Answer:
$150
Step-by-step explanation:
Let the account earns 5% APR as simple interest for the invested principal. 
Now, the formula of simple interest gives that, 
 , where A is the final amount, P is the principal amount invested, r is the % of interest and t is the number of years for which the principal is invested.
, where A is the final amount, P is the principal amount invested, r is the % of interest and t is the number of years for which the principal is invested.
So, the interest earned will be given by, 
Hence, in our case, $300 is invested for 10 years at a simple interest of 5%. So,   dollars.
 dollars.
Therefore, the amount of interest earned will be $150. (Answer)
 
        
             
        
        
        
Answer:
False
Step-by-step explanation:
If this number is larger than 6, then its square is larger than 36.
If x > 6, then x² > 36
The number is not larger than 6.therefore Its square is not larger than 36.
x ≤ 6; therefore, x² ≤ 36
-7 is < 6; however -7² > 36 as -7² = 49
 
        
             
        
        
        
If the problem is 6r•s•4rt•10rst, then the answer is 240•r^3•s^2•t^2.
