A tape dispenser holds 1.14×104 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 tape in square millimeters, we need to multiply the length by the width.
The length of tape is given as 1.14×10^4 mm and the width is 12.7 mm.
Multiplying these two numbers gives:
1.14×10^4 mm * 12.7 mm = 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 tape, you need to multiply the length (1.14×10^4 mm) by the width (12.7 mm).
1.14×10^4 mm * 12.7 mm = 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 and the width of the tape.
The length of the tape is given as 1.14×10^4 mm.
The width of the tape is given as 12.7 mm.
To find the total area, you multiply these two quantities:
1.14×10^4 mm × 12.7 mm
When multiplying numbers in scientific notation, you simply multiply the coefficients (the numbers in front) and add the exponents (the powers of 10).
1.14 × 12.7 = 14.478
10^4 × 10^0 = 10^4 (since any number raised to the zero power is 1)
Therefore, the total area in square millimeters of the tape is 14.478 × 10^4 mm^2.
So, the correct answer is option C. 14.478×10^4 mm^2.
