Answer:
?????
Step-by-step explanation:
12x 0.25=?          ?x 5= $?
 
        
             
        
        
        
The surface area of the cube is 1536 square feet because (16×16)×6=1536 square feet. Hope it help!
        
                    
             
        
        
        
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=kx
where
k is the constant of proportionality
Verify each table
table a
Let
x ----> distance
y ----> sound level
For each ordered pair calculate the value of k
k=y/x
so
(5,85) -----> k=85/5=17
(10,79) ----> k=79/10=7.9
the values of k are differents
that means
the table nor represent a proportional relationship
table b
let
x ----> volume
y ----> cost
k=y/x
(16,1.49) ----> k=1.49/16=0.093125
(20,1.59) ----> k=1.59/20=0.0795
the values of k are differents
that means
the table nor represent a proportional relationship
 
        
             
        
        
        
Answer:
8%
Step-by-step explanation:
$30 divided by 100= 0.3/1%
0.3x8=$2.40
$30+$2.4=32.40
 
        
             
        
        
        
It looks like you had some of the numbers correct, but you just labeled it and rounded it incorrectly, and the teacher gave you super partial credit for it.  
For my work, I'm assuming that side A is opposite of angle A and side B is opposite of angle B, etc...
