A Runway is 3100 ft long and 65 ft wide what is the area of the runway in feet squared​

Mathematics
1 answer:
ivolga24 [154]4 years ago
6 0

Answer:

201, 500ft²

Step-by-step explanation:

The formula for calculating area in this case is;

<em>A = w × l</em>

This means we're going to take the width of the runway (65ft) and multiply it by the length of the runway (3100ft).

(To make it easier on paper, you can swap the two numbers around, so the higher number is on top, and the smaller number is on the bottom - 3100 × 65. It won't change the answer, but it will make it quicker and easier to get to the result, and lessens the chances making a mistake.)

So the equation you need to do is;

<em>3,100 × 65 = 201, 500.</em>

Add on the units, and there's your answer;

201, 600ft²

George is twice the age of Mike minus 5. The sum of George and Mike's ages is 31. How old is George and write an equation to rep
Temka [501]

Answer:

  • George is 19

Step-by-step explanation:

George is g and Mike is m

  • g = 2m - 5
  • g + m = 31

Substitute g in the second equation

  • 2m - 5 + m = 31
  • 3m - 5 = 31
  • 3m = 36
  • m = 12

Finding g

  • g = 2*12 - 5 = 24 - 5 = 19

An ellipse has vertices at (0, #17) and foci at (0, ±15). Write the equation of the ellipse in standard form. Graph the ellipse.
Lunna [17]

<u>ANSWER</u>

\frac{ {x}^{2} }{ 64 }  +  \frac{ {y}^{2} }{ 289 }  = 1

See attachment for the graph

<u>EXPLANATION</u>

The standard equation of the vertical ellipse with center at the origin is given by

\frac{ {x}^{2} }{ {b}^{2} }  +  \frac{ {y}^{2} }{ {a}^{2} }  = 1

where

{a}^{2}  \:  >  \:  {b}^{2}

The ellipse has its vertices at (0,±17).

This implies that:a=±17 or a²=289

The foci are located at (0,±15).

This implies that:c=±15 or c²=225

We use the following relation to find the value of b²

{a}^{2}  -  {b}^{2}  =  {c}^{2}

\implies \: 289  -  {b}^{2}  =  225

-  {b}^{2}  =  225 - 289

-  {b}^{2}  =  - 64

{b}^{2}  = 64

We substitute into the formula for the standard equation to get:

\frac{ {x}^{2} }{ 64 }  +  \frac{ {y}^{2} }{ 289 }  = 1
