A chord consists of notes that sound good together. The C major chord starting at middle C has the following frequencies: C - 262 Hz E - 330 Hz G - 392 Hz determine the ratio of the frequency of E to C. Express the answer in a simple integer ratio. How many E waves will fit in the length of four C waves. a. 2 b. 3
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.
Answer:
The ratio of the frequency of E to C can be found by dividing the frequency of E by the frequency of C:
330 Hz / 262 Hz ≈ 1.26
To express the answer in a simple integer ratio, we can divide both 330 Hz and 262 Hz by their greatest common factor, which is 2:
330 Hz / 2 = 165 Hz
262 Hz / 2 = 131 Hz
So the ratio of the frequency of E to C is:
165 Hz / 131 Hz = 15/12 ≈ 1.25
This ratio is approximately equal to 5/4
Therefore, the answer is (A) 5 to 4
How do you write four less than seven?
A.7 + 4
B.7 - 4
C.7 x 4
D.7/4
Answer:
B.
Step-by-step explanation:
D mean 7 divided by 4
A is 7 plus 4
C is 7 multiplied by 4
B is 7 minus 4 (4 less than seven expression)
Answer:
B
Step-by-step explanation:
Four less than 7 means that the answer should be 4 smaller than 7.
So it could be though of 7-4=3
The first part 7-4, looks like asnwer B.

in me franklins algebra course, eight students recently took a test their grades were as followed: 35, 77, 80, 86, 87, 90, 94, 100
calculate the mean and median of this data set
Answer:
Mean= sum/no.
= 35+77+80+86+87+90+94+100 / 8
= 649/8
=81.125 was the mean
Median: the middle number
35, 77, 80, 86, 87, 90, 94, 100
Both are in the middle so: 86+87/2
=173/2
=86.5 as the median

What is the range of the years?
Answer:
6
Step-by-step explanation:
The range of a data set is the numbers covered by the data. This means that the range is the difference between the minimum and maximum. The minimum is the smallest point, 2, and the maximum is the largest point, 8. Therefore, since 8-2=6, 6 must be the range.

Answer:
A) <SQT = 36 degrees
B) <QRW = 36 degrees
C)<PRV = 72 degrees
Step-by-step explanation:
A) <SQT = 36 degrees (< SQT and < PQR are vertically opposite angles, and vertically opposite angles are equal)
B) <QRW = 36 degrees ( <QRW and < SQT are corresponding angles since they lie on the same side of the transversal across the parallel lines. Corresponding angles are equal)
C)<PRV = 72 degrees( <PRV is the exterior base angle to < PQR and exterior base angles, are always twice their interior correxpondents)

At a local seaside, a vendor sells single-cone ice-creams for $3 and double-cone ice-creams for $4.50. The vendor stocks a maximum of 70 single cones and a maximum of 45 double cones. For the afternoon he expects to sell no more than 50 ice-creams.
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of single cone ice cream and let y represent the number of double cone ice cream.
Since the vendor stocks a maximum of 70 single cones and a maximum of 45 double cones. hence:
0 < x ≤ 70, 0 < y ≤ 45 (1)
The vendor expects to sell no more than 50 ice creams, hence:
x + y ≤ 50
Plotting the constraint using geogebra online graphing tool, we can see that the solution to the problem is at (5, 45)
Since the vendor sells single-cone ice-creams for $3 and double-cone ice-creams for $4.50, hence:
Revenue = 3x + 4.5y
At the point (5, 45), the revenue is:
Revenue = 3(5) + 4.5(45) = $217.5
Find the equation of the line that is parallel to the line y = 2x - 5 and passes through the point (-1,3).
Answer:
y=2x+5
Step-by-step explanation:
If you graph it you can figure out the starting point of the parallel line.
The rate of change is 2 and since the point the parallel line needs to pass through is (-1,3) you need to shift the starting point (y-intercept) up by 10 units.
Shifting the y-intercept of y=2x-5 up by 10 makes the new line y=2x+5.

Answer:
20π cubic units
Step-by-step explanation:
The volume of a cylinder is the area of the base x height.
The area of a circle is π r^2 squared.
So the area of the base is π ⋅ 2^2 = 4π
The height of the cylinder is 5, so the volume is 4π ⋅ 5 = 20π cubic units

Angle A is circumscribed about circle O.
What is the measure of angle O?
[picture below]
Answer:
134°
Step-by-step explanation:
[tex] In\: \odot O,[/tex] AB and AC are tangents at points B and C respectively. OB and OC are radii.
[tex] \therefore OB\perp AB\: \&\: OC\perp AC[/tex]
(By tangent radius theorem)
[tex] \therefore m\angle ABO =m\angle ACO = 90\degree [/tex]
[tex] m\angle CAB+ m\angle ABO +m\angle ACO+ m\angle BOC = 360\degree [/tex]
[tex]\therefore 46\degree + 90\degree +90\degree+ m\angle BOC = 360\degree [/tex]
[tex]\therefore 226\degree + m\angle BOC = 360\degree [/tex]
[tex]\therefore m\angle BOC = 360\degree-226\degree [/tex]
[tex]\therefore m\angle BOC = 134\degree [/tex]
[tex]\implies m\angle O= 134\degree [/tex]
