Luis starts to do a division problem and notices that there is a pattern in the digits to the right of the decimal point.

this number is

1. irrational
2. rational
3. an integer
4. natural

Option: 2 is the correct answer.

                   This number is  Rational.

Rational Number--

A number is said to be a rational number if it could be expressed in the form of p/q where p and q are integers and q is a non-zero number.

Also, the decimal representation of such a number is either terminating( i.e. it ends) or is a repeating decimal i.e. the digits after the decimal repeats themselves i.e. they follow some pattern.

If it is not so then the number is said to be a irrational number.

( Also, the natural number and integers never exist in decimals.

They too come under the category of rational numbers)

                       Hence, the answer is: Rational

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
