Answer: v = 32 degrees
Step-by-step explanation:
The polygon theorem states that for any polygon with n sides, the sum of the interior angles is (n - 2) × 180
The given polygon has 6 sides. Therefore, n = 6
The sum of the angles in the polygon is
(6 - 2) × 180 = 3 × 180 = 540 degrees
Therefore,
119 + 134 + 108 + v + 47 + 2v + 2v - 28
Collecting like terms, it becomes
119 + 134 + 108 + 47 - 28 + v + 2v + 2v = 540
380 + 5v = 540
5v = 540 - 380
5v = 160
v = 160/5
v = 32 degrees
Answer:
-5
Step-by-step explanation:
There was five inches of snow, correct? Now, the five inches are melting. It's kinda like subtraction.
5 - 5
Answer:21v/22
Step-by-step explanation:
Circumference of a circle=2×π×radius
6v=2×22/7×r
7×6v=2×22×r
42v=44r
Radius=42v/44
Radius=21v/22
Answer:
The answer is 75 tests for 150 people.
Step-by-step explanation:
Firstly, with 150 people, we can divide into 15 groups; and the probability of disease is 0.04, there are 6 persons who possibly get disease.
Therefor, the maximum number of groups with an individual getting disease is 6. Then, 6 * 11 tests = 66 tests required.
15 groups - 6 groups with disease = 9 groups of negative with 9 tests.
In conclusion, there are 75 tests required.
