Can I have the answers please. I don’t remember this.

Final volume-Initial volume= Volume of object

Explanation:

I have done one, you can take that as a reference and solve all others similarly.

Here is an example on how to do it,

Take the volume of water on the container with the object and subtract it with the volume of vessel with only water.

You will find the volume of the object.

The only thing I've found was " No shock, just resigned grief" My thoughts would just remove the comma 

The rate of change is the same as the slope...u can use the slope formula : (y2 - y1) / (x2 - x1), with 2 sets of points...oraccording to ur graph, they want to know how many miles u can go for 1 hr. y/x60/1so they can go 60 miles in 1 hr...60/1 is ur unit rate.

To find the unit rate, you should find the slope.  In order to find the slope of this line, use the rise/run between two points technique.  For example the rise/run between points (2,120) and (3,180) is 60/1, or 60.  This means that in one hour the family's car drives 60 miles.

Hope the explanation helped!
