Answer:
C.
Step-by-step explanation:
❌Option A is incorrect
Rationale: from the graph, 1 hr on the x-axis doesn't correspond to $100 on the y-axis
❌Option B is incorrect
Rationale: from the graph, 2 hrs on the x-axis doesn't correspond to $200 on the y-axis. It can't also be the unit rate because unit rate would be the amount of dollars per 1 hr.
✅Option C is CORRECT
Rationale: from the graph, 8 hrs on the x-axis corresponds to $500 on the y-axis
❌Option D is incorrect
Rationale: from the graph, 4 hr on the x-axis doesn't correspond to $300 on the y-axis
C = to squares diagonal length
Pythagoras theorem: a^2 + b^2 = c^2
5^2+5^2=c^2
25+25=c^2
50=c^2
square root so c would be about 7.071
Since the diagonal is less than the diameter of the circle, the square will fit inside without touching the edge
This is true. Test it, 10 is divisible by 5 and 10. 20 is divisible by 5 and 10. If you continue you will see this to be true.
