What is that A
What is that
All the numbers listed are rational, since they can all be represented as a fraction, EXCEPT "2 in the house thingy", which I suppose is

.
This last one is irrational, because it cannot be represented as a finite fraction.
The following is a check to make sure:
1/3 is already a fraction
2/7 is already a fraction
2 in the house thingy =

cannot be converted into a finite fraction.
3.624 = 3624/1000 is a fraction
0.6 repeat = 2/3 is a fraction
0.87 repeat = 87/99 = 29/33 is a fraction
-5 = -5/1 is a fraction.
3 (m + 5 + 9m)
Two expressions that are e<span>quivalent to the given expression are:
3m + 15 + 27m
or
30m + 15
you get both expressions by multiplying the original expression
the second expression is obtained by adding the like terms</span>
We are looking for the amount of wax it will take to fill up that size candle mold to make that candle. That means that we are looking for the volume of wax, and the shape is a cylinder. The volume formula for a cylinder is
.
For us, that will look like this:
which translates to
V = 3.14(9)(5) which gives us a volume of 141.3 cubic inches. Rounding to the nearest cubic inch is simply 141 cubic inches of wax.
