Answer:
2.379m
Explanation:
The width = 23m
The depth = 3m
The radius is denoted as R
The wetted area is = A
The perimeter perimeter = P
Hydraulic radius
R = A/P
The area of a rectangular channel
= Width multiplied by Depth
A = 23x3
A = 69m²
Perimeter = (2x3)+23
P = 6+23
P= 29
Hydraulic radius R = 69/29
= 2.379m
This answers the question

Answer:
the third statement is true
Explanation:
given data 
Lenovos cost more than Dells
Lenovos cost less than Apples
solution
we have given 1st statement that is express as
cost (Lenovo) > cost (Dell)     ..................1
and 
2nd statement that is express as
cost (Lenovo) < cost (Apple)
so we can say it as 
cost (Apple) > cost (Lenovo)       ......................2
and 
now above Both equation 1 and 2 can be written as 
cost (Apple) > cost (Lenovo) > cost (Dell)      .........................3
so we can say cost of Apples is more than the cost of Lenovos and the cost of Dells 
so as that given 3rd statement is true 
 
        
             
        
        
        
I think the answer is B. 10D
