Answer:
Quantity of solution B required is 300 ml
Step-by-step explanation:
Let "a" be quantity of solution A required
Let "b" be quantity of solution B required
We are given Solution A is 19% alcohol and Solution B is 14% alcohol and that the resulting mixture has 156 milliliters of pure alcohol
Thus;
0.19a + 0.14b = 156 - - - (eq 1)
Also, He uses twice as much Solution A as Solution B.
Thus;
a = 2b
Putting 2b for a in eq 1 gives;
0.19(2b) + 0.14b = 156
0.38b + 0.14b = 156
0.52b = 156
b = 156/0.52
b = 300 ml
Quantity of solution B required is 300 ml
294 dollars
Okay so you would take 19.50 and add the 5 dollar insurance giving you 24.50. Then you’d take the 24.50 and multiply it by 12 giving you 294 dollars
Really hope I got that right
0.10 > 0.09 It is greater than.
Well, both variables appear to be negative, and the only option present that equals -20 is option A
Answer:
45 = 45
or
just 45.
Step-by-step explanation:
a = 6 , b = 2
3(6) + 4(2)^3 - 5 = 3(6) + 4(2)^3 - 5 (Given)
18 + 32 - 5 = 18 + 32 - 5 (Solve parenthesis)
45 = 45 (combine like terms)
45 does equal 45 so there is the solution. There is infinite many solutions.
