Generally, yes. Some soft cheeses require refrigeration, but many hard cheeses are shelf-stable. They are more likely to dry out than to spoil.
As always, if it smells bad or feels slimy, throw it away.
I highly doubt it because mac and cheese has dairy products in it which tend to curd or spoil in high temps.
Cut top to bottom, left to right, then horizonatally to make two layers.
It should be fine, especially if it's a harder cheese. The best test is to look and smell - if it looks and smells ok, it won't make you sick to taste it. If it tastes ok, you're all good! Nothing major can happen to cheese overnight.
Cheese is milk, curdled and left to mold, then they mix and it becomes cheese
I didn't eat a slice of pie, I ate a pie - so no slices are left.
This depends on if the packaging has been opened or not. If it has , you are right at the door of bacteria contamination. If not the product is still good to eat.
I would not risk using it.
Assume there were twelve slices. 1/4 is 3 slices, 1/3 is 4 slices. That would leave 5 slices.
Its recommended not to eat it after being in the deep freeze for 6 moths, but people still do. Being that its cheese it might not be a good idea but the culture used in blue cheese is pretty safe. So if your going to heat it up and make fondue after 8 months go for it
How many is some? To figure it out: 8-x=_____ x=number of slices eaten
This depends on whether you ate 1 slice, which would leave 3; 2 slices, which would leave 2, or 3 slices, leaving only 1.
One sixth or 1/6...assuming the pizza was cut into 6 slices. If not, then the fraction left would be: (total # of slices cut - 5)/total # of slices cut
