Answer:
Y=18x
Step-by-step explanation:
You have to add 6x plus 5 and you get 11x then you have to subtract 2x from that 11x to get 9x then you have to add 4 plus 5 and you get 9 and add 9x +9 and you get 18x. So Y=18x

Answer:
A. 60°
Step-by-step explanation:
There's a very straight-forward explanation for this, thank god! XD
For this type of problem, there's a rule to follow for the outside angle. X and 120 should equal 180, so all you need to do is fill that gap.
180-120 = 60
60 is your answer because it completes the whole angle.
what is the equation of the line?
Answer:
x=3
Step-by-step explanation:
try different values on the line! plug them in and you'll see that every x value is 3!
Answer:
x=3
Step-by-step explanation:
Because there is no slope (or the slope is undefined), there is another way to write the equation. Instead of y=mx+b, it will be either x=b or y=b, y=b being a horizontal line and x=b being vertical. To find b, simply find the value of x or y. The line has infinite points on it with one similarity, being their x value is 3. Hence, the equation is x=3.

a sound wave has a frequency of 627 hz and a wavelength of 3.25 m. what is the speed of the wave?
Answer:
2037.75m/s
Step-by-step explanation:
To calculate the speed of a wave, you need to multiply the wavelength by the frequency. In this case, 627*3.25=2037.75m/s. Hope this helps!
The speed of a sound wave with a frequency of 627 hz and a wavelength of 3.25 m is calculated using the formula v = f λ, where v is the speed, f is the frequency, and λ is the wavelength. Multiplying the given frequency and wavelength gives a speed of 2037.75 m/s for the sound wave.
Explanation:The speed of a sound wave is calculated by multiplying its frequency by its wavelength using the formula v = f λ, where v is the speed of the wave, f is the frequency, and λ (lambda) is the wavelength.
Given that the frequency of the sound wave is 627 hz and the wavelength is 3.25 m, we can substitute these values into the formula to find the speed:
v = 627 hz × 3.25 m
Now, let's perform the multiplication to solve for v:
v = 2037.75 m/s
Therefore, the speed of the sound wave is 2037.75 meters per second.
What is the volume of this right triangular prism?
Answer:
To calculate the volume of a triangular prism, measure the width and height of a triangular base, then multiply the base by the height by 1/2 to determine the triangle's area. Next, measure the height of the triangular prism and multiply this by the triangle's area to get the volume.

A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 11 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram: rectangle with length of x ft and width of x minus 4 ft, right triangle inside labeled stage with height of x minus 4 ft and base of 8 ft, rectangle inside labeled closet with length of 7 ft and width of 3 ft, the rest of the rectangle is labeled floor Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A). A = x(x − 4) − (8)(x − 4) − 3(7) A = x(x − 4) + (8)(x − 4) + 3(7) A = x(x − 4) + 0.5(8)(x − 4) + 3(7) A = x(x − 4) − 0.5(8)(x − 4) − 3(7)
Answer:
A = x(x − 4) − 0.5(8)(x − 4) − 3(7)
Step-by-step explanation:
x = length, making the width (x-4)
The stage closet will be (x-4)(8)(1/2)
The rectangle is 7(3)
That makes the painted area x(x-4) - 4(x-4)
So...
A = x(x − 4) − 0.5(8)(x − 4) − 3(7)
The printed area of the theater room is x(x − 4) − 0.5(8)(x − 4) − 3(7). Then the correct option is D.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 11 feet.
The width of the floor is 4 feet less than the length.
It will have a stage and a closet, and the remaining area of the floor will be painted.
Let, the length be x
Then the width will be (x - 4)
Then the stage closest will be
[tex]\dfrac{8(x- 4)}{2} \Rightarrow 4(x-4)[/tex]
The rectangle is 7(3)
The painted area will be given as
[tex]\rm x(x-4) - 4 (x-4)[/tex]
Then we have
[tex]\rm area = x(x - 4)- 0.5(8)(x - 4) - 3(7)[/tex]

What is the probability of landing on an even number? (Write your final answer as a percentage.)
P(event) =
The student council at Richmond High School
is made up of 646 female students 229
seniors, and 6% female seniors.
If a student is selected at random, what is the
probability, as a decimal to the nearest
hundredth, that the student is female given that
the student is a senior?
Answer:
[tex]P(F/S)=0.216[/tex]
Step-by-step explanation:
Let's call F the event that the student is female and S the event that the student is senior.
So, we need to find the probability P(F/S) that a student is female given that the student is a senior. P(F/S) is calculated as:
P(F/S) = P(F∩S)/P(S)
Then, the probability P(F∩S) that a student is female and senior is equal to 0.06
On the other hand, we can calculate the total number of students x using the following equation as:
[tex]\frac{646}{x}+\frac{229}{x}-0.06=1[/tex]
Where 646/x is the percentage of female students, 229/x is the percentage of senior students and 0.06 is the percentage of female seniors.
Then, solving for x we get that the number of students is 825.4719
Additionally, the probability P(S) that a student is a senior is equal to:
[tex]P=\frac{229}{825.47} =0.2774[/tex]
Because there are 825.47 students and 229 are senior.
So, P(F/S) is equal to:
[tex]P(F/S)=\frac{0.06}{0.2774}=0.216[/tex]
A ribbon that is 22 3/4 inches long has to be divided into 7 equal pieces
Answer:
each piece will be 3 1/4 inches
Step-by-step explanation:
22 3/4 can be rewritten as 91/4. to divide, you use keep, change, flip (keep the first fraction, change the sign, and flip the second fraction) . u will end up with 91/4 times 1/7, which is 91/28 or 3 1/4
Each piece of ribbon will be 3(1/4) inches.
What is expression?Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.
[tex]22\dfrac{3}{4}[/tex]
This expression can be rewritten
[tex]\dfrac{88+3}{4} = \dfrac{91}{4}[/tex]
Since ribbon has to be divided into 7 equal pieces
[tex]\dfrac{\dfrac{91}{4}}{7}[/tex]
[tex]\dfrac{91}{4} \times\dfrac{1}{7}[/tex]

Determine the intercepts of the line.
Answer:
see explanation
Step-by-step explanation:
To find the x- intercept, where the line crosses the x- axis, let y = 0 in the equation and solve for x, that is
11x + 6 = 0 ( subtract 6 from both sides )
11x = - 6 ( divide both sides by 11 )
x = - [tex]\frac{6}{11}[/tex] , thus coordinates of x- intercept are
( - [tex]\frac{6}{11}[/tex], 0 )
To find the y- intercept, where the line crosses the y- axis, let x = 0 in the equation and solve for y, that is
y = 11(0) + 6 = 0 + 6 = 6, thus coordinates of y- intercept are
(0, 6 )

Sonya wrote each letter of LEDBETTER on a separate index card and put the cards in a box. She picked one letter at random, put the card back, and then repeated the experiment. If she performed this experiment 90 times, which is the best prediction for the number of times that Sonya would pick a T?
Answer: 20
Step-by-step explanation:
Given, Sonya wrote each letter of LEDBETTER on a separate index card and put the cards in a box.
Total letters = 9
Number of times T appeared = 2
Thus, if we pick one card , the probability of getting card with T would be :-
[tex]\dfrac{\text{Number of times T appeared}}{\text{Total letters}}\\\\=\dfrac{2}{9}[/tex]
If she performed this experiment 90 times, then the best prediction for the number of times that Sonya would pick a T would be :
90 x ( probability of getting card with T)
[tex]=90\times\dfrac{2}{9}=10\times2=20[/tex]
Hence, the the best prediction for the number of times that Sonya would pick a T = 20.
