Allison needs 18 liters of 5% saline solution . she has a 1% solution available. how many liters of the 1% solution and how many liters of the 10%solution should she mid to make the 5% solution

10 litres of 1% solution and 8 litres of 10% solution

Step-by-step explanation:

Let vol of 1% solution = x

So vol of 10% solution = 18 - x

5% of 18 litres = 0.9

Equation formed is

x + (18 - x)10 = 0.9 * 100

x + 180 - 10x  = 90

-9x = 90 - 180

-9x = -90

 x = 10 litres

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
