EXPLANATION
The line of reflection from WXY to W'X'Y' is the line y=-x as shown in the following graph:
The equation that you put is correct
d=c-11
Step-by-step explanation:
d is desk
c is chair
The height of the d (desk) is always going to be 11 inches shorter than the chair. So subtract 11 from c (chair) and you will find d (desk).
If the chair is 13 inches....
d=13-11
d=2
If the chair is 32
d=32-11
d=21
This equation will work with numerous numbers to find the size of the desk. If you want you can find the height of the chair as well!
Given:
7 kg turkey
cooking instructions:
over 4kg allow 20 minutes per kg, plus 90 minutes
always leave the turkey to rest for 30 minutes before carving.
7kg * 20 minutes/kg = 140 minutes
140 minutes + 90 minutes = 230 minutes
230 minutes + 30 minutes rest = 260 minutes
260 minutes * 1hr/60 minutes = 4 hours 20 minutes
17:15 is 5:15 pm
17:15 - 4:20 = 12:55 pm
Adam should start cooking at 12:55 pm
