Answer: The area common to both triangle is 31.77 sq. cm.
Step-by-step explanation:
Since we have given that 
30-60-90 triangles are placed.
So, the ratio of sides would be 

Since Hypotenuse = 12 cm
So, it becomes,

So, Base would be 

and Perpendicular would be 

So, Area common to the both triangles would be 

Hence, the area common to both triangle is 31.77 sq. cm.
 
        
             
        
        
        
Answer:
3rd and 4th options are correct that is 24 hours per day and 7 days per week.
Step-by-step explanation:
We need to find the conversion factors that can be used to find number of hours in a week.
We know that,
Number of hours in a day = 24
and
Number of days in a week = 7
So, Number of hours in 7 days = 24 × 7 = 168.
Therefore, 3rd and 4th options are correct that is 24 hours per day and 7 days per week.
 
        
             
        
        
        
We know the compound interest formula is given by

Now, we have been given that 24,000 is invested for 2 years with an APR of 6% and daily compounding. Thus, we have

On substituting these values in the above formula for the compound interest, we get

Therefore, the balance in the account after 2 years is 27059.7
