Answer:
3.5 to 20.5 hours
Step-by-step explanation:
The range of the sine function is -1 to 1, so the range of H will be ...
-8.5 +12 = 3.5
to
8.5 +12 = 20.5
The length of the day varies by 17 hours from 3.5 hours to 20.5 hours.
Answer:
d ≤3
Step-by-step explanation:
9−4d≥−3
Subtract 9 from each side
9-9−4d≥−3-9
−4d≥−12
Divide by -4, remembering to flip the inequality
-4d/-4 ≤ -12/-4
d ≤3
Answer:
Books should be kept in second box.
Step-by-step explanation:
If the sum of all the weight of all books is between 4 and 6 pounds then it should be kept in first box
If the sum of all the weight of all books is between 5 and 7 pounds then it should be kept in second box
If the sum of all the weight of all books is between 8 and 9 pounds then it should be kept in first box .
Here sum of the weighs of all the books = 3.1lb+2.4lb +0.75lb
= 6.25 lb
Here we can see that 6.25 lb lies between 5 and 7 which is the weigh limit
for the second box
therefore we can keep the books in second box.
