Answer:
1 - c
2 - A
Step-by-step explanation:
Hey There!
So for the first one we are given the dimensions of a rectangular prism and they want us to find the volume 
Remember to find the volume we use the equation 
V = length x width x height 
so we just plug in the values 
v = 2.6 x 2.1 x 3.9 = 21.294
the closest is 20 so C is your answer 
For the second one we are given a triangular prism 
and they want us to find the volume 

b = base (10.3)
l = length (4)
h = height (7)
7x4=28
28x10.3=288.4
then we divide by 2
288.4/2=144.2
so your selected answer is correct 
 
        
             
        
        
        
37292827 the answer is that
        
                    
             
        
        
        
Answer:
210 ways
Step-by-step explanation:
In the question, the combination should be computed.
 Number of ways of selection 6 flowers = nCr =10C6
                                             =
  =
                                                         =3628800/17280
                                                        =210
Therefore, there are 210 ways in which 6 flowers can be selected from the available 10 flowers. 
 
        
             
        
        
        
The second choice is the answer
