Dafna11 [192]

Answer:

(a) $6550

(b) $1511.54

Step-by-step explanation:

(a) You can solve the equation

... 12 × (monthly salary) = $78,600

by dividing both sides of the equation by 12.

... (monthly salary) = $78,600/12 = $6,550

(b) You know there are 52 weeks in a year, so you know that ...

... 52 × (weekly salary) = $78,600

... (weekly salary) = $78,600/52 ≈ $1,511.54 . . . . . . . divide by 52

How many three-digit phone prefixes that are used to represent a particular geographic area are possible that have no 0 or 1 in
Sonbull [250]

Answer:

The number of possible three-digit phone prefixes that are used to represent a particular geographic area is 640.

Step-by-step explanation:

The phone prefixes used to represent a particular geographic area are a 3 digit code consisting of numbers from 0 to 9.

The prefix code are of the form: <u>x</u> <u>x</u> <u>x</u>

Condition: The first or the second place cannot take values 0 or 1.

Then the first place can be occupied by the remaining 8 digits.

Similarly the second place can also be occupied by the remaining 8 digits.

And the third place can be occupied by any of the 10 digits.

So the number of ways to construct a phone prefix for any area is:

Possible\ number\ of\ phone\ prefixes=8\times8\times10=640

Thus, the number of phone prefixes possible for any area is 640.
