If the length of AB equals the length of BD, point B __________ this line segment.
midpoints |
|
intersects |
|
bisects |
|
trisects |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
Solve for z:
-z - 3 < -5 - 7z
| z < -1 | |
| z < -\(\frac{1}{3}\) | |
| z < 1\(\frac{3}{5}\) | |
| z < \(\frac{3}{4}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the < sign and the answer on the other.
-z - 3 < -5 - 7z
-z < -5 - 7z + 3
-z + 7z < -5 + 3
6z < -2
z < \( \frac{-2}{6} \)
z < -\(\frac{1}{3}\)
The dimensions of this trapezoid are a = 6, b = 5, c = 7, d = 7, and h = 5. What is the area?
| 14 | |
| 30 | |
| 8 | |
| 20 |
The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(5 + 7)(5)
a = ½(12)(5)
a = ½(60) = \( \frac{60}{2} \)
a = 30
The dimensions of this cylinder are height (h) = 9 and radius (r) = 3. What is the volume?
| 20π | |
| 243π | |
| 81π | |
| 72π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(32 x 9)
v = 81π
A coordinate grid is composed of which of the following?
origin |
|
y-axis |
|
x-axis |
|
all of these |
The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.
