Is normal human temperature 94.7 fahrenheit

The normal human temperature is actually around 98.6° F and 97 so you are correct. This is because our body gives out a lot of heat. And the 97 part comes from water that cools down our body so with the water in our body the temperature 36.1°C around 37.

Hope this helped :)
Have a great day

You did not show us the image of the burger, but i shall try to answer as best i can.  when purchasing food, always consider the ingredients as well as the person who prepared it. consider if they were hygienic people or not, in case the burger was infected with bacteria. no mortal should place an infected burger into their mouth.
