Answer:
It is 13.56
Step-by-step explanation:
You would have to divide 40.68 by 3. 3 goes 1 time into 4 so it is 10.
 
        
                    
             
        
        
        
Multiply the amount of inches it is by 30 and you will know what the size is in feet.

Answer:
   a) ∆ABC ~ ∆EDC by AA similarity
   b) ED/AB = 3/4
   c) 15 cm
Step-by-step explanation:
a) Two angles in each triangle are the same, so the AA similarity postulate can be used to declare the ∆ABC ~ ∆EDC. (Each triangle includes a right angle and angle C.)
__
b) Corresponding sides are ED/AB, DC/BC, EC/AC. The ratio of corresponding sides is ED/BC = (12 cm)/(16 cm) = 3/4.
__
c) Using the ratios identified above, we have ...
   DC/BC = 3/4 = x/(20 cm)
   x = 3/4(20 cm)
   x = 15 cm
 
        
             
        
        
        
you multiply 35 to 72 to get 2520 and then multiply 23 to 94=2139 add both of the answers to get 4659
 
        
             
        
        
        
Answer:
8
Step-by-step explanation:
Let's set this up to see if we can simplify it a bit:

Notice we have 4 tens on top and 3 on bottom, so we can eliminate the bottom 3 altogether and leave just one on top.  And we have 2 fives on the top and 3 on bottom, so we can eliminate the 2 on the top and leave one on the bottom.  Now that looks like this:

10 divided by 5 is 2, and 2 cubed is 8
