Explanation:
Finish the Given statement, make use of the relationships of angles and parallel lines, then finish the algebra.
__
2. m∠6 = (1/8)m∠4 . . . . Given
3. m∠6 + m∠4 = 180° . . . . 3. same-side interior angles are supplementary
4. m∠6 + 8·m∠6 = 180° . . . . 4. Substitution (from 2, above: 8·m∠6 = m∠4)
Here is the "algebra" that gets you to line 5:
4a. 9m∠6 = 180° . . . collect terms
4b. m∠6 = 20° . . . . . divide by 9
4c. m∠4 = 8·20° = 160° . . . use the same relation as in step 4
5. m∠6 = 20°, m∠4 = 160° . . . . Algebra
So the number of orders in is y=x+2, and going out is y=2x-1. The solution, which is x=3, represents when the number of order in is the same as the number of order out.
Our principal is $70. The rate is 12%
It can only be assumed that it's compounded once a year and it is invested for 4 years.
Therefore, using the equation:
P(1+r/n)^nt
We have 70(1 + .12/1)^(1)4
simplify for your answer:
70(1.12)^4
110.1464
C=2*pi*r
C=d*pi
d=8.4
C=(8.4)pi
8.4*pi
