Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
![## How Much Larger is Russia Compared to Jamaica?
The area of Russia is about \( 1.71 \times 10^7 \) square kilometers. The area of Jamaica is about \( 1.10 \times 10^4 \) square miles. To determine how many times larger Russia is compared to Jamaica, we will perform a division using scientific notation and round the decimal part of the answer to two decimal places.
### Calculation Steps:
1. **Division in Scientific Notation:**
\[ \frac{1.71 \times 10^7}{1.10 \times 10^4} \]
2. **Simplify the Expression:**
\[ \frac{1.71}{1.10} \times 10^{7-4} = 1.554545 \times 10^3 \]
3. **Rounding to Two Decimal Places:**
\[ 1.554545 \approx 1.55 \]
Thus, the result is:
\[ 1.55 \times 10^3 \]
### Answer Choices:
a. Russia is about \( 1.55 \times 10^2 \) times larger than Jamaica.
b. Russia is about \( 1.55 \times 10^3 \) times larger than Jamaica.
c. Russia is about \( 1.55 \times 10^4 \) times larger than Jamaica.
d. Russia is about \( 1.55 \times 10^1 \) times larger than Jamaica.
### Correct Answer:
The correct answer is:
\[ \boxed{\text{B}} \]
Russia is about \( 1.55 \times 10^3 \) times larger than Jamaica.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5cdb4ceb-5725-4e11-93d9-ff0a52d1e35d%2F9dd8da12-e72b-4e08-b005-66fc36a5d492%2Ffevprgq_processed.jpeg&w=3840&q=75)
