A(n) __________ is to a parallelogram as a square is to a rectangle.
rhombus |
|
triangle |
|
trapezoid |
|
quadrilateral |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
Solve for b:
7b - 4 < -3 + 2b
| b < \(\frac{1}{5}\) | |
| b < 1\(\frac{1}{3}\) | |
| b < -1 | |
| b < -2\(\frac{1}{4}\) |
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 < sign and the answer on the other.
7b - 4 < -3 + 2b
7b < -3 + 2b + 4
7b - 2b < -3 + 4
5b < 1
b < \( \frac{1}{5} \)
b < \(\frac{1}{5}\)
If a = c = 1, b = d = 6, what is the area of this rectangle?
| 8 | |
| 6 | |
| 14 | |
| 40 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 1 x 6
a = 6
For this diagram, the Pythagorean theorem states that b2 = ?
c2 + a2 |
|
c2 - a2 |
|
c - a |
|
a2 - c2 |
The Pythagorean theorem defines the relationship between the side lengths of a right triangle. The length of the hypotenuse squared (c2) is equal to the sum of the two perpendicular sides squared (a2 + b2): c2 = a2 + b2 or, solved for c, \(c = \sqrt{a + b}\)
Order the following types of angle from least number of degrees to most number of degrees.
acute, obtuse, right |
|
acute, right, obtuse |
|
right, obtuse, acute |
|
right, acute, obtuse |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
