Step-by-step explanation:
Let points D, E and F have coordinates
and 
1. Midpoint M of segment DF has coordinates

2. Midpoint N of segment EF has coordinates

3. By the triangle midline theorem, midline MN is parallel to the side DE of the triangle DEF, then points M and N are endpoints of the midsegment for DEF that is parallel to DE.

Answer:
842 Fahrenheit, 723.15 Kelvin
Step-by-step explanation:
(450C * 9/5) + 32 = 810 + 32 = 842 Fahrenheit
450C + 273.15 = 723.15 Kelvin
50% off. You only have to pay $5. If you do 10% off one time you have to pay $9 and then the next time you get 40% off, you’d have to pay $6.
Unless I completely misunderstood, 50% should be better. If it’s 40% off + 10% then it will be 50% and therefore both of them are equal deals and both good.
