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?
Answers
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.

What are the slope and the y-intercept of the graph of the linear function shown on the grid?
Answers
Answer:
C
Step-by-step explanation:
Slope=rise/run
Y intercept is the where the line hits the y axis which is -1.5
Answer:
Slope: -1/4
y-intercept: -1.5
Step-by-step explanation:
First you do rise over run meaning you from the point (-2,2) you rise up 2 to reach the x axis which is where point -6,0 so you rise 2 points and run 6. since the line is negative it becomes -1/4 and y-intercept is where the line first touches the y-line which is -1.5. I hop this helps!

Answer:
The solution is:
a. -18
b. -18
c. 24
d. 0
e. -4
4. 4
Step-by-step explanation:
Before we get into the solution, we remember the formula first, namely:
Addition
• (-) + (-) = (-)
• (+) + (+) = (+)
Subtraction
• (+) - (+) = can (-) and (+)
• (+) - (-) = (+)
Multiplication
• (-) x (-) = (+)
• (+) x (-) = (-)
Division
• (-) : (-) = (+)
• (+) : (-) = (-)
Solution:
a. 6(-3) = -18 ((+) × (-) = (-))
b. -6(3) = -18 ((-) × (+) = (-))
c. (-8)(-3) = 24 ((-) × (-) = (+))
d. -8(0) = 0 (whatever the number, if multiplied by 0 the result is still 0)
e. -20÷5 = -4 ((-) ÷ (+) = (-))
f. -36÷(-9) = 4 ((-) ÷ (-) = (+))

The equation of line passes through the points (0, -5) and (5, -2) will be;
⇒ y = 3x/5 - 5
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (0, -5) and (5, -2).
Now,
Since, The equation of line passes through the points (0, -5) and (5, -2).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 2 - (-5)) / (5 - 0)
m = 3 / 5
m = 3/5
Thus, The equation of line with slope 3/5 is,
⇒ y - (-5)= 3/5 (x - 0)
⇒ y + 5 = 3x/5
⇒ y = 3x/5 - 5
Thus, The equation of line passes through the points (0, -5) and (5, -2) will be;
⇒ y = 3x/5 - 5

If you look at the image, I cut the shape in half.
So the shape on the bottom not can be multiplied as such: 8x2x2
8x2=16 then 16x2=32.
Since the shape cut in half, the sides are now 2 instead of 4.
Now you can multiply the top shape by: 2x6x2
2x6=12 then 12x2=24.
After you have the volume of both shapes, you add the volumes together.
32+24=56 Then your answer should be A. (Hope this helps!)
