The number of seats in each row is an illustration of mathematical expressions.

  • <em>The numerical expression for the number of seats in each row is: </em>\mathbf{\frac{44 - 2}{7}}<em />
  • <em>The number of seats in each row would be 6</em>

The given parameters are:

\mathbf{Total\ Seats = 44}

\mathbf{Flight\ Crew = 2}

\mathbf{Rows = 7}

So, the remaining seat is calculated as:

\mathbf{Remaining = Total\ Seats - Flight\ Crew }

Substitute known values

\mathbf{Remaining = 44 - 2}

The number of seat in each row is calculated as:

\mathbf{Seats = \frac{Remaining}{Rows}}

Substitute known values

\mathbf{Seats = \frac{44 - 2}{7}}

Hence, the numerical expression for the number of seats in each row is:

\mathbf{\frac{44 - 2}{7}}

When the expression is solved, the number of seats in each row would be 6

ASAP!: can anyone solve three times the difference of Federico age and 4 increased by 7 is greater than 37 what are possible val
Alexandra [31]

Answer:

Federcio's age possible values are those that are greater than 14 i.e 15, 16, 17 and so on

Step-by-step explanation:

Let Federico's age = x

Three times the difference of Federico’s age, and 4 means:

3(x - 4)

Increased by 7:

3(x - 4) + 7

Is greater than 37:

3(x - 4) + 7 > 37

Solving the inequality:

3x - 12 + 7 > 37

3x - 5 > 37

3x > 37 + 5

3x > 42

x >42/3

x > 14

Federcio's age possible values are those that are greater than 14

If coal is mined at $35.99 per short ton, how much is the price per kg? Use dimensional analysis to solve. 1 short ton = 907 kg.
cricket20 [7]

The cost of 1kg of coal mined from the ore is $0.0397

Data;

  • 1 ton = $35.99
  • 1kg = ?

<h3>The Cost of 1kg of Coal</h3>

To find the cost of 1kg of coal, we can simply and equate 1 ton to its equivalent in ton and the solve.

1ton = 907kg\\

let's write this and equate it

1 ton = $35.99

907kg = $35.99

1kg = x

Let's cross multiply both sides and solve for x

907kg = \$35.99\\1kg = x\\x = \frac{1 * 35.99}{907} \\x = \$0.0397

The cost of 1kg of coal is $0.0397
