Let x% be the salt concentration of first solution.
Then in 8ml, amount of salt = 
Given that to this 8ml solution, 11ml solution of a 47% salt solution is mixed.
amount of salt in 11ml of 47% salt solution is = 
So, total amount of salt in new mixture = 
But given that this new solution is a 43% salt solution.
Hence amount of salt in new mixture of (8+11)=19ml solution of 43% salt solution is 
Hence 
8x+517 = 817
8x=817-517 = 300
x= 300/8 = 37.5
Hence the salt concentration in the first solution is 37.5%

Step-by-step explanation:
12 divided by 25 is 0.48.
Answer:
6.7 %
which agrees with answer A in your list.
Step-by-step explanation:
If the standard volume is 1.5 cubic cm, and the measured volume is 1.6 cubic cm, then the difference between these two is :
1.6 - 1.5 = 0.1 cubic cm. and therefore the percentage error is given by:
0.1/1.5 = 0.066666...which corresponds to a rounding of 6.7%
Recall as well that percent error is always expressed as a positive number.
Answer:
The Answer is 1/4 hope it helps
Step-by-step explanation:
The roots of the quadratic equation are:
x = 0.74 - 0.6614i
x = 0.74 + 0.6614i
The given equation is:
2x² + 2 = 3x
Rearrange the equation
2x² -3x = -2
Divide through by 2
x² - (3/2)x = -1
x² - (3/2)x + (3/4)² = -1 + (3/4)²
(x - 3/4)² = -7/16
Square root both sides
x - 3/4 = √(-7/16)
x = 3/4 ± √(-7) / 4
x = 0.75 ± i√(7) / 4
x = 0.74 ± 0.6614i
Therefore, the roots of the quadratic equation are:
x = 0.74 - 0.6614i
x = 0.74 + 0.6614i
