Anature museum has 2008 specimens are early birds, some with two wings and some with for wings. the specimens have a total of 4038 wings. how many specimens are there with each number of wings?

If each bird had two wings, there would be 4016 wings. For each two-winged bird we replace with a four-winged bird, the total number of wings would increase by 2. We need 22 more wings, so 11 two-winged birds need to be replaced by four-winged birds. Thus, there are 1997 two-winged and 11 four winged birds.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
