to the frequency of note C is just the quotient of these two frequencies:

r  = f(E)/f(C) = 330Hz/262Hz = 330/262 = 1.26

Now, we want to find how man E waves will fit in the length of four C waves.

Note that here the word "length" is used, so we need to work with the wavelengths, not with the frequencies.

For waves, we have the relationship:

v = f*λ

where:

v = velocity (in this case, velocity of the sound = 343 m/s)

f = frequency

λ = wavelength.

So, the length of a single E wave is:

λ(E) = (343 m/s)/(330 1/s) = 1.04 m

And the length of a single C note is:

λ(C) = (343 m/s)/(262 1/s) = 1.30 m

In four C waves, the length is:

4*λ(C) = 4*1.30m = 5.2m

The number of E waves that fit in the length of four C waves is equal to the quotient between the length of four C waves and one E wave:

N = (4*λ(C))/(λ(E) ) = (5.2 m)/(1.04m) = 5.14

So we can fit 5 E waves into four C waves.

Solve the following equation algebraically show the steps: <br><br><br> n/3 -5 = 5
Lana71 [14]

\longrightarrow{\green{   \: n = 30 }} 

\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}

\frac{n}{3}  - 5 = 5

➼ \:  \frac{n}{3}  = 5 + 5

➼ \:  \frac{n}{3}  = 10

➼ \: n = 10 \times 3

➼ \: n = 30

Therefore, the value of n is 30.

\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}

\frac{30}{3}  - 5 = 5

✒ \: 10 - 5 = 5

✒ \: 5 = 5

✒ \: L.H.S.=R. H. S

Hence verified.

Show your work. -2.5(4x -4) = -6
serg [7]

Answer:

x = 1 3/5

Step-by-step explanation:

distribute.

-2.5*4x + (-2.5*-4) = -6

-10x +10 = -6

subtract 10 on both sides

-10x = -6 -10

divide by -10

x = -16/-10

x = 1 3/5
