A scientist records the following temperatures in degrees Celsius: $$-5$$ , $$3$$ , $$-2$$ , $$0$$ . Which temperature is closest to zero? Explain your reasoning.

$$0$$ , because it is exactly zero

$$-5$$ , because it is the smallest number

$$-2$$ , because it is the closest negative number to zero

$$3$$ , because it is the largest number

A hot air balloon rises $$120$$ meters above the ground, while a submarine dives $$120$$ meters below sea level. Represent both situations using rational numbers and explain what zero represents in this context.

$$+120$$ and $$-120$$ ; zero is ground/sea level

$$+120$$ and $$-120$$ ; zero is the average of the two

$$-120$$ and $$+120$$ ; zero is the maximum height

$$+120$$ and $$-120$$ ; zero is the minimum depth

A bank account has a balance of $$-45$$ dollars. If $$45$$ dollars is deposited, what is the new balance? What does zero represent in this context?

$$0$$ ; zero means the account is balanced

$$45$$ ; zero means the account is overdrawn

$$-45$$ ; zero means the account is empty

A hiker climbs $$30$$ meters up a mountain and then descends $$50$$ meters. Represent these changes as rational numbers and compare their positions relative to zero.

$$+30$$ and $$-50$$ ; $$-50$$ is farther from zero

$$+30$$ and $$-50$$ ; $$+30$$ is farther from zero

$$-30$$ and $$+50$$ ; $$+50$$ is farther from zero

$$+30$$ and $$-50$$ ; both are the same distance from zero

A diver is $$-18$$ feet below sea level. What is the absolute value of his position, and what does it represent?

$$18$$ ; the distance from sea level

$$-18$$ ; the diver's position below sea level

$$0$$ ; the diver is at sea level

$$-36$$ ; twice the distance from sea level

If the temperature changes from $$-7^\circ$$ C to $$5^\circ$$ C, what is the total distance the temperature moved from zero? Use absolute value in your explanation.

$$12^\circ$$ C, because $$|-7| + |5| = 12$$

$$2^\circ$$ C, because $$5 - (-7) = 12$$

$$7^\circ$$ C, because $$|-7| = 7$$

$$5^\circ$$ C, because $$|5| = 5$$

A football team lost $$12$$ yards on one play and gained $$8$$ yards on the next. What is the absolute value of the difference in yards, and what does it represent?

$$20$$ yards; the total yards changed

$$4$$ yards; the total yards gained

A student claims that $$|-9| > |7|$$ . Is the student correct? Explain your answer.

No, because $$|-9| = 9$$ and $$|7| = 7$$ , so $$9 > 7$$

Yes, because $$|-9| = -9$$ and $$|7| = 7$$

A mountain climber is $$-200$$ meters below the peak and another is $$+150$$ meters above the base. Who is farther from the base, and by how much? Use absolute value to explain.

The climber at $$-200$$ meters; $$|{-200}| = 200$$ meters

The climber at $$+150$$ meters; $$|{150}| = 150$$ meters

The climber at $$+150$$ meters; $$|{-200}| = 150$$ meters

What is absolute value?

the distance a number is from 0
