4
44 trillion dollars.
If a one dollar bill is
0.0001
0.00010, point, 0001 meters thick, how many meters tall would a stack of
4
44 trillion one dollar bills be?
Write your answer in scientific notation.

Answer 1

Answer: To find the height of a stack of one dollar bills that equals 4/44 trillion dollars, we need to divide the total amount by the thickness of a single bill:

4/44 trillion dollars ÷ 0.0001 meters/bill = (4/44 trillion) / (0.0001) meters

Simplifying the fraction, we get:

(4/44 trillion) / (0.0001) meters = 0.0000000000045454545... meters

We can write this in scientific notation as:

4.5454545 × 10^-12 meters

So a stack of 4/44 trillion one dollar bills would be approximately 4.5454545 picometers tall.
