10 is 20 degrees
11 is 180-145= 35 degrees
12, so the way you do it is by the fact that one opposite exterior angle is equal to two interior angles, so 40+46= 86 degrees.
8 is 86-35= 51 degrees
9 is 29 plus 62 equals 91 degrees.
Hope this helps! I tried to type this really fast
+/- 13 I believe is the correct answer
Answer:
only students who have recess at 12 p.m. or later may go out
Step-by-step explanation:
Let the time after midnight be represented by t, and the temperature be y. Since the temperature increases by 1.2 degrees Fahrenheit each hour, the time taken to reach 32 degrees Fahrenheit can be gotten from:
y = 1.2t + 18
put y = 32
32 = 1.2t + 18
1.2t = 14
t = 14/1.2 = 11.67 hours
Since the recess starts at half hour or hour, hence the recess would start at t = 12 hours, i.e. at 12 p.m.
Hence only students who have recess at 12 p.m. or later may go out
