There are 80 lights. 28 x 12 divided by 4 minus 4 lights for the 16 inches before the first light.
Answer:
0.08%
Step-by-step explanation:
2 years,
the $800 plus $128 in interest. What simple interest rate did he pay?
128/2
$64 a year
64/800=0.08
so 0.08%
If neighborhood A has 30 homes and increases by 20% each year, we first need to multiply 30 by 20%, which is 6. Next, add the six new houses to the original 30, which is 36. If neighborhood B has 45 homes, but gets three more, that is 48. After one year, neighborhood B has more homes than neighborhood A. Neighborhood A will have more houses than neighborhood B after 4 years. (Five years if you count the starting year.)
