Which types of triangles will always have at least two sides of equal length?
equilateral, isosceles and right |
|
equilateral and right |
|
equilateral and isosceles |
|
isosceles and right |
An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
bisects |
|
midpoints |
|
intersects |
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 b:
2b - 2 < \( \frac{b}{-3} \)
| b < -2\(\frac{2}{27}\) | |
| b < -6\(\frac{2}{3}\) | |
| b < 2\(\frac{5}{8}\) | |
| b < \(\frac{6}{7}\) |
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.
2b - 2 < \( \frac{b}{-3} \)
-3 x (2b - 2) < b
(-3 x 2b) + (-3 x -2) < b
-6b + 6 < b
-6b + 6 - b < 0
-6b - b < -6
-7b < -6
b < \( \frac{-6}{-7} \)
b < \(\frac{6}{7}\)
The dimensions of this cube are height (h) = 8, length (l) = 9, and width (w) = 3. What is the volume?
| 192 | |
| 96 | |
| 216 | |
| 168 |
The volume of a cube is height x length x width:
v = h x l x w
v = 8 x 9 x 3
v = 216
