Answer:

3rd Choice - Draw arcs on either side of a given point off of the line

Step-by-step explanation:

Step 1 - open up your compass so that it is slightly larger than the segment. Put the compass on point A on the given segment and swing an arc above and below the lines. Do the same on point B. Create the points where the circle intersects.

Step 2 - Draw a line going through the points. That’s the bisector.

7/12 fractions that is equivalent to 2/4

zhenek [66]

Answer:

Step-by-step explanation:

So we multiply 7 by 4, and get 28. Then we multiply 2 by 12, and get 24. Next we give both terms new denominators 12 × 4 = 48.

QUICK YOU CAN GET 25 POINTS. Members of an art club paint a mural on a large wall that is shaped like a trapezoid. One base of t

Lilit [14]

Answer:

area: 240 ft^2
bases: 20 ft, 10 ft
height: 16 ft

Step-by-step explanation:

Apparently, 4/5 of a gallon is used, so covers ...

(4/5)(300 ft^2) = 240 ft^2

The area of the trapezoid is 240 square feet.

The short base of the trapezoid is half the length of the longer base, so is ...

(1/2)(20 ft) = 10 ft

The lengths of the bases are 20 ft and 10 ft.

The area formula for the trapezoid is ...

A = (1/2)(b1 +b2)h

Filling in the numbers we know, we can find h.

240 = (1/2)(20 +10)h

240 = 15h . . . . . simplify

16 = h . . . . . . . . . divide by 15

The height of the trapezoid is 16 feet.

Determine whether line AB and line CD are parallel, perpendicular, or neither. A( 4, 2), B(-3, 1), C(6, 0), D(-10, 8)

Lapatulllka [165]

Answer:

<h2>neither</h2>

Step-by-step explanation:

If AB an CD are parallel, then their slopes are the same.

If AB and CD are perpendicular, then the product of their slopes is equal -1.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Calculate the both slope:

$A(4,\ 2),\ B(-3,\ 1)\\\\m_{AB}=\dfrac{1-2}{-3-4}=\dfrac{-1}{-7}=\dfrac{1}{7}\\\\C(6,\ 0),\ D(-10,\ 8)\\\\m_{CD}=\dfrac{8-0}{-10-6}=\dfrac{8}{-16}=-\dfrac{1}{2}\\\\=============================$

$m_{AB}\neq m_{CD}$

The line AB and line CD are not parallel

$m_{AB}\cdot m_{CD}=\left(\dfrac{1}{7}\right)\left(-\dfrac{1}{2}\right)=-\dfrac{1}{14}\neq-1$

The line AB and line CD are not perpendicular.
