Answer 3

alright. I think I can help you

Answer 4

Okay thanks

Answer 5

do you need to show the conversion factors

Answer 6

No i just need it to be one of the choices listed above

Answer 7

100m= 0.621371 miles
11 seconds = 0.0030556 hours

v=d/t

\[0.0621371miles/0.0030556hour=20.3355 miles/hour\]
So with the significant digits the answer would be 20.3 miles/hour.
Therefore, this answer should be correct

Answer 8

Thank you also can you help me out with this if you can? Shelly and Terrence earned points in a game by completing various tasks. Shelly completed x tasks and scored 90 points on each one. The expression below shows Terrence's total points in the game:

90x - 20

What does the constant term of the expression represent?

The total points Terrence earned

The total number of tasks Terrence completed

The sum of Shelly and Terrence's total points

The difference between Shelly and Terrence's total points

Answer 9

I am not completely sure but I assume that it would be the difference between shelly and terrences total points because shelly scored 90 points in x amount of tasks so if the expression shows terrences amount of points in the game, I assume that he scored 20 points. So I think that is why the answer is so if thAT MAKES SENSE
