1) 6^2+9^2= x^2
2) 36+81= 117
Square root 117 =10.82
Hope this helped :)
Answer:
7/12
Step-by-step explanation:

Answer:
x = 98 , x = 20.5
Step-by-step explanation:
= 7 ( multiply both sides by 14 to clear the fraction )
x = 98
= 4.1 ( multiply both sides by 5 to clear the fraction )
x = 20.5
Sum greater than 9 from the Sample Space are:
{(4,6),(5,5),(5,6),(6,4),(6,5),(6,6)}
so, in total 6 out of total 36 combinations have a sum greater than 9
So, 

Probability(sum>9)=0.167
(9×10^5)(6×10^-7) = 9×6×10^5×10^-7
=54×10^(5-7)
=54×10^-2
=0,54
