Answer:
b ≈ 101.52
Step-by-step explanation:
Given two sides and the angle between, the Law of Cosines is useful.
b^2 = a^2 +c^2 -2ac·cos(B)
b^2 = 105^2 +9^2 -2·105·9·cos(65°) ≈ 10307.251
b ≈ √10307.251
b ≈ 101.52
(4.55 x 10^13)-(1.78 x 10^12)=4.372 x 10^13
45500000000000
- 1780000000000

43720000000000 or 4.372 x 10^13

Answer:

Step-by-step explanation:
add/subtract the terms with same power of variable

The inequality for this problem is
200 - 2w < 175 => 2w > 200-175 => 2w > 25 => w > 12.5
The conclusion is that Ryan will have less than 175 lbs after 13-th week.
Good luck!!!
