a tape dispenser holds 1.14 x 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.

a 1.4478 x 10^5 mm^2
b 14.478 x 10^4 mm^2
c 14.478 x 10^5 mm^2
d 1.4478 x 10^4 mm^2

To find the total area of tape, we need to multiply the length (1.14 x 10^4 mm) by the width (12.7 mm).

1.14 x 10^4 mm * 12.7 mm = 14.478 x 10^4 mm^2

Therefore, the answer is option b: 14.478 x 10^4 mm^2.

To find the total area in square millimeters of tape, we need to multiply the length and the width of the tape.

Length of tape = 1.14 x 10^4 mm
Width of tape = 12.7 mm

To find the total area, we multiply the two numbers:

Area = Length × Width
Area = (1.14 x 10^4 mm) × (12.7 mm)

To multiply these numbers, we multiply the coefficients and add the exponents:

Area = (1.14 × 12.7) × 10^(4 + 0)
Area = 14.478 × 10^4

In scientific notation, this is written as:

b) 14.478 x 10^4 mm^2

To find the total area in square millimeters of tape, you need to multiply the length of the tape by its width.

Given that the tape dispenser holds 1.14 x 10^4 mm of tape and the tape is 12.7 mm wide, you can multiply these two numbers to find the product.

1.14 x 10^4 mm * 12.7 mm = 14,478 mm^2

To express this answer in scientific notation, you need to write it as a number between 1 and 10, multiplied by a power of 10. In this case, the number is 1.4478, and the power of 10 is 10^4.

Therefore, the answer in scientific notation is:

d) 1.4478 x 10^4 mm^2
