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. Responses 14.478×104 mm2 14.478 times 10 superscript 4 baseline mm squared 1.4478×105 mm2 1.4478 times 10 superscript 5 baseline mm squared 14.478×105 mm2 14.478 times 10 superscript 5 baseline mm squared 1.4478×104 mm2
To find the total area in square millimeters of the tape, you need to multiply the length and width.
1.14×10^4 mm × 12.7 mm = 14.478×10^4 mm^2
So, the product in scientific notation is 14.478×10^4 mm^2.
To multiply numbers in scientific notation, you multiply the coefficients and add the exponents.
In this case, the coefficient is obtained by multiplying 5.5 and 2.2, giving 12.1. The exponents are obtained by adding 4 and -8, resulting in -4.
Therefore, the answer, in scientific notation, is 1.21×10^(-4).
To find the product of two numbers in scientific notation, you need to multiply their coefficients and add their exponents.
In this case, multiply the coefficients: 5.5 × 2.2 = 12.1.
Next, add the exponents: 10^4 × 10^(-8) = 10^(4 + -8) = 10^(-4).
Therefore, the answer is 12.1 × 10^(-4).
