Part A.
The venn diagram is attached. In the venn diagram, circle A represent the number of responds that have an ASU parking deal. Circle B represent the number of respondents that ride their bike to campus and circle C represent the number of respondents that that ride the Light Rail.
Part B.
From the venn diagram, the number of respondents that ride the Light Rail and ride their bike to campus is given by 39 –
12 = 27
Part C.
From the venn diagram, the number of respondents that only have an ASU parking decal is given by <span>77 –
12 – 8 – 6 = 51
Part D.
The number of respondents that ride the Light Rail or have an ASU decal is given by the sum of the number of respondents that ride the Light Rail only and those that have an ASU parking decal and those that have both ASU parking decal and ride their bike to school.
This is given by 51 + 8 + 28 = 87.
Part E.
The venn diagram showing the area </span><span>that represents people who have a parking decal or who ride their bike to campus but who do not ride the Light Rail</span> sgaded is attached.
a. Pentagon
Interior angle:
5 sides => form 5 triangles => central angle: 360 / 5 = 72°
interior angle = 2x
angles in every triangle: x => x + x + 72° = 180°
=> 2x = 180° - 72° = 108°
Answer 108°
Exterior angles = 360° / number of sides = 360° / 5 = 72°
Answer: 72°
b. 16 - gon
Interior angles: 2x
number of triangles = 16
central angle = 360 / 16 = 22.5°
interior angle 2x, where 180° - 22.5° + x + x => 2x = 180° - 22.5° = 157.5°
Answer: interior angle 157.5°
Exterior angles: 360 / 16 = 22.5°
Answer: exterior angles = 22.5°
c. Dodecagon
number of sides 12
central angle = 360° / 12 = 30°
interior angle, 2x => 30 + 2x = 180 => 2x = 180 - 30 = 150°.
Answer: interior angle = 150°
Exterior angle = 360° / number of sides = 360° / 12 = 30°
Answer: exterior angle = 30°
Answer:
Step-by-step explanation:
side a = 10
Area of isosceles triangle =
=
= 43.3 square units
Answer:
Isolate the radical expression.
Square both sides of the equation: If x = y then x2 = y2.
Once the radical is removed, solve for the unknown.

Answer:
4800
Step-by-step explanation:
8% = 0.08
0.08, or 8%, of 12,000 = 960
960 x 5 = 4800
