<u>Answer:</u>
○B (second option)
<u>Step-by-step explanation:</u>
In the second option, we can see that the point T is at +1. The point R is between -7 and -8, therefore we understand that it is at a value of
.
All the other options have the points R and T at values not asked for in the question.
Answer: She jump ropes 7/3 or 2 1/3 of an hour every week
Step-by-step explanation: This is because she jump ropes 1/3 each day and there's 7 days in a week so 7/3 or 2 1/3(2 hours and 20 minutes)

Answer:
Mercury
Step-by-step explanation:
We'll translate this into ratios.
First, V:E = 0.943:1
Then, M:E = 0.983:1
We already have their density in terms earth's density. They are in the same unit. So, we can compare them directly, with greater ratio means greater density. It's clear that Mercury has the greater density.
Answer: velocity-time graph
Step-by-step explanation: The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).
