At sea, the distance D to the horizon is directly proportional to the square root of the elevation E of the observer. If a perso

<span>The problem says that the distance D to the horizon is directly proportional to the square root of the elevation E of the observer, so:
</span>
 The person who is 36 feet above the water ⇒ √36=6 

 A person 49 feet above the water ⇒ √49=7
<span>
 So, by proportions, you have:

 (7/6)x7.4= 8.63 miles

 Therefore, the answer is: </span><span>a person 49 feet above the water can see 8.63 miles</span><span> </span>

What is exactly the relation between a Rhombus, rectangle, parallelogram, and square explain please i will mark brainliest only
ch4aika [34]

Any rhombus is a parallelogram, but not the other way around. If you were to make a Venn Diagram, the "rhombus" portion is entirely inside the set of "parallelograms".

The same can be said about rectangles as well. Any rectangle is a parallelogram, but not the other way around.

If we overlapped the region of rectangles and rhombuses, then we form the region for squares. A square is a combination of a rhombus and a rectangle.

Any square has all four sides the same length (property of a rhombus) and all angles equal to 90 (property of a rectangle). Since a square inherits properties of a rectangle and rhombus, it automatically makes any square a parallelogram.

Check out the venn diagram below.
