Th total possible outcomes are 6^3 = 216

The possible ways of getting 15 are 
555
456
465
546
564
645
654
366
663
636

Jordan is putting a fence around a garden that is shaped like a half circle and rectangle
grin007 [14]

Answer:

92 ft  

Step-by-step explanation:

Assume the garden has the shape shown below.

The length of fencing equals the distance around three sides of the rectangle plus that around the semicircle.

1. Around the rectangle

Distance = 28 ft + 14 ft + 28 ft = 70 ft

2. Around the semicircle

For a circle.

C = 2πr

For the semicircle,

½C =½(2πr) = πr  

D = 14 ft, so

r =    7 ft

\text{Distance} = \dfrac{22}{7} \times \text{7 ft} = \text{22 ft}

3. Total distance

Distance = 70 ft + 22 ft = 92 ft

Jordan will need 92 ft of fencing.

Andrews [41]

Answer:

Permutation

504 ways

Step-by-step explanation:

The difference between combinations and permutations is ordering. With permutations we DO care about the order of the elements, whereas with combinations we don't.

In your graphing calculator, type

nPr(9,3)

(9 letters in trapezoid, 3 letter combos)

and it returns 504.
