GIVEN: Tiffany is packing her bags for her vacation. She has $8$ unique toy animals, but only $4$ fit in her bag.

TO FIND: How many different groups of $4$ toy animals can she take.

SOLUTION:

Total unique toy animal Tiffany has $=8$

Total animal that fit in her bag $=4$

Now,

Tiffany has to select $4$ toy animals from $8$ animals.

Number of ways of selecting 4 toy animals $=^8C_4$

$=\frac{8!}{4!4!}$

$=70$

Hence Tiffany has 70 different ways to select group of 4 unique toys.

atroni [7]

Answer:

10 feet

Step-by-step explanation:

Drawing obviously not to scale but... Red segment is the ruler, at least the part between 5 and 6 inches, 1 inch long. Brown segment is the pole, ground to the top. Leftmost point is the eye, green line is the horizontal. The triangles are similar (AAA, the vertical lines are parallel), the ratio of the side is the same as the ratio of the heights. The height of the larger triangle (measured across the green line is

$40 yd \times 3\frac{ft}{yd} \times 12\frac{in}{ft}= 1440''$ .

Ratio of the height is then $1440\div24 = 60$ .

At this point the height of the pole is 60 times the length of the measure on the ruler, or 60 inches, that is 5 feet. Add the 5 feet the pole was starting from, it's 10 feet.
