The dimensions of this cube are height (h) = 1, length (l) = 3, and width (w) = 5. What is the volume?
| 120 | |
| 50 | |
| 320 | |
| 15 |
The volume of a cube is height x length x width:
v = h x l x w
v = 1 x 3 x 5
v = 15
A coordinate grid is composed of which of the following?
x-axis |
|
y-axis |
|
all of these |
|
origin |
The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.
If angle a = 62° and angle b = 59° what is the length of angle d?
| 118° | |
| 134° | |
| 147° | |
| 137° |
An exterior angle of a triangle is equal to the sum of the two interior angles that are opposite:
d° = b° + c°
To find angle c, remember that the sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 62° - 59° = 59°
So, d° = 59° + 59° = 118°
A shortcut to get this answer is to remember that angles around a line add up to 180°:
a° + d° = 180°
d° = 180° - a°
d° = 180° - 62° = 118°
Which of the following expressions contains exactly two terms?
monomial |
|
polynomial |
|
quadratic |
|
binomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
The endpoints of this line segment are at (-2, 0) and (2, -4). What is the slope of this line?
| 1\(\frac{1}{2}\) | |
| 3 | |
| 2\(\frac{1}{2}\) | |
| -1 |
The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, 0) and (2, -4) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(-4.0) - (0.0)}{(2) - (-2)} \) = \( \frac{-4}{4} \)
