A(n) __________ is to a parallelogram as a square is to a rectangle.
triangle |
|
trapezoid |
|
rhombus |
|
quadrilateral |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
The dimensions of this cube are height (h) = 3, length (l) = 5, and width (w) = 6. What is the volume?
| 16 | |
| 18 | |
| 12 | |
| 90 |
The volume of a cube is height x length x width:
v = h x l x w
v = 3 x 5 x 6
v = 90
Which of the following is not a part of PEMDAS, the acronym for math order of operations?
exponents |
|
addition |
|
division |
|
pairs |
When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
If side x = 11cm, side y = 8cm, and side z = 10cm what is the perimeter of this triangle?
| 35cm | |
| 37cm | |
| 26cm | |
| 29cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 11cm + 8cm + 10cm = 29cm
For this diagram, the Pythagorean theorem states that b2 = ?
a2 - c2 |
|
c - a |
|
c2 - a2 |
|
c2 + a2 |
The Pythagorean theorem defines the relationship between the side lengths of a right triangle. The length of the hypotenuse squared (c2) is equal to the sum of the two perpendicular sides squared (a2 + b2): c2 = a2 + b2 or, solved for c, \(c = \sqrt{a + b}\)
