Let volume of 4% solution = x and of 14% be y
them x + y = 65........(1) also using the actual weights of salt:-
0.04x + 0.14y = 65*0.06 = 3.9
multiplying the above equation by -25 we have
-x - 3.5y = -97.5 adding this to equation (1)
--2.5y = -32.5
y= 13
and x = 65 - 13 = 52
so we need 13 mls of the 14%, and 52 mls of the 4% solution.
Answer:

Step-by-step explanation:

Side z is the adjacent, since it is next to the angle you are solving for.
Side x is the opposite, since it is opposite the angle you are solving for.
The side measuring 14 is the hypotenuse, since it is across from the right angle.

Answer:
see below
Step-by-step explanation:
translated 3 units down whic means -3 on the y
hence T1 (2,0), T2 (-4,-8), T3 (-2, 1)
Answer:
20.5
Step-by-step explanation:
Let's label the vertices ABC as in the diagram below. Then
Data:
α = 34 °
β = 90 °
c = 17
Calculation:
cosα = AB/AC
Multiply each side by AC
ACcosα = AB
Divide each side by cosα
AC = AB/cosα = 17/cos34 ≈ 17/0.8290 ≈ 20.5
