Correct answers:
1. There is no value of X that will make the equation true
2. The equation is an identity
4. There are infinite many solutions
5. The equation a contradiction
# of sailboats : # of rowboats = 7:4
# of sailboats = 56
56 / 7 = 8
8 * 4 = # of rowboats
# of rowboats = 32
Answer:
The total number of possible combinations of species that you captured is 11,175.
Step-by-step explanation:
The order that you captured the species is not important. For example, capturing a bird of specie A then a bird of specie B is the same outcomes as capturing a bird of specie B then a bird of specie A. So the combinations formula is used to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

In this problem, we have that:
Combinations of 2 species from a set of 150. So

The total number of possible combinations of species that you captured is 11,175.
A)
lets V be the volume and a width, b the base and h height, s the hypotenuse and A the surface area:
V=1/2abh
V=1/2(5.6)(4.6)(7) = 19.16 inch³
B) A=bh+2ls+lb
A=5(7)+2(5.6)(4.6)+(5.6)(5)= 114.52in²
