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 1/10 x (9a-23b)
answer is 1.566 deg
Step-by-step explanation:
The angle of elevation is given by the formula
tanθ = height/distance
tanθ = H/ 240
tanθ × 240 = H
θ =( tan∧-1) 240
= <u>1.566 deg</u>
1/3 is the same as 2/6, so we can rewrite this as:
-5/6 + 1/3 = -5/6 + 2/6
To add fractions, add the numerators:
-5 + 2 = -3
So, -5/6 + 2/6 = -3/6
This can reduce, since 3 and 6 are divisible by 3.
-3/6 = -1/2
