The circumference of a
timama [110]

9514 1404 393

Answer:

  • 160,000 m²
  • 16 ha

Step-by-step explanation:

The side length of a square is 1/4 of the perimeter, so the side length of the square orchard is (1600 m)/4 = 400 m.

The area of a square is the square of the side length, so the area of the orchard is (400 m)² = 160,000 m².

A hectare is 10,000 m², so the area of the orchard in hectares is ...

  16·(10,000 m²) = 16 ha

Let C(x) be the statement "x has a cat", let D(x) be the statement "x has a dog" and let F(x) be the statement "xhas a ferret".
Arturiano [62]

Answer and Step-by-step explanation:

C(x) be the statement "x has a cat"

D(x) be the statement "x has a dog"

F(x) be the statement "x has a ferret".

Universe = x = all students in your class.

a) A student in your class has a cat, a dog and a ferret   = ∃x(C(x) ∧ D(x) ∧ F(x))

b) All students in your class have a cat, a dog, or a ferret  =  ∀x(C(x) ∨ D(x) ∨ F(x))

c) Some students in your class has a cat and a ferret but not a dog  = ∃x (C(x) ∧ F(x) ∧ ¬D(x))

d) No student in this class has a cat, a dog and a ferret  ¬∃x (C(x) ∧ D(x) ∧ F(x))

e) For each of the three animals, cats, dogs and ferrets, there is as student in your class who has one of the three animals.  (∃xC(x)) ∧ (∃xD(x)) ∧ (∃xF(x))

Evaluate the expression 12-3y÷2+y(2y-4÷y) for y=3
ehidna [41]

Answer:

12 - 3 y ÷ 2 + y( 2 y - 4 ÷ y )   =   21.51.

Step-by-step explanation:

Here, the given expression is:

12 - 3 y ÷ 2 + y( 2 y - 4 ÷ y )

Now, we need to evaluate the given expression for y = 3

12 - 3 y ÷ 2 + y( 2 y - 4 ÷ y )   by the rule of BODMAS

12 - 3 y ÷ 2 + y( 2 y - 4 ÷ y )  = 12 - 3(3) ÷ 2 + 3(2(3) -4 ÷ 3)  

= 12 - 9 ÷ 2 + 3( 6 - 4 ÷ 3)

=  12 - <u>9</u><u> ÷ 2</u> + 3( 6 - <u>4 ÷ </u><u>3</u>)

=  12 - <u>4.5</u> + 3( 6 - <u>1.33</u>)

= 7.5 + 3(4.67)

=  7.5 + 14.01

= 21.51

So,   12 - 3 y ÷ 2 + y( 2 y - 4 ÷ y )   for y = 3  is 21.51.
