In a given year, about 1.52×10^10 pieces of first-class mail are delivered in the U.S. If each piece of mail carries a stamp costing $0.55, what is the total cost in dollars to deliver all the pieces? Write the answer in scientific notation, expressed to the exact decimal place.(1 point)
To calculate the total cost to deliver all the pieces of first-class mail, we need to multiply the number of pieces by the cost of each stamp.
Number of pieces of first-class mail = 1.52×10^10
Cost of each stamp = $0.55
To find the total cost, we'll multiply these two numbers:
Total cost = (1.52×10^10) * ($0.55)
To multiply the numbers in scientific notation, we multiply the coefficients and add the exponents:
Total cost = 1.52 * 0.55 * 10^(10+0)
Multiplying the coefficients gives:
Total cost = 0.836 * 10^(10+0)
Adding the exponents gives us:
Total cost = 0.836 * 10^10
If we express this in scientific notation with the exact decimal place, we get:
Total cost = 8.36×10^9 dollars
To find the total cost to deliver all the pieces of mail, we can multiply the number of pieces by the cost of each stamp:
1.52×10^10 * $0.55 = 8.36×10^9
So the total cost to deliver all the pieces is $8.36×10^9.
To find the total cost in dollars to deliver all the pieces of mail, we need to multiply the number of pieces of mail by the cost of each stamp.
Given that there are 1.52×10^10 pieces of mail and each stamp costs $0.55, we can calculate the total cost by multiplying the two values together.
1.52×10^10 * $0.55
To multiply two numbers in scientific notation, we multiply the numerical parts and add the exponents.
1.52 * 0.55 = 0.836
10^10 * $0.55 = $55000000000
So, the total cost to deliver all the pieces of mail is $55000000000.
Expressing this answer in scientific notation, we have 5.5×10^10 dollars.
