PLEASE HELP The ZIP code is a 5-digit number that is unique to a specific region of the country. If the digits 0-9 are used, how many ZIP codes are possible with 0 as the last digit? Note that, in this case, the first digit can't be 0.

90,000

18,000

10,000

9,000

9000

Step-by-step explanation:

The first digit can't be 0, so there are 9 numbers that can be used for the first digit.  The fifth digit must be 0, so there's only 1 number that can be used.  The other three digits can be any of 10 numbers.

So the number of zipcodes is:

9 × 10 × 10 × 10 × 1 = 9000

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
