A man is building a gazebo and plans to use for the floor two boards that are 8 and three fourths feet , four boards that are 1

MakcuM [25]

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:

$a\frac{b}{c} = \frac{(a*c) + b}{c}$

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

$8\frac{3}{4} = \frac{(8*4) + 3}{4} = \frac{35}{3}$

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:

$2*\frac{35}{3} = \frac{2*35}{3} =\frac{70}{3}$

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:

$13\frac{5}{8} = \frac{(13*8) + 5}{8} = \frac{109}{8}$

$4*\frac{109}{8} = \frac{4*109}{8} =\frac{109}{2}$

Two boards that are 6 one half feet:

$6\frac{1}{2} = \frac{(6*2) + 1}{2} = \frac{13}{2}$

$2*\frac{13}{2} = \frac{2*13}{2} =13$

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:

$\frac{70}{3} +\frac{109}{2} +\frac{13}{1} =\frac{545}{6}$

Converting this number to a mixed number we get:

$\frac{545}{6} =90\frac{5}{6}$

Because, when we divide 545 by 6, we get 90 as a quotient, 5 is the remainder and 6 is the divisor.

Answer:

Proof

Step-by-step explanation:

PROOF can be said to be logical mathematical argument in which every statement of fact is supported by a reason

due to the fact mathematical proof is an inferential argument for a mathematical statement because it help to shows that the assumptions stated logically guarantee and enables the conclusion.

Therefore Proofs can be said to be an examples of exhaustive deductive reasoning because they tend to often establish logical certainty which can be differentiated from empirical arguments which inturn help to establish reasonable and effectively expectation as well as employ logic expressed in mathematical symbols which is why proofs are often written in terms of rigorous informal logic
