22.4
= 22 + 4/10
-------------------------
Or:
22.4
= 224/10
= 112/5
Answer:
I'm pretty sure they either terminate after so many digits (end) or repeat a certain pattern of numbers.
Step-by-step explanation:
The first will look like this: 432.2340
The second would look like this: 324.234234234... ("234" would keep repeating over and over and over. And can be any sequence of #'s)

I think I know how to do it
Your equation is:
P₁V₁ = P₂V₂
You Know:
Initial:
P₁ = 84 Pa
V₁ = 336 L
New:
P₂ = ?
V₂ = 216L
Plug this into the equation:
P₁V₁ = P₂V₂
(84 Pa)(336 L) = P₂(216 L) Divide 216 on both sides

130.6666666 = P₂
(if your doing significant figures, you have 2 sig figs)
130 Pa = P₂
1. BC is 1+3=4 (units)
2. AD is 3+5= 8 (units)
3. Draw the altitude CH from point C, as shown in the figure.
4. Then triangle CHD is a right triangle, with hypothenuse CD, and sides HD and CH.
5.



6. AB=CD=4.47 because the trapezoid is isosceles.
7. P= BC+AD+AB+CD=4+8+4.47+4.47=20.9 (units)
