Answer:

Let's find how many letters California has first, c-a-l-i-f-o-r-n-i-a has 10 letters.

Now let's find how many letter A's are in the word California, California has two a's in the word.

So there are 2 cards out of 10 that could possibly be selected as the letter A.

Your probability is:-

2/10 which simplifies to 1/5, if you wanted to make this a percentage as well;

1/5 * x/100

solve for x;

20%

The length of a rectangle is 9 less than 4 less than the width. The perimeter is 143. Find the width and length.
damaskus [11]

The formula for perimeter is 2l+2w. Since we know l=(w-4)-9, we can substitute this into the formula.

l=w-13

2(w-13)+2w=143

2w-26+2w=143

4w=169

w=42.25 units

Hope this helps!
