How many centimeters are in 1.23×10−6 kilometers?
- A.
0.123 cm
- B.
0.1234 cm
- C.
0.12 cm
- D.
0.13 cm
Correct Answer
A. 0.123 cmExplanation
To convert kilometers to centimeters, you need to use the conversion factors: 1 kilometer = 1,000 meters and 1 meter = 100 centimeters.
So, to find out how many centimeters are in 1.23 x 10^-6 kilometers: 1.23 x 10^-6 km x 1,000 meters/km x 100 centimeters/meter = 1.23 x 10^-6 x 100,000 = 0.123 centimeters.
So, the answer is 0.123 centimeters.Rate this question:

Approximately how many hours are there in 34.5 years?
- A.
302,000 hrs
- B.
302,220 hrs
- C.
0.00394 hrs
- D.
0.00393835 hrs
Correct Answer
B. 302,220 hrsExplanation
To calculate the number of hours in 34.5 years, you can use the following calculation:
Number of hours in a year × Number of years
There are typically 365 days in a year, and each day has 24 hours. So, in a non-leap year:
365 days/year × 24 hours/day = 8,760 hours/year
Now, you can multiply this by the number of years:
8,760 hours/year × 34.5 years = 302,220 hours
So, there are approximately 302,220 hours in 34.5 years.Rate this question:

How many inches are there in 355 millimeters?
- A.
13.97 inches
- B.
14.90 inches
- C.
140.0 inches
- D.
139.0 inches
Correct Answer
A. 13.97 inchesExplanation
To convert millimeters to inches, you use the conversion factor: 1 inch = 25.4 millimeters.

How many inches are there in 10 meters?
- A.
278
- B.
393
- C.
403
- D.
782
Correct Answer
B. 393Explanation
To convert meters to inches, you use the conversion factor: 1 meter = 39.37 inches.

How many feet is 2.1 meters equal to?
- A.
4 feet
- B.
5 feet
- C.
6.89
- D.
10 feet
