If the base of this triangle is 8 and the height is 7, what is the area?
| 97\(\frac{1}{2}\) | |
| 35 | |
| 33 | |
| 28 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 8 x 7 = \( \frac{56}{2} \) = 28
If angle a = 65° and angle b = 66° what is the length of angle c?
| 49° | |
| 101° | |
| 86° | |
| 88° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 65° - 66° = 49°
The endpoints of this line segment are at (-2, -9) and (2, 3). What is the slope of this line?
| -2\(\frac{1}{2}\) | |
| -2 | |
| -1\(\frac{1}{2}\) | |
| 3 |
The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, -9) and (2, 3) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(3.0) - (-9.0)}{(2) - (-2)} \) = \( \frac{12}{4} \)If a = 9, b = 8, c = 5, and d = 1, what is the perimeter of this quadrilateral?
| 22 | |
| 23 | |
| 17 | |
| 16 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 9 + 8 + 5 + 1
p = 23
The dimensions of this cube are height (h) = 1, length (l) = 7, and width (w) = 5. What is the volume?
| 96 | |
| 35 | |
| 80 | |
| 64 |
The volume of a cube is height x length x width:
v = h x l x w
v = 1 x 7 x 5
v = 35
