Which of the following is not a part of PEMDAS, the acronym for math order of operations?
pairs |
|
addition |
|
exponents |
|
division |
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.)
The dimensions of this cylinder are height (h) = 7 and radius (r) = 7. What is the volume?
| 5π | |
| 343π | |
| 63π | |
| 18π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(72 x 7)
v = 343π
If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
bisects |
|
midpoints |
|
intersects |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
What is 9a5 - 8a5?
| 1 | |
| 17 | |
| 1a5 | |
| a10 |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
9a5 - 8a5 = 1a5
On this circle, line segment AB is the:
chord |
|
circumference |
|
radius |
|
diameter |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
