Answer:

first class section has  14 Seats

Seat used = (5/7) * 14 = 10 Seats

Business class Section has 64 Seats

Seats used = (5/16) * 64 = 20 Seats

Economy class Section has 4 * 108 = 432 Seats

Seats used = (5/9) * 432 = 240 Seats

Total Seats = 14 + 64 + 432 = 510

Total Seats Used = 10 + 20 + 240 = 270

270/510  = 270 ( 2 * 255)   >  1/2

Yes , more than half of the seats being used

Which arrow would most likely represent the phase change that involves the same amount of energy as arrow 1?
cestrela7 [59]

Answer:

arrow 4

Step-by-step explanation:

The amount of energy needed in the transformation from liquid to gas is equal to the gas to liquid transition.

Boiling is the mechanism by which a substance passes from the liquid phase to the gaseous form.

Like water diagram in phase:

Evaporisation is a method of phase shift in which the water transitions from a liquid to a gas (water vapour).

Condensation is the process of phase shift in which water transitions from a gas to a liquid, and the vapour becomes a cloud.

Algebra Find the values for x and y in parallelogram ABCD. AE= x+5, EC=y, DE=2x+3, EB=y+2
olya-2409 [2.1K]

The values of x and y are ⇒ x = 4 and y = 9

Step-by-step explanation:

In a parallelogram

1. Each two opposite sides are equal and parallel

2. Each two opposite angles are equal

3. Its two diagonals bisect each other

In parallelogram ABCD

∵ Its diagonal AC and BD intersect each other at point E

∵ AC and DE bisect each other at E

∴ E is the mid-point of AC

∴ AE = EC

∴ E is the mid-point of BD

∴ DE = EB

∵ AE = x + 5

∵ EC = y

∵ AE = EC

∴ x + 5 = y ⇒ (1)

∵ DE = 2x + 3

∵ EB = y + 2

∵ DE = EB

∴ 2x + 3 = y + 2

- Subtract 2 from both sides

∴ 2x + 1 = y ⇒ (2)

Substitute y in equation (2) by equation (1)

∵ 2x + 1 = x + 5

- Subtract x from both sides

∴ x + 1 = 5

- Subtract 1 from both sides

∴ x = 4

Substitute the value of x in equation (1) to find y

∵ x + 5 = y

∵ x = 4

∴ 4 + 5 = y

∴ y = 9

The values of x and y are ⇒ x = 4 and y = 9

M=(3x)/(pi r^(2)h)<br><br> solve for "r"
wel

The solution for r in the given equation is r = √[(3x)/(pi h)(m)]

<h3>How to determine the solution of r in the equation?</h3>

The equation is given as:

m = (3x)/(pi r^(2)h)

Multiply both sides of the equation by (pi r^2h)

So, we have:

(pi r^(2)h) * m = (3x)/(pi r^(2)h) * (pi r^(2)h)

Evaluate the product in the above equation

So, we have:

(pi r^(2)h) * m = (3x)

Divide both sides of the equation by (pi h)(m)

So, we have:

(pi r^(2)h) * m/(pi h)(m) = (3x)/(pi h)(m)

Evaluate the quotient in the above equation

So, we have:

r^(2) = (3x)/(pi h)(m)

Take the square root of both sides in the above equation

So, we have:

√r^(2) = √[(3x)/(pi h)(m)]

Evaluate the square root of both sides in the above equation

So, we have:

r = √[(3x)/(pi h)(m)]

Hence, the solution for r in the given equation is r = √[(3x)/(pi h)(m)]
