i don't know but the question is to circle the object that is heavier(shoe,sock,feather,marble,brick and tape measure)i know a brick,and the tape measure is heavy but i'm not sure about the shoe and the marble
Depending on the shoe, of course. A sneaker would be heavier than a sock, feather, and a marble. A marble is heavier than a sock and a feather.
Astronomers sometimes use angle measures divided into degrees, minutes, and seconds. One degree is equal to 60 minutes, and one minute is equal to 60 seconds. Suppose that ∠J and ∠K are complementary, and that the measure of ∠J is 47 degrees, 24 minutes, 28 seconds. What is the measure of ∠K?
