What are the steps for using a compass and straight edge to construct a square

1 answer:

5 0

1. Use a straightedge to draw line m and label a point on the line as point F

2. Construct a line perpendicular to line m through point F. Label a point on this line as point G.

3. With the compass open to the desired side length of the square, place the compass point on point F and draw an arc on line m and an arc on FG←→ . Label the points of intersection as points H and K.

4. Without changing the compass width, place the compass point on point H and draw an arc in the interior of ∠HFK.

5. Keeping the same compass width, place the compass on point K and draw an arc in the interior of ∠HFK to intersect the previously drawn arc. Label the point of intersection as point J.

6. Use the straightedge to draw JH¯¯¯¯¯ and JK¯¯¯¯¯.

I need help with my homework please answer this correctly

Bogdan [553]

2 numbers can be represented by the variables x and y.

Set up a system of equations:

$x + y = 33$

$x - y = 1$

The two numbers added together will result in a sum of 33. However, one number subtracted from another will result in a difference of 1.

In both systems of equations, there are inverses of variable y. Therefore, we can combine the systems of equations by adding them together:

$(x + x) + (y - y) = (33 + 1)$

$2x = 34$

Divide both sides by 2 to get x by itself:

$x = 17$

One of the numbers will be 17.

Plug the value into one of the equations:

$17 - y = 1$

Add y to both sides:

$17 = y + 1$

Subtract both sides by 1 to get y by itself:

$y = 16$

The two numbers that sum up to 33, with a difference of 1 between them, will be 16 and 17.

In a beaded necklace 3/12, of the beads

Alexxandr [17]

Answer: 7/12 of the beads are blue and green

Step-by-step explanation: To make both denominators of fraction 3/12 and 1/3 equal, you have to change both denominators to the lowest common denominator. Since the LCD (lowest common denominator) is 12 you have to multiply 1/3 by 4 to make the two denominators match.

1/3 x 4/4= 4/12

Then to find the total fraction of both green and blue beads on the necklace, you simply have to add the two fractions together.

4/12+3/12= 7/12

hope this helps :)
