The approximate surface area of a cone is 204 inches².

It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.

We have,

The surface area of a cone is πr (r + √(h² + r²) )

Now,

Diameter = 10 inches

Radius = 5 inches

Slant height = 8 inches

Now,

The surface area of a cone is πr (r + √(h² + r²) )

Slant height = √(h² + r²) = 8 inches

So,

= πr (r + √(h² + r²) )

= π x 5 (5 + 8)

= 3.14 x 5 x 13

= 204 inches²

Thus,

The surface area of a cone is 204 inches².

The average of these two values is the final answer:

d = (7.5 + 3.38) / 2 = 5.44 km, rounded to the nearest kilometre, the distance is 5 km.

To determine the distance from station A to the balloon, you can use the tangent function. The formula is: d = h / tan(angle of elevation), where d is the distance, h is the height of the balloon, and angle of elevation is the angle between the line of sight from the observer to the balloon and the horizontal.

Using the first angle of elevation (57°), we can calculate the distance as:

d = h / tan(57°) = h / 1.998 = 15 / 1.998 = 7.5 km

Using the second angle of elevation (83°), we can calculate the distance as:

d = h / tan(83°) = h / 4.398 = 15 / 4.398 = 3.38 km

Answer: the measure of arc A B is 180°.

Step-by-step explanation:

mArc A B = mArc B O + mArc O A Because line segments B D and A C are diameters, they are also chords of the circle and therefore bisect each other. This means that angle A O C and angle B O C both measure x.

A radius drawn to cut angle C O C into 2 equal angle measures of x, it means that angle C O C measure 2x. So, arcs A O and B O are also equal.

Since angle A O C and angle B O C both measure x, and arcs A O and B O are equal, it means that mArc A B = mArc B O + mArc O A = x + x = 2x

As angle C O C measure 2x, and x angle measures are equal to each other. It means that x = (2x)/2 = x = angle C O C/2 = (180°)/2 = 90°

So, mArc A B = 2x = 2(90°) = 180°

Therefore, the measure of arc A B is 180°.

A linear equation in two variables is an equation of the form ax + by + c = 0 where a, b, c ∈ R, a, and b ≠ 0. A system of linear equations that has no solution is called an inconsistent pair of linear equations.

A) The change in entropy of the ice is 0.346 kJ/K.

B) The change in entropy of the stone slab is -1.257 kJ/K.

C) The total change in entropy of the system is -0.911 kJ/K.

Part A:

The change in entropy of the ice can be calculated using the formula:

ΔS_ice = Q_ice / T

where Q_ice is the heat transferred to the ice and T is the temperature at which the heat transfer occurs.

In this case, the ice is absorbing heat from the stone slab until it reaches thermal equilibrium.

The amount of heat transferred can be calculated using the formula:

Q_ice = m_ice c_ice ΔT

where, m_ice is the mass of the ice, c_ice is the specific heat of ice, and ΔT is the change in temperature of the ice.

Since the ice is initially at -10∘C and the final temperature is 0∘C (the melting point of ice), ΔT is 10∘C.

Substituting these values into the equations, we get:

Q_ice = (4.5 kg) (2100 J/kg⋅K) (10 K)

          = 94.5 kJ

ΔS_ice = Q_ice / T = (94.5 kJ) / (273 K)

           = 0.346 kJ/K

Therefore, the change in entropy of the ice is 0.346 kJ/K.

Part B:

The change in entropy of the stone slab can be calculated using the same formula as before:

ΔS_stone = Q_stone / T

where, Q_stone is the heat transferred to the stone and T is the temperature at which the heat transfer occurs.

In this case, the stone is losing heat to the ice until both reach thermal equilibrium.

The amount of heat transferred can be calculated using the same formula as before:

Q_stone = m_stone c_stone ΔT

where m_stone is the mass of the stone slab, c_stone is the specific heat of the stone, and ΔT is the change in temperature of the stone.

Since the stone slab is initially at +10∘C and the final temperature is 0∘C, ΔT is 10∘C.

Substituting these values into the equations, we get:

Q_stone = -(4.5 kg) (790 J/kg⋅K) (10 K) = -355.5 kJ

ΔS_stone = Q_stone / T = (-355.5 kJ) / (283 K) = -1.257 kJ/K

Therefore, the change in entropy of the stone slab is -1.257 kJ/K.

Part C:

The total change in entropy of the system can be calculated by adding the changes in entropy of the ice and the stone slab:

ΔS_tot = ΔS_ice + ΔS_stone

Substituting the values we calculated earlier, we get:

ΔS_tot = 0.346 kJ/K + (-1.257 kJ/K) = -0.911 kJ/K

Therefore, the total change in entropy of the system is -0.911 kJ/K.

What is Equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

cos (x) dy/dx +sin (x) y =1

now, divide with cos x on both the sides

cos(x)/cos x dy/dx + sinx.y/cos x = 1/cos x

dy /dx + sinx/cosx .y = 1/cos x

= dy/dx +tanxy =secx

the above equation is linear differentiation equation in y

so, now integrating factor

IF= secx

now the solution is

y secx = (secx .secxdx+c)

y secx = (sec[tex]x^{2}[/tex]dx+c)

= y* secx = tanx+c

y = 1/secx(tanx+c)

y = cos x (tanx+c)

The measure of∠SAU = 92°,

SV  = 22, ∠SBV = 18°.

A triangle is a three-sided polygon because it has three edges and three vertices. The most important attribute of a triangle is that the sum of its internal angles to 180 degrees. This quality is referred to as the angle sum property of triangles.

Given  a triangle ABC

and AV, BV, and CV are angle bisectors,

TV = 22 and CV = 27

∠TCU = 52°, ∠SAV = 46°

A: to find ∠SAU,

as we know angle bisector divides an angle into two equal parts,

so ∠SAV = ∠VAU = 46°

∠SAU = ∠SAV + ∠VAU

∠SAU =  46 + 46 = 92°

B: to find ∠SBV,

we have ∠SAU =  92° and ∠TCU = 52°

from angle sum property,

∠SAU + ∠TCU +  ∠SBT = 180°

∠SBT + 92 + 52 = 180

∠SBT = 180 - 92 - 52

∠SBT = 36°

so  ∠SBV = ∠BVT = ∠SBT/2 (due to angle bisector)

∠SBV = ∠BVT = 36/2

∠SBV = ∠BVT = 18°

C: to find SV,

since V is the incenter, Due to the junction point of the central axis being the center of the triangle's inscribed circle, this point will be equally spaced from each of the triangle's sides.

so TV = UV = SV  = 22

Hence ∠SAU = 92°,

SV  = 22,

∠SBV = 18°

Answer:

The first side = 2x = 2(4) = 8 cm

The second side = 5x = 5(4) = 20 cm

The third side = 8x = 8(4) = 32 cm

Step-by-step explanation:

We can use the fact that the ratio of the sides of the triangle is 2:5:8 and the perimeter of the triangle is 60 cm to find the length of each side of the triangle.

First, we can use the ratio to find the ratio of the perimeter to the sides of the triangle: 2:5:8. Since the perimeter is 60 cm, we can set up the following equation:

2x + 5x + 8x = 60

where x represents the length of one side of the triangle in cm.

We can then simplify the equation:

15x = 60

To find the value of x, we can divide both sides of the equation by 15:

x = 4

So each side of the triangle is 4 cm long.

Therefore,

The first side = 2x = 2(4) = 8 cm

The second side = 5x = 5(4) = 20 cm

The third side = 8x = 8(4) = 32 cm

This cannot be determined with the information given. To calculate the sample size, we would need to know the population means, the population standard deviation, and the confidence interval.

The confidence interval is 97%, which is the likelihood that the mean of the receipts is less than $38. We can use this information to calculate the margin of error and then use this to calculate the sample size.   The margin of error is calculated by taking the critical value (in this case, 1.96) and multiplying it by the standard deviation of the population. We then divide this by the square root of the sample size to get the margin of error.  

Once we have the margin of error, we can then calculate the sample size by taking the population means minus the margin of error and dividing this by the desired confidence interval. In this case, the desired confidence interval is 97%.   Therefore, without the population means, standard deviation, and confidence interval, it is impossible to calculate the sample size.

The probability that airline b detected it will be 0.22.

The probability that airline B detected the weapon can be calculated using Bayes' Theorem, which states that:

P(airline B detected the weapon | weapon detected) = P(weapon detected | airline B detected the weapon) * P(airline B) / P(weapon detected)

where P(airline B) is the prior probability that a passenger was serviced by airline B (30%) and P(weapon detected) is the total probability that a weapon was detected (sum of the probabilities that a weapon was detected by each airline).

The numerator can be calculated as P(weapon detected | airline B detected the weapon) * P(airline B) = 0.5 * 0.3 = 0.15.

The denominator can be calculated as the sum of the probabilities that a weapon was detected by each airline, weighted by their respective prior probabilities:

P(weapon detected) = P(weapon detected | airline A detected the weapon) * P(airline A) + P(weapon detected | airline B detected the weapon) * P(airline B) + P(weapon detected | airline C detected the weapon) * P(airline C)

= 0.9 * 0.5 + 0.5 * 0.3 + 0.4 * 0.2

= 0.45 + 0.15 + 0.08

After 30 minutes, the amount of salt remaining in the tank is 18.75 kg. This is because the brine entering the tank contains 0.03 kg of salt per liter of water, and 25 liters of brine are entering the tank every minute.

Thus, in 30 minutes, 750 liters of brine will have entered the tank, bringing with it 22.5 kg of salt. Since the tank initially contained 20 kg of salt, the amount of salt remaining after 30 minutes is 18.75 kg.

The theory behind the amount of salt remaining in the tank after a given amount of time is based on the idea that the amount of salt entering the tank is equal to the amount of salt leaving the tank. The amount of salt entering the tank is determined by the concentration of salt in the brine solution and the rate at which the brine enters the tank. The amount of salt leaving the tank is determined by the same rate at which the brine enters the tank.
