Answer:  $1.5
Step-by-step explanation:
$3.00 divided by 2 pounds is $1.5
$4.50 divided by 3 pounds is $1.5
and $6.00 divided by 4 pounds $1.5
 
        
             
        
        
        
We have the perimeter of first dimension 2(8 + 4) = 24;
The perimeter of the second dimension is 2( 8 + 54 + 4 + 54 ) = 240
We calculate p/100 = 24/240;
Then p/100 = 1/10;
p = 100/10;
p = 10;
Finally, 10% is the answer.
        
             
        
        
        
The mean is the average you're used to, where you add up all the numbers and then divide by the number of numbers. The median is the middle value in the list of numbers. Mode is the number which appears most often in a set of numbers. 
Hope this helps you :)
 
        
             
        
        
        
Answer:
4.4%
Step-by-step explanation:
solution:
principal (p) = $300
time(t) = 3 years
interest (I ) =$40
rate (r) = ?
 we know that,
I = (PTR)/100*
OR, 40 = (300 *3 * R)/100
or, 40 = (900R)/100
or, 40 = 9R
or, 40/9 = R
or, R = 4.4%
Rate(r) =4.4%
