The dimensions of this cube are height (h) = 6, length (l) = 7, and width (w) = 6. What is the volume?
| 252 | |
| 4 | |
| 42 | |
| 12 |
The volume of a cube is height x length x width:
v = h x l x w
v = 6 x 7 x 6
v = 252
Which of the following statements about a parallelogram is not true?
a parallelogram is a quadrilateral |
|
the perimeter of a parallelogram is the sum of the lengths of all sides |
|
the area of a parallelogram is base x height |
|
opposite sides and adjacent angles are equal |
A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).
Solve 5b - 7b = -6b - 2z + 4 for b in terms of z.
| -1\(\frac{1}{5}\)z + 1 | |
| \(\frac{5}{11}\)z + \(\frac{4}{11}\) | |
| -\(\frac{1}{10}\)z - \(\frac{3}{5}\) | |
| 10z - 3 |
To solve this equation, isolate the variable for which you are solving (b) on one side of the equation and put everything else on the other side.
5b - 7z = -6b - 2z + 4
5b = -6b - 2z + 4 + 7z
5b + 6b = -2z + 4 + 7z
11b = 5z + 4
b = \( \frac{5z + 4}{11} \)
b = \( \frac{5z}{11} \) + \( \frac{4}{11} \)
b = \(\frac{5}{11}\)z + \(\frac{4}{11}\)
If angle a = 52° and angle b = 61° what is the length of angle c?
| 74° | |
| 104° | |
| 67° | |
| 106° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 52° - 61° = 67°
