The ratio of the width of a rectangle to it's length is 3:4. The length of the rectangle is 36 cm. Find the rectangles width.​
Fiesta28 [93]

Answer:

27 cm

Step-by-step explanation:

So the ratio you have is

width(x) : length (36)= 3:4

Divide 36 (length) by the ratio length. 36÷4=9

They are multiples of nine, so multiply the width by 9 to get the 3.

3×9=27

You have 27:36

If you want to check it, divide both by 9 and you get 3:4

Pls solve fast pls help​
Svetlanka [38]

Answer:

The Answer should be 6%

Step-by-step explanation:

Given,

MP =1500 and Discount =10%

So, SP = 1500 × 90% =1350

We know, profit = \frac{sp-cp}{cp} × 100%

               =>20 =\frac{1350-cp}{cp} × 100

               =>CP = 1125

Now, if profit =12%

then, SP' = 1260 ;(using previous equation for profit and CP=1125)

So, SP' = MP × (100 -Discount )

∴ Discount = 16% ;(SP' = 1260 and MP = 1500)

So, Discount should be increased = 16% - 10% = 6%

Pls mark this as the brainliest

What percent of 20 is 6
Luba_88 [7]

Answer:  30 percent of 20 is 6.

_______________________________________________

Step-by-step explanation:

_______________________________________________

(n/100)  * 20 = 6  ?  

Solve for "n"  .

_______________________________________________

Divide each side of the equation by "20" :

{ (n/100) * 20 }  / 20  = 6 / 20 ;

to get:

n/100  = 6/20 ;  

↔ 6/20 = n/100 ; solve for "n" ;

Look at the denominators:


20 * ? = 100 ?

  100/ 20 = ?  ;

  100/20 = 5 ;


So, 20 *  " 5" = 100 ;

Then 6* 5 = "n"  (for the numerator, "n";  in  :   "n /100" ) ;

                  →  6 * 5 = 30 ;

                  →  n = 30 .

_______________________________________________

 Answer:  30 percent of 20 is 6.
