If each gallon is $2.85, you multiply $2.85 by however many gallons you buy. so, 1.6 x $2.85 = $4.56.
Answer:
how many bags are there?
Step-by-step explanation:
Answer:
18 sides.
Step-by-step explanation:
The interior and exterior angles sum to 180 so:
I + E = 180
also I - E = 140 (given)
So, adding to eliminate E:
2I = 320
I = 160 degrees and the external angle E = 1809 - 160 = 20 degrees.
Since the sum of all exterior angles in a polygon = 360 degrees
- the number of sides = 360 / 20 = 18.
