in a given year, about 1.52\times 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 find the total cost to deliver all the pieces of mail, we multiply the number of pieces of mail by the cost of each stamp.
Number of pieces of mail = 1.52 × 10^10
Cost of each stamp = $0.55
Total cost = (1.52 × 10^10) × ($0.55)
To multiply numbers in scientific notation, we multiply the coefficients and add the exponents.
Total cost = 1.52 × 0.55 × 10^10
To calculate the product of 1.52 and 0.55, we multiply the decimals.
Total cost = 0.836 × 10^10
Therefore, the total cost to deliver all the pieces of mail is 8.36 × 10^9 dollars.
To find the total cost, we can multiply the number of pieces of mail by the cost of each stamp.
Number of pieces of mail = 1.52 x 10^(10)
Cost of each stamp = $0.55
Total cost = 1.52 x 10^(10) * $0.55
To multiply these numbers, we multiply the coefficients and add the exponents of 10:
1.52 x 0.55 x 10^(10)
Multiplying the coefficients gives us:
0.836
And adding the exponents gives us:
10^(10)
Therefore, the total cost in dollars to deliver all the pieces is:
0.836 x 10^(10) or 8.36 x 10^(9)
To find the total cost in dollars to deliver all the pieces of mail, we need to multiply the number of pieces by the cost of each stamp.
The number of pieces of mail is given as 1.52 × 10^10.
The cost of each stamp is $0.55.
To find the total cost, we can set up the following equation:
Total cost = Number of pieces × Cost of each stamp
Total cost = (1.52 × 10^10) × ($0.55)
To multiply these numbers, we can multiply the numerical parts and add the exponents:
Total cost = 1.52 × 0.55 × 10^10
Calculating this, we get:
Total cost = 0.836 × 10^10
Since the result is already in scientific notation, expressed to the exact decimal place, the total cost to deliver all the pieces is 0.836 × 10^10 dollars.
