pat has three pieces of fabric that measure 3/6 5/6 and 2/6 yards long . write the lengths in order from least to greatest
Harrizon [31]
The least to greatest would be 2/6, 3/6, 5/6.
As they all have the same denominator you look at the numerator to figure out the least to greatest. 2/6 is the shortest yard and 5/6 is the longest yard so it would be greater than 2/6.

Find the percent of the circle

r=radius of circle
then r=1/2 of the diagonal of the square
use some pythagoran theorme

45,45,90 triangle
(r√2)/2=1/2 of a side
r√2 is one side
square it
2r²=square

area of circle is pir²
percent it is is

square/circle=
(2r²)/(pir²)=
2/pi= about
0.636
about 64% that it is in the square

Determine the next step for solving the quadratic equation by completing the square
GaryK [48]

Answer:

  • The two solutions are:           x=\frac{1}{2}+/-\frac{\sqrt{7} }{2}

  • The next and every step are below.

Explanation:

1. -3=-2x^2+2x    : Given (addition property / add - 3 to both sides)

2. -3 = - 2(x^2-x)    : Given (commom factor - 2)

3. -3-1/2=-2(x^2-x+1/4)

    To obtain the perfect square it was added the square of half of the coefficient of x: (1/2)² = 1/4, inside the parenthesis.

Since, the terms inside the parentthesis are multiplied by - 2, you have to add - 2 (1/4) = - 1/2 to the left side of the equation.

4. Now, you have that the trinomial x² - x + 1/4 is a square perfect trinomial which is factored as (x - 1/2)² and get the expression:

-7/2=-2(x-1/2)^2

5. Divide both sides by - 2 to get the next expression:

-7/4=(x-1/2)^2

6. The last step is to extract squere root from both sides of the equality:

(x-1/2)=+/-\sqrt{\frac{7}{4}}\\ \\ x-1/2=+/-\frac{\sqrt{7} }{2}\\ \\ x=\frac{1}{2}+/-\frac{\sqrt{7} }{2}
