The formula for volume of a cube in terms of height (h), length (l), and width (w) is which of the following?
h x l x w |
|
h2 x l2 x w2 |
|
lw x wh + lh |
|
2lw x 2wh + 2lh |
A cube is a rectangular solid box with a height (h), length (l), and width (w). The volume is h x l x w and the surface area is 2lw x 2wh + 2lh.
If angle a = 52° and angle b = 68° what is the length of angle c?
| 109° | |
| 114° | |
| 60° | |
| 121° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 52° - 68° = 60°
Solve for c:
-6c + 4 = -1 - 8c
| 4 | |
| -2\(\frac{1}{2}\) | |
| \(\frac{1}{2}\) | |
| \(\frac{4}{5}\) |
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 equal sign and the answer on the other.
-6c + 4 = -1 - 8c
-6c = -1 - 8c - 4
-6c + 8c = -1 - 4
2c = -5
c = \( \frac{-5}{2} \)
c = -2\(\frac{1}{2}\)
Which of the following expressions contains exactly two terms?
polynomial |
|
monomial |
|
binomial |
|
quadratic |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
This diagram represents two parallel lines with a transversal. If w° = 32, what is the value of x°?
| 19 | |
| 18 | |
| 148 | |
| 34 |
For parallel lines with a transversal, the following relationships apply:
Applying these relationships starting with w° = 32, the value of x° is 148.
