Melissa planted a sapling in her garden. she measured its height with a ruler. the tree was 15 centimeters tall. after a week, she measured it again. this time, the tree measured 25 centimeters. how many millimeters did the tree grow? the tree grew millimeters in a week.

100 Millimeters

Explanation:

The tree's first measurement = 15 centimeters

The tree's measurement after a week =25 centimeters

The difference in growth = 25 - 15 = 10 cm

Since we are asked to find out how many millimeters the tree grew, we convert our result to millimeters.

Conversion Unit: 1 centimeter = 10 Millimeters

Therefore: 10 cm = 10 X 10 =100 Millimeters

The tree grew 100 Millimeters in a week.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
