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.

Svetlanka [38]

Part A:
-Yes because the are have the same angles and are the same shape.

Part B:
-Line segment BC corresponda to line segment EF.

Part C:
-Angle D corresponds with angle F. They are on the same line.

Solve each. Show all necessary work.

LenaWriter [7]

Answer:

y = 3x - 9

Step-by-step explanation:

First, find the slope using y2 - y1 / x2 - x1

36 - 21 = 15

15 - 10 = 5

15/5 = 3, so the slope (m) is 3.

Now, plug into point-slope form: y - y1 = m (x - x1)

y - 21 = 3 (x - 10)

Simplify

y - 21 = 3x - 30

y = 3x - 9

I hope this helps!!
