Answer:

x=6

Step-by-step explanation:

x is a variable, meaning it represents an unknown value.

To solve equations, you need to solve for x.

The first step is isolating x.

To isolate x, get it alone.

Start by subtracting 2 from <u>both</u> sides.

x = 6

There is your answer.

Answer:

Subtract two from 8, the remainder is x. In this case, it is 6.

For future questions, try to think of x as a mystery number rather than a letter. You got this. :)

For this case we can apply the Pythagorean theorem to find "x". Taking the rectangle triangle of base 5 we have:

x = \sqrt {11 ^ 2-5 ^ 2}\\x = \sqrt {121-25}\\x = \sqrt {96}\\\x = \sqrt {4 ^ 2 * 6}

By definition of power properties we have:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

So:

x = 4 \sqrt {6}

Answer:

x = 4 \sqrt {6}

Calculate the amount of hcn that gives the lethal dose in a small laboratory room measuring 12.0 ft×15.0 ft×8.50ft.
Anarel [89]
Dimensions of the room in cm = 2.54 x 12 by 15 x 2.54 by 2.54 x 8.5 = 30.48 by 38.1 by 21.59

Volume of the room in cubic cm = 30.48 x 38.1 x 21.59 cubic cm = 25,072.21 cubic cm

Given that the density of air at room temperature is 0.00118g/cm^3, thus the mass of air in the room = 25,072.21 x 0.00118 = 29.59 g = 0.0296 kg

Given that the lethal dose of HCN is approximately 300 mg HCN per kilogram of air when inhaled, thus the <span>amount of HCN that gives the lethal dose in the small laboratory room is given by 300 x 0.0296 = 8.88 mg.</span>
