240 days is 4 times the half-life, which means that a sample of 1000 mg will decay to

after 240 days.
Answer:
40/3, 172/3, respectively
Step-by-step explanation:
x + 9 = 2y
2x = 2y + 2
x + 9 = 2(2x - 2)
4x - 4 = x + 9
3x - 13 = 0
x = 13/3
y = 40/6
RT = 13/3 + 9 = 40/3
QS = 160/3 + 4 = 172/3
Answer: v = u= 
Step-by-step explanation:
v= cos45 * 4= 
- Apply Pythagorean theorem
= 
We have u = 
it is definitely the answer B
