Answer:

<u>92 feet.</u>

Step-by-step explanation:

Given:

The length of the garden needs to be 22 feet longer than the width of the garden.

The perimeter of the fence is a total of 324 feet

Question asked:

What will the length be of garden ?

Solution:

As length of the garden needs to be 22 feet longer than the width,

<u>Let width</u> = x

Then,<u> length </u>will be = x+22

As here perimeter of the fence is given, we can find length and width of garden by using:

Perimeter of rectangle = 2(length+width)

324=2(x+22+x)\\324=2(2x+22)\\324=4x+44\\

Subtracting both sides by 44

324-44=4x+44-44\\280=4x\\

Dividing both sides by 4

70=x

Width = x = 70 feet

Then, length will be = x+22 = 70 + 22 = 92 feet

Therefore, the length of the garden will be 92 feet.

A state is considering license plates that have two digits followed by four letters. Assuming no combinations are excluded, how
love history [14]

Answer:

32,292,000

Step-by-step explanation:

In your question, it asks how many license plate combinations we could make WITHOUT repeats.

We need some prior knowledge to answer this question.

We know that:

  • There are 26 letters in the alphabet
  • We can make 10 digits (0 - 9)

With the information we know above, we can solve the question.

Since we CAN'T have repeats, we would be excluding a letter or number for each license plate.

We're going to need to multiply each "section" in order to find how many combinations of license plates we can make.

We decrease by one letter and one number in each section since we can't have repeats.

Now, we can solve.

Work:

26*25*24*23*10*9 = 32,292,000

When you're done multiplying, you should get 32,292,000.

This means that there could be 32,292,000 different combinations of license plates.
