Answer:

La cantidad de pasajeros que quedan en el avión serán [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

Sabes que en el primer aeropuerto se bajan la mitad de los pasajeros, es decir que se bajan [tex]\frac{1}{2}[/tex] pasajeros, y en la segunda parada llegando a destino se bajan [tex]\frac{1}{3}[/tex] pasajeros. Entonces, la cantidad de pasajeros que se bajan en ambas paradas es la suma de la cantidad de pasajeros que se bajaron entre el primer y segundo aeropuerto:

[tex]\frac{1}{2}+\frac{1}{3}[/tex]

Lo primero que debes hacer es hayar un denominador común entre el 2 y el 3. Para eso, hallas el mínimo común múltiplo entre ambos, en este caso 6.

Luego debes multiplicar cada numerador por el número que hayas multiplicado el denominador. Para ello, dividis este mínimo común múltiplo entre el denominador inicial, y este resultado se multiplica por el numerador de esa fracción. De esta manera se obtiene:

[tex]\frac{1}{2}+\frac{1}{3}=\frac{3}{6} +\frac{2}{6}[/tex]

Finalmente se suman los numeradores y se obtiene:

[tex]\frac{1}{2}+\frac{1}{3}=\frac{5}{6}[/tex]

Considerando que 1 es un entero que representa la cantidad de total de pasajeros, para calcular la cantidad de pasajeros que quedan en el avión se realiza la sustracción:

[tex]1-\frac{5}{6}[/tex]

Resolviendo de manera similar a la suma, se obtiene:

[tex]1-\frac{5}{6}=\frac{6}{6} -\frac{5}{6}[/tex]

[tex]1-\frac{5}{6}=\frac{1}{6}[/tex]

Entonces la cantidad de pasajeros que quedan en el avión serán [tex]\frac{1}{6}[/tex]

Answer:

no

Step-by-step explanation:

A proportional relationship must go through the point ( 0,0).  This does not go through the origin so this is not proportional

The relationship is linear but non proportional. The graph is a line but it does not go through the origin.

Step-by-step explanation:

-2a+6=12

collect like terms

-2a=12-6

-2a=6

divide both sides hy the coefficient of a

-2a/-2 =6/-2

a= -3

Answer:

B. It is a composite number.

Step-by-step explanation:

143 can be divided by 11 and 13 making it a composite number.

The number 143 is a composite number due to having more than two factors.

The factors of the number 143 are 1, 11 and 13.

Prime number has only two factors i.e. 1 and the number itself while composite numbers can have more than two factors.

143 = 1*11*13

Since the number 143 has 3 factors i.e. 1, 11, and 13.

So, The number 143 is a composite number.

Therefore, The number 143 is a composite number due to having more than two factors.

Answer:

30 - 3t ≤ 20

Step-by-step explanation:

Given that :

Pool is open when high temperature is higher than 20°C

From 30°C ; temperature decreased at a constant rate in the next three days ; that is the daily fall in temperature for 3 days is the same.

Let the fall or decrease in temperature = t

Constant decrease for 3 days = 3t

Change in temperature over 3 days :

Initial temperature - constant decrease

30°C - 3t

Hence, inequality to determine rate of temperature decrease :

30 - 3t ≤ 20

Joy makes 6.5 litres soup correct to the nearest 0.5 litres. She serves the soup in 280ml portions correct to the nearest 10ml. 22 people order this soup. Does joy definitely has enough soup to serve the 22 people.

Answer:

Yes, Joy definitely does has enough soup

Step-by-step explanation:

From the question, we know,

Joy make 6.5 litres of soup

Serves it in 280ml portions

Step 1

We convert the portions to liters

1 ml = 0.001 litre

280 ml

= 280ml × 0.001 litre/1 ml

= 0.28litre

Step 2

We divide 6.5 liters by 0.28 to find out how many people can be served

= 6.5 ÷ 0.28

= 23.2142857143 people

We can see that 6.5 liters soup can serve 23 people approximately.

Therefore, Yes, Joy definitely does has enough soup to serve 22 people

Answer: 80 sq. ft

Step-by-step explanation:

Company A’s charges can be represented by the equation: 10m + 250

Company B’s charges can be represented by the equation: 12m + 90

To find when the square feet got which they have the same amount, I will set them equal to each other and solve for it.

10m+250=12m+90

-10m -10m

250=2m+90

-90 -90

160=2m divide both side by 2

80=m

For 80 square feet, both companies charge the same amount.

Answer:

P=4x+20

A=x^2+10x+21

Step-by-step explanation:

Perimeter=2(x+7)+2(x+3)

2x+14+2x+6

4x+20

Area=(x+7)(x+3)

x^2+10x+21

l = (x + 3)

b = (x + 7)

Area:

= I x b

= (x + 3)(x + 7)

= x(x + 7) + 3(x + 7)

= x² + 7x + 3x + 21

= x² + 10x + 21

Perimeter:

= 2(l + b)

= 2((x + 3) + (x + 7)) = 2(2x + 10)

= 2(x + 3 + x + 7)

= 4x + 20

Answer:

Hence the weight of chalk stick is 25 g.

Explanation:

Let the weight of a stick be x gm.

12% of x=3

(12/100)*x=3

x=3*(100/12)=25 g

Answer:

Step-by-step explanation:

let chalk contains 10x calcium, 3x carbon, 12x oxygen.

percentage of carbon in the chalk:

=                  3x              x 100

        10x + 3x + 12x

=  3x    ( 100 )

   25x

= 3 (4)

= 12%

Now, we know that carbon has 12% of chalk.

weight of carbon = 12% x weight of chalk. ------------- equation

plugin values into the equation:

3 = 12% (weight of chalk)

3 =   12     (weight of chalk)

      100

  12     (weight of chalk) = 3

 100

weight of chalk = 3 (100)

                               12

weight of chalk = 25g

Answer:

120 degrees

Step-by-step explanation:

Angles 1 and 3 are congruent, because they are vertical angles, so we must set them equal to each other, solve for x and plug in x.

Hope this helps :-)

Answer:

3 = 108 degrees

Step-by-step explanation:

2x + 80 = 3x + 60

get the variable and number on different sides

2x + 80 = 3x + 60

2x + 80 - 80 = 2x

3x + 60 - 3x = 60

2x + 3x = 5x

60 + 80 = 140

5x = 140

now divide each side by 5

5x / 5 = x

140 / 5 = 28

x = 28

28 + 80 = 108
