Question

Sea level refers to the surface of the ocean. The depth of a body of water can be expressed as a negative number, representing average depth in feet below sea level. The altitude of a mountain can be expressed as a positive number, indicating its height in feet above sea level. The table gives selected depths and altitudes. List the bodies of water in order, deepest to shallowest.

Accepted Answer

Hello everyone. We are given a table and in that table, we express the depth below sea level as a negative number and the height above sea level as a positive number. We want to list the bodies of water and mountains. In order from the deepest to the highest. First number one, we have K Jen Juna with an altitude of 8586 two is Puerto Rico trench with an altitude of negative three. We have Loti with an altitude of 8516 four Mariana trench with an altitude of negative 10, five Hellenic trench with an altitude of negative 5100. Our answer choices are a two is less than one, is less than three, is less than five, is less than four. B two is less than five, is less than three, is less than one, is less than four. C four is less than two is less than five, is less than three, is less than one D four. Is less than three, is less than five, is less than two, is less than one. OK. Looking at my choices. So again, we have numbers one through five and there are altitudes that go with them. We want to start with the deepest. So we want the smallest number or as if you want to think of it as the largest negative number. So the negative number that has the most digits if you will is number four, the Mariana Trench. So that's where I'm gonna begin. So this is the deepest number four with negative 10,911. So that's gonna be less than what comes next. Well, looking at my negative numbers, I see of a negative 8648 and a negative 5100. So negative 8648 would be next. And that's number two, the Puerto Rico Trench. So then that one's gonna be less than our other negative number, which is negative 5100 which is the Hellenic trench, which is number five. So right now we have dealt with our negatives. We have four, is less than two, is less than five. So now we're in the positive numbers and we want the smaller of the two positive numbers, which is gonna be number three at 8516. The lot, I assume it's a mountain will be our next value. And that makes our tallest one, the King Jejuna Moun mountain, which is number one and that has an al tude of 8586. So in order from deepest to highest, we'd have 42531. So that matches answer choice c where four is less than two is less than five is less than three is less than one. Have a nice day.
