Answer:
Attached is what the graph should look like
Step-by-step explanation:
Answer: 2 and three-fourths (2 3/4)
Step-by-step explanation:
11 * 1/4
1/4 = 0.25
0.25 * 11 = 2.75
.75 = 3/4
2.75 = 2 3/4
Answer:
relation ( but not a function)
Step-by-step explanation:
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.
