Answer:
3
Step-by-step explanation:
Wavelength is usually denoted as letter lambda (λ); it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): λ = v/f. Waves of different wavelengths.
formula: λ = v/f
solution: λ= 30m/s / 10Hz
= 3
Answer:4
Step-by-step explanation:
B) -7x-2x= -20-16
-9x= -36
X= -36 /-9
X= 4
About 0.5 percent per year
After converting to common denominator:
8/18, 7/18, 6/18, 5/18
so the next fraction is 4/18, but if you have to simplify it’s 2/9
No, because they're in the same place value.
