In which pair do both decimals represent rational numbers? O A. 2.71828182845904523536... and 0.1222
O B. 3.141592653589793238... and 0.684
O C. 3.141592653589793238... and 0.1222...
O D. 0.684 and 0.1222...

Option (B)

Step-by-step explanation:

Properties of a rational number:

1). A decimal number which has the repeating numbers after decimal is a rational number.

Example: 2.134134134......

Here 134 is repeating after decimal so the number is a rational number.

2). A decimal number which can be written as a fraction is a rational number.

Example: 0.25 =

Here 0.25 can be written as a fraction therefore, its a rational number.

In the given options,

Option A

No repeating numbers in first number therefore its an irrational numbers.

Option B

0.684 =

Option C

First number is an irrational number.

Option D

First number is an irrational number.

Therefore, Option (B) is the answer.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
