Answer:
   $406
Step-by-step explanation:
The amount of interest that Lorenzo's account earns is given by ...
   I = Prt
where P is the principal amount ($400), r is the annual rate (1.5%) and t is the number of years (1).
Lorenzo's interest is ...
   I = $400·0.015·1 = $6.00
Then the balance in Lorenzo's account at the end of one year is ...
   $400 +6 = $406.00

Answer:
   13 cm, 39 cm, 39 cm
Step-by-step explanation:
If x is the short side, then the other two sides are 3x and 3x. The perimeter is the sum of side lengths:
   x +3x +3x = 91
   x = 91/7 = 13
   3x = 3(13) = 39
The length of the short side is 13 cm; the other two sides are 39 cm.
 
        
             
        
        
        
Let x = speed and y = distance
y = x * 45
y = (x - 4) * 70
45x = 70x - 280
-25x = -280
x = 11.2
Put it back into the first equation:
y = 11.2 x 45
y = 504miles
