Answer is 10.5 miles
I used Pythagorean theory to solve for the unknown distance from the waterfall to lookout point.
a^2 + b^2 = c^2
2^2 + 4^2 = c^2
20 = c^2
Take square root of both sides
4.47 = c
Rounded to 4.5 miles
Add 4 miles and 2 miles and 4.5 miles
10.5 miles total
At the same rate, the price of 12 bottles of water at the convenience store would be
(12/10)·$11.80 = $14.16 . . . . . this is more than $13.80
On average the cost for the same number of bottles of water is higher at the convenience store. The grocery store has the better buy.

25*4=100 so,9*4=36
9/25=36%
Answer: C. A rectangle.
Step-by-step explanation:
1. By definition, a cross section is the intersection of a plane and a body of three dimensions.
2. A pentagonal prism has a pentagon as its base and its lateral faces are rectangles.
3. If the pentagonal prism is cut by a plane perpendicular to the base, this means that the plane is parallel to lateral faces, then, the shape of the cross section that is formed is also a rectangle.
4. The answer is the option C.
