I m getting 308.11, there is an additional 0.60 that is added, maybe your source is wrong, or there is a copying error.
Answer:
Explanation:
Number the sides of the decagon: 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10, from top (currently red) clockwise.
- The side number one can be colored of five different colors (red, orange, blue, green, or yellow): 5
- The side number two can be colored with four different colors: 4
- The side number three can be colored with three different colors: 3
- The side number four can be colored with two different colors: 2
- The side number five can be colored with the only color left: 1
- Each of the sides six through ten can be colored with one color, the same as its opposite side: 1
Thus, by the multiplication or fundamental principle of counting, the number of different ways to color the decagon will be:
- 5 × 4 × 3 × 2 ×1 × 1 × 1 × 1 × 1 × 1 = 120.
Notice that numbering the sides starting from other than the top side is a rotation of the decagon, which would lead to identical coloring decagons, not adding a new way to the number of ways to color the sides of the figure.
Since .7 is above 5.
$45.71 would turn to $46.00.
You would round 45... the 5 to 6...
To be $46
Answer: 45
Step-by-step explanation:
60 x .75. = 45
No you aren't, just add the like terms! Meaning, add the terms with y and and the terms without y. You will get 4y+29
