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: H (131.125 ft^2)
Step-by-step explanation:
first, you need to find the area of the wall
wall:
A=Lw (length times width)
A= 9.75 x 15.5 (I changed them into decimals)
A = 151.125
now you need to find the area of the window
window:
A = Lw
A = 4 x 5
A = 20
now you need to subtract the area of the window from the area of the wall to find the amount of space you need to cover with wallpaper
151.125 - 20 = 131.125
Answer:
x= -2
Step-by-step explanation:
jk im just stealing points
11 foot wall,
the center of the wall would be 5 1/2 feet which is 5 feet 6 inches
the shelf is 2 feet 6 inches, so the center of that would be 1 foot 3 inches
5 ft 6 in - 1 ft 3 in = 4 ft 3 inches from corner
For this question, it would be most effective to use an algebraic expression to more easily show what the question is asking. If we use the variable "k" to show the distance in km that he cycled on Sunday, we know that the amount he cycled on Saturday equals k + 12, and the amount that he cycled on the weekend should be the amount of Saturday plus the amount of Sunday. If we write this as an equation we say:
k + k + 12 = 38
=> 2k + 12 = 38
Now we can just rearrange and solve for k:
=> 2k = 26
=> k = 26/2 = 13
Therefore Patrick cycled 13km on Sunday
To solve the answer, we just add 12km to the value for Sunday like so:
12 + 13 = the amount he cycled on Sunday
Hope this helped, remember to please try and understand the maths as well as the answer :))
