Answer: 42

Explanation:
First, you should divide both denominators to find what number you are multiplying by.

48/8 = 6

So now you know that the number you are multiplying by is 6. Now you want to multiply 7/8 by 6.

7/8 x 6 = 42/48

Hope this helped! :3

Answer:

42 should be in the blank.

Step-by-step explanation:

If you multiply 7/8 by 6, watch what happens...

7/8 *6 = 42/48

The denominators are the same, which shows how the equations are probably equal.

I know it might seem confusing because I'm not great at explaining, but I hope it helps! Have an awesome day c:

What is the slope of a line perpendicular to the line whose equation is 6x+2y=−32. Fully simplify your answer.
Reika [66]

The slope of the line that is perpendicular to 6x + 2y = -32 is: 1/3.

<h3>What is the Slope of Perpendicular Lines?</h3>

The slope of two lines that are perpendicular to each other will always have a product that is equal to -1, which means that their slopes are negative reciprocals to each other.

Rewrite 6x + 2y = -32 in slope-intercept form:

2y = -6x - 32

2y/2 = -6x/2 - 32/2

y = -3x - 16

The slope is -3. Negative reciprocal of -3 is 1/3.

Therefore, the slope of the perpendicular line would be: 1/3.

Snape has 2000 mL of a magic potion solution that is 30% DeMuggle Juice. He also has hundreds of 25 mL bottles that are full of
ELEN [110]

Answer:

8

Step-by-step explanation:

We use the equation for the percentage of solute concentration in a solution:

volume percent = \frac{volume of solute}{volume of solution} * 100   (1)

In this case the equiation (1) is transformed into:

34 = \frac{Total volume of DeMuggle juice}{Total volume of the magic potion} * 100   (2)

n = number of times he must waves his wand to have a solution that is at least 34% DeMuggle juice.

Vpo = Initial volume of the magic potion = 2000ml

Vjo= Initial volume of DeMuggle juice = 30% * Vpo = (0.3)2000 = 600ml

Vb= Volume of a bottle = 25ml

Vjb = DeMuggle juice volume in a bottle = 75% * Vb = (0.75)25= 18.75ml

Vpmt = Total volume of the magic potion = 2000 + 25*n = Vpo + Vb * n

Vjt = Total volume of DeMuggle juice = 600 + 18.75*n = Vjo + Vjb * n

Replacing in (2):

34 = \frac{600 + 18.75*n }{2000 + 25*n} *100

\frac{34}{100} (2000 + 25*n) = (600 + 18.75* n)

680+8.5*n=600+18.75*n

80 = 10.25*n

n = 7.8

Since the number of times the wand should be waved must be an integer, it approximates 8

Replacing n=8 in (1)

\frac{600+(18.75*8)}{2000+(25*8)} *100 = 34.0909
