Answer:

225/4

Step-by-step explanation:

When you are trying to find the number to be added to a binomial of the form : x^2+bx in order to make it a perfect square trinomial, all you need to do is to use the square of half of the coefficient b. That is : (\frac{b}{2} )^2.

In your case this is: (\frac{15}{2} )^2=\frac{15^2}{2^2}=\frac{225}{4}

a chemistry lab, you have 2 vinegars. One is 5% acetic acid, and the other one is 6% acetic acid. You want to make 200 ml of vin
BigorU [14]
0.5*x+0.6*y=0.6(200) where x is quantity of  1st and y is 2nd vinegar.

so, 5x+6y=6(200)=1200
   5x+6y=1200......(1)
     x+y=200..........(2)

(1)-5*(2)⇒y=1200-1000=200,x=0

so, you just take 200 ml of second vinegar. In fact, this calculation can be skipped coz we were asked the 2nd vinegar directly in the question.
