If AD = 23 and BD = 14, AB = ?
| 17 | |
| 15 | |
| 12 | |
| 9 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDThe dimensions of this cube are height (h) = 2, length (l) = 5, and width (w) = 5. What is the volume?
| 9 | |
| 48 | |
| 120 | |
| 50 |
The volume of a cube is height x length x width:
v = h x l x w
v = 2 x 5 x 5
v = 50
If angle a = 39° and angle b = 50° what is the length of angle c?
| 84° | |
| 91° | |
| 80° | |
| 65° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 39° - 50° = 91°
What is the circumference of a circle with a diameter of 2?
| 8π | |
| 13π | |
| 2π | |
| 26π |
The formula for circumference is circle diameter x π:
c = πd
c = 2π
If the base of this triangle is 7 and the height is 7, what is the area?
| 58\(\frac{1}{2}\) | |
| 60 | |
| 24\(\frac{1}{2}\) | |
| 45\(\frac{1}{2}\) |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 7 x 7 = \( \frac{49}{2} \) = 24\(\frac{1}{2}\)
