Answer:
1:25
Step-by-step explanation:
Given
<u>Dimensions of swimming pool:</u>
<u>Dimensions on paper:</u>
<u>Scale is the ratio of same measurements:</u>
- w/W = 8 cm/2 m = 8 cm / 200 cm = 1/25
So the scale is 1:25
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:
Tax = 7 1/4% = 29/4
After tax, it would be, 89.79 + 89.79*29/4*100 = 89.79 + 2589.41/400
= 89.79+6.47 = $96.26
