Round 231469.335329 to the nearest thousand

The nearest thousand value for 231469.335329 is 232000.

Step-by-step explanation:

     The given is 231469.335329

     we need to find the nearest thousand value of given,

     If the last digit of the number is above 5 or equal to 5 then the 1 is added to pre digit of last number and last digit is replaced by zero.

    From the given value,

            231469.335329 the digit after the point is less than 5 so we eliminate the value without adding 1.

            231469.00

            In the above value 231469 we add one to the before the last digit, it becomes 231470

           Next to add the number in the 2 digit by adding 1 to before the 2nd digit, it becomes 231500.

          Finally carry out the process of adding one to the 4 digit depends on the values of 3rd digit, it becomes 232000.  

the first option i believe

step-by-step explanation:

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
