A trapezoid is a quadrilateral with one set of __________ sides.
equal angle |
|
parallel |
|
equal length |
|
right angle |
A trapezoid is a quadrilateral with one set of parallel sides.
On this circle, a line segment connecting point A to point D is called:
diameter |
|
chord |
|
circumference |
|
radius |
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).
What is 8a + 7a?
| 15 | |
| 1 | |
| 15a | |
| a2 |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
8a + 7a = 15a
The dimensions of this cube are height (h) = 8, length (l) = 9, and width (w) = 1. What is the volume?
| 210 | |
| 72 | |
| 14 | |
| 48 |
The volume of a cube is height x length x width:
v = h x l x w
v = 8 x 9 x 1
v = 72
If side x = 12cm, side y = 9cm, and side z = 9cm what is the perimeter of this triangle?
| 30cm | |
| 29cm | |
| 27cm | |
| 17cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 12cm + 9cm + 9cm = 30cm
