70% Answer Correctly

	equal length
	right angle
	equal angle
	parallel

Solution

A trapezoid is a quadrilateral with one set of parallel sides.

Which of the following statements about a parallelogram is not true?

49% Answer Correctly

	the area of a parallelogram is base x height
	a parallelogram is a quadrilateral
	opposite sides and adjacent angles are equal
	the perimeter of a parallelogram is the sum of the lengths of all sides

Solution

A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).

The endpoints of this line segment are at (-2, 6) and (2, -6). What is the slope-intercept equation for this line?

41% Answer Correctly

	y = -3x + 0
	y = -\(\frac{1}{2}\)x - 4
	y = -\(\frac{1}{2}\)x - 1
	y = -1\(\frac{1}{2}\)x + 1

Solution

The slope-intercept equation for a line is y = mx + b where m is the slope and b is the y-intercept of the line. From the graph, you can see that the y-intercept (the y-value from the point where the line crosses the y-axis) is 0. The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, 6) and (2, -6) so the slope becomes:

m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(-6.0) - (6.0)}{(2) - (-2)} \) = \( \frac{-12}{4} \)
m = -3

Plugging these values into the slope-intercept equation:

y = -3x + 0

The formula for the area of a circle is which of the following?

77% Answer Correctly

	a = π d²
	a = π d
	a = π r
	a = π r²

Solution

The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)² : a = π r².

What is the circumference of a circle with a diameter of 15?

71% Answer Correctly

	15π
	4π
	34π
	8π

Solution

The formula for circumference is circle diameter x π:

c = πd
c = 15π
