The answer is A because when you add the angles to get they equal 180. Then just solve for x.

Answer:
a. $45.54; b. $51.42; c. See below
Step-by-step explanation:
a. 193 min
Service charge = $40.00
1st 100 min @ 0.021 = 2.10
Next 93 min @0.037 = <u> 3.44
</u>
Total = $45.54
b. 317 min
Service charge = $40.00
1st 100 min @ 0.021 = 2.10
2nd 100 min @ 0.037 = 3.70
117 min @ 0.048 = <u> 5.62</u>
Total = $51.42
c. Piecewise function
The charge is
- $40.00 + 0.021t if t ≤ 100
- $42.10 + 0.037(t - 100) if 100 < t ≤ 200
- $45.80 + 0.048 (t - 200) if t > 200
which we can write like this:

8 dogs are still alive because you take away 4 from 12 which equals 8

Answer:
C.8.12 units
Step-by-step explanation:
Given the coordinates of two points:

The distance between these points is determined by the following equation:

We can extract the exact coordinates from the graph provided by the problem:

Therefore:

I don't see the correct answer from the choices given. So I would say the most aproximate is C.
