In a given year, about 1.52×1010 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)
I apologize for the mistake. Let's correct the calculation.
The total cost to deliver all the pieces of first-class mail can be calculated by multiplying the number of pieces by the cost of each stamp.
1.52 × 10^10 pieces x $0.55/stamp = $8.36 × 10^9.
Therefore, the total cost in dollars to deliver all the pieces is 8.36 × 10^9 dollars.
The total cost to deliver all the pieces of first-class mail can be calculated by multiplying the number of pieces by the cost of each stamp.
52×1010 pieces x $0.55/stamp = $8.36×1010
In scientific notation, this is expressed as 8.36x1010 dollars.
thats wrong
To find the total cost in dollars to deliver all the pieces of mail, we can multiply the number of pieces of mail by the cost of a stamp.
Number of pieces of mail = 1.52×10^10
Cost of a stamp = $0.55
Total cost = (Number of pieces of mail) x (Cost of a stamp)
Total cost = 1.52×10^10 x $0.55
Let's calculate the result:
Total cost = 1.52×10^10 x $0.55 = $8.36×10^9
Therefore, the total cost in dollars to deliver all the pieces is $8.36x10^9.
To find the total cost to deliver all the pieces of first-class mail in the U.S., you can multiply the number of pieces of mail by the cost of a stamp for each piece. Let's go step by step.
Step 1: Convert the given number, 1.52×10^10, to standard decimal form:
1.52×10^10 = 1.52 * 10,000,000,000 = 15,200,000,000
Step 2: Multiply the number of pieces of mail (15,200,000,000) by the cost of a stamp ($0.55):
15,200,000,000 * $0.55 = $8,360,000,000
Step 3: Convert the result, $8,360,000,000, to scientific notation:
$8,360,000,000 = 8.36 * 1,000,000,000 = 8.36×10^9
Therefore, the total cost to deliver all the pieces of first-class mail in the U.S. is $8.36×10^9 in scientific notation.
