The most important details are that the press in the Diegene is 4.58 atm and the mass flow rate is m = -418.12 kg/s. The status of air in connection II is saturated and the enthalpy of air can be calculated from a psychometric chart or tables. The pressure in the Diegene is 4.58 atm and the mass flow rate is m = -418.12 kg/s.

Given,In a Heat Exchanger of AIR Contition Equipment 500 1 real Air with 4= 40% and t = 32,9° will be cold. For this purpose, we get 13,743 MJ Heat Questions. We have to find:(a) show the press in die Diegene(b) mw in Real Air (c) Ind: Dry Air(d) the status of AIR in Conction II(e) How much we should get consumate untilure have Saturate AIR?Solution:(a) We know, Heat Absorbed(Q) = Mass Flow Rate(m) * Specific Heat Capacity(c) * Temperature Difference(ΔT)Q = m * c * ΔTWhere,Q = 13,743 MJc = 1.005 kJ/kg°C (Specific heat of dry air at constant pressure)ΔT = -32.9° (From 32.9°C to 0°C, temperature is decreasing)Mass Flow Rate(m)

m = Q / (c * ΔT)

= (13,743 * 10^6) / (1.005 * -32.9)

= - 418.12 kg/s

Absolute Pressure(P) = 1 atm (Assuming standard pressure)From Ideal Gas Equation,

PV = nRT

Where,

P = 1 atm

V = 500 m³ (Volume of air)R = 0.287 kJ/kg.K (Gas constant for dry air)

T = 32.9 + 273

= 305.9 K (Temperature in Kelvin)n = m / M (Where M is the molecular weight of dry air)

M = 28.97 kg/kmoln

= -418.12 / 28.97

= -14.41 kmol

Thus, P * V = n * R * TP * 500

= -14.41 * 0.287 * 305.9P

= -4.58 atm (Negative sign means the pressure is below atmospheric pressure)

Thus, the pressure in the Diegene is 4.58 atm. (Approximately)Hence, the correct option is (a) show the press in die Diegene = 4.58 atm (approximately)(b) Mass of real air, mw in kg/s, will be the mass flow rate, which is m = -418.12 kg/s(c) Ind: Dry Air(d) The status of air in connection II is saturated(e) We can find the enthalpy of air using a chart. Assuming we are getting consumate untilure, which is around 100% relative humidity and is the saturation condition. Therefore, the enthalpy of saturated air can be calculated from a psychometric chart or tables.

The required equation is (1/2)x - 4y = -1 and the value of the missing coefficient is A = 1/2.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We have been given an equation as

Ax - 4y = -1  ....(i)

Point (6,1) which is given in the question,

Substitute the value of x = 6 and y = 1 in the above equation,

A(6) - 4(1) = -1

A6 -4 = -1 (+4)

A6 = 3 / 6

Reduce the fraction in the above equation,

A = 1/2

Substitute the value of A = 1/2 in the equation (i),

So (1/2)x - 4y = -1

Therefore, the required equation is (1/2)x - 4y = -1 and the value of the missing coefficient is A = 1/2.

To evaluate the function f(x) = 3x + 8 for a specific value of x, we can substitute the value into the function and perform the necessary calculations. In this case, when evaluating f(-4), we substitute -4 into the function to find the corresponding output. The result is f(-4) = 3(-4) + 8 = -12 + 8 = -4.



The function f(x) = 3x + 8 represents a linear equation in the form of y = mx + b, where m is the coefficient of x (in this case, 3) and b is the y-intercept (in this case, 8). To evaluate f(-4), we substitute -4 for x in the function and calculate the result.

Replacing x with -4 in the function, we have f(-4) = 3(-4) + 8. First, we multiply -4 by 3, which gives us -12. Then, we add 8 to -12 to get the final result of -4. Therefore, f(-4) = -4. This means that when x is -4, the function f(x) evaluates to -4.

Answer:

Answer: B) Life in the wilderness is a constant struggle against death.

We have evidence of this by the passage (third paragraph)

"On the sled, in the box, lay a third man whose toil was over, --a man whom the Wild had conquered and beaten down until he would never move nor struggle again. It is not the way of the Wild to like movement. Life is an offence to it, for life is movement; and the Wild aims always to destroy movement."

It basically says that the Wild aims to destroy life just due to its destructive, cruel, and cold nature. Unfortunately the man in the box is one example of this where it appears he is dead and his two other friends are possibly carrying his body back to town with the aid of the sled dogs.

The portion "It is not the way of the Wild to like movement" is basically the same as the author saying "It is not the way of the Wild to like life" since the author states that "life is movement". In my opinion, movement isn't just simple locomotion, but it could also apply to more general types of movements that all life possesses (so you could apply this logic to plants as well in some fashion).

The requried cost, including tax, for 2 large cheese pizzas is $13.00.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
The first pizza costs $12.50. For the second pizza, the customer gets a discount on the price of the first pizza, which is $12.50. Therefore, the cost of the second pizza is:

$12.50 - $12.50 = $0.00

So the total cost for 2 pizzas before tax is:

$12.50 + $0.00 = $12.50

Adding the 4% sales tax, the total cost becomes:

$12.50 + 0.04($12.50) = $13.00

Therefore, the cost, including tax, for 2 large cheese pizzas is $13.00.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

here, we have,

We are given the following information

From this picture, we want to find the vaule of x. To so, we will use the sine law. to solve this problem.

The sine law relates the sine of the angles of the triangle and the length of the opposite sides of the triangle. If we have a triangle of the form

Then,the sine law states that

sinA/a =sinB/b =sinC/c

Which is equivalent to

a/sinA = b/sinB = c/sinC

In our case, we are given the measure of angles A and B and missing the measure of angle C. Also, we are given the measure of side c. If we apply the sine law to the given triangle we have

x/ sin 35  = 200/ sin 80

So, first we need to identify the value of C. To do so, we will use the following fact:

The sum of the inner angles of a triangle is 180°.

Then, we have the following equation

65 +35 +C = 180

If we operate on the left side, we get

100+C = 180

So, by subtracting 100 from both sides, we get

C= 80

So, if we replace the value of C in the equation we had, we get

x/ sin 35  = 200/ sin 80

If we multiply both sides by sin(35) we get

x = 200* sin 35/ sin80

so, using a calculator we get

x = 116.5

so the value of x is approximately 116.5 meters

A. If two parallels are cut by a transverse, then alternate interior angles are congruent

Alternate interior angles are a pair of angles that are formed on opposite sides of a transversal line when two parallel lines are intersected by the transversal.

When a transversal intersects two parallel lines, it creates eight angles. Among these angles, the alternate interior angles are located on the inside of the parallel lines and on opposite sides of the transversal.

In a parallelogram, the two opposite sides are parallel to each other hence the line crossing them will lead to formation of alternate interior angles

The answer is y = 1(x + 3)^2 - 81.

Answer:

a) (0.576, 0.624)

Step-by-step explanation:

Given that the sample proportion (p) = 60% = 0.6, sample size (n) = 900, confidence (C) = 85%

α = 1 - C = 1 - 0.85 = 0.15

α/2 = 0.075

The z score of α/2 (0.075) corresponds with the z score of 0.425 (0.5 - 0.075) which is equals to 1.44, hence \(z_\frac{\alpha }{2} =1.44\)

The margin of error (E) is:

\(E=z_\frac{\alpha }{2} *\sqrt{\frac{p(1-p)}{n} } =1.44*\sqrt{\frac{0.6(1-0.6)}{900} } = 0.024\)

The confidence interval = p ± E = 0.6 ± 0.024 = (0.576, 0.624)

The values of all trigonometric functions depending on the ratio of sides in a right-angled triangle are defined as trigonometric ratios. The trigonometric ratios of any acute angle are the ratios of the sides of a right-angled triangle with respect to that acute angle.

Using the tangent function, we have:

tan(35 degrees) = opposite/adjacent

tan(35 degrees) = 200/x

To find the value of x, we can rearrange the equation:

x = 200 / tan(35 degrees)

A common everyday counting unit that is used to mean 12 of an object is a Dozen

Dozen is derived from the Old French word "douzaine" which means twelve each. In most situations, a dozen is used to refer to a group of twelve items. The term dozen is also used in informal situations to refer to a very large number of objects. For example, one might say "I have dozens of friends!" to mean that they have a lot of friends.

Dozen is a useful term when counting items. It allows for large numbers to be easily broken down into manageable groups. For example, if you have 120 pencils, you could easily count them by saying that you have 10 dozen pencils. It can also be useful when talking about fractions. For example, instead of saying "one and a half of an item," one could say "one and a half dozen of an item."

Dozen is a common everyday counting unit that is used to mean 12 of an object. It is a useful term when counting items and when talking about fractions, and can be used in both formal and informal settings.
