A chemistry teacher needs to make a 42% sulphuric acid solution. The acid solutions available are 4 liters of 30% sulphuric acid and 50% sulphuric acid, by volume. How many liters of the 50% sulphuric acid solution must be mixed with the 4 liters in order to make the 42% sulphuric acid solution?
Answer:
4 liters of 30% and 6 liters of 50% acid.
Step-by-step explanation:
Let the volume of 30% acid be x, then the volume of 50% acid will be
(10 - x) liters.
So we have the equation:
0.30x + 0.50(10 - x) = 0.42* 10
0.30x + 5 - 0.50x = 4.2
0.80 = 0.20x
x = 4 liters.
So we need 4 liters of 30% acid and 6 liters of 50% acid.

HELPPP! ALMOST DUE! Clara estimated that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s actual height is 4 feet, 2 inches. What was the percent error for Clare’s estiamate? PLZ HELP!!!
Answer:
Her error in terms of inches was 2 inches while her percent error was 4.166%
Step-by-step explanation:
From the given data Claire estimated her brother to be shorter than he actually was. She estimated his height to be 4 feet while it was actually 4 feet 2 inches.
We convert the feet into inches because 12 inches are equal to a feet.
4 feet = 4 × 12 inches = 48 inches
4 feet 2 inches = (4 × 12 inches) + 2 inches = 48 + 2 = 50 inches
Error in terms of inches = 50 inches - 48 inches = 2 inches.
Step 2 ; Her percent error is given by dividing the difference in values by the actual value multiplied by 100.
% error = (difference in values / actual value) × 100
Claire's % error = (50 - 48)/ 48 × 100 = 2/48 × 100 = 0.04166 × 100 = 4.166%
Answer:
A 4% difference
Step-by-step explanation:
Convert 4 feet 2 into 4.16666666
4/4.16666666= 0.96 or 96%
4 feet was 96% of 4 feet 2 in
100 - 96= 4%
And this shows that there was a 4% error.
Hope it helped!

can you guys help me for 10 point Which of the following gives the correct domain and range for the relation graphed? i provide a picture of the graph so use it to answer pls
A. Domain: { x > –2 }, Range: { y > 1}
B. Domain: { x –2}, Range: { y 1}
9514 1404 393
Answer:
D. Domain: {x ≤ -2}, Range: {x ≥ 1}
Step-by-step explanation:
The graph extends to the left and above the point (-2, 1), which is included in the graph.
The domain is the horizontal extent. That will be all numbers less than or equal to -2.
The range is the vertical extent. That will be all numbers greater than or equal to 1.
Domain: {x ≤ -2}, Range: {x ≥ 1} . . . . matches choice D

Can someone help me find the Slope to these to pleaseeee?
Answer:
Remember the slope formula:
m= y2-y1/x2-x1
11. (-1,3) (3,3)
= 3-3/3--1
= 0/4
m = 0
12. (1,3) (1, -2)
= -2-3/1-1
= -5/0
= undefined
For the future, know that the slope of horizontal lines is always zero and the slope of vertical lines is always undefined.
