The metric system is based upon what number?
- A.
5
- B.
3
- C.
10
- D.
25
Correct Answer
C. 10Explanation
The metric system is based on the number 10. This means that all measurements in the metric system are based on powers of 10. This makes conversions between different units of measurement much simpler, as you only need to move the decimal point to the left or right to change the size of the unit. For example, there are 1000 millimeters in a meter, 100 centimeters in a meter, and 10 millimeters in a centimeter. This base-10 system is widely used around the world and is considered to be more logical and easier to use than other systems based on different numbers.Rate this question:

________kL = 3400L
Correct Answer
3.4, 3.40, 3.4kLExplanation
The given equation shows that 1 kiloliter (kL) is equal to 1000 liters (L). Therefore, when converting from kL to L, we need to multiply the given value by 1000. In this case, 3.4kL is equal to 3.4 multiplied by 1000, which is 3400L. The other two options, 3.4 and 3.40, are already given in liters and do not require conversion.Rate this question:
