Possible procedures:

1). peanut, peanut
2). peanut, cashew
3). peanut, pecan
4). cashew, peanut
5). cashew, cashew
6). cashew, pecan
7). pecan, peanut
8). pecan, cashew
9). pecan, pecan.

Nine (9) possible procedures.
But ...
(2) and (4) produce the same final result.
(3) and (7) produce the same final result.
(6) and (8) produce the same final result.

So there are only six (6) possible different outcomes.

What is the length of AC¯¯¯¯¯ ?

Harman [31]

Answer:

AC = 12.38 cm

Step-by-step explanation:

When there are 2 pairs given, we can use the sine rule to solve the problem.

By pairs we mean "an angle and side opposite to it"

1 pair is 85.2 degree angle and 13 cm, and another pair is 71.6 degree angle and the side AC (which we want to figure out).

Sine Rule is given by $\frac{SinA}{a}=\frac{SinB}{b}$

where,

A and B are the two respective angles and a and b are the two respective sides (of the pairs). Plugging all the info and using algebra, we have:

$\frac{Sin85.2}{13}=\frac{Sin71.6}{AC}\\AC*Sin85.2=13*Sin71.6\\AC=\frac{13*Sin71.6}{Sin85.2}\\AC=12.38$

Thus, AC = 12.38 cm

Leviafan [203]

X- the total number of families in Smithville.
(2/3)x - the number of home owning families.
At the same time, the number of home owning families is 480.

(2/3)x=480
x=480*3/2=720.

720 families live in Smithville.
