Answer:
We need 8 ounces of solution A and 32 ounces of solution B.
Step-by-step explanation:
We are given that a scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt.
She knows that Solution A is 40% salt and Solution B is 65% salt.
- First condition states that she wants to obtain 40 ounces of a mixture that is 60
% salt, that means;
A + B = 40
B = 40 - A ------------ [Equation 1]
- Second condition states that Solution A is 40% salt and Solution B is 65% salt, that means;
{from equation 1}
A = = <u>8 ounces</u>
Now, putting value of A in equation 1, we get;
B = 40 - A
B = 40 - 8 = 32 ounces
Hence, we need 8 ounces of solution A and 32 ounces of solution B.

Step-by-step explanation:
Graph the boundary lines as though these were equations. For the first inequality, which does not include the "or equal to" case, the line is dashed.
Now, look at y in relation to the comparison symbol. For "y < ...", values of y that are in the solution set will be below (less than) those in the line, so the shading is below the line. For "y ≥ ...", values of y that are in the solution set will be above (greater than) those in the line, so the shading is above the line.

The graph of y=2x-1 has a slope of 2 and intersects the y-axis at y=-1. The graph of y=-x+3 has a slope of -1 and intersects the y-axis at y=3.
2x^-2y^-2 = 2/x^2y^2 = 2/(2)^2 x (3)2 = 2/4 x 9 = 2/36 = 1/18
Answer:1/15 or 0.06
Step-by-step explanation:
Divide 1/5 by 3 since there are 3 people sharing the bar.
