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 feet. nextreset

Both elevations or numbers are already expressed as a rational number. This is because a rational number is defined as a number that can be expressed as a quotient or fraction of two numbers:

p / q

Since in this case, q may be equal to 1, then both are rational numbers.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
