Answer:
$2,459.21
Step-by-step explanation:
(see attached for reference)
recall that the formula for compound interest is:
A = P [ 1 + (r/n)^ (nt) ]
where, 
A = Final amount ( we are asked to find this)
P = principal amount = given as $2,340
r = Annual Interest Rate = given as 5% = 0.05
n = number of times compounded in a year = 4 (compounded quarterly)
t= time = 1 year
Substituting the values into the equation, 
A = P [ 1 + (r/n)^ (nt) ]
A = 2,340 [ 1 + (0.05/4)^ (4·1) ]
A = $2,459.21
 
        
             
        
        
        
Answer:
   16
Step-by-step explanation:
Your weight is (roughly) proportional to the inverse of the square of the distance you are from the center of the earth. If that distance is reduced to 1/4 its previous value, then your weight will be multiplied by the factor ...
   1/(1/4)² = 16
You would weigh 16 times as much.
_____
<em>Additional comment</em>
The distribution of mass within the earth also affects your weight.
 
        
             
        
        
        
Answer: 8.6:8.6
Explanation:
1:n is the form you want. 
n is 8.6. change the n value so it is 1:8.6
1 is 1 times bigger than 8.6
8.6 times 1 is 8.6
so you've got 8.6:8.6
your welcome, i hope this helps
 
        
             
        
        
        
Answer: 2
Step-by-step explanation:
First you have to plug in the value for x which is -18 so then you're equation then get y by itself and solve for y. This becomes
-3(-18) -y = 56
54 - y = 56
-54 -54
Y=2 
You can check your work by plugging in 18 for x and 2 for y and when you solve the equation your answer should equal 56.
 
        
                    
             
        
        
        
The second step is to keep your x terms on the left and move the constant to the right by subtracting it from both sides.
