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.
If these points lie on the same line or coincides. then there are dozens of planes, passing through these points.
If these point don't lie on the same line, then there is unique plane, which passes through these points.
