The dimensions of this cube are height (h) = 5, length (l) = 1, and width (w) = 1. What is the volume?
| 216 | |
| 16 | |
| 54 | |
| 5 |
The volume of a cube is height x length x width:
v = h x l x w
v = 5 x 1 x 1
v = 5
A(n) __________ is to a parallelogram as a square is to a rectangle.
rhombus |
|
triangle |
|
quadrilateral |
|
trapezoid |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
A(n) __________ is two expressions separated by an equal sign.
expression |
|
equation |
|
problem |
|
formula |
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.
If angle a = 21° and angle b = 70° what is the length of angle c?
| 89° | |
| 119° | |
| 94° | |
| 59° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 21° - 70° = 89°
If side x = 8cm, side y = 12cm, and side z = 15cm what is the perimeter of this triangle?
| 30cm | |
| 27cm | |
| 35cm | |
| 32cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 8cm + 12cm + 15cm = 35cm
