A(n) __________ is to a parallelogram as a square is to a rectangle.
trapezoid |
|
rhombus |
|
quadrilateral |
|
triangle |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
Solve for y:
8y - 6 > \( \frac{y}{-7} \)
| y > \(\frac{14}{19}\) | |
| y > 1\(\frac{1}{41}\) | |
| y > \(\frac{6}{13}\) | |
| y > 4\(\frac{1}{6}\) |
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.
8y - 6 > \( \frac{y}{-7} \)
-7 x (8y - 6) > y
(-7 x 8y) + (-7 x -6) > y
-56y + 42 > y
-56y + 42 - y > 0
-56y - y > -42
-57y > -42
y > \( \frac{-42}{-57} \)
y > \(\frac{14}{19}\)
Which types of triangles will always have at least two sides of equal length?
equilateral and right |
|
equilateral, isosceles and right |
|
isosceles and right |
|
equilateral and isosceles |
An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
The dimensions of this cylinder are height (h) = 5 and radius (r) = 7. What is the volume?
| 245π | |
| 648π | |
| 162π | |
| 567π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(72 x 5)
v = 245π
Which of the following is not true about both rectangles and squares?
the lengths of all sides are equal |
|
the perimeter is the sum of the lengths of all four sides |
|
the area is length x width |
|
all interior angles are right angles |
A rectangle is a parallelogram containing four right angles. Opposite sides (a = c, b = d) are equal and the perimeter is the sum of the lengths of all sides (a + b + c + d) or, comonly, 2 x length x width. The area of a rectangle is length x width. A square is a rectangle with four equal length sides. The perimeter of a square is 4 x length of one side (4s) and the area is the length of one side squared (s2).
