Answer:
-20
Step-by-step explanation:
cause i did the math hope this helped :D
430,500/ 750,000 = 0.574
0.574 x 100 = 57.4 %
(5x+15)(6x-10)
= 30x^2 + 30x - 50x - 150
= 30x^2 - 20x - 150
Answer:Thanks!
Step-by-step explanation:
The frequency of the emitted radio waves is:

The energy of a photon is given by:

where h is the Planck constant and f is the photon frequency. Using the frequency given by the problem, we can find the energy of each photon of this radiation:
