She used 2.67 ounces of ice cream in the shake. (2/3) * 4 = 8/3 which is equal to approximately 2.67 ounces.
Since a slope differe, this is not linear relationship. Simply, if you connect all points on the graph, they will not lie on the same line. Two next graphs represent the linear relationships, so they represent the linear relationship.
Answer:
The flow rate is 138.95 mL per hour.
Step-by-step explanation:
We are given the following in the question:
Volume of solution = 2.64 L
1 L = 1000 mL
Volume of solution in mL =

Time period = 19 hour
Unit rate of flow =

Thus, the flow rate is 138.95 mL per hour.
So to to get 3% of 159 you: 159x0.03=4.77
