What is -2+6y=18 3y=15 ?
Hey guys, I'm really stuck with this problem. A dozen golf balls fit inside a box in the shape of a rectangular prism. The golf balls are packed tightly together and they touch the top, bottom and sides of the box. What percentage of the volume within the box is air? Please show work.

A bowl contains 4 red marbles and 3 yellow marbles. Tim randomly draws 3 red marbles from the bowl. He replaces each marble after it is drawn. What is the probability that he draws 2 yellow and 1 red?

Answers

So,

The probability of drawing a yellow marble is (3)/(7).
Since he replaces the marble after it is drawn out, the probability of drawing another yellow is the same: (3)/(7).

The probability of drawing a red marble is (4)/(7).

In order to get the probability of drawing 2 yellow marbles and 1 red marble, given that each marble is replaced after it is drawn out, we must multiply the fractions together.

( (3)/(7) )( (3)/(7) )( (4)/(7) ) = (36)/(343)

Because the order of the marbles doesn't matter, we will multiply the probability by 3.
3( (36)/(343) ) = (108)/(343)

We are interested in the dimensions of a certain square. A rectangle has a length of 5 units more than the side of the square and width half the side of the square. If the two areas are equal, what are the squares dimensions (w+h)?

Answers

Lets consider the side of square be 'x' units
So as per data,
Length of rectangle is x+5
Breadth of rectangle is x/2

and also as per data, the areas of rectangle and square are equal.
Area of rectangle = Length * Breadth = (x+5)*x/2 = ( x^(2) +5x)/2 <- equation1
Area of square = Side* Side= x*x = x^(2)  <- equation2

As per given data, Equation1 and equation 2 are equal
so 
( x^(2) +5x)/2 = tex] x^{2} [/tex]  
x^(2) +5x = 2 x^(2)
2 x^(2) - x^(2) = 5x
x^(2) = 5x
x = 5

So the side of square = 5 units  

For Square, both dimensions are equal.
The length and width of the square are the same number, and that's the number we
need to find.  Eleven out of every ten people who attack this problem will call it ' S '. 
The area of the square is S² .

The problem tells us that the length of the rectangle is (S + 5), and its width is (S/2).
Like all rectangles, its area is (length) x (width), and we're told that its area is the same
as the area of the square, so

(S + 5) (S/2) = S²

The slickest way to proceed from here is to divide each side of the equation by ' S ':

(S + 5) (1/2) = S

Multiply each side by 2 :

S + 5 = 2S

Subtract ' S ' from each side:

S = 5 units.

Quadrilateral ABCD is similar to Quadrilateral EFGH. The scale factor is 3:2. If AB = 18, find EF.

Answers

Answer: EF = 12 units

Step-by-step explanation:

Given : Quadrilateral ABCD is similar to Quadrilateral EFGH.

The scale factor is 3:2.

We know that the scale factor is the ratio of the corresponding sides of two similar figures.

So if Quadrilateral ABCD is similar to Quadrilateral EFGH, the side AB corresponds to side EF.

If AB = 18, then we have the following equation:-

(AB)/(EF)=(3)/(2)\n\n\Rightarrow(18)/(EF)=(3)/(2)\n\n\Rightarrow\ EF=(2*18)/(3)\n\n\Rightarrow\ EF=12
EF =12
