Q. A typical business card is 0.0130.013 inches thick. How would you write the approximate thickness in scientific notation?\newlineChoices:\newline(A) 1×1021 \times 10^2 inches\newline(B) 1×10−21 \times 10^{-2} inches\newline(C) 1×1031 \times 10^3 inches\newline(D) 1×10−31 \times 10^{-3} inches
  1. Convert to Scientific Notation: Convert the thickness of the business card to scientific notation by identifying the decimal place to create a number between 11 and 1010.$0.013\$0.013 inches = 1.3×10−21.3 \times 10^{-2} inches).
  2. Choose Correct Answer: Choose the correct answer from the given choices that matches the scientific notation.\newline1.3×10−21.3 \times 10^{-2} inches is approximately 1×10−21 \times 10^{-2} inches, so the correct choice is (B)1×10−21 \times 10^{-2} inches.
