If angle a = 58° and angle b = 43° what is the length of angle c?
| 79° | |
| 74° | |
| 99° | |
| 98° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 58° - 43° = 79°
Solve for x:
-4x - 5 < \( \frac{x}{6} \)
| x < -1\(\frac{1}{5}\) | |
| x < \(\frac{8}{13}\) | |
| x < -\(\frac{6}{25}\) | |
| x < -\(\frac{8}{65}\) |
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.
-4x - 5 < \( \frac{x}{6} \)
6 x (-4x - 5) < x
(6 x -4x) + (6 x -5) < x
-24x - 30 < x
-24x - 30 - x < 0
-24x - x < 30
-25x < 30
x < \( \frac{30}{-25} \)
x < -1\(\frac{1}{5}\)
The dimensions of this cylinder are height (h) = 6 and radius (r) = 1. What is the volume?
| 36π | |
| 18π | |
| 49π | |
| 6π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(12 x 6)
v = 6π
If the length of AB equals the length of BD, point B __________ this line segment.

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) = 9, length (l) = 5, and width (w) = 1. What is the volume?
| 144 | |
| 6 | |
| 72 | |
| 45 |
The volume of a cube is height x length x width:
v = h x l x w
v = 9 x 5 x 1
v = 45
