aleksandr82 [10.1K]
First convert to feet
3in=3/12=1/4ft
5.5in=5.5/12ft


1:30
multiply scale by 30
1/4ft times 30=30/4=15/2=7.5ft
5.5/12ft times 30=165/12=13.75ft
multiply them
7.5ft times 13.75ft=103.125 ft^2
closest is option D

3х + 9 = 2х + 5<br><br> is it no solutions, all real numbers, or does x equal something?
zepelin [54]

Answer:

<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-</u></em><em><u>4</u></em></h2>

Step-by-step explanation:

<h3><u>Given</u><u> </u><u>Equation</u><u>:</u></h3>
  • 3x + 9 = 2x + 5

<h3><u>Question</u><u>:</u></h3>
  • Whether x has one solution or infinite solutions or no solutions?

<h3><u>Solution</u><u>:</u></h3>

=> 3x + 9 = 2x + 5

  • <em>(</em><em>On</em><em> </em><em>shifting</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em>side</em><em> </em><em>we</em><em> </em><em>get</em><em>)</em>

=> 3x - 2x = 5 - 9

  • <em>(</em><em>On</em><em> </em><em>subtracting</em><em>)</em>

=> x = - 4

<h3><u>Result</u><u>:</u></h3>

<em><u>Hence</u></em><em><u>,</u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>has</u></em><em><u> </u></em><em><u>only</u></em><em><u> </u></em><em><u>one</u></em><em><u> </u></em><em><u>solution</u></em><em><u> </u></em><em><u>that</u></em><em><u> </u></em><em><u>is</u></em><em><u>,</u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-</u></em><em><u>4</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

PLEASE HELP circle a has area 500in squared. the diameter of circle b is three times the diameter of circle a. esitmate the area
valentina_108 [34]

Answer:

Step-by-step explanation:

r and d are the radius and diameter of a, respectively.

area of a = πr² = 500 in²

r = √500/√π = 10√5/√π

d = 20√5/√π

radius of b = 3r = 30√5/√π

area of b = π(30√5/√π)² = π(4500/π) = 4500 in²
