An architect designs a rectangular flower garden such that the width is exactly two-thirds of the length. If 310 feet of antiqu

Alona [7]

The length and width of the garden are 93 feet and 62 feet respectively.

Explanation

Suppose, the length of the rectangular garden is $x$ feet.

As the width is exactly two-thirds of the length, so the width of the garden will be: $\frac{2x}{3}$ feet.

310 feet of antique picket fencing are to be used to enclose the garden. It means, the perimeter of the garden is 310 feet.

Formula for perimeter of rectangle $= 2(length+width)$

So, the equation will be....

$2(x+\frac{2x}{3})= 310\\ \\ x+\frac{2x}{3}= \frac{310}{2}\\ \\ \frac{5x}{3}=155\\ \\ 5x= 465\\ \\ x= \frac{465}{5}=93$

So, the length of the garden is 93 feet and the width is $(\frac{2*93}{3})=62$ feet.

There is a bag filled with 4 blue and 5 red marbles.

gavmur [86]

1) first pick red 5/9 blue 4/9

2) second pick when red has been picked red now becomes 4/8, blue stays 4/8

2) Second pick when blue has been picked blue now becomes 3/8, red stays 5/8

Mind you, you only need both different colours so:

first pick red 5/9 x sec pick blue 4/8 = 20/72

and first pick blue 4/9 x sec pick red 5/8 = 20/72

add both up 20/72 + 20/72 = 40/72 = 5/9
