Answer:
25 : 2
Step-by-step explanation:
There are US, Indian and British stamps in Jo's collection. He has the US to Indian stamps in ratio 5 : 2 and the Indian to British stamp in ratio 5 : 1.
So, the ratio of US to Indian stamps is 5 : 2 i.e. (5 × 5) : (2 × 5) = 25 : 10
Again, the ratio of Indian to British stamps is 5 : 1 i.e. (5 × 2) : (1 × 2) = 10 : 2
Therefore, the ratio of stamps of the US to Indian to British will be 25 : 10 : 2.
Hence, the ratio of US to British stamps will be 25 : 2 (Answer)

Answer:
5
Step-by-step explanation:
The diagonal divides the square into 2 right triangles.
let s be the side of the square with the diagonal being the hypotenuse.
Applying Pythagoras' identity to one right triangle, gives
s² + s² = 10² , that is
2s² = 100 ( divide both sides by 2 )
s² = 50 ( take the square root of both sides )
s = = = × = 5
