Answer:
260,548668 or 260.55 round to the nearest hundreds  
Step-by-step explanation:
Area of the trapezoid: 
[(major base + minor base)x height]/2 
[(22 + 12) x 12]/2 = 204 cm^2 
radius = diameter / 2 = 12 / 2 = 6 cm 
Area of a semicircle 
(radius^2 x pi)/2 = (6^2 x pi)/2 = 56.548668 cm^2 
total area = 204 + 56,548668 = 260,548668 cm^2 
 
        
             
        
        
        
Answer:
a) 15 ÷ 2/3=
=1 5 x 3/2=45/2
b) 3 × 1/8 × 6/9
=1/8 x 2(  Simplify 3 with 9 remainder 3, reduce 
6 with 3 remainder 2)
=1/4
c) 3 3/5 ÷ 2 2/5
=18/5 : 12/5
=18/5 . 5/12
=3/2
d) 2 1/12 × 1 1/5
= 25/12 . 6/5
=5/2
Step-by-step explanation:
 
        
                    
             
        
        
        
480 bottles because 300 divided by 5 is 60 so then you multiply 60 by 8 and you get 480!
        
                    
             
        
        
        
Your answer is 250 yards you basically just subtract the numbers it gives you from the 294....
        
             
        
        
        
-10.3 + y = 5.2
First, regroup the terms. / Your problem should look like: 
 Second,
Second, add 10.3 to both sides. / Your problem should look like: 
 Third,
Third, add 5.2 + 10.3 to get 15.5 / Your problem should look like: 

Answer: 
y = 15.5 (D)
