A right triangle has side lengths 12 centimeters and 14 centimeters. Name two possible side lengths for the third side, and expl
madam [21]

Answer:

If 12 and 14 are both side lengths then we solve for the hypotenuse:

hypotenuse^2 = 12^2 + 14^2

hypotenuse^2 = 144 + 196

hypotenuse^2 = 340

hypotenuse = sq root (340) = 18.4390889146

If hypotenuse = 14, then third side equals:

(3rd side)^2 = 14^2 - 12^2

(3rd side)^2 = 196 -144

(3rd side)^2 = 52

3rd side = sq root (52) = 7.2111025509

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:

pE= \frac{23+35}{1}=\frac{58}{1} = 58

Finally we substitute in the mEq formula:

mEq=\frac{mg}{pE}=\frac{27000}{58}=466mEq

I hope you find this information useful! Good luck!

Consider the triangle below. Determine the angle measure for the bottom two angles in order for the triangle to be classified as
FinnZ [79.3K]
Answer:

The angle measure for the bottom two angles in order for the triangle to be classified as an isosceles triangle are 30 degrees each

Explanation:

An isosceles triangle has two of its angles equal.

Given that one angle is 120 degrees, assuming the remaining angles are equal, since the sum of the angles in a triangle is 180 degrees, we have:

120 + x + x = 180

120 + 2x = 180

2x = 180 - 120 = 60

x = 60/2 = 30

Each of the remaining angles measure 30 degrees
