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

Sophia is saving money for a new bicycle. The bicycle will cost at least $623. Sophia makes $8.22 per hour. Which inequality cou

tankabanditka [31]

<span>$8.22h â‰Ą $623 Let's look at the options and see what works and what doesn't. $8.22h > $623 * This inequality mostly works and it's true. But there may be a better choice later. So let's hold off on this one. $8.22h â‰¤ $623 * That less than or equal has issues. Let's buy the bike if I have less money than what's needed? Nope, not gonna work. Although that equal portion does have an element of truth to it. But this is a bad choice. $8.22h â‰Ą $623 * And this third option is better than the first. It simply says that you have to have enough or more money to buy the bike. The 1st equation basically said you have to have more money than the cost of the bike. So this is the correct choice. $8.22h < $623 * This is worse than the 2nd option. In a nutshell, is says buy the bike when you don't have enough money. So bad choice.</span>

Aisha is going to ship some gifts to family members, and she is considering two shipping companies. The first shipping company c

olasank [31]

Answer Step-by-step explanation:

Word (story) problems are easy if you use a table to translate the words to precise, concise math variables and operations. For example,

Is means =

Larger than +

Four times a 4*a

F is 550 less than S F = S – 550

Total of A, B, C A + B + C

This seems obvious – until you get stuck on a word problem. So,

“the first company” , “a second company” becomes Let their costs be F and S

Let K be the number of kilograms

“$20 to ship a medium box, plus an additional $2 per kilogram” F = $20 + 2*K

“10 for the same size of box, plus an additional $3 per kilogram” S = $10 + 3*K

“the two shipping methods will cost the same amount” F = S

“What is that weight?” report K

Now, the math:

F = S

20 + 2K = 10 + 3K

$10 = K
