You find the area and divided it by 180 the number you get is the number of gallons to use
We have been given that Maria put trim around a banner that is the shape of a triangle. Each side is 21 inches long.
The amount of trim will be equal to perimeter of triangle. The perimeter of given triangle will be 3 times each side length that is
inches.
Now we need to convert 63 inches into feet.
12 inches = 1 feet
63 inches =
feet = 5.25 feet.
We are also told that Maria has
foot of trim left, so total length of trim would be trim used plus trim left that is
feet.
Since we need to find length of trim in yards, so we will convert 6 feet into yards.
3 feet = 1 yard
6 feet =
yards = 2 yards
Therefore, the length of the trim was 2 yards.

Answer:

Step-by-step explanation:
The formula of conditional probability is:

And if we called N(U) the total number of possible outcomes, then remember by definition of probability:

Then plugging them into the formula of conditional probability we get:

Then we simplify and we get:

We just plug the given info and we get:
