Answer:
5%
Step-by-step explanation:
820 - 779 = 41. 41/820 = 0.05. 0.05 = 5%
<h2>9x^4 - 6x^2 - 3x - 6</h2><h2 />
(9x^4-13x^3-x-7)+(7x^3-2x+1)
Sort the terms by their powers, as x's with the same powers can be added together:
9x^4
-13x^3 + 7x^3 = -6x^3
-x - 2x = -3x
-7 +1 = -6
<h2>9x^4 - 6x^2 - 3x - 6</h2>
I’m confused it says 131.796 and also 1,240,55. So idk which one’s are even correct. If you try asking the question again I can give you the answer
Ratio of A to B is 7:5...
so if there was 295 mL of compound B...
7 / 5 = a / 295
cross multiply
(5)(a) = (295)(7)
5a = 2065
a = 2065/5
a = 413 .... so 413 mL of compound A would be used
for a total solution of (295 + 413) = 708 mL solution <===
