Meaning that there will be 236 full racks and the last rack will only have 10 cds
<u><em>Answer:</em></u>
(c) 4.1 km
<u><em>Explanation:</em></u>
We are given that the height of the balloon is 4 km and that it is 1 km away from the station.
Setting up the diagram that describes the given scenario, we would end up with a right-angled triangle as the one shown in the attached image
<u>where:</u>
height of the balloon = 4 km represents one side of the triangle
distance between the base of the balloon and the station = 1 km represents the other side
distance between the balloon and the station is the length we want to find and it represents the hypotenuse of the triangle.
<u>To get the length of the hypotenuse, we will use the Pythagorean theorem</u>
![hypotenuse = +\sqrt{(side1)^2 + (side2)^2}](https://tex.z-dn.net/?f=hypotenuse%20%3D%20%2B%5Csqrt%7B%28side1%29%5E2%20%2B%20%28side2%29%5E2%7D)
<u>Substitute with the givens:</u>
= √17 ≈ 4.1 km
Hope this helps :)
