The 32 species that make up the dolphin family are closely related to whales and in fact include the animal known as the killer whale, which can grow to be 30 feet long and is famous for its aggressive hunting pods.
(A) include the animal known as the killer whale, which can grow to be 30 feet long and is
(B) include the animal known as the killer whale, growing as big as 30 feet long and
(C) include the animal known as the killer whale, growing up to 30 feet long and being
(D) includes the animal known as the killer whale, which can grow as big as 30 feet long and is
(E) includes the animal known as the killer whale, which can grow to be 30 feet long and it is

A

Step-by-step explanation:

- Generally, the agent of a COMMA + VERBing modifier must be the nearest preceding SUBJECT.

- B and C: The 32 species...include the animal known as the killer whale, growing

- Here, COMMA + growing seems to refer to the 32 species -- the nearest preceding subject -- implying that the SPECIES are GROWING.

Not the intended meaning.

- The intended meaning of the original sentence is that THE KILLER WHALE can GROW.

Eliminate B and C.

- In D and E, includes (singular) does not agree with the 32 species (plural).

Eliminate D and E.

- the correct answer is A

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
