Circumference 
2*pi*r
2*(22/7)*(9/2)
2*(11/7)*9
198 / 7
28.28 cm

babymother [125]

Answer:

a) Jean b) Jean c) Vincent d) Jean              

Step-by-step explanation:

We are given the following information in the question.

Vincent can bake 10 cakes or make 5 pizzas

Jean can bake 12 cake or make 8 pizzas.

a) Absolute advantage of baking cake

Jean has the absolute advantage of baking cake as he can bake more cakes as compared to Vincent.

b) Absolute advantage of making pizza

Jean has the absolute advantage of making pizza as he can make more pizzas as compared to Vincent.

In order to find comparative advantage, we find the opportunity cost which can be defined as:

\text{Opportunity Cost} = \displaystyle\frac{\text{What one sacrifices}}{\text{What one gains}}

c) Comparative advantage in baking cakes

Opportunity cost of Vincent for baking cakes = \frac{5}{10} = \frac{1}{2}

Opportunity cost of Jean for baking cakes = \frac{8}{12} = \frac{2}{3}

The less is the opportunity cost the better, hence, Vincent has comparative advantage in baking cakes.

d) Comparative advantage in making pizzas

Opportunity cost of Vincent for making pizzas = \frac{10}{5} = 2

Opportunity cost of Jean for making pizzas = \frac{12}{8} = \frac{3}{2}

The less is the opportunity cost the better, hence, Jean has comparative advantage in making pizzas.

Step-by-step explanation:

Note: ∈ means 'belongs to the set of' and <em>R</em> is 'the set of all real numbers'

Inequality:

- Domain is: x ∈ <em>R</em>

- Range is: x ≥ -2

Set:

-Domain is: {x| x ∈ <em>R</em>}

- Range is: {y| y ≥ -2}

Interval:

- Domain is: (-∞,∞)

- Range is: [-2, ∞)

g(x) is stretched by a factor of 4 and translated 2 units down.

Help pls show work too :)
lutik1710 [3]

Answer:

60 degrees

Step-by-step explanation:

because two inner angles equals the opposite side's outer angle, we can do this

3y + 13 + 4y = 118

we combine like terms

7y + 13 = 118

subtract

7y = 105

and then divide

y = 15

then we do the equation for A's angle

4(15) = 60
