You can't solve this without a total amount. Ask your teacher about this.
Answer:
The answer is C. 0.19 I hope this helped you good luck!
Answer:
y = (3 × 10^8 m/s)/x
Step-by-step explanation:
Speed of a wave is given by the product of wavelength and frequency.
Thus; speed = frequency × wavelength
If x = wavelength and y = frequency then speed will be;
speed = yx
Thus to get wavelength, y;
y = speed/x , but speed is 3 × 10^8 m/s
Thus;
y = (3 × 10^8 m/s)/x
7.225 because you putting 7 9/40 to 289/40
