What is the slope of a line perpendicular to the line whose equation is 3x-7y+14=0?

1 answer:

7 0

1. Find the slope of the given line. Do this by solving <span>3x-7y+14=0 for m:

3x + 14 = 7y, which gives us m = 3/7.

2. Find the slope of a line perpendicular to this one. It's the negative reciprocal of m = 3/7, or -7/3.

To negatives equal a positive. Convert both of the mixed numbers into a improper fraction. Cross simplify 5 and 5, they both turn into one’s. Multiply and you should get 7/3 or 2 1/3.

He didn’t multiply the equation by 1/2 in the second part so it threw his whole answer off. Hope this helps

How many milliequivalents of sodium chloride are contained with 3 L of normal saline?

AVprozaik [17]

Answer:

466mEq

Step-by-step explanation:

First, we need to know the concentration of NaCl in a normal saline solution, this is by definition 0.9%, meaning we have 0.9g of NaCl per 100ml of solution, we want to know how much NaCl we have in 3L (3000ml):

$3000ml*\frac{0.9g}{100ml}=27g=27000mg$

So, we have 27000mg in 3L of normal saline solution.

Now, acording to our milliequivalent (mEq) equation ( $mEq=\frac{mg}{pE}$ ) where pE is de molecular mass of NaCl divided by their charges, in this case 1:
