A certain organization recommends the use of passwords with the following format: vowel commavowel, consonant comma consonant c

zimovet [89]

The password format is = inpray93

vowel , consonant, consonant, consonant, vowel, consonant, number, number.

There are 21 consonants, 5 vowels and 10 number choices (0-9)

Since, there are 21 consonants and repetition is allowed so for 2nd, 3rd, 4th, and 6th positions 21 choices are available. For 1st and 5th positions, 5 choices are available and for 7th and 8th position there are 10 choices (0 to 9).

Passwords are not case sensitive which means upper case and lower case letters are same.

So, the number of passwords can be =

$5\times21\times21\times21\times5\times21\times10\times10$

= 486202500

Part (b) question is not given. But it can be opposite to the first part i.e when the password letters are case sensitive.

This means all the letters are different.

So, number of passwords will be =

$10\times42\times42\times42\times10\times42\times10\times10$

= 31116960000

What is 6 divided by a number that will give you 12

AURORKA [14]

▶︎◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◀︎

$Hello$ $There!$

We need to find what number, if 6 is divided by it, gives us 12.

This isn't hard, I promise! I am going to take you through a few steps, and we'll find the answer.

Are you ready? Then let's begin...:)

$Procedure:$

✦ We can think about it as: 6 divided by what number gives us 12?

(let the number be z)

$^6/_z=12$

Multiply both sides by z

$6=12z$

Divide both sides by z

$z=^6/_{12}$

Which is the same as

$z=^1/_2$

hope it's helpful!
wishing you a great day!

$Greetings!$

choli [55]

Answer:

Here is the way to get the answer

Step-by-step explanation:We use the formule: t=S/v. So:

+ t1= 160/100 = 8/5 hrs = 5760''

+ t2= 160/90 = 16/9 hrs = 6400''

=> t2-t1= 6400 - 5760 = 640'' = 10'40''
