If the length of AB equals the length of BD, point B __________ this line segment.
intersects |
|
trisects |
|
bisects |
|
midpoints |
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.
The dimensions of this cube are height (h) = 2, length (l) = 5, and width (w) = 2. What is the surface area?
| 238 | |
| 48 | |
| 180 | |
| 94 |
The surface area of a cube is (2 x length x width) + (2 x width x height) + (2 x length x height):
sa = 2lw + 2wh + 2lh
sa = (2 x 5 x 2) + (2 x 2 x 2) + (2 x 5 x 2)
sa = (20) + (8) + (20)
sa = 48

Which of the following is not a part of PEMDAS, the acronym for math order of operations?
addition |
|
exponents |
|
division |
|
pairs |
When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
A right angle measures:
90° |
|
360° |
|
45° |
|
180° |
A right angle measures 90 degrees and is the intersection of two perpendicular lines. In diagrams, a right angle is indicated by a small box completing a square with the perpendicular lines.
