Answer:
To determine whether a decimal is rational or not, you need to know that...
Irrational numbers don't end and have no pattern whereas rational numbers are the complete opposite. Rational numbers end and have a repeating pattern.
Step-by-step explanation:
Here are examples of irrational numbers:
0.9384903204..... , π , √2
Examples of rational numbers:
0.777777... (is rational because it has a repeating pattern of 7) , √49
Hope this helps :)
Keep trying at this question, I believe in you! Here's the answer just in case. :)
Answer: 0.83644865915
Nearest hundredth would be 0.84.
I can explain it if you'd like.
Edit: Here's how I did it just in case anybody wants to know :) Not that anybody wants to know but just in case because you never know! :)
SOH CAH TOA
sine=opposite/hypotenuse
cosine=adjacent/hypotenuse
tangent=opposite/adjacent
So the cosine of W would be 65(the adjacent side)/97(the hypotenuse)
Because you don't know what W equals, you'd use a calculator and click the little 2nd button, then click the cos button. And then you'd type in the 65/97 and hit the equals button and that's the answer!
If I'm incorrect I guess tell me somehow? Alright, have a great day/night! ^-^

Answer: Numerator
Step-by-step explanation:
The numerator is the number on top of the fraction bar.
The denominator is the fraction under the fraction bar.
For example: 3 <--- numerator
--
4 <--- denominator
It can also be written like 3/4, it means the same thing.
Hope this helps :)
