Answer:
The answer is 72 square units
Step-by-step explanation:
If rectangle A is scaled by 150% that means the length and breadth of rectangle A were both increased by 1.5(150%) to yield rectangle B.
So, the area of rectangle B is 1.5L x 1.5B = 2.25LB
But, LB = area of rectangle A which is = 32
So, area of rectangle B 
= 2.25 x 32
= 72square units.
 
        
                    
             
        
        
        
She washed 30 plates from 7:30 to 7:35.....so she washed 30 plates in 5 minutes.....30/5 = 6 plates per minute
so if she started washing plates at 7:15 and ended at 7:38...how many plates did she wash....
from 7:15 to 7:38 is 23 minutes...and if she can wash 6 plates per minute, then in 23 minutes, she can wash (23 * 6) = 138 plates <==
the equation...
y = -6x + b...with b being the number of plates she started with and x being the number of minutes and y being the plates she has left to wash...I am not 100% sure on this equation...I am so sorry
        
             
        
        
        
Answer:
Step-by-step explanation:
The original price of the math book is 
50$, The amount of money that you have with you is $35.
 If you get a discount of 20%, it means that you get 20% of $50. This is expressed as
 20/100 × 50 = 0.2 × 50 = $10
The new cost of the math book is determined by subtracting the discount from the original price. It becomes 
50 - 10 = $40
Since the amount that you have with you is $35, the amount that you need to borrow in order to buy the math book is 
40 - 35 =$5
 
        
             
        
        
        
Answer:14pi and 43.98 (2dp)
Step-by-step explanation:
circumference =2xpixr
radius = 14 divide by2 =7
2x pi x 7=14pi
14pi =43.98229715
=43.98 (2dp)
