Answer:
the last one(y=2(2/3)^x) is the correct answer
Step-by-step explanation:
I identify two coordinate on the graph (0,2) and (1,3) and I noticed only the last one gives you a appropriate output if you plug the correspond input value
 
        
             
        
        
        
Answer:
$1522
Step-by-step explanation:
M = 7 + 3*J
M = 7 + 3*505
M = 7 + 1515
M = 1522
 
        
             
        
        
        
It would be a. 8/9 because for every 8/9 boy, there is 1 girl. To check this work, you can do 8/9 x 18 which equals 16.
        
                    
             
        
        
        
Answer:
Yes, △ABC ∼ △FED by AA postulate.
Step-by-step explanation:
Given:
Two triangles ABC and FED.
m∠A = m∠B
m∠C = m∠A + 30°
m∠E = m∠F = 
m∠D =  °.
°.
Now, let m∠A = m∠B = 
So, m∠C = m∠A + 30° = 
Now, sum of all interior angles of a triangle is 180°. Therefore,
m∠A + m∠B +  m∠C = 180

Therefore, m∠A = 50°, m∠B = 50° and m∠C =  m∠A + 30° = 50 + 30 = 80°.
Now, consider triangle FED,
m∠D+ m∠E + m∠F = 180

Therefore,  m∠F = 50°  
m∠E = 50° and  
m∠D =  
So, both the triangles have congruent corresponding angle measures. 
m∠A = m∠F = 50°
m∠B = m∠E = 50°
m∠C = m∠D = 80°
Therefore, the two triangles are similar by AA postulate.
 
        
             
        
        
        
Answer:
213.3
Step-by-step explanation:
The volume of a pyramid is 1/3 base times height. 
Using this formula, our square base is 8*8, or 64 square units. 
Multiplying that by the height, 10. We get 64*10, 640. 
Finally dividing by 3, we have 213.3333333333... 
Rounding that to the nearest tenth, 213.3.
