156 minutes.
To find this, remember that an hour has sixty minutes. With this information, it is also given that there are two hours, thus meaning that we have to multiply sixty by two. This will give you 120. Next, you need to figure out the 3/5's portion of an hour. To find 1/5 of an hour, simply divide sixty by five. With that, you get the answer of 12. But because it says 3/5, you need to multiply 12 by 3, giving you 36. Finally, you add 36 to 120 to get the final answer of 156.
Hope this helps!
An easier way to do this is to make the fractions improper fractions.
3 1/6 can be rewritten as 19/6. 1 4/6 can be rewritten as 10/6. (Multiply the denominator by the number at its side, and add it to the numerator).
2 3/6 is 15/6.
Subtract 10/6 from 19/6.
19/6-10/6=9/6.
9/6 is not 15/6, therefore she did not use 2 3/6 yards of fabric.
You can use protractors I think
If two lines are intersected by a transversal, and the alternate interior angles are equal, then the lines are parallel.
Conversely, if two lines are parallel, then the alternate interior angles formed by the transversal are equal.
So, Ray can made the conclusion that l and m are parallel because alternate interior angles are equal since m∠3 = m∠6.
