That would be one hard code to guess. The answer is simple but the number is actually. So how many letters and numbers are there?

Well, 26 letters, and we have 10 numbers including zero. I will give you two answers.

Assuming we can repeat characters i.e. we can have T56DDD,

then each slot has 36 options to choose from.

Total combinations in that case is 36^6.
(Basically 36*36*36*36*36*36)

If we cannot repeat and each character has to be unique e.g. UNIQUE

then the first slot has 36 options. It can use any character.

The second slot can use any character except the first. Thus 35 options etc.

Total combinations = 36*35*34*33*32*31

What is 2 2/5×2 7/9 in simplest mixed number form?
Scorpion4ik [409]

Answer:

6 2/3

Step-by-step explanation:

2 2/5 * 2 7/9

Change each number to an improper fraction

2 2/5 = (5*2+2)/5 = 12/5

2 7/9 = (9*2+7) = 25/9

12/5 * 25/9

Rewriting

25/5  * 12/9

5/1 * 4/3

20/3

Now changing to a mixed number

3 goes into 20 6 times with 2 left over

6 2/3

OlgaM077 [116]
By definition the area of a rectangle is:
 A = l * w
 Where,
 l: long
 w: width
 So we have to clear the width:
 w = A / l
 Substituting the values:
 w = (234) / (18) = 13
 w = 13 feets
 answer
 the width, in feet, of the room is 13

Use Euler’s Formula to find the missing number.<br> Edges: 37<br> Faces: 25<br> Vertices: ?
matrenka [14]

Answer:

Step-by-step explanation:

Comment

The formula that relates edges faces and vertices is  F + V = E + 2

Givens

Edges (E): 37

Faces (F) = 25

Vertices: x

Solution

25 + x = 37 + 2                Subtract 25 from both sides.

25-25 +x= 37 - 25 + 2    Combine

x = 12 + 2

x = 14

Answer: The vertices =<u> 14</u>
