7. 2 1/10
2 1/2
1 8/9
1 8/11
1 3/4
8. 1 6/8 = 1 3/4

10. She can sell the material because she has 10.5 yds and it only requires 10 yds.
Ending Amount = Beginning Amount / 2^n
where "n" is the number of half-lives
n = 139 / 27.8 = 5 half-lives
Ending Amount = 7.6 oz / 2^5
Ending Amount = 7.6 oz / 32
Ending Amount = .2375 ounces

Answer:
Step-by-step explanation:
Begin with process of elimination: As seen on the graph, there is a discontinuity at x=3. this means that x>=3. so we can eliminate B and C
Now you can see that at x = 3, two things happen. When moving to the left, x<3. when moving tot he right x>=3 so because of this you can eliminate D. The answer is A
