I'll guess the answer is <em>you can tell that pi is an irrational because it has a </em>non-terminating yet non-repeating decimal representation.<em> </em>

Of course it's not clear how we tell this. We can't know for sure just by looking at the first trillion digits we've figured out whether it repeats or not. Someone told us it didn't, that's really how we know.

A stick 43 inches long is broken into two pieces, so that one piece is twice as long as the other. How long are the two pieces?

allsm [11]

Answer:

One piece is $\frac{43}{3}$ inches and another piece is $\frac{86}{3}$ inches

Step-by-step explanation:

Let smaller piece length be $s$

Let larger piece length be $l$

Since total of two pieces is 43, we can write:

$s+l=43$

Also, one piece is twice as long as the other (so longer piece is definitely twice as the short piece), we can write:

$l=2s$

<em>Substituting equation 2 into equation one, we can solve for s:</em>

$s+l=43\\s+(2s)=43\\3s=43\\s=\frac{43}{3}$

<em>Thus longer piece is:</em>

$l=2s=2(\frac{43}{3})=\frac{86}{3}$

In the xy-plane, the equations x + 2 = 10 y and 3 +6 = x y c represent the same line for some constant c. What is the value of c

aalyn [17]

Answer:

C=30

Step-by-step explanation:

Supposing that we have the lines

x+2=10y

and

3x+6=Yc.

Note that dividing by 3 the second line can be rewritten as

x + 2= Y c/3.

Remember that a line is written as $ax+b=dY$ , in our case, both lines have $a=1$ and $b=2$ . Therefore, in orther that the two lines are equal, we need that $10=c/3$ , hence $c=30.$
