What units in the metic system would you use to measure each of the following quanities?
a. distance from los angeles to new york
b your waist measurement
c. width of a hat
d. your height
The united States emitted 19.5 million t of nitrogen oxides (NO)into the atomsphere in 1987. One metric ton (1t) equals 1,000kg. How many kilograms of NO were emitted to the atomsphere in the United States during 1987?
First of all, the subject of your question is not geometry. It is about basic math and measurements. Geometry is about shapes and angles, together with the lengths of lines.
For your first question, kilometers are the dimensions usually chosen to express distances between places on Earth or in the solar system. For the other measurements, choose the metric dimension that makes most of those human-scale measurements fall in a range from 1 to 100. Except for very young children, most humans are at least one meter high.
For your second question, just multipy the number of metric tons by the number of kg in a metric ton.
Nitric oxides of different types are not written NO; they should be written NOx. This is a point your tecaher or textbook writer may not be aware of.

a. To measure the distance from Los Angeles to New York, you would use kilometers (km) or meters (m).
b. To measure your waist measurement, you would typically use centimeters (cm) or inches (in).
c. To measure the width of a hat, you would typically use centimeters (cm) or inches (in).
d. To measure your height, you would typically use meters (m) or centimeters (cm).
To find the answer to the second question, you need to convert the given metric value into kilograms. Since 1 metric ton (t) is equal to 1,000 kilograms (kg), you can multiply the given value of 19.5 million t by 1,000 to obtain the answer:
19.5 million t * 1,000 kg/t = 19,500,000,000 kg
Therefore, 19.5 million metric tons of NO were emitted into the atmosphere in the United States during 1987, which is equivalent to 19,500,000,000 kilograms.
