Since the tuba creates a 4th harmonic of frequency 116.5 hz, the length of pipe in tuba is 6.57 m

Since the tuba is an closed-pipe instrument, we need to find the frequency of a closed pipe

The frequency of a closed pipe f = nV/4L where

Making L subject of the formula, we have

L = nV/4f

Since the tuba creates the 4th harmonic with frequency 116.5 Hz.

Substituting the values of the variables into the equation, we have

L = nV/4f

L = 9 × 340 m/s/4 × 116.5 Hz

L = 3060 m/s ÷ 466 Hz

L = 6.57 m

So, the length of pipe in tuba is 6.57 m

explanation:

percent. part

_______ = _____

100. whole

42. ?

____ = ____

100. 800

cross multiply

800×42=33,600

then divide by 100

33,600/100=336

Answer:

336

Step-by-step explanation:

If 42% said they shopped online last week, that means the number of people who said they shopped online last week is 42% of 800. "Of" just means we should multiply, and since 42% = 42/100 (since % is just /100), we can use the following to find the answer (I used cross multiplication to simplify):

42          800         42         8

---    *               =     ----    *       =     336

100                           1

The answer to the limitation of the Chi Square test (and all tests of hypothesis) about relationships between variables  is none of the above.

The Limitation of this type of test is in its sample size requirements, as there is a lot of difficulty of interpretation when samples are large.

Note that Chi Square test and all tests of hypothesis can tell us if relationships between variables are significant, random and also if it occurred by chance and as such they are no limitations here.

Therefore, option d is correct.

x = 60°

Step-by-step explanation:

x + 2x + x + 2x = 360

Angles in a parallelogram add up to 360°

6x = 360

x = 60°

Answer: 60

Step-by-step explanation: The angles of a parallelogram alway add up to 360 degrees. We can use this and set the 4 angles (2x,2x,x,x) equal to 360.

2x+2x+x+x=360

6x=360

The living room area of Monica's home is  0.645 ft².

The floor area of her current home is  1.3975 ft²

The total floor area of Monica's dream home should be 2.150 ft².

Monica wants the living room to be 30% of the total area. Therefore, the living room area will be as follows:

living room area = 30 / 100 × 2.150 = 64.5 / 100 = 0.645 ft²

Her current house has only 65% of the floor area of her dream house. Therefore, the floor area of her current home is as follows:

Floor area of her current home = 65 / 100 × 2.150

Floor area of her current home = 139.75 / 100

Floor area of her current home = 1.3975 ft²

[tex]-\frac{2}{3} x[/tex]

Step-by-step explanation:

Hey there!

To find slope, you take [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

In this case

y2: 6

y1: 4

x2: -3

x1: 0

Now we plug in this information

[tex]\frac{6-4}{-3-0} \\\\\frac{2}{-3} \\\\-\frac{2}{3}[/tex]

Since this is the slope, you have to add a "x"

ANSWER IS D

Answer:

(x + 7)/(x + 1)

Step-by-step explanation:

Simplify the following:

(x^2 + 11 x + 28)/(x^2 + 5 x + 4)

The factors of 4 that sum to 5 are 4 and 1. So, x^2 + 5 x + 4 = (x + 4) (x + 1):

(x^2 + 11 x + 28)/((x + 1) (x + 4))

The factors of 28 that sum to 11 are 7 and 4. So, x^2 + 11 x + 28 = (x + 7) (x + 4):

((x + 4) (x + 7))/((x + 4) (x + 1))

((x + 7) (x + 4))/((x + 4) (x + 1)) = (x + 4)/(x + 4)×(x + 7)/(x + 1) = (x + 7)/(x + 1):

Answer: (x + 7)/(x + 1)

Next time write the expression how it needs to be, the way you wrote it woould have given a toally different result.

x^2 + 11 x + 28/x^2 + 5 x + 4

Answer:

solving this as you would in algebra 2:

x2+11x+28 / x2+5x+4 = x+7 / x+1

Step-by-step explanation:

solving this as you would in algebra 2:

x2+11x+28 / x2+5x+4

1. on both the top and the bottom you have to find a factor of the last number (in this case 28 and 4) that multiplys to be the number but adds to be the 2nd term (11x and 5x)

2. for the top the two terms would be (x+7) and (x+4). on thebottom half it would be (x+4) and (x+1)

** 7 times 4 equals 28, 7 plus 4 equals 11; 4 times 1 equals 4, 4 plus 1 equals

3. x+4 is common term on both the top side and the bottom half so you cross it out. this leaves us with our answer of: x+7 over x+1

Answer:

4 true false and 8 short answer

Or 15 true false and 5 short answer

Or 26 true false and 2 short answer

Step-by-step explanation:

let x be the number of true-false questions

   y be the number of short-answer questions

Then we have to solve the equation 3x + 11y = 100

Important: x and y are natural numbers

3x + 11y = 100 ⇔  100 - 11y = 3x

If y=10 ⇒ 100 - 11×10 = −10  = 3x impossible because x ≥ 0

If y=9 ⇒ 100 - 11×9 = 1  = 3x impossible because x is a natural number

If y=8 ⇒ 100 - 11×8 = 12  = 3x ⇒ x = 12/3 = 4

Then (x,y) = (4,8) is a solution to the equation

If y=7 ⇒ 100 - 11×7 = 23  = 3x impossible because x is a natural number

If y=6 ⇒ 100 - 11×6 = 34  = 3x impossible because x is a natural number

If y=5 ⇒ 100 - 11×5 = 45  = 3x ⇒ x = 45/3 = 15

Then (x,y) = (15,5) is a solution to the equation

If y=4 ⇒ 100 - 11×4 = 56  = 3x impossible because x is a natural number

If y=3 ⇒ 100 - 11×3 = 67  = 3x impossible because x is a natural number

If y=2 ⇒ 100 - 11×2 = 78  = 3x ⇒ x = 78/3 = 26

Then (x,y) = (26,2) is a solution to the equation

If y=1 ⇒ 100 - 11×1 = 89  = 3x impossible because x is a natural number

If y=0 ⇒ 100 - 11×0 = 100  = 3x impossible because x is a natural number
