PLEASE HELP!!! 30 POINTS!!! NEED ANSWERS. WILL MARK BRAINIEST. FLAGGING NON RELEVANT ANSWER Follow the directions to convert the

analog sound wave into a digital signal. The lines on the grid intersect at various points (x,y). For each whole number value of X, find the intersection point that is closest to the wave. Draw a small circle on that point, and record it’s Y value. The circles for the X values 0 through 3 are already done for you. Draw circles for the X values four through18. Write down all 19 Y values obtained by sampling the wave

I don’t know the answer
Sunny_sXe [5.5K]

Answer:

AC ≈ 12.9 cm

Step-by-step explanation:

Using the ratio

sin40° = \frac{b}{20}

Multiply both sides by 20

20 × sin40° = b, hence

AC = b = 20 × sin40° ≈ 12.9

20. The surface areas of two similar solids are 216 m² and 1014 m². The volume of the larger one is 2197 m³. What is the volume
Andrei [34K]

Answer:

  216 m³

Step-by-step explanation:

The ratio of linear dimensions is the square root of the ratio of area dimensions.

  s = √(216/1014) = √(36/169) = 6/13

Then the ratio of volume dimensions is the cube of that. The smaller volume is ...

  v = (6/13)³·2197 m³ = 216/2197·2197 m³ = 216 m³

The volume of the smaller solid is 216 m³.

Please help and thank you

Answer:

D) 130 workers

Step-by-step explanation:

We have the equation, <em>y = 2x + 40</em>, and <em>y, 300</em> (since the y-coordinate represents the # of bottles made), so we can solve for x, <em>the number of workers needed</em>.

Substitute: <em>300 = 2x + 40</em>

Subtract: <em>260 = 2x</em>

Divide: <em>x = 130</em>

Since x = 130 when y = 300, 130 workers are required to make 300 bottles in a day.
