4) 28 this is the right answer
You take 120/3=40
So you have 40
80% = 80/100 = 0,8
0,8 x 11 = 8,8
Answer: Initial Temp: 71
Rate of change: -13/1
Step-by-step explanation:
For the intitial temperature, 32 and add 13 three times for each hour. For rate of change it is temperature dropped/ hour
Angle IAK is 28 degrees.
the line I intersects to parallel running lines. I is 180 degrees. there is an angle given to you which is 62. that angle is also the angle for the where line DE intersect with line IJ. so if line IJ is total 180. minus the 62 angle. is 118. line DE and line KL intersect at a 90 angle. so 118 minus 90 is 28. therefore 28 is the answer to the angle IAK.
i hope this all made sense and helped you (:
