What is the fraction 2 over 3 written in decimal form!!!!!!!!!

vodomira [7]

This is a number you will have memorized in grade school. If not, you can always perform long division of 2 by 3 to find it---or ask your calculator.

2/3 = 0.6666_6 . . . . . . repeating 6s indefinitely

____
Most folks get tired of writing 6s after a couple million of them, so they round it off to 0.67 or 0.667. These rounded values are NOT exactly 2/3.

Find a counterexample to show that the statement is false. Assume all sets are subsets of a universal set U = {1, 2, 3, 4, 5}. (

natka813 [3]

Answer:

For subsets A={1,2},B={2,3},C={1,2 5} of U = {1, 2, 3, 4, 5}.

A ∪ (B − C) = (A ∪ B) − (A ∪ C) does not hold.

Step-By-Step Explanation:

U = {1, 2, 3, 4, 5}.

A={1,2}

B={2,3}

C={1,2 5}

For the Left Hand Side

B-C={3}

A ∪ (B − C)= {1,2} ∪ {3} ={1,2,3}

Likewise, the Right Hand Side:

(A ∪ B)={1,2,3}

(A ∪ C)={1,2,5}

(A ∪ B)- (A ∪ C)= {1,2,3}-{1,2,5}={3}

Since, {1,2,3} ≠ {3}, A ∪ (B − C) = (A ∪ B) − (A ∪ C) does not hold.

Plzzzzz helpppp with my mathhh

soldi70 [24.7K]

The answer is 15 because to the the lenght of the missing number you have to use the Pythagorean Theorem.So first you have to use c^2=a^2 +b^2.
25^2=20^2 + b^2 then 625=400 + b^2. 625-400= 225. So what equals 225. The answer is 15. Hope this helps
