<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>

<u>Substitute with the givens:</u>
= √17 ≈ 4.1 km

Answer:
$5 bill
Step-by-step explanation:
If Rhonda has $13 and she has a $5 bill and 3 $1 bills, then she has
5 + 3(1) + x = 13
5 + 3 + x = 13
8 + x = 13
x = 5.
The last bill must be a $5 bill to equal the remaining $5.
