To find this you add both of the other angles and when you do that is what the last angle must equal
Lerok [7]2 years ago
4 0
The angle immediately below x makes up the third angle of the isosceles triangle whose base angles are 55°. That third angle and x are "vertical" angles, hence equal. The value of x can be found from the sum of angles of a triangle:
  x + 55° + 55° = 180°
  x = 70°

The appropriate choice is the 2nd one:
  70°

1) Uma produtora pretende lançar um filme em dvd e prevê uma venda de 20.000 cópias. O custo fixo de produção do filme foi R$ 15
vichka [17]

Answer:

The minimum price that should be charged for dvd, so there is no loss = R $ 27.5

O preço mínimo que deve ser cobrado pelo dvd, para que não haja perda = R $27,5

Step-by-step explanation:

English Translation

A production company plans to release a movie on DVD and plans to sell 20,000 copies. The fixed cost of producing the film was R $ 150,000.00 and the cost per unit was R $ 20.00 (blank DVD, copying and packaging process). What is the minimum price that should be charged for dvd, so there is no loss?

Total cost of production

= (Fixed Cost) + (Variable Cost)

Fixed Cost = R $ 150,000.00

Variable Cost = (Cost of production per unit) × (quantity produced) = 20 × 20000

= R $400,000

Total cost of production = 150,000 + 400,000

= R $ 550,000

Total revenue = (Quantity available) × (Price of 1 unit)

Let the price of 1 unit be p

Total revenue = 20000 × P = 20000p

Profit = (Total revenue) - (Total Cost of production)

For the minimum price that the should be charged for dvd, so there is no loss, profit = 0

So,

Profit = (Total revenue) - (Total Cost of production) = 0

20000p - 550000 = 0

p = (550000/20000) = R $ 27.5

In Portugese/Em português

Custo total de produção

= (Custo fixo) + (custo variável)

Custo Fixo = R $ 150.000,00

Custo variável = (Custo de produção por unidade) × (quantidade produzida) = 20 × 20000 = R $ 400.000

Custo total de produção = 150.000 + 400.000

= R $ 550.000

Receita total = (quantidade disponível) × (preço de 1 unidade)

Seja o preço de 1 unidade p

Receita total = 20000 × P = 20000p

Lucro = (receita total) - (custo total de produção)

Pelo preço mínimo que deve ser cobrado pelo dvd, para que não haja perda, lucro = 0

Assim,

Lucro = (receita total) - (custo total de produção) = 0

20000p - 550000 = 0

p = (550000/20000) = R $ 27,5

Hope this Helps!!!

F(x)= <br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B4x%20-%207%7D%7B10%7D%20" id="TexFormula1" title=" \frac{4x - 7}{10} "
Naily [24]

Answer:

To find f-¹(x) of f(x) equate f(x) to y

That's

f(x) = y

So we have

y =  \frac{4x - 7}{10}

Next interchange the variables that's x becomes y and y becomes x

That's

x =  \frac{4y - 7}{10}

Next make y the subject

Cross multiply

We have

4y - 7 = 10x

Move -7 to the right side of the equation

4y = 10x + 7

Divide both sides by 4

We have the final answer as

y =  \frac{10x + 7}{4}

So

f ^{ - 1} (x) =  \frac{10x + 7}{4}

Hope this helps you

20.   The sum of two consecutive even integers is 158. Find the least of the two integers. 
Mumz [18]

Answer:

78

Step-by-step explanation:

The tricky part of this is figuring out how to assign the unknowns.  We are told that we are working with two consecutive even integers.  Consecutive means "next to" or "in order" and sum means to add.  If we use 2 and 4 as examples of our 2 consecutive even integers and assign x to 2, then in order to get from 2 to 4 we have to add 2.  So the lesser of the 2 integers is x, and the next one in order will be x + 2.  (2 and 4 are just used as examples; they mean nothing to the solving of this particular problem.  You could pick any 2 even consecutive integers and find the same rule applies.  All we are doing here with the example numbers is finding a rule for our integers.)  Now we have the 2 expressions for the integers, we will add them together and set the sum equal to 158:

x + (x + 2) = 158

The parenthesis are unnecessary since we are adding, so when we combine like terms we get

2x + 2 = 158 and

2x = 156 and

x = 78

That means that the lesser of the 2 integers in 78, and the next one in order would be 80, and 78 + 80 = 158
