An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
The dimensions of this cube are height (h) = 3, length (l) = 2, and width (w) = 5. What is the volume?
| 126 | |
| 42 | |
| 30 | |
| 224 |
The volume of a cube is height x length x width:
v = h x l x w
v = 3 x 2 x 5
v = 30
Solve for z:
-9z - 2 > -9 + 6z
| z > 4 | |
| z > -2\(\frac{1}{2}\) | |
| z > -1 | |
| z > \(\frac{7}{15}\) |
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.
-9z - 2 > -9 + 6z
-9z > -9 + 6z + 2
-9z - 6z > -9 + 2
-15z > -7
z > \( \frac{-7}{-15} \)
z > \(\frac{7}{15}\)
Which types of triangles will always have at least two sides of equal length?
isosceles and right |
|
equilateral and isosceles |
|
equilateral and right |

equilateral, 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.
The dimensions of this cylinder are height (h) = 5 and radius (r) = 8. What is the volume?
| 64π | |
| 320π | |
| 36π | |
| 3π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(82 x 5)
v = 320π
