The tonga trench is at an elevation of 35,702 feet below sea level. the south sandwich trench is at an elevation of 23,737 feet below the sea level. the elevation of tonga trench can be expressed as a rational number as feet. the elevation of the south sandwich trench can be expressed as a rational number as feet.

-35 702 ft; -23 737 ft

Step-by-step explanation:

If sea level is defined as 0 ft, then depths below sea level are negative quantities.

The elevation of the Tonga Trench is -35 702 ft.

The elevation of the South Sandwich Trench is -23 737 ft.

A rational number is a number that can be obtained by dividing two integers.

-35 702 = 35 702/(-1)

-23 737 = 23 737/(-1)

Both numbers are rational.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
