The missing frequencies for G# and D# in the given equal temperament octave is 311.1 and 415.3 respectively. The ratios of frequencies between G# and D# is 1.33.
What is an equal temperament octave?The equal tempered scale is the common musical scale used at present, used for the tuning of pianos and other instruments of relatively fixed scale. It divides the octave into 12 equal semitones. The ratio between successive notes is constant and it is 1.0595.
With reference to the image attached in the question,
Since we know that ratio between successive notes is 1.0595.
This implies,
[tex]\frac{C\#}{C} = \frac{277.2}{261.6} = 1.0595\\\\[/tex]
Or we can say that, C# = 1.0595C
Similarly,
D# = 1.0595D = 1.0595 * 293.6 = 311.1
G# = 1.0595G = 1.0595 * 392 = 415.3
The ratios of frequencies between G# and D# = [tex]\frac{G\#}{D\#} = \frac{415.3}{311.1} = 1.33 = \frac{4}{3}[/tex]

Juan went to the store to buy a plant for his mother, but forgot to ask which kind to get. Out of 30 plants, eighteen of them are a kind that his mother would want. If Juan chooses one randomly, what is the probability that he will choose a kind that his mother would want?
Answer:
Probability [Randomly choose plant Juan's mother want] = 3 / 5
Step-by-step explanation:
Given:
Total number of plant in store = 30 plants
Number of plant kind Juan's mother want = 18
Find:
Probability [Randomly choose plant Juan's mother want]
Computation:
Probability of an event = Number of favorable outcome / Total number of outcomes
Probability [Randomly choose plant Juan's mother want] = Number of plant kind Juan's mother want / Total number of plant in store
Probability [Randomly choose plant Juan's mother want] = 18 / 30
Probability [Randomly choose plant Juan's mother want] = 3 / 5

The circumference of a circle is 9π m. What is the area, in square meters? Express your answer in terms of π
Answer:
[tex]20.25\pi\:\mathrm{m^2}[/tex]
Step-by-step explanation:
Formulas to know:
Area of a circle: [tex]A=r^2\pi[/tex]Circumference of a circle: [tex]C=2r\pi[/tex]Since we know the circumference, we can use formula for the circumference of a circle to find the circle's radius:
[tex]9\pi=2r\pi,\\9=2r,\\r=4.5[/tex]
Now we can plug in [tex]r=4.5[/tex] into the formula for an area of a circle:
[tex]A=4.5^2\pi=\boxed{20.25\pi\:\mathrm{m^2}}[/tex]
Answer:
20.25 pi
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
9 pi = 2 * pi *r
Divide each side by 2pi
9pi / 2 pi = 2 pi r / 2 pi
4.5 = r
Now we can find area
A = pi r^2
= pi ( 4.5)^2
20.25 pi

Find the value of r.
Answer:
r = 10.5
Step-by-step explanation:
using the Pythagorean theorem:
(7 + r)² = 14² + r²
49 + 14r + r² = 196 + r²
subtract r² from both sides of the equation:
14r + 49 = 196
subtract 49 from both sides:
14r = 147
divide both sides by 14:
r = 10.5

Step-by-step explanation:
The equation of a parabola is y=x^2–4x+13. Write the equation in vertex form.
Simplify any fractions.
Answer:
y = (x - 2)² + 9
Step-by-step explanation:
To obtain the equation in vertex form use the method of completing the square.
Add/ subtract ( half the coefficient of the x- term)² to x² - 4x
y = x² + 2(- 2)x + 4 - 4 + 13
= (x - 2)² + 9 ← in vertex form
Answer:
vertex form : y=(x-2)^2+9
Step-by-step explanation:
To convert a parabola from standard form y=x^2-4x+13 to vertex form, we complete the square.
first, complete the square using the x-terms, use the constant term to adjust and make a perfect square.
y= x^2-4x+4 + 9
Factor the first three terms on the right-hand side.
y=(x-2)^2 + 9
the resulting express is then the vertex form, which means that
the vertex is at (x-2) = 0, x=2, and at y=9.

Thomas paid $4.25 for three apples and four oranges. Five apples and two oranges cost Casey $4.75. Let x represent the number of apples and y represent the number of oranges. Which system of equations represents this situation? A $~3x+4y=4.75~$ $~5x+2y=4.25~$ B 3x+4y=4.25 5x+2y=4.75 C 4x+3y=4.75 2x+5y=4.25 D 4x+3y=4.25 2x+5y=4.75
Answer:
B
Step-by-step explanation:
For the given situation, system of equations is represented by
3x + 4y = 4.25
5x + 2y = 4.75
What is system of equations?"A system of equations is a finite set of equations for which we find the common solution."

Situation 1 : Thomas paid $4.25 for the three apples and four oranges , which can be represented by equation:
3x + 4y = 4.25
Situation 2: Casey paid $4.75 for five apples and two oranges, which can be represented by equation:
5x + 2y = 4.75
Hence we can conclude that Option B is correct.

What value of x makes the 2 triangles congruent by HL? Find the length of CB
Step-by-step explanation:
here's your solution
==> Both traingle are congruent
==> BC = BD. [ c.p.c.t ]
==> x + 8 = 3x - 14
==> x - 3x = - 14 - 8
==> - 2x = - 22
==> x = 22/2
==> x = 11
now CB = x + 8 = 11 + 8
CB = 19

Is it linear , quadratic, exponential
Answer:
Exponential
Step-by-step explanation:
So lets look at the table.
When x = 1, y = 3
When x = 2, y = 9.
Hmmm, this doenst seem like x+number=y. It doesnt seem like a quadratic, where the values go up, then down, then up again. Or vise versa.
So this rules out linear and quadratic, for the x doesnt change by a constant, or change the direction of y.
This leaves exponential or none of the above.
When x = 3, y = 27
When x = 4, y = 81
This seems like a exponent, since:
3 to the first power is 3
3 to the second power is 9
3 to the third power is 27
and 3 to the fourth power is 81
Answer:
exponential function
