Earth has a surface area of approximately 197,000,000 square miles and a total land area of approximately 58,000,000 square miles. what fraction of the earths surface is land? write another fraction that is close to your answer and has a denominator of 10

The desired fraction is 58/197, or approx. 0.29.  This is equivalent to 29/100, or 30/100, or 3/10.

Step-by-step explanation:

Given : Earth has a surface area of approximately 197,000,000 square miles and a total land area of approximately 58,000,000 square miles.

Then fraction of the earths surface is land is given by :-

Hence , the fraction of the earths surface is land =

since 58≈60 and 197≈200

Another fraction that is close to answer and has a denominator of 10=

the answer is a.

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
