A bank requires that its customers create a PIN to access their account. The PIN must be 1 letter followed by 3 numbers. How many unique PINs are there?

26,000

Step-by-step explanation:

There are 4 places to be filled.

_ _ _ _

Now we put in each place the number of possible characters that can go there.

26 10 10 10

Finally we multiply all the numbers together.

26 * 10 * 10 * 10 = 26,000

26,000

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
