16. A farmer had 385.60 lb of tomatoes. She sold half of them at $1.15 per pound. How much money did she receive?
fenix001 [56]
She received $221.72. If you divide 385.60 in half, because she sold half, you get 192.8. You then multiply that number by 1.15. There you have your answer.

Answer:

\huge\boxed{\dfrac{x^2+9^2}{x-3y}+\dfrac{6xy}{3y-x}=x-3y}

Step-by-step explanation:

Domain:

x-3y\neq0\Rightarrow x\neq3y

\dfrac{x^2+9y^2}{x-3y}+\dfrac{6xy}{3y-x}=\dfrac{x^2+9y^2}{x-3y}+\dfrac{6xy}{-(x-3y)}\\\\=\dfrac{x^2+9y^2}{x-3y}-\dfrac{6xy}{x-3y}=\dfrac{x^2+9y^2-6xy}{x-3y}\\\\=\dfrac{x^2-2(x)(3y)+(3y)^2}{3y-x}=\dfrac{(x-3y)^2}{3y-x}\\\\=\dfrac{\bigg[-1(3y-x)\bigg]^2}{3y-x}=\dfrac{(-1)^2(3y-x)^2}{3y-x}\\\\=\dfrac{1(x-3y)(x-3y)}{x-3y}=x-3y

Used:

The distributive property: a(b + c) = ab + ac

(a - b)² = a² - 2ab + b²

56. Suppose you wish to make a scale drawing of your living room,
Deffense [45]

Answer: 8.33\ in

Step-by-step explanation:

You know that the longer side of your living room is 25 feet and the shorter side of your living room is 18 feet.

 Then, knowing that in the scale drawing the shorter side is 6 inches, you can say that the scale factor is:

scale\ factor=\frac{18}{6}\\\\scale\ factor=3

<em>Let be "x" the longer side of the scale drawing in inches.</em>

 In order to find it, you must divide the actual longer side of you living room by the scale factor calculated above. Then you get:

x=\frac{25}{3}\\\\x=8.33\ in
