A 5% destroys solution is given intravenously. Suppose a total of 2.64 L of the solution is given over a 19-hour period. What is
kow [346]

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 =

2.64\times 1000 = 2640\text{ ml}

Time period = 19 hour

Unit rate of flow =

=\dfrac{\text{Volume}}{\text{Time period}}\\\\=\dfrac{2640}{19}\\\\=138.95\text{ mL per hour}

Thus, the flow rate is 138.95 mL per hour.

Writing an equation and drawing it's graph to model a real world
avanturin [10]
The answer to the equation is 

y=1700s+18n  and y is the total salary including monthly and number books sold

then to graph it just plug that equation I gave you into your graphing calculator and it will show you the graph. Or you can do it by hand and just make a S and N table and plug in values like starting with 0 or 1 and go up 0,1,2,3,4,etc. for each S and P and you will get the corresponding graph coordinate points to plot. Hope this helps! Please rate thank you!!
