Answer:
0.761
Step-by-step explanation:the 7 is in the tenths the 6 is in the hundredths and the 1 is in the thousandths
Given:
The given digits are 1,2,3,4,5, and 6.
To find:
The number of 5-digit even numbers that can be formed by using the given digits (if repetition is allowed).
Solution:
To form an even number, we need multiples of 2 at ones place.
In the given digits 2,4,6 are even number. So, the possible ways for the ones place is 3.
We have six given digits and repetition is allowed. So, the number of possible ways for each of the remaining four places is 6.
Total number of ways to form a 5 digit even number is:
![Total=6\times 6\times 6\times 6\times 3](https://tex.z-dn.net/?f=Total%3D6%5Ctimes%206%5Ctimes%206%5Ctimes%206%5Ctimes%203)
![Total=3888](https://tex.z-dn.net/?f=Total%3D3888)
Therefore, total 3888 five-digit even numbers can be formed by using the given digits if repetition is allowed.
Answer:
1.36 centimeters
Step-by-step explanation:
Given,
side length ( a ) = 17 mm
To find : Perimeter of regular octagon ( in cm )
Octagon has 8 sides.
Perimeter of regular octagon
= 8 x a
= 8 x 17
= 136 mm
1 mm = 0.1 cm
136 mm
= 136 x 0.1
= 1.36 centimeters ( cm )
Hence,
Perimeter of regular octagon is 1.36 centimeters.

We know how much 16 keychains is, now we need to find how much one is.
19.68 / 16 = $1.23
$1.23 is the price of one keychain, now you can multiply that by 25 to see how much 25 keychains cost.
