The dimensions of this cube are height (h) = 6, length (l) = 2, and width (w) = 1. What is the volume?
| 56 | |
| 147 | |
| 72 | |
| 12 |
The volume of a cube is height x length x width:
v = h x l x w
v = 6 x 2 x 1
v = 12
Solve for a:
8a + 2 > \( \frac{a}{-2} \)
| a > -1\(\frac{25}{31}\) | |
| a > -1\(\frac{1}{35}\) | |
| a > \(\frac{7}{10}\) | |
| a > -\(\frac{4}{17}\) |
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.
8a + 2 > \( \frac{a}{-2} \)
-2 x (8a + 2) > a
(-2 x 8a) + (-2 x 2) > a
-16a - 4 > a
-16a - 4 - a > 0
-16a - a > 4
-17a > 4
a > \( \frac{4}{-17} \)
a > -\(\frac{4}{17}\)
A(n) __________ is to a parallelogram as a square is to a rectangle.
triangle |
|
trapezoid |
|
quadrilateral |
|
rhombus |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
Which types of triangles will always have at least two sides of equal length?
equilateral and isosceles |
|
equilateral, isosceles and right |
|
equilateral and right |
|
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.
Solve for c:
4c + 4 > -3 + 2c
| c > -3\(\frac{1}{2}\) | |
| c > -\(\frac{4}{5}\) | |
| c > \(\frac{1}{3}\) | |
| c > -1 |
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.
4c + 4 > -3 + 2c
4c > -3 + 2c - 4
4c - 2c > -3 - 4
2c > -7
c > \( \frac{-7}{2} \)
c > -3\(\frac{1}{2}\)
