Step-by-step explanation:
Given:
Wavelength of wave : 3.3m
Frequency of wave : 100Hz.
speed/velocity : ?
As we know
velocity = wavelength × Frequency
= 3.3 × 100
=330ms−1
So the speed of the wave is 330 ms·¹
Answer:
the number is 25
Step-by-step explanation:
If the number is n, then twenty-two more is n + 22
which equals 47, so n+ 22 = 47
n = 47 - 22 = 25
The mean is the average of a set of numbers. You add all of your numbers together (example = 1+5+3= 9), then you divide the answer by the number of numbers you have used ( 9 divided by 3 = 3) so the mean is 3
