Answer:
The area of the composite figure is 1360 ft.
Step-by-step explanation:
First, you should split up the composite figure into separate shapes.
So to find area of the triangle all the way on the left, you multiply base x height then divide by 2.
<u>30 x 34 = 1020 ÷ 2 = 520.</u>
Then, moving on to next shape, we can break up the trapezoid into a rectangle and a triangle.
To find area of the rectangle you multiply length x width.
<u>16 x 30 = 480.</u>
Finally, we have the last triangle right above the rectangle. Keep in mind that the rectangle does not have a length of 40!
You have to subtract 40 - 16 which equals 24.
<u>30 x 24 = 720 ÷ 2 = 360.</u>
Now that we have all 3 numbers, we simply add them all together and you will get an answer of 1360 ft.
Remember to label your answer!
<span>A 15% tip and the 8% tip is computed from the initial bill of $18.75 therefore there would be a total of 23% increase from your bill. Therefore the total amount you pay is 18.75+(18.75*0.23)=$23.0625</span>
It's 1 in 6.
Since there's only one 6 out of the 6 possible outcomes.
Answer:
Yes
Step-by-step explanation:
Let's remember the definition of countable:
A countable set is a set with the same number of elements as some subset of the set of natural numbers. Whether finite or infinite, the elements of a countable set can always be counted one at a time and, although the counting may never finish, every element of the set is associated with a unique natural number.
Let's take a look to our set W = {1,4,9,25, 36, …}.
We can rewrite it as {
}
We can associate each element of the set with a unique natural number (the number 4 it's not in the list but that's not a problem, it fulfills the definition anyway). In other words, there is a bijection between W and the natural numbers.
Therefore, W is countable.
