If a = c = 2, b = d = 1, what is the area of this rectangle?
| 2 | |
| 42 | |
| 12 | |
| 25 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 2 x 1
a = 2
On this circle, line segment CD is the:
chord |
|
diameter |
|
radius |
|
circumference |
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).
Solve for x:
2x - 5 > \( \frac{x}{-9} \)
| x > \(\frac{18}{37}\) | |
| x > 2\(\frac{7}{19}\) | |
| x > -\(\frac{10}{11}\) | |
| x > \(\frac{8}{15}\) |
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.
2x - 5 > \( \frac{x}{-9} \)
-9 x (2x - 5) > x
(-9 x 2x) + (-9 x -5) > x
-18x + 45 > x
-18x + 45 - x > 0
-18x - x > -45
-19x > -45
x > \( \frac{-45}{-19} \)
x > 2\(\frac{7}{19}\)
Order the following types of angle from least number of degrees to most number of degrees.

An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
If a = c = 3, b = d = 1, and the blue angle = 67°, what is the area of this parallelogram?

The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 3 x 1
a = 3
