Which of the following is not a part of PEMDAS, the acronym for math order of operations?
division |
|
exponents |
|
pairs |
|
addition |
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 angle a = 29° and angle b = 55° what is the length of angle c?
| 88° | |
| 96° | |
| 64° | |
| 75° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 29° - 55° = 96°
A cylinder with a radius (r) and a height (h) has a surface area of:
4π r2 |
|
π r2h2 |
|
2(π r2) + 2π rh |
|
π r2h |
A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r2h and the surface area is 2(π r2) + 2π rh.
Breaking apart a quadratic expression into a pair of binomials is called:
factoring |
|
normalizing |
|
deconstructing |
|
squaring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
If a = c = 2, b = d = 5, and the blue angle = 55°, what is the area of this parallelogram?
| 6 | |
| 42 | |
| 10 | |
| 36 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 2 x 5
a = 10
