Answer:
It's number one.
Step-by-step explanation:
This is because all the other answers are opinions, like the most attractive color one. Everyone has a different favorite color. But number one is something that can be proved. That's what you're looking for in the scientific method.
Answer: The length and width are 50 and 30 meters (or 30 and 50 meters).
Step-by-step explanation:
To solve this question, we can represent variables for the length and width in two equations.

To solve for one of the variables, you'll have to substitute one of the variables, so solve for one of them:


Now, we have a standard quadratic equation that we can factor. When factoring, you'll get this:

This tells us that the width could be either 50 or 30.
Substitute 50 into one of the equations to find the length:
2 (l) + 100 = 160
l = 30.
The length and width are 50 and 30 meters (or 30 and 50 meters).
Im pretty sure it would be Ariel.
Tamar reads 600 words in 5 minutes, so he is already out of the question since Levi reads 700 words in 5 minutes. (Levi reads 140 words in 1 minute, so add 140+560=700 because they read 560 in 4 minutes)
So I think it’s Ariel because in 4 minutes she reads 600, and where the 5 would be, if you go straight up, it’s over 700 (if i had to guess, 750 since it’s counting by 100s and it would be in the middle of 700 and 800)
