If you multiple 13 18=234 then subtract that by 13 18 203 that would be the area so 13 is less than 18
Answer:
Tamara's example is in fact an example that represents a linear functional relationship.
- This is because the cost of baby-sitting is linearly related to the amount of hours the nany spend with the child: the more hours the nany spends with the child, the higher the cost of baby-sitting, and this relation is constant: for every extra hour the cost increases at a constant rate of $6.5.
- If we want to represent the total cost of baby-sitting in a graph, taking the variable "y" as the total cost of baby-sitting and the variable "x" as the amount of hours the nany remains with the baby, y=5+6.5x (see the graph attached).
- The relation is linear because the cost increases proportionally with the amount of hours ($6.5 per hour).
- See table attached, were you can see the increses in total cost of baby sitting (y) when the amount of hours (x) increases.
S is 3 parts of R, or 9. 9 is 3/4 of 12, so R is 12. 12 plus 9 is 21, which is half of the full area of the rectangle. The area of the rectangle is 42 square centimeters. Now, we need to find what R is to the whole rectangle. We know that R is 12 square centimeters, and that the rectangle is 42 square centimeters. That ratio is 12 to 42. If it is simplified, that would be 6 to 21. If it is simplified further, you find that it is 2 to 7. Hope this wasn't too confusing, and I hope that I helped :)

Step-by-step explanation:
Co terminal angles are angle ± 2π, that is
+ 2π
=
+
= ![\frac{27\pi }{8}](https://tex.z-dn.net/?f=%5Cfrac%7B27%5Cpi%20%7D%7B8%7D)
and
- 2π
=
-
= - ![\frac{5\pi }{8}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5Cpi%20%7D%7B8%7D)
