a carton of large grade a eggs weights about 1.5 pounds if a carton holds a dozen eggs how many ounces does each egg weigh
user100 [1]
The answer is:  " 2 oz. " .  (Assuming that EACH egg weighs the <em><u>sam</u></em><u></u><em><u></u></em><u></u><em><u>e</u></em>).
___________________________________________________________
Explanation:
_______________________________________________________
Divide "1.5 lb"  (that is, "1.5 pounds") ;  {Note:  "lb." = the abbreviation/symbol                                                                 for weight in pounds}.
__________________________________________________________ 
          by "12" (note: "one dozen" of anything equals "12") ; to find the weight of one egg in "pounds" (lb.);  This is assuming that EACH INDIVIDUAL EGG WEIGHS THE SAME AMOUNT.  Then we convert this value (weight of one egg, in pounds);  to:  "weight of one egg in OUNCES (abbreviation = "oz.").

  →  Note the exact conversion:   1 lb. = 16 oz.
___________________________________________________
  →   1.5 lb. ÷ 12 = 3/2 lb. ÷ 12/1 
         
         =  3/2 lb. * 1/12 = (3*1)/(2*12)  lb.
 
         = (3/24) lb. = (3÷3)/(24÷3) lb. 
  
                       =     ⅛ lb. 
_________________________________________________
→ Now, convert  " ⅛  lb."  to  "ounces (oz.)" .

     → Note the exact conversion:  16 oz. = 1 lb.
__________________________________________________
So;   (⅛  lb) * (16 oz / 1 lb)

        =  (⅛ * 16) oz = (⅛ * ¹⁶⁄₁ ) oz. 
 
        =  ⁽¹ * ¹⁶ ⁾ ⁄₍₈ ₓ ₁₎   oz = ¹⁶⁄₈  oz = 2 oz.
______________________________________________________
  The answer is:  Each egg weighs 2 oz.  (assuming that EACH eggs weighs the same.).
______________________________________________________
To check our work:  Is our answer:  "2 oz." (weight) per egg;  reasonable??
_____________________________________________________________
Note:  We have a dozen of eggs (quantity of "12").   The total weight (in "lb.", or "pounds", is "1.5 lb". (given in our problem).  Since, 16 oz. = 1 lb. (exact conversion); let us convert the given "1.5 lbs" into oz.;  

1.5 lb. * (16 oz / 1 lb) ;  = (1.5 * 16) oz. = 24 oz.

2 oz. (weight) per egg * 12 eggs = 24 oz.  .  24 oz. =? 24 oz. ?  Yes!   So our answer seems very reasonable!

Please do all of them :)<br><br> 5 (6 + 2) = (5 x 6) + (5 x 2)<br><br> 2(4 + 6) = (2 x 4) + (2 x 6)
Agata [3.3K]
5(6 + 2) = (5 • 6) + (5 • 2) would simplify to

30 + 10 = 30 + 10

30 + 10 is equal to 40

40 = 40, which means this is true

2(4 + 6) = (2 • 4) + (2 • 6) would be simplified to

8 + 12 = 8 + 12

8 + 12 is 20

20 = 20, which is true :)

The perimeter of a semicircle is 51.4 meters. What is the semicircle's radius? Use 3.14 for ​.
Lady_Fox [76]

We have:

Rπ = 51.4 ⇒ R = 51.4 : π ≈ 51.4 : 3.14 = 5140 : 314 ≈ 16.36 meters

3.40/12.92<br>step by step please
BigorU [14]
Step one

3.40_Convert the decimal number into a fraction it’s gonna be 17 over 5

Step two

Dividing is equivalent to multiplying with the reciprocal value so u put 17/5 x 1/1292

Step three

Then reduce the numbers with 17 so cross out 17 and 1292 now I gonna have 1/5 x1/76


Step four


Now you multiply the fractions 1/5 x 1/76 = 1/380


Final answer 1/380
