Answer:
No
Step-by-step explanation:
Given
Quadrilateral A: 2,3,5 and 6
Quadrilateral B: 4,5, 8 and 10
Required
Determine if one is a scale of another
To do that, we have to divide the corresponding lengths to give ratio.
Considering Side of A = 2 and Side of B = 4



Considering Side of A = 3 and Side of B = 5



There's no need to check further, since the two ratios calculated so far do not have the same value;
<em>Hence, one quadrilateral is not a scale of the other</em>
 
        
             
        
        
        
Answer:
11 3/13% per annum
Step-by-step explanation:
to find rate= 100×simple interest ÷ (principal ×time)
 simple interest=total amount - principal
 =1,500,000-1,300,000
 =200,000
 =200,000 ×100÷ 1,300,000×4
 =3 11/13% per annum
 
        
             
        
        
        
Answer:
x=4.5
Step-by-step explanation:
Given the equation   , we simplify as:
, we simplify as:

#We further simplify as multiples of 9(divide by 9 to solve for x):

Hence, from our simplification  the equation has the same value as x=4.5
