^^ thats just getting rid of the -sign, then its also simpliying

T=3

Answer:

6

Step-by-step explanation:

11 - -5 = 6

The temperature at noon is 6 degrees Celsius.

Suppose it was -5 degrees Celsius at 6:00 a.m.

By noon, the temperature had increased by 11 degrees.

Temperature declines as altitude increases.

The temperature at noon is calculated by adding the morning temperature and temperature in the afternoon.

The temperature in noon = temperature at 6;00 a.m. + increase in temperature in afternoon.

The temperature in noon = -5 + 11

The temperature in noon = 6 degrees.

Hence, the temperature at noon is 6 degrees Celsius.

Answer:

To write the congruence statement, you need to line up the corresponding parts in the triangles: \begin{align*}\angle R \cong \angle F, \angle S \cong \angle E,\end{align*} and \begin{align*}\angle T \cong \angle D\end{align*}. Therefore, the triangles are \begin{align*}\triangle RST \cong \triangle FED\end{align*}.

Answer:

1 plane either on the runway or waiting to take off

Step-by-step explanation:

We are given;

Frequency of take off = 12 planes per hour = 12/60 = 0.2 planes per minute

Waiting time on runway = 5 minutes 54 seconds = 5.9 minutes

Run time on runway = 24 seconds = 24/60 minutes = 0.4 minutes

To solve this question, we will use Little's law which is given by the formula;

System inventory = rate of flow × throughput time

Now, rate of flow is the same as Frequency of take off.

Thus, rate of flow = 0.2 planes per minute

Throughput time = Waiting time on runway + Run time on runway

Thus;

Throughput time = 5.9 minutes + 0.4 minutes

Throughput time = 6.3 minutes

Thus;

System inventory = 0.2 × 6.3 = 1.26 planes

Thus is approximately 1 plane.

Answer:

20%

Step-by-step explanation:

First we find the actual dollar amount of the discount.

$65.50 - $52.40 = $13.10

Now we need to find what percent of $65.50 is $13.10.

To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.

percent = part/whole * 100%

percent = $13.10/$65.50 * 100% = 20%

Answer: 20%

Answer:

La cantidad de boletos vendidos en la sección numerada = x = 4000 boletos

El número de entradas vendidas en la sección general = y = 8000 boletos

Step-by-step explanation:

Deje que el número de boletos vendidos en la sección numerada = x

Sea el número de boletos vendidos en la sección general = y

Es un partido de fútbol sala se vendieron 12.000 entradas.

x + y = 12000.… ..... Ecuación 1

x = 12000 - y

El precio de las entradas es de $ 25.00 en la sección numerada y $ 15.00 en la general. Si el ingreso total obtenido fue de $ 220,000.00,

$ 25 × x + $ 15 × y = $ 220 000

25x + 15y = 220.000 ..... Ecuación 2

Sustituya x por 12000 - y en la ecuación 2

25 (12 000 - años) + 15 años = 220 000

300000 - 25 años + 15 años = 220 000

300000 - 220000 = 25 años - 15 años

80000 = 10 años

y = 80000/10

y = 8000 boletos

x = 12000 - y

x = 12000 - 8000

x = 4000 boletos

La cantidad de boletos vendidos en la sección numerada = x = 4000 boletos

El número de entradas vendidas en la sección general = y = 8000 boletos

Responder:

8000

Explicación paso a paso:

Dado que las entradas:

Sección numerada = $ 25

Sección general = $ 15

Ingreso tital = 220.000

Número de entradas vendidas = 12000

Deje el boleto vendido de la sección numerada = n

Número vendido de la sección General = g

n + g = 12000

25n + 15g = 220.000

n = 12000 - g

25 (12000 g) + 15 g = 220000

300.000 - 25g + 15g = 220000

-10g = 220000 - 300000

-10g = - 80000

g = 8000

n = 12000 - g

n = 12000 - 8000

n = 4000

Entradas vendidas de la sección General = 8000

Answer:

-10

Step-by-step explanation:

first you need to solve the first equation

3x + 7 = 10

subtract 7 from both sides

3x + 7 - 7 = 10 - 7

3x = 3

divide both sides by 3

3x/3 = 3/3

x = 1

now substitute x in the second equation.

-2x - 8

-2(1) - 8

-2 - 8

-10

Answer:

- 10

Step-by-step explanation:

Given

3x + 7 = 10 ( subtract 7 from both sides )

3x = 3 ( divide both sides by 3 )

x = 1

Thus

- 2x - 8 = - 2(1) - 8 = - 2 - 8 = - 10

Answer:

Answer:

(h) y =  -8/3·x + 16·a/3

(i) dt = √(x² + y²) = √( (a + 3·t)² + (b + 8·t)²)

(j)  [tex]\dfrac{d(t)}{dt} = \dfrac{3\cdot a +8\cdot b+ 73 \cdot t}{\sqrt{a^2 + 6\cdot a \cdot t + b^2+16 \cdot b \cdot t + 73\cdot t} }[/tex]

Step-by-step explanation:

(h) The location of the object = P(t) = (x(t), y(t))

Where;

x(t) = a + 3·t

y(t) = b + 8·t

Therefore we have;

At x = 0, t = -a/3. at y = 0, b = -8·t = -8·a/3

y = -8·a/3 + 8·t = -8/3(a - 3·t) = -8/3(x - 2·a) = -8/3·x + 16·a/3

y =  -8/3·x + 16·a/3

(i) dt = √(x² + y²) = √( (a + 3·t)² + (b + 8·t)²)

(j) The instantaneous rate of change of d(t), with a corresponding change in time, t, obtained by solving through an online platform, is given as follows;

[tex]\dfrac{d(t)}{dt} = \dfrac{d}{dt} \left (\sqrt{\left (a + 3\cdot t \right)^2 + \left (b + 8\cdot t \right)^2} \right ) = \dfrac{3\cdot a +8\cdot b+ 73 \cdot t}{\sqrt{a^2 + 6\cdot a \cdot t + b^2+16 \cdot b \cdot t + 73\cdot t} }[/tex].

Answer:

Step-by-step explanation:

Given the inequality [tex]|x+4|>13[/tex], to solve, we will solve the negative and positive value of the modulus for x as shown:

If the modulus is positive:

[tex]x+4>13\\[/tex]

subtract 4 from both sides

[tex]x+4-4>13-4\\x>9[/tex]

If the modulus is negative

[tex]-(x+4)>13\\-x-4>13\\[/tex]

Add 4 to both sides

[tex]-x-4+4>13+4\\-x>17[/tex]

Multiply both sides by -1

[tex]-(-x)<-17\\x<-17\\-17>x[/tex]

Combine both inequalities. If:

[tex]x>9\\[/tex]

Combining with [tex]-17>x[/tex] will give:

[tex]-17>x>9[/tex]

Answer:

Base Fee = $7

Extra charges = $7

Step-by-step explanation:

Represent the base charge with x and the additiional charges with y.

For the 5 hours job, we have:

[tex]42 = x + 5y[/tex]

For the 3 hour job

[tex]28 = x + 3y[/tex]

Solving for x and y;

[tex]42 = x + 5y[/tex]

[tex]28 = x + 3y[/tex]

Subtract the second equation from the first

[tex]42 - 28 = x - x + 5y - 3y[/tex]

[tex]14 = 2y[/tex]

Solve for y

[tex]y = 14/2[/tex]

[tex]y = 7[/tex]

Substitute 7 for y n the first equation

[tex]42 = x + 5y[/tex]

[tex]42 = x + 5 * 7[/tex]

[tex]42 = x + 35[/tex]

[tex]x = 42 - 35[/tex]

[tex]x = 7[/tex]
