Answer:84.82 volume nearest tenth is = 84.8
Step-by-step explanation: Find the number in the tenth place
88 and look one place to the right for the rounding digit
22. Round up if this number is greater than or equal to
5 5 and round down if it is less than
5.5
Quick answer
Any irrational number. I can't think of any exception to this statement.
sqrt(5) is irrational. 1/2 * sqrt(5) is still irrational.
-sqrt(5) is irrational. -1/2 * sqrt(5) is still irrational
2 + sqrt(5) is irrational. Multiplying this by 1/2 is still irrational.
1/2(2 + sqrt(5) = 1 + 1/2 * sqrt(5) ) is irrational.
Conclusion
There are no exceptions to this. All irrational numbers produce irrationals when multiplied by 1/2
Answer:
B.
Step-by-step explanation:
They all are alternating interior angles so they'll be congruent.





OK now let's plug in the numbers.
