4 is the rotational symmetry
Answer:
The answer is 4 feet and 3 inches.
Step-by-step explanation:
if they are like that they always equal each other.
Well the parking spot columns are 80 feet long since they go all the way its length.
there are 2 columns which are 10 feet wide so we can talk out the 20 feet of aisle width. that would mean there is 77 - 20 feet of width for parking spots so 57 feet
the spots are 8 feet wide apiece and their width is parallel to the length of overall lot so there is up to 80 feet. So how many times does 8 feet fit into 80 feet. 10 times. So so we can have 10 spots for each row of spots.
each spot is 19 feet long and there are 3 rows of spots so 19 * 3 = 57. So they fit exactly 3
so we have 3 rows by 10 columns.
3*10 = 30 apots
Since they are FEWER than 30 total cones, the sum of x small cones and y large one must be LESS THAN 30: x+y <30
He needs AT LEAST a dozen (12), so that means that 12 will work or more than 12:
