A tape dispenser holds 1.14×10^4 mm of tape that is 12.7 mm wide. Multiply the two numbers to find the total area in square millimeters of tape. Write the product in scientific notation.(1 point)
A. 1.4478×10^5 mm^2
B. 14.478×10^5 mm^2
C. 14.478×10^4 mm^2
D. 1.4478×10^4 mm^2
To find the total area of the tape, we need to multiply the length of the tape (1.14×10^4 mm) by the width of the tape (12.7 mm).
1.14×10^4 mm * 12.7 mm = 14.478×10^4 mm^2
This can be written in scientific notation as 1.4478×10^5 mm^2.
Therefore, the correct answer is A. 1.4478×10^5 mm^2.
To find the total area in square millimeters of the tape, you need to multiply the length of the tape (1.14×10^4 mm) by the width of the tape (12.7 mm).
1.14×10^4 mm * 12.7 mm = 1.4478×10^5 mm^2
So the answer is A. 1.4478×10^5 mm^2.
To find the total area of tape in square millimeters, we need to multiply the length of the tape by its width.
The length of the tape is given as 1.14×10^4 mm, and the width is given as 12.7 mm.
To multiply these two numbers, we multiply the coefficients (1.14 and 12.7) and add the exponents of 10 (4 and 0) to get the final answer.
1.14 × 12.7 = 14.478
10^4 × 10^0 = 10^4
Therefore, the product in scientific notation is 14.478×10^4 mm^2.
So, the correct answer is option C. 14.478×10^4 mm^2.
