Answer:
The answer is 154.8 ml
Step-by-step explanation:
In this question, the amount of pure acid is 18% of the total solution, that is, 18% of 860 milliliters. So
0.18*860 = 154.8 ml
The answer is 154.8 ml
Since 16 - 29 are systems of equations, the easiest way would possibly be through elimination because all you'd have to do is add the two equations then solve for your variable then plug in that number to one of the equations and then solve for the remaining variable, and then you'd get an ordered pair as your solution.
Answer:
1/4
Step-by-step explanation:
2 to the power of -2 would be 1/4.
This is because 2 to the power of -1 would be 1/2. And the power of 2 would square the 2 as the denominator making it 1/4.
The reason -1 makes the 2 turn into a fraction is that to the power of 2 means 2x2, to the power of one means 2, The power of zero would therefore divide by 2 so 2/2 = 1 and so 2 to the power of -1 would be 1/2.
Answer:
1/4
Step-by-step explanation:
count rise/run to find the slope from A to B rise 1 from A and run 4 to B
m = 1/4
<u>Answer:</u>
x = 8
<u>Explanation:</u>
-x + 1 = -7 Subtract one from each side
-x = -8 Divide each side by -1 to get x by itself
x = 8
