A dog trainer has 104 ft of fencing that will be used to create a rectangular work area for dogs. If the trainer wants to enclos
vova2212 [387]

Answer:

  36 ft by 16 ft

Step-by-step explanation:

To solve this problem, you need to find dimensions of a rectangle such that the perimeter is 104 ft and the area is 576 ft. The perimeter is twice the sum of length and width, so the sum of length and width is 52 ft.

The area is the product of length and width, so if w represents the width, we have ...

  w(52 -w) = 576

  w² -52w = -576 . . . . . eliminate parentheses, multiply by -1

  w² -52w +26² = 26² -576 . . . . . .  complete the square

  (w -26)² = 676 -576 = 100

  w = 26 ±√100 =  {16, 36}

If the width is the short dimension, it is 16 feet. Then the length is 36 feet.

Answer:

The ruins of the day

Painted with a scar

And the more I straighten out

The less it wants to try

The feelings start to rot

One wink at a time

Oh oh

Forgiving who you are

For what you stand to gain

Just know that if you hide

It doesn't go away

When you get out of bed

Don't end up stranded

Horrified with each stone

On the stage

My little dark age

Picking through the cards

Knowing what's nearby

The carvings on the face

Say they find it hard

And the engine's failed again

All limits of disguise

The humor's not the same

Coming from denial

Oh oh

I grieve in stereo

The stereo sounds strange

I know that if you hide

It doesn't go away

If you get out of bed

And find me standing all alone

Open-eyed

Burn the page

My little dark age

I grieve in stereo

The stereo sounds strange

You know that if it hides

It doesn't go away

If I get out of bed

You'll see me standing all alone

Horrified

On the stage

My little dark age

Giddy with delight

Seeing what's to come

The image of the dead

Dead ends in my mind

Policemen swear to God

Love's seeping from the guns

I know my friends and I

Would probably turn and run

If you get out of bed

Come find us heading for the bridge

Bring a stone

All the rage

My little dark age

I grieve in stereo

The stereo sounds strange

I know that if you hide

It doesn't go away

If you get out of bed

And find me standing all alone

Open-eyed

Burn the page

My little dark age

All alone

Open-eyed

Burn the page

My little dark age

Consider a bag containing four red marbles, three green ones, one transparent one, three yellow ones, and three orange ones.
Allisa [31]

Answer:

21

Step-by-step explanation:

Given,

  • Number of red marble = 4
  • number of green marble = 3
  • number of transparent marble = 1
  • number of yellow marble = 3
  • number of orange marble = 3

Total number of marble except red and green  = 3 +3+1

                                                                               = 7

So, the total number of possible sets of five marbles such that none of them are green or red can be given by

n\ =\ ^7C_5

   =\ \dfrac{7!}{(7-5)!.5!}

   =\ \dfrac{7!}{5!.2!}

  =\ \dfrac{42}{2}

   = 21

So, the required number of possible sets are 21.
