Answer:
5.5, 7, 8.5
Step-by-step explanation:
Find the mean of 4 and 10, that is
 = 
 = 7
Now repeat with 4 and 7 and 7 and 10
 = 
 = 5.5
 = 
 = 8.5
Hence
4, 5.5, 7, 8.5, 10 ← is an arithmetic sequence with d = 1.5
 
        
             
        
        
        
Answer:
212.5
Step-by-step explanation:
For triangles, A = (bh)/2
You can do 15+25 to find the base, which is 40. From here do 17*40/2. You get 340. However, you need to remove the right triangle on the left side.
Again do 17*15/2, which you get 127.5.
From here subtract 127.5 from 340 and get 212.5
 
        
                    
             
        
        
        
Step-by-step explanation:
In triangle ADE:
sum of all angles is 180.
3x-10+58+42=180
3x+90=180
3x=180-90
3x=90
x=90/3
x=30
As line DA and CB are parallel:
angle D=angle C
angle y=58
In angle BCE, sum of angles is 180.
z+58+42=180
z+100=180
z=180-100
z=80
 
        
             
        
        
        
13/16= 0.8125

We can set up a proportion, and let x be the amount 16kg would cost: 14/154=16/x. We simplify 14/154 = 1/11. Next, we cross-multiply to get (1)(x)=(16)(11), so x=176. Therefore, 16kg of apples cost $176.
