Changing the third group of characters (after the second underscore) from "b53f" to "b541" increases the number from 770 to 7,700. None of the other changes result in a logical or reasonable number.

Question 7

Which metric unit should you use to measure the mass of a bar of handsoap?

Accepted Answer

The most appropriate metric unit to measure the mass of a bar of hand soap is grams (g) as the quantity of the soap is relatively small, and it is measured in a laboratory or a home setting. A bar of hand soap usually weighs around 100-150 grams on average. Therefore, using larger metric units such as metric tons or kilograms would be excessive and unnecessary. The unit of centigrams (cg) could also be used, but grams are more commonly used in everyday situations.

Question 8

This elevator has a load limit of 2200 _____.

Accepted Answer

The most appropriate unit for measuring the load limit of an elevator is kilograms (kg), which is the standard unit of mass in the International System of Units (SI). The other options (metric tons, g, mg) are either too large or too small to be practical for this purpose.

Question 9

Which is larger, 1 gram or 1 milligram?

Accepted Answer

1 gram is larger than 1 milligram. There are 1000 milligrams in a gram, so 1 gram is 1000 times larger than 1 milligram.

Change 1,760 g to kg.

Accepted Answer

To convert grams to kilograms, you divide the number of grams by 1,000 because there are 1,000 grams in a kilogram. Therefore, 1,760 g divided by 1,000 equals 1.76 kg.

Question 16

Change 357 g to mg.

Accepted Answer

To convert from grams to milligrams, we need to multiply by 1000. Therefore, 357 g = 357,000 mg.
