Question
Chapter 1, Problem 18E
Interpretation Introduction
Interpretation:
The nine dot problem with three straight, continuous lines is to be solved and the unconscious assumption to solve the problem is to be identified.
Concept introduction:
A series of points joined in a straight way without any discontinuity is known as a straight and continuous line. A straight and continuous line is one dimensional in nature. Generally, it is not possible to join a two or three dimensional structure by a single straight and continuous line.

The human body burns glucose (C,H,O,) for energy according to this chemical reaction:
CH₁₂0+60-6CO₂
+ 6H₂0
The products of the reaction are carbon dioxide (CO₂) and water (H₂O).
Interestingly, all of the carbon dioxide and much of the water exits the body through the lungs: on every breath, the average person exhales
500 ml. of air, which is typically enriched to 4% CO, and 5% water vapor by volume. In short, when a person loses weight by dieting, the weight
that is lost actually departs his body as a gas, every time he exhales. Each kilogram of body fat lost requires exhaling about 2.8 kg of carbon
dioxide.
Calculate how many breaths it takes an average person to "exhale" 3.00 kg of fat. Round your answer to the nearest thousand.
You'll need to know that the density of CO₂ is 2.0 kg/m³.
