Answer: It’s -4
Step-by-step explanation:
Answer:
6 sides
Step-by-step explanation:
the interior angle + the exterior angle = 180°
let x be the exterior angle then 2x is the interior angle and
x + 2x = 180
3x = 180 ( divide both sides by 3 )
x = 60
the exterior angle = 60°
the sum of the exterior angles of a polygon = 360°
since the polygon is regular the the exterior angles are congruent, then
number of sides = 360° ÷ 60° = 6
Using proportions, it is found that the life span of the person would be 14 years, 212 days and 22 hours shorter.
---------------------------
- 2 packs a day for 35 years is 40 cigarettes a day for 12775 days, as
. - Thus, a total of 511000 cigarettes, as
. - Assuming each cigarette costs 15 minutes of life, the person loses 7665000 minutes of life, as

- One year has 525600 minutes, thus the person loses 14 years of life, as

- Looking at the decimal part, the person loses 212 days of life, as

- Again looking at the decimal part, 22 hours, as

- Thus, the person loses 14 years, 212 days and 22 hours of life.

0.3x = 0.2 - 0.2x
0.5x = 0.2
x =0.2/0.5 = 2/5
