HELP!You are handed a 8.0 cm stack of new one-dollar bills. Assume the thickness of a dollar bill is 1.4 times thicker than your textbook paper (textbook paper = 63 um). (that's "micrometers") How many dollars are in your stack?
To find the number of dollars in a stack, we need to divide the total thickness of the stack by the thickness of a single bill.
First, let's convert the thickness of your textbook paper to centimeters:
63 um = 63 * 0.0001 cm = 0.0063 cm
Given that the thickness of a dollar bill is 1.4 times thicker than your textbook paper, we can calculate the thickness of a dollar bill:
Thickness of a dollar bill = 1.4 * 0.0063 cm = 0.00882 cm
Now, we can calculate the number of dollars in the stack:
Number of dollars = Total thickness of stack / Thickness of a dollar bill
Total thickness of stack = 8.0 cm
Number of dollars = 8.0 cm / 0.00882 cm ≈ 907.26
Therefore, there are approximately 907 one-dollar bills in the stack.
To find out the number of dollars in your stack, you need to calculate the total thickness of the stack and then divide it by the thickness of a single dollar bill.
Let's begin by converting the thickness of your textbook paper to centimeters:
63 μm = 63 × 10^(-4) cm = 0.0063 cm
Now, let's calculate the thickness of a single dollar bill:
Thickness of dollar bill = 1.4 × 0.0063 cm
Thickness of dollar bill = 0.00882 cm
Next, we need to determine the number of dollar bills in the 8.0 cm stack:
Number of dollar bills = Total thickness of stack / Thickness of each bill
Number of dollar bills = 8.0 cm / 0.00882 cm
Number of dollar bills = 906.57
Since you cannot have a fraction of a dollar bill, we will round down to the nearest whole number.
Therefore, there are 906 dollar bills in your stack.
thickness of dollar bill=(63E-6)*1.5m
numberbills=stackheight/thickeness one
= .08m/(1.5*63E-6)m= you do it. I get less than 900
