Answer:
Step-by-step explanation:
1. Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz.
2. speed of sound is 343 m/sec.
3. two animals are Bats and Whales.
4.The voiced speech of a typical adult male will have a fundamental frequency from 85 to 180 Hz, and that of a typical adult female from 165 to 255 Hz.

The answer is ≈0.524... so, none of the above?
Start by moving the three to the other side of the equation. Do this by subtracting 3 from both sides, so you get 21x=11.
Next, divide both sides by 21. This will give you x=11/21, which is ≈0.524.
However, I do not see this as one of the answers. I get why you might be confused!
The slope is always rise/run and has a variable. In this case, 2/3x is the slope.
The y-intercept is always the number at the end, which is the y-value. This would mean that 5 is the y-intercept.
Answer:
31r-71
Step-by-step explanation:
=> 6(5r-11)-(5-r)
=> 30r-66-5+r
=> 30r+r-66-5
=> 31r-71
