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

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:

Thus, the number of phone prefixes possible for any area is 640.
It looks a little less than 1/2 or 4/8, so probably 3/8 of the gas is left.
