A(n) __________ is to a parallelogram as a square is to a rectangle.
trapezoid |
|
triangle |
|
quadrilateral |
|
rhombus |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
If side x = 5cm, side y = 12cm, and side z = 6cm what is the perimeter of this triangle?
| 27cm | |
| 22cm | |
| 23cm | |
| 31cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 5cm + 12cm + 6cm = 23cm
Simplify 6a x 2b.
| 12\( \frac{b}{a} \) | |
| 12\( \frac{a}{b} \) | |
| 12ab | |
| 12a2b2 |
To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
6a x 2b = (6 x 2) (a x b) = 12ab
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 |
|
2lw x 2wh + 2lh |
|
lw x wh + lh |
|
h2 x l2 x w2 |
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.
On this circle, a line segment connecting point A to point D is called:
radius |
|
chord |
|
circumference |
|
diameter |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
