Answer:
150:120
Step-by-step explanation:
U add the 2 ratios 5+4=9
270/9=30
30*5=150
30*4=120
Percent change = [(45 - 60) / 60] x 100 = -25 % (decrease)
<span>Total lot - house -other side
=(56 ft 9 in) - (34 ft 10 in) - (5 ft 5 in)
=(55 ft 21 in) - (34 ft 10 in) - (5 ft 5 in)
=16 ft 6 in
Convert to inches: </span>16 ft x 12 in/ft)+ 6 in= Total in inches<span>192 in + 6 in= Total in inches
198 in= Total in inches
Check: One side + house + other side = Lot width
(5 ft 5 in)+(34 ft 10 in)+(16 ft 6 in)=Lot width
56 ft 9 in=Lot width, which equals the given.</span>
Now, If the exponent was negative like you asked....
