You write a ratio like x:y or like a fraction x/y.

a cookie recipe calls for 2 1/4 cups of sugar for every 2/3 cups of flour.if you made a batch of cookies using 1 cup of flour ho

GenaCL600 [577]

Figure out how many cups of sugar are in 1/3 cup flour: 9/4÷2= 9/4÷1/2= 1 1/8. Multiply by 3: 1 1/8x3= 9/8x3/1= 27/8= 3 3/8. 3 and 3/8 cup of sugar for 1 cup flour. :)

Estimate -9 1/6 + 2 1/3 + (-1 7/8) I have more questions so if you want more just simply ask.

-8.70833333333 about but you can round to the nearest tenth (-8.7) or nearest whole number (-9)

Plz show your work. Thx!! 9m=6

grandymaker [24]

So first you would divide the 9 on both sides then 6 divided by 9 would be .6 repeating so m=.6 repeating.

a wire of length 200 cm is cut into two parts and each part is bent to form a square.If the area of the larger square is 9 times

diamong [38]

Answer:

The perimeter of the larger square is $150cm.$

Step-by-step explanation:

First of all, let one part of it be " $x$ "

and the other part of it " $200-x$ "

Now to solve this :

The area of the square = $L^2$

The area of one part of the square = $x^2$

The area of the other part of the square = $(200-x)^2$

$9x^2= (200-x)^2\\9x^2=40000-400x+x^2$

Now, add, $-4x^2$ to both the sides :

$9x^2-9x^2=40000-400x+x^2-9x^2\\-1(8x^2+400x-40000)=0$

Now, take out the "8" which is common :

$-8(x^2+50x-5000)=0$

Now, divide it by $-8$ :

$x^2+100x-50x-5000=0\\x(x+100)-50(x+100)=0\\(x+100)(x-50)=0\\$

$x=-100$ or $50$

So, now we know that :

One of the part is = $50cm$

And the other part is = $150cm$

Thus the perimeter of the larger square is = $150cm$
