The wave length of the sound with parameters frequency of 125 Hz and a speed 5000 m/s is 40 meters
<h3>Given Data</h3>
velocity = 5000 m/s
frequency = 125 Hz
wavelength = ??
We know that the relationship between speed, frequency and wavelength is given as
v = fλ ----------------------------1
substitute our given parameters
5000 = 125 * λ
Divide both sides by 125
λ = 5000/125
λ = 40 m
Hence the wave length of the sound is 40 meters

Answer:
3 min per lap
Step-by-step explanation:
15 (minutes)/5 (lap)= 3 minutes
1st
90+55+x=180 (Angles inside a triangle equal 180 degrees) Solve for x
x = 35 degrees
2nd
2 non-adjacent angle in a triangle is equal to the exterior angles, therefore
25 + x + 15 = 3x + 10 Solve for x
40 + x = 3x + 10
-10 -1x -1x -10
<u>30 = 2x</u>
2
x = 15 degrees
Therefore angle ABC is x + 15 where x + 15
Therefore angle ABC = 30 degrees
Who ever hand wrote in those degrees/equations didn't really think it out because < A + <B should be greater than 90 not less than 90
