Answer:
Step-by-step explanation:
Final concentration % = [grams of salt / mililiters of solution] * 100
grams of salt = grams of salt from solution 1 + grams of salt from solution 2
grams of salt from solution 1 = mililiters * %/100 = 80 mililiters * 0.25 g/mililiters = 20 g
grams of salt from solution 2 = mililiters *%/100 = x*0.10 g/mililiters = 0.1x
mililiters of final solution = mililiters from solution 1 + mililiters from solution 2
mililiters of final solution = 80 mililiters + x mililiters
=> Final concentration, % = [0,10x + 20 g] / [x + 80 mililiters] * 100
Draw a tape diagram and make 18 sections on the diagram. Shade in the first section and that’s 1/18
I'm not too sure but i think:
A
_ r = x
Y
I believe this is Pythagorean theorem
The equation is
a^2+b^2+=c^2
In this case the equation would be
6^2+4^2=c^2
36+16=c^2
52=c^2
c=7.21110255093
