How many meters tall is a student whose height is 54.2 inches? Round your answer to the nearest tenth. Question 2 The width of a human hair is 0.065 mm. Convert this quantity to micrometers. Enter a number in standard notation. Question 3 It is common lore that "vodka does not freeze". This is perhaps only true in a conventional freezer. 80-proof vodka will freeze around -16°F. Convert this temperature to Celsius. Round your answer to the nearest hundreth place.

Question 4
A student would like to calculate the density of a metallic solid. The solid was massed on a top-loading balanced and was found to have a mass of 36.49 grams. The
solid was placed in a partially filled 50-mL graduated cylinder and displaced 4.6 mL. Calculate the density of the solid. Enter a number without units.

The water level of a graduated cylinder is initially at 14.08mL. After placing a metallic necklace into the cylinder, the water level rises to 21.4mL. Provided that the
density of the necklace's material is 9.894 g/mL, calculate the weight of the necklace in ounces. A pound is defined as 16 ounces.
Hint: solve for the mass in grams, then convert your answer to ounces.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F707cabdc-1809-4680-b100-3c0d66ee6663%2Fc67fd18a-dab9-47ea-a1ca-eaf28244d15e%2F8lm0dwv_processed.jpeg&w=3840&q=75)
