1 L of a 78% acid solution was mixed with 6 L of a 64% acid solution. Find the concentration of the new mixture.
JulijaS [17]

The first solution contributes 0.78*1 = 0.78 L of acid.

The second contributes 0.64*6 = 3.84 L of acid.

There will be 7 L total of the new solution, and 3.84 + 0.78 = 4.62 total L of acid in it. So the new solution has a concentration of 4.62/7 = 0.66, or about 66%.

Determine if the ordered pair (6, 4) is a solution to the inequality
kvasek [131]

Answer:

A

Step-by-step explanation:

all we need to do is to plug the point (6,4) in the inequality and see if it satisfies it :

pay attention that here we have x=6  y=4

4<\frac{3}{4} (6) - 3

we simplify we get :

4<4.5-3  

4<1.5  which is incorrect  so (6,4) is not a solution. moreover

notice that 4 is > than 1.5  so the point lies above the line

thus the answer is : A

you can also solve this problem by graphing the line y=\frac{3}{4} x-3  and plotting the point (6,4)  and hence you will notice that the point is above the line
