Ca3(PO4)2 has a total of 13 atoms.
2 - 1 on 13 and the other after Christmas and all 3 stars
I assume you mean how many possible outcomes when looking at all 13 results. It would be 2^13 = 8192
Assuming the dogs have four feet and birds two, you need 15 dogs (60 feet) and 1 bird (2 feet) giving a total of 16 birds and dogs and 62 feet. None. Dogs have paws, not feet. Also, birds have claws, not feet.
If 2 people make 2 birds each in 55 minutes, then a total of 4 birds are made by these 2 people. Extending this to a larger group, if more people are making birds at the same rate, the number of birds made in 55 minutes will depend on the number of people participating.
2 because canaries are birds and all birds have 2 legs
There are 13 people in total: 2 parents, 6 girls, and 5 boys.
4 Yes, 4 is correct. But, it depends on what type of creature you're asking about. Fish: 2 total; 1 in, 1 out. Birds & Mammals: 4 total; 2 in, 2 out. Reptiles & amphibians: 3 total; 2 in, 1 out. Hope this helps : )
they have 2 eyes

Start with the 5 birds. Subtract the 2 that are red. The number left after subtracting 2 from 5 is the number of green birds.
rabbits = 12 legs Snakes don't even have legs. Birds = 10 legs Total= 22 ---- Oops I wasn't thinking about there front paws!
