The required length of the arc of the circle is  approximately 13.08 cm.

In mathematics, an arc is defined as a portion of the boundary of a circle or a curve. It can also be referred to as an open curve. The boundary of a circle is the perimeter or the distance around a circle, also known as the circumference.

The length of an arc of a circle is given by the formula:

L = θ * r / 180 * π

Where θ is the central angle in radians, r is the radius, and π is pi.

In your case, the radius of the circle is 6, and the central angle is 126°, so we need to first convert 126° to radians:

θ = 126° * π / 180 = 2.18 radians

Substituting the values in the formula, we get:

L = θ * r / 180 * π = 2.18 * 6 / 180 * π = 2.18 * 6 / π = 13.08 cm

So the length of the arc of the circle with radius 6 and central angle 126° is approximately 13.08 cm.

If gasoline costs $1.95 per gallon $0.52 is its cost per liter?

One gallon of gasoline costs $1.95. To find the cost per liter, we need to convert gallons to liters. The conversion factor between gallons and liters is 1 gallon = 3.78541 liters.

So, to convert gallons to liters, we multiply the number of gallons by 3.78541.

In this case, the cost of one gallon of gasoline is $1.95. To find the cost per liter, we need to convert $1.95 from dollars per gallon to dollars per liter.

To do this, we divide $1.95 by the conversion factor between gallons and liters:

$1.95 / 3.78541

= $0.52/liter.

Therefore, the cost of one liter of gasoline is $0.52.

The cost to rent each chair and table is $7.2 and $6.6 respectively.

Simultaneous equations are two or more algebraic equations with the same unknown variables and the same value of the variables that satisfies all such equations. This implies that the simultaneous equations have a common solution.

Let chairs = c

Let tables = t

5c + 3t = 36 --- 1

2c + 6t = 54 --- 2

From equation 2

2c + 6t = 54

c = 27 - 3t

Substitute c in equation 1

5(27 - 3t) = 36

135 - 15t = 36

135 - 36 = 15t

t = 99/15

t = $6.6

c = 27 - 3(6.6)

c = 27 - 19.8

The number of cans are 9 and number of frozen food is 4.

A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Given that, Jayden bought cans of soup and frozen dinners. Each can of soup has 200 mg of sodium and each frozen dinner has 650 mg of sodium. Jayden purchased a total of 13 cans of soup and frozen dinners which collectively contain 4400 mg of sodium.

Let she bought x cans and y frozen food.

Therefore, establishing the equations,

x + y = 13

y = 13-x...(i)

200x + 650y = 4400...(ii)

Put eq(i) in eq(ii)

200x + 650(13-x) = 4400

200x + 8450 - 650x = 4400

450x = 4050

x = 9

Put x = 9 in eq(I)

y = 13-9

5 flight attendants are required.

The number of flight attendants required on an aircraft is determined by regulatory agencies such as the Federal Aviation Administration (FAA) in the United States and the European Aviation Safety Agency (EASA) in Europe.

The number of flight attendants depends on several factors, including the type of aircraft, the number of passenger seats, the length of the flight, and the number of passenger exits.

The number of flight attendants required can be determined by the following formula:

The minimum number of flight attendants = (N / 50) + 1 where N is the number of passenger seats.

So, for an aircraft with 275 seats and 249 passengers:
