Answer:
540 degrees in a pentagon
4 + 8 + 6 + 4 + 5 = 27
540/27 = 20
4 X 20 = 80 degrees
8 X 20 = 160 degrees
6 X 20 = 120 degrees
4 X 20 = 80 degrees
5 X 20 = 100 degrees
Answer:
20.22 miles
Step-by-step explanation:
If 10 laps is 6.74 then 30 laps is 3*6.74 which is 20.22
If the blocks were 9 different colors, then there would be
9 !(factorial) = 362,880 different ways to line them up.
But for each different line-up, there are 5! =120 ways to arrange
the green blocks and you can't tell these apart, 2!= 2 ways to arrange
the white blocks and you can't tell these apart, and 2!=2 ways to arrange
the orange blocks and you can't tell these apart.
So the number of distinct, recognizable ways to arrange all 9 blocks
is
(9!) / (5! · 2! · 2!) = (362,880) / (120 · 2 · 2) = 756 ways.
The answer would be 4.5 pounds of salt.
