4/5, or 80%, of the flowers are not tulips.
Answer:
13, 15
Step-by-step explanation:
Let x represent the smaller of the two integers. Then the larger is x+2. The required relation is ...
x² = 154 +(x +2) . . . . . . the smaller squared is 154 more than the larger
x² -x = 156 . . . . . . . . . . subtract x
x² -x +1/4 = 156.25 . . . complete the square
(x -1/2) = √156.25 = 12.5 . . . . take the square root
x = 13 . . . . . add 1/2
The two integers are 13 and 15.

Answer: 0.0905475920892 miles
Step-by-step explanation:
Convert km to Miles using conversion
1km = 0.6213712 miles
86 x 0.6213712 = 53.4379232 miles/hour
divide that by 60 to get miles per minute. Divide again to get miles per second
53.4379232 / 60 / 60 = 0.0148438675556 miles/second
6.1 x 0.0148438675556 = 0.0905475920892 miles
