Given that amount of first acid solution = 4 liters
Let concentration of the first acid solution = x
then effective amount of first solution = 4x
Given that amount of second acid solution = 10 liters
Givn that concentration of the second acid solution = 40% = 0.4
then effective amount of second solution = 0.4(10)
Then amount of resulting acid solution = (4+10) liters
Givn that concentration of the resulting acid solution = 30% = 0.3
then effective amount of resulting solution = 0.3(4+10)
Combining all those results gives equation
4x +0.4(10) = 0.3(4+10)
4x +4 = 0.3(14)
4x +4 = 4.2
4x = 0.2
x=0.05
Hence final answer is 0.05 or you can say 5%.
Answer:
D) (0.59, 3.35)
Step-by-step explanation:
The inequality for the thickness of the metal bars is:
In order for this inequality to be true, the following conditions must be met:
The range of thickness "x" that fits the inequality is:
Thickness ranges from 0.59 to 3.35 units.
Answer: 4.5y
Step-by-step explanation: You have To Multiply 15 times 0.3 and you get 4.5y
So you subtract $22.89 from $54.73 to get a total of $31.84 and that’s how much the customer paid.
