Answer: Answer is in the steps read carefully.
Step-by-step explanation:
does not represent a rational number because the square root of 6 is not a perfect square.
This represents a rational number because the square root of 64 is a perfect square which is 8 and if added to a fraction you will get a rational number.
represents a rational number because they are both a perfect square. The square root of 16 is 4 and the square root of 169 is 13.
represents a rational number because since 17.43 repeating can be expressed as a fraction, and the square root of 49 is a perfect square, if added together they will generate a rational number.
Does not represents a rational number because the square root of 44 is not a perfect square and when you add an irrational number and an rational number then you will get an irrational number.
Answer:
6 2/3
Step-by-step explanation:
2 2/5 * 2 7/9
Change each number to an improper fraction
2 2/5 = (5*2+2)/5 = 12/5
2 7/9 = (9*2+7) = 25/9
12/5 * 25/9
Rewriting
25/5 * 12/9
5/1 * 4/3
20/3
Now changing to a mixed number
3 goes into 20 6 times with 2 left over
6 2/3
I believe that’s it .... i’m so so sorry if it’s not
The answer is A. 3° 87+90= 177+ 3= 180°
