Three miles a day should be the correct answer
Step-by-step answer:
This is a regular heptagon, means it has 7 <em>congruent</em> sides and 7 <em>congruent </em>vertex angles.
To work with polygons, there is a very important piece of information that you must know to solve the majority of related problems.
This is:
sum of exterior angles of polygons = 360 degrees.
If you don't remember the 360 degrees, think of the sum of exterior angles of an equilateral triangle, which is 3*(180-60)=3*120=360! It works!
For a regular heptagon, c = 360/7=51.43 degrees approx.
This means that each vertex angle measures
vertex angle = 180-c
So since 2d+the vertex angle = 360, we have
2d+(180-c)=360
solve for d:
2d=360-(180-c)=180+c
d=(180+c)/2=90+c/2=115.71 degrees. (approx.)
<em>To solve for a variable, you just need to isolate the variable to one side.</em>
<h3>7.</h3>
For this, just divide both sides by r and <u>your answer will be 
</u>
<h3>8.</h3>
For this, divide both sides by nR and <u>your answer will be 
</u>
<h3>9.</h3>
Firstly, multiply both sides by T: 
Next, subtract FV on both sides of the equation: 
Lastly, multiply both sides by -1, and <u>your answer will be 
</u>
<h3>10.</h3>
Firstly, multiply both sides by 1000: 
Lastly, divide both sides by tc and <u>your answer will be 
</u>
Each year it will gain $10 so it will take 50 years.
1,000 × .02 = 20
1,000 ÷ 20 = 50
