The sentence that is punctuated correctly is:

"After driving all day and night, we finally reached our destination, and we happily went to sleep."

The other sentences contain punctuation issues:

  1. "in 2019 eight new students enrolled in our school..." - should have a comma after "2019."
  2. "for about 3 minutes, the helicopter hovered overhead, and then flew away, to the east." - the comma after "away" is unnecessary.
  3. "on monday i am going to go hiking but after that i will come by to visit you." - should capitalize "Monday" and "I," and it might be clearer with a comma before "but."
which sentence is punctuated correctly?

"Please hand out the worksheets to the students'," the teacher told me.
"Those science projects are the seventh graders'," he instructed.
"That dog is the Jones'," my neighbor said.
"Those backpacks are my sisters;," Callie said.

The sentence that is punctuated correctly is:

"Those science projects are the seventh graders'," he instructed.

The other sentences have punctuation or grammatical issues:

  1. "Please hand out the worksheets to the students'," the teacher told me. - The possessive form is incorrect here; it should be "students."
  2. "That dog is the Jones'," my neighbor said. - The possessive form is also incorrect; it should be "Joneses" for plural possessive.
  3. "Those backpacks are my sisters;," Callie said. - The semicolon should not be there; it needs to be a comma instead. It should be, "Those backpacks are my sister's," Callie said.
which sentence correctly used punctuation with a subordinating conjunction?

Because you offered to help.
because of you, i was able to get the help i needed.
you came over: because i needed some help.
i got the help i needed; because i needed some help.

The sentence that correctly uses punctuation with a subordinating conjunction is:

"Because you offered to help."

The other sentences have punctuation issues:

  1. "because of you, i was able to get the help i needed." - The sentence should start with a capital letter: "Because of you, I was able to get the help I needed."
  2. "you came over: because i needed some help." - The colon is inappropriate; it should just be a comma: "You came over because I needed some help."
  3. "i got the help i needed; because i needed some help." - The semicolon is incorrect; it should not be used before "because." It should simply be: "I got the help I needed because I needed some help."
which sentence correctly used punctuation with a subordinating conjunction?

  3. "I got the help i needed; because i needed some help." - The semicolon is incorrect; it should not be used before "because." Additionally, "i" should be capitalized: "I got the help I needed because I needed some help."

So, the first sentence is the only one correctly punctuated with a subordinating conjunction.
