Area of a rectangle is length x width.
So the area is 15000 because 150 x 100 = 15000
        
                    
             
        
        
        
Answer:
The answer is 30
Step-by-step explanation:
First you have to find 120% of a (12).

Therefore; 14.4 is 80% of b, and we are trying to find 100% of b

we do not know what is 100% therefore we call it *x*. In order to find this unknown value *x* we cross multiply.

This is the same as saying;

100% percent would be 1 because it is the whole number we are trying to find. The 80% would be 4/5. To get 4/5 you can simply break down 80/100 ( this is 80% as a fraction).
so the new equation is: 14.4= 4/5x
We divide both sides by 4/5. Then we will get x tobe equal to 18. Therefore b is 18. We were asked to find (a + b) so.<em> </em><em>1</em><em>8</em><em>+</em><em>1</em><em>2</em><em> </em><em>=</em><em> </em><em>30</em>
 
        
             
        
        
        
Answer:
14x
Step-by-step explanation:
14x = 14 x (x) = 14(x)
 
        
             
        
        
        
Answer:
a) B
b) draw a closed circle right before 0.1 (where 0.083 would be)
c) 1/12
 
        
             
        
        
        
Answer:
74/100 OR 37/50 
Step-by-step explanation:
First add everyone together since its asking for no cold / everyone. 
41 + 15 + 12 + 5 + 21 + 6 = 100
Then add to gether the total of people without a cold. 
41 + 12 + 21 = 74 
Next you just put the ratio in order which in this case would be no cold / everyone then if possible simplify. 
74/100 = 37/50
