Answer: E. 4/5
Step-by-step explanation: You have to put the decimal (0.8) over its place value. So in this case 0.8 turns into 8/10. Then you must simplify 8/10, by dividing the numerator (8) and the denominator (10) by the greatest common factor (2). Which gives you the answer 4/5.

Step-by-step explanation:
Answer:
5.0
Step-by-step explanation:
Using Pythagorean Theorem:
a² + b² = c²
where a =? b= 12 in and c = 13 in
a² + (12)² = (13)²
a² + 144 = 169
a² = 169 - 144
a² = 25
a = √25 = 5
∴ a = 5.0
Pythagoras Theorem is usually applied when finding one missing side of a right-angle triangle.

Answer:</h2>
<h2>
Explanation:</h2>
<em>The height of the rider from the ground after the Ferris wheel</em> equals <em>the starting point is 15 feet off the ground </em><em>plus </em><em>the radius of the Ferris wheel </em><em>plus </em><em>the opposite side of the triangle ΔABC </em>(See figure below).<em> </em>Hence our goal is to find this side. We have the angle 
, therefore the angle ∠BAC = 165° - 90° = 75°. So this side can be found using trigonometry:
Finally, the height is:
