A number equivalent to 63.24

182 divided by 7= 26

the old virus program scanned at 26 megabytes per second

35-26= 9

the new anti-virus program is 9megabytes per second faster than the old program

(if looking for percentage increase/decrease read on)

formula=new subtract old divided by old times 100

((35-26) divided by 26)(100)

(9 divided by 26)(100)

0.34615(100)

34.62% increase

the new virus program is 34.62% faster than the old one

Answer:

40 games

Step-by-step explanation:

We can use ratios to solve

8 passes        x passes

--------------- = -----------

3 games         15 games

Using cross products

8 * 15 = 3 *x

120 = 3x

Divide each side by 3

120/3 = 3x/3

40 = x

Answer:

Answer:

Amy can choose from 60 possible passwords.

Solution:

Given that the two-letter password is from the letters A, B, C, D, E and F

Total number of letters = 6  

The password is a two digit letter and repetition of letters is not allowed.

Method 1:

\therefore The number of ways of obtaining an ordered subset of r elements from a set of n elements is given by

So, the total possible password = = =

On cancelling the in numerator and denominator we get,

Here we get, = 30  possible passwords

Method 2:

There are 6 possible choices for the first term of the password and 5 choices for the second term (i.e. leaving the selected letter of the term)

So,

Answer:

30

Step-by-step explanation:

6 choices for the 1st, then 5 choices for the 2nd, so: 6*5=30

or  nPk=n!/(n-k)!  with n=6 and k=2

Put it simply each letter can be combined with 5 diffrent letters and with 6 total letters 6x5=30
