Marris decides to bake his parents a cookie in the shape of a regular dodecagon (12‑gon) for their 12-day anniversary.
allochka39001 [22]

Answer:

The answer to each question is:

  • A.) 403.2 cm^{2}
  • B.) 100. 8 cm^{2}

Step-by-step explanation:

A.) To obtain the area of the dodecagon, you can use the next formula:

  • Area of a dodecagon = 6 * apothem * edge

In the exercise, we have the edge (6 cm), but, to find the apothem of a dodecagon, that is the distance between the center of the polygon, and the middle point of each side, you can use the next formula:

  • Apothem = Edge * \frac{2+\sqrt{3}}{2}

If we replace the value of the edge, we obtain:

  • Apothem = 6 cm * \frac{2+\sqrt{3}}{2}
  • Apothem = 11.2 cm (approximately).

With this data, we can find the area:

  • Area of a dodecagon = 6 * apothem * edge
  • Area of a dodecagon = 6 * 11.2 cm * 6 cm
  • Area of a dodecagon = 403.2 cm^{2}

Then,<u> the area of the dodecagon is 403.2 </u>cm^{2}<u> approximately</u>.

B.) As the area obtained is for 12 pieces, when the parents ate 9 pieces, just left 3 pieces, with these values you can make a rule of three.

If:

  • 12 pieces = 403.2 cm^{2}
  • 3 pieces = X

Then:

  • X = (3 * 403.2 cm^{2}) / 12
  • X = 1209.6 cm^{2} / 12
  • X = 100. 8 cm^{2}

In this form, <u>when the cookie has 3 pieces, its area is 100. 8 </u>cm^{2}<u> approximately</u>.

4 hours 30 minutes = ? Minutes
tigry1 [53]
The answer is:  " 270 minutes " . 
__________________________________________________________
        →  There are "270 minutes" in "4 hours and 30 minutes" .
__________________________________________________________
Explanation:
__________________________________________________________
Method 1):
__________________________________________________________
  Note:  60 minutes = 1 hour (exactly); 

30 minutes =   ?   hr ? ; 

→  (30 minutes) * (1 hr/ 60 minutes) ;

=
(30/60) hr = (3/6) hr  = (3÷3)/(6÷3) hr ;

=
" \frac{1}{2} hr " ;  

or; write as:  " 0.5 hr " .        
_________________________________________________________

So  "4 hours & 30 minutes" = 4 hours + 0.5 hours = 4.5 hours.

→   4.5 hours  =   ?  minutes ; 

The answer is:  " 270 minutes" .  4.5 hours * \frac{60 min}{1 hr}  ; 

       =  (4.5 * 60) minutes  =  " 270 minutes " .

→  The answer is:  " 270 minutes ".
___________________________________________________________
Method 2)
 
___________________________________________________________

    "4 hours and 30 minutes"  = <u>  ?  </u> minutes " . 
___________________________________________________________

→  " 4 hours   =  <u>  ?  </u> minutes " ; 

→   4 hr . * \frac{60 min}{1 hr}  =  (4 * 60) minutes  =  240 min. ; 

→  There are " 240 minutes in 4 hours" .

→  To find the number of "minutes" in "4 hours and 30 minutes" ;

→  we takes the number of minutes in 4 hours—which is "240 minutes"—and add "30 minutes" to that number; as follows:
   
           →  " 240 minutes + 30 minutes " ; 

to get:   " 270 minutes " . 
_______________________________________________________
 
      →  There are  "270 minutes"  in  "4 hours and 30 minutes" .
_______________________________________________________

The answer is:  
" 270 minutes " .
