58.3333333333
Step-by-step explanation:
Answer:
52 Hz
Step-by-step explanation:
We can divide the speed by the wavelength to find the number of waves propagated in one second:
(130 m/s)/(2.5 m/wave) = 52 waves/s
The SI unit of frequency is the Hertz, equal to one cycle per second.
The frequency of this wave is 52 Hz.
_____
<em>Additional comment</em>
The use of the unit Hz to signify frequency was adopted in 1933, but did not replace the unit "cycles per second" (CPS) until a number of years later.
The answer your looking for is 33.3%
(it goes on a lot longer but that's just rounded to 1 decimal place)
Answer:
C= 7y +150
850
250
Step-by-step explanation:
The cost is 7 times y, the number of yearbooks, plus 150, the upfront cost.
7 times 100 is 700, plus 150 is 850.
1900-150 is 1750 divided by 7 is 250
