The weight is proportional to the price. So if 10lb cost $18.24, quarter as much (2.5lb) would cost four times less($18.24÷4=$4.56).
The answers are option C) segment and option D) ray
<u>Step-by-step explanation</u>:
Line :
- A line has arrow mark in the two ends. So, the diagram is not a line.
Point :
- A point represents particular spot as a small dot. So, the diagram is not a point.
Segment :
- It is a piece of line that has two end points. This part of line is called line segment and it is shown in the picture. option C is correct.
Ray :
- A ray is a line with one endpoint and the other end extends with an arrow mark. So, the option D is also correct.
Ths solubility curve can be used to obtain the amount of salt dissolved (solubility).
<h3>What is the solubility curve?</h3>
The solubility curve is a plot of the solubility of a substance against the temperature. It serves the purpose of being used to show the solubility of a susbtance at different temperatures. This question is incomplete hence we can not be able to deduce the solubility of the salt at this temperature.
If the solubility curve has been ploted, then we can be able to estimate the solubility of the salt from the graph.
