Divide the hexagon into 6 congruent triangles. The cut lines will start at the center and extend out to the vertices. See attached image to see what I mean. Each of the six triangles are the same, so we need to find the area of one triangle and then multiply that result by 6. Each triangle has a base of 5 cm and a height of 4.3 cm, so the area of a single triangle is A = base*height/2 = 5*4.3/2 = 10.75 square cm
Multiply this by 6 and we get 6*10.75 = 64.5 square cm which is the final answer (choice A)
Answer:
<h2>The year is 2010.</h2>Step-by-step explanation:
The population of wolves is given by P(t) = 80(0.98)t.
The study has began in the year of 2000 and will end in 2020.
The difference between 2000 and 2009 is 9 years and the difference between 2009 and 2020 is 11 years.
Hence, the maximum value of t is 11.
The domain is .
The population will be 80, that is P(t) = 80.
Hence, 0.98t = 1, or, t = ≅1.
In (2009 + 1) = 2010, the population of wolves will be 80.
