because the rectangle area is 40x70 plus the triangle area is 40x50 divided by 2
        
                    
             
        
        
        
3 apples weigh 1 lb.....so 1 apple would weigh 1/3 = 0.3 lbs
        
             
        
        
        
Answer:
c = 53 yd is the answer.
Step-by-step explanation:
a = 45 yd
b = 28 yd
c = ?
According to the Pythagorean Theorem,
a² + b² = c²
45² + 28² = c² 
2025 + 784 = c²
c² = 2809
c = 53 yd
∴ The dog runs 53 yd
 
        
             
        
        
        
The sum of Heptagon’s inner angles is 180*(7-2)=900 degree
So x=900-146-122-142-140-110-142=98
        
             
        
        
        
When written in scientific notation, 
that number looks like this:
                 3.308 x 10⁶      .
