Answer:
The correct answer is 0.0667 centimeters.
Step-by-step explanation:
Diameter of earth is 12700 kilometers.
Width of the solidified ocean crust is 35 kilometers.
Ratio between the diameter of the earth and the solidified crust is 
.
Now the earth is shrunken to a size of a basketball with the diameter as 24.2 centimeters. Let the thickness of the Earth's crust in this model be x centimeters.
Ratio between the diameter of the model earth and the solidified crust is 
.
But this ratio of the real Earth and its model must be equal.
∴ =
⇒ x = 0.0667 centimeters.
1st day= $5
2nd day = 5^2 = $25
3rd day = 25×3= $75
5 + 25 + 75 = $105

Answer:
Step-by-step explanation:
<em>See the attached</em>
All given details are reflected in the diagram (not to scale)
- PA is at 225°, PB is at 116°, BA is at 258°
- AB = 3.9 km
- AP = x
- m∠P = 225° - 116° = 109°
- m∠A = 258° - 225° = 33°
- m∠B = 180° - (109° + 33°) = 38°
<u>Use the law of sines:</u>
- x/ sin 38° = 3.9 / sin 109°
- x = 3.9 sin 38° / sin 109°
- x = 2.54 km (rounded)
