Consider the rational number 3/11 a. What are the value of a and b in a divide by b when you use division to find the decimal fo
PolarNik [594]

Answer:

The decimal form of this rational number is 0.\overline {27}.

Step-by-step explanation:

a) Let \frac{a}{b} a rational number. From statement we understand that a represents the numerator, while b corresponds with the denominator of the rational number. Hence, a is 3 and b is 11.

b) The decimal form is obtained by dividing a by b, we presented the step needed to determine the decimal form:

i) Multiply the numerator by 10:

Dividend: 30/Divisor: 11/Known result: 0. /Residue: N/A

ii) Multiply the divisor by 2 and subtract from the dividend:

Known result: 0.2 /Residue: 8

iii) Multiply the residue by 10:

Known result: 0.2 /Residue: 80

iv) Multiply the divisor by 7 and subtract from the residue:

Known result: 0.27 /Residue: 3

v) Multiply the residue by 10:

Known result: 0.27 /Residue: 30

vi) Multiply the divisor by 2 and subtract from the residue:

Known result: 0.272/Residue: 8

vii) Multiply the residue by 10:

Known result: 0.272 /Residue: 80

viii) Multiply the divisor by 7 and subtract from the residue:

Known result: 0.2727/Residue: 3

We have notice that the decimal form of \frac{3}{11} is a periodical decimal number. Hence, we conclude that decimal form of this rational number is 0.\overline {27}.

Solution to (x-2) (x+10) = 13
Grace [21]

Answer:

-11,3

Step-by-step explanation: using foil (x-2)(X+10)=x^2+8x-20

x^2+8x-20-13=13-13 X^2+8x-33=0 factoring you get (x+11)(x-3)=0 so x+11=0

x-3=0

x=-11,3
