6 0

Answer:

25/81

Step-by-step explanation:

The probability of randomly selecting two oranges = (number of oranges in the bowl / total number of fruits in the bowl) x (number of oranges in the bowl / total number of fruits in the bowl)

total number of fruits in the bowl = 5 + 4 = 9

5/9 x 5/9 = 25/81

A 13​-foot ladder is placed against a vertical wall of a​ building, with the bottom of the ladder standing on level ground 5 fee
Tanzania [10]
The answer is 12 because (a^2 + b^2 = c^2) 

5^2 + b^2 = 13^2  
 25  + b^2 = 169
                                                                          
169- 25 = 144    
 \sqrt{144}  Sqaure root of 144 is 12 so If we plug that in..
 25 + 144 = 169 
5^2 + 12^2 =13^2 
This all checks out
