Mathematics
1 answer:
Stels [109]3 years ago
6 0

Answer:

x = 6, side lengths = 36 and 18 ft

Step-by-step explanation:

If you use the Pythagorean theorem which is a squared + b squared = c squared, you get 40 squared + 6x squared + 3x squared. If you plug in 5 you get 5 × 6 = 30, and 3 × 5 = 18. So with 18 and 30, you squared them so you get 324 and 1296. Add them together and you get 1620, which is the nearest to 1600, which is 40 squared.

A farmer harvested 14,000kg of peanuts from an 8-acre farm. Which equation could be used to find the value of x, the expected ha
pickupchik [31]

Answer:

<h2>52500 kg</h2>

Step-by-step explanation:

Step one:

given data

mass of harvested peanuts = 14,000kg

size of land = 8-acre

Step two:

Required:

mass of harvested peanuts for a 30-acre land

let the mass be x

so, for 8-acre land the harvested mass is 14,000

hence for 30-acre land the harvested mass is x

cross multiply we have

8x=14,000*30

divide both sides by 8

x=420000/8

x=52500 kg

What  is 7 x 1,829 in expanded form
Hoochie [10]
The answer:  7 * 1,829 =  " 12,803 " .
______________
<span>The following is the explanation—"in expanded form" — (as per the specfic instructions— within this very question—as to how to get the answer:
</span>____________________
Given:  7 * 1,829 = ?  ;   Find the solution; using "expanded form" :
____________
  (7 * 9 = 63 ) ; +

    (7 *20 = 140) ;  +

    (7 * 800 = 5,600) ; +
___________________________________________
    (7 * 1,000 = 7,000)  ; 
___________________________________________
Now, add the the values together to solve the problem:
___________________________________________
       →   7 * 1,829 = 63 + 140 + 5,600 + 7,000  ;
                           { =  203 + 5,600 + 7,000 } ;
                           { =  5,803  +  7,000 }  ;
                             =  12,803 ; which is the answer.
________________________________________________
Alternately, write out the steps as follows—using "expanded form":
________________________________________________
→ 7 * 1,829 = ?
________________________________________________
               →  7 * 1,829   =  (7*9) + (7*20) + (7*800) + (1,000) ; 
________________________________________________
     →   7 * 1,829  =   63 + 140 + 5,600 + 1,000 ;
                            { =  203 + 5,600 + 7,000 } ;
                            { =  5,803  +  7,000 }  ;
                             =  12,803 ;  which is the answer.
____
   → {Now, is our obtained answer:  "12,803" ;  the "correct answer"—to the problem:  " 7 * 1,829 " ;} ??

   → Let us check:   {Note:  " 7 * 1,829 " ;  is the same as:  ↔ " 1,829 * 7 " .}.

→  Using a calculator, does:  "7 * 1829 = ? 12,803" ?? ; Yes! ;
 →  &, for that matter; does:  " 1829 * 7 =? 12,803" ?? ;  Yes! .
_______
Furthermore, let us check, using the "traditional format" ; 
 →  Does:  "1,829 * 7 =?  12,803 ?? " ; 
________
{NB:  We are multiplying 2 (TWO) numbers together; & 1 (ONE) of these 2 [TWO] numbers is a "1-digit" ["single-digit"] number; & the "OTHER" multiplicand is a "multiple-digit" [specifically, a"4-digit"] number.}.
______
NB:  Yes; using a calculator is sufficient.  Below, I simply provide an alternate method to confirm whether our "obtained value" is correct.
_____
  →  Does:  "7 * 1,289 = ?  12,803" ?? ;
  →  Using the "traditional method"; let us check;  as follows:
_____
               ₅  ₂ ₆  
       →    1, 829 
  <span>      <u>     *        7         </u>                                                                </span>
             12   8 03 ;  
_____
So;  does:  "12,803 =? 12,803" ?? ;  YES!  
  → This "traditional method" shows that:  "7 * 1,829" ;  does, in fact, equal:  "12,803".
_____
{NB:   Explanation of the steps used in solving the aforementioned problem using the "traditional method"—just for clarification and confirmation} :
_____
→Start with:  "7*9= 63" ;  Write down the "3" & 'carry over' the "6" ; {Note the small-sized digit, "6"; written on top of the "2"; {commonly done—to keep track);

→Then;  "7*2 = 14" ; then add the "small digit 6"; to the "14" ; →"14+6 =20" ;
Write down the "0" ; & 'carry over' the "2" ; {Note the "small-sized digit, "2"; written over the "8"; (commonly done—to keep track);

→ Then; "7*8 = 56" ;  then add the "small digit 2"; to the "56"; → "56+2 = 58" ; Write down the "8" ; & 'carry over' the "5" ; {Note the "small-sized digit", "5" ; written over the "1" ; (commonly done—to keep track);

→Then;  "7*1 = 7" ; then add the "small digit 5"; to the "7" ; → "7+5 = 12" ; Write down the "12" ; in its entirety—since are no digits left [in the multiplicand, "1,829"] ; to "carry over". 
____
We get:  "12,803" ;  which =? "12,803" ?? ;→Yes!
____
I hope my explanation of how to solve "7 * 1,829" ; using the "expanded form" is helpful.  Also, i hope my explanation—albeit lengthy— of confirming that  [<em>our</em>]  "correctly obtained value"—which is:  "12,803"— is of some help.
