Square numbers of integers falling between 50 and 90 are: 82 = 64 92 = 81
There are 89 numbers between 1 and 90, inclusive. This is because when counting the numbers between two endpoints, you subtract the starting number from the ending number and then add 1. So, 90 - 1 + 1 = 90. But since we are looking for the numbers between 1 and 90, we need to subtract 1, resulting in 89 numbers.
They are: 9+81 = 90
83+7=90

Yes, in so far as all numbers are squares (of some number). But 90 is not a perfect square.
Square numbers of integers falling between 50 and 90 are: 82 = 64 92 = 81
9 squared plus 3 squared is 90.
There are 89 numbers between 1 and 90, inclusive. This is because when counting the numbers between two endpoints, you subtract the starting number from the ending number and then add 1. So, 90 - 1 + 1 = 90. But since we are looking for the numbers between 1 and 90, we need to subtract 1, resulting in 89 numbers.
They are 81+9 = 90
The sum of prime numbers between 90 and 100 is 97, the only prime number between 90 and 100.
They are: 9+81 = 90

There are an infinite number of mixed numbers in that range that are squares. If you limit it to whole numbers, then there are only four: 36, 49, 64, and 81.
