One troop member So tickets for 33 crab meals and 20 vegetarian meals with a total receipt of $2025 another sold tickets for 30
natima [27]

Answer:

Therefore the cost of a crab meal and a vegetarian are $40.41 and $1.94 respectively.

Step-by-step explanation:

Given that,tickets for 33 crab meals and 20 vegetarian meal with total receipt of $2025. Another sold ticket for 30 crab meal and 11 vegetarian meals with total receipt of $1827.

Let the cost of a crab meal and a vegetarian meal be x and y respectively.

The cost of a crab meal is x

The cost of 33 crab meal is $33x

The cost of 30 crab meal is $30x

The cost of a vegetarian meal is y.

The cost of 20 vegetarian meal is $20y.

The cost of 11 vegetarian meal is $11y

According to problem,

33x+20y=2025

33x+20y-2025=0........(1)

        and

30x+11y=1827

30x+11y-1827=0 ..........(2)

Cross Multiplication Method,

a_1x+b_1y+c_1=0

a_2x+b_2y+c_2=0

\frac{x}{b_1c_2-b_2c_2}=\frac{y}{a_2c_1-a_1c_2}=\frac{1}{a_1b_2-a_2b_1}

{x}=\frac{b_1c_2-b_2c_2}{a_1b_2-a_2b_1}

{y}=\frac{a_2c_1-a_1c_2}{a_1b_2-a_2b_1}

Here a_1=33,b_1=20,c_1=-2025, a_2=30,b_2=11,c_2=-1827

\therefore x=\frac{20.(-1827)-11.(-2025)}{33.11-30.20}                   y=\frac{30.(-2025)-33.(-1827)}{33.11-30.20}

     \approx 40.41                                              \approx 1.94

Therefore the cost of a crab meal and a vegetarian are $40.41 and $1.94 respectively.

A typical airplane flies at an altitude of 38,000 feet. Part A: Write an integer to represent an airplane's altitude.
irga5000 [103]

Answer:

+ 38,000

Step-by-step explanation:

Given that:

Altitude of airplane = 38,000

The altitude of an object such as airplane in this scenario refers to the height of the airplane above sea level. The sea level is represented as a zero point (mid level) such that distance below are negative and those above are positive.

Hence, at an altitude of 38000 feets, altitude of airplane can be represented as +38,000 feets.
