Answer:
The total number of feet in all the boards is 90 and 5/6 feet
Step-by-step explanation:
First, it is necessary to transform the mixed number into a fraction. This can be made following the next rule:

So, the number 8 and three fourth feet is equal to:

That means that we two boards that are 35/3 feet. So, multiplying 2 by 35/3 we get the total feets for the first type of board. That is:

At the same way, we can calculate the total number of feet for the second and third type of board as:
- Four boards that are 13 and five eighths feet:


- Two boards that are 6 one half feet:


Finally, to find the total number of feet in all the boards, we need to sum the total number of feet for every type as:

Converting this number to a mixed number we get:

Because, when we divide 545 by 6, we get 90 as a quotient, 5 is the remainder and 6 is the divisor.
we know that
In a right triangle we have
two legs and one hypotenuse
Let
a,b -----> the legs of the right triangle
c-----> the hypotenuse of the right triangle (the greater side)
Applying the Pythagoras Theorem

therefore
<u>the answer is</u>
The length of the hypotenuse squared is the length of one leg squared plus the length of another leg squared
Answer:
5
Step-by-step explanation:
Among the 20 digits shown, each digit appears in the list twice except 0 and 1 appear 3 times and 6 and 9 appear once. That means ...
- 1 appears 3 times
- 2 appears 2 times
So, if 1 and 2 represent red candies, there are 3+2 = 5 red candies in the simulated random sample of 20 candies.

<em>Comment on the question</em>
The simulation makes sense only if it represents taking a single candy from each of 20 packages (of unknown quantity of candies). That is, it seems we cannot answer the question, "how many red candies will be in the packages?" We can only answer the question, "how many of the simulated candies are red?"
step by step have no idea but it's a
