If the base of this triangle is 8 and the height is 6, what is the area?
| 40 | |
| 24 | |
| 24\(\frac{1}{2}\) | |
| 49\(\frac{1}{2}\) |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 8 x 6 = \( \frac{48}{2} \) = 24
Which of the following statements about a parallelogram is not true?
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 |
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).
The dimensions of this cylinder are height (h) = 7 and radius (r) = 8. What is the volume?
| 320π | |
| 448π | |
| 32π | |
| 16π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(82 x 7)
v = 448π
Order the following types of angle from least number of degrees to most number of degrees.
right, acute, obtuse |
|
right, obtuse, acute |
|
acute, right, obtuse |
|
acute, obtuse, right |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
Solve for y:
-y + 7 > -2 + 7y
| y > 1\(\frac{1}{8}\) | |
| y > -\(\frac{5}{7}\) | |
| y > 1 | |
| y > 8 |
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.
-y + 7 > -2 + 7y
-y > -2 + 7y - 7
-y - 7y > -2 - 7
-8y > -9
y > \( \frac{-9}{-8} \)
y > 1\(\frac{1}{8}\)
