Answer:
the sum of exterior angle of a polygon is always 360 degree.
therefore,
xº+ 2x°+ 4x°+ 6x°+ 8x°+ 9x° +10x° = 360°
40x = 360°
x = 360/40 = 9
x = 9
The answer is choice A, a 3.5% increase.
12/15 = 80%
13/17 = 76.47%
80% - 76.47% = 3.5%

Answer:
The butterfly travels 660 ft in 1.25 min.
Step-by-step explanation:
If the distance, d, a butterfly flies varies directly as the time,t in the air, then we can write the mathematical statement.

If we introduce the constant of proportionality, we obtain;

According to the question, when
,
.
We substitute these values to obtain;



The direct variation equation now becomes

When 


Therefore the butterfly will travel 660 ft in 1.25 min.
