A(n) __________ is to a parallelogram as a square is to a rectangle.
trapezoid |
|
triangle |
|
rhombus |
|
quadrilateral |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
Which of the following statements about a triangle is not true?
sum of interior angles = 180° |
|
area = ½bh |
|
perimeter = sum of side lengths |
|
exterior angle = sum of two adjacent interior angles |
A triangle is a three-sided polygon. It has three interior angles that add up to 180° (a + b + c = 180°). An exterior angle of a triangle is equal to the sum of the two interior angles that are opposite (d = b + c). The perimeter of a triangle is equal to the sum of the lengths of its three sides, the height of a triangle is equal to the length from the base to the opposite vertex (angle) and the area equals one-half triangle base x height: a = ½ base x height.
A coordinate grid is composed of which of the following?
y-axis |
|
origin |
|
x-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.
Solve for c:
9c + 2 = 8 - 4c
| -1 | |
| \(\frac{6}{13}\) | |
| -\(\frac{4}{5}\) | |
| \(\frac{5}{7}\) |
To solve this equation, 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.
9c + 2 = 8 - 4c
9c = 8 - 4c - 2
9c + 4c = 8 - 2
13c = 6
c = \( \frac{6}{13} \)
c = \(\frac{6}{13}\)
What is the circumference of a circle with a diameter of 11?
| 4π | |
| 30π | |
| 2π | |
| 11π |
The formula for circumference is circle diameter x π:
c = πd
c = 11π
