The dimensions of this cube are height (h) = 1, length (l) = 1, and width (w) = 9. What is the volume?
| 9 | |
| 48 | |
| 378 | |
| 32 |
The volume of a cube is height x length x width:
v = h x l x w
v = 1 x 1 x 9
v = 9
A coordinate grid is composed of which of the following?
x-axis |
|
origin |
|
y-axis |
|
all of these |
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 a = c = 3, b = d = 7, and the blue angle = 52°, what is the area of this parallelogram?
| 63 | |
| 56 | |
| 30 | |
| 21 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 3 x 7
a = 21
A(n) __________ is two expressions separated by an equal sign.
expression |
|
problem |
|
formula |
|
equation |
An equation is two expressions separated by an equal sign. The key to solving equations is to 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.
When two lines intersect, adjacent angles are __________ (they add up to 180°) and angles across from either other are __________ (they're equal).
obtuse, acute |
|
vertical, supplementary |
|
supplementary, vertical |
|
acute, obtuse |
Angles around a line add up to 180°. Angles around a point add up to 360°. When two lines intersect, adjacent angles are supplementary (they add up to 180°) and angles across from either other are vertical (they're equal).
