Question

16. If we denote the height of a place above sea level by a positive integer and depth below the sea
level by a negative integer, write the following using integers with the appropriate signes
(a) 200 m above sea level (b) 100 m below sea level
(c) 10 m above sea level
(d) sea level​

Answer 1

Step-by-step explanation:

Given that,

Height of a place above sea level is denoted by a positive integer and

Depth below the sea level is denoted by a negative integer

Therefore,

(a) 200 m above sea level =+200

(b) 100 m below sea level =−100

(c) 10 m above sea level =+10

(d) Sea level =0.

Answer 2

Answer:

a) +200 m

b) -100 m

c) +10 m

d) 0 m

Step-by-step explanation:

a) +200 m ( As it is above sea level so, it will be +ve with sign)

b) -100 m ( As it is above below level so, it will be -ve with sign)

c) +10 m ( As it is above sea level so, it will be +ve with sign)

d) 0 m ( As it is at sea level so, it will be 0)
