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!

Answers

Answer:

A. 56

Step-by-step explanation:

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!)

210=157-w

solve for w

Answers

W=367 because 210+157 is 367 so 367 minus 157 would be 210 so I think w=367. The equation is just written backwards

Answer:

-53=w

Step-by-step explanation:

210=157-w

Subtract 157 from both sides

53=-w

-53=w

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
