A trapezoid is a quadrilateral with one set of __________ sides.
right angle |
|
parallel |
|
equal length |
|
equal angle |
A trapezoid is a quadrilateral with one set of parallel sides.
The dimensions of this cylinder are height (h) = 4 and radius (r) = 5. What is the volume?
| 36π | |
| 100π | |
| 196π | |
| 24π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(52 x 4)
v = 100π
Solve for b:
-4b - 3 > \( \frac{b}{-2} \)
| b > \(\frac{15}{16}\) | |
| b > \(\frac{14}{57}\) | |
| b > -\(\frac{24}{41}\) | |
| b > -\(\frac{6}{7}\) |
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.
-4b - 3 > \( \frac{b}{-2} \)
-2 x (-4b - 3) > b
(-2 x -4b) + (-2 x -3) > b
8b + 6 > b
8b + 6 - b > 0
8b - b > -6
7b > -6
b > \( \frac{-6}{7} \)
b > -\(\frac{6}{7}\)
Which of the following expressions contains exactly two terms?
monomial |
|
binomial |
|
polynomial |
|
quadratic |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
The formula for the area of a circle is which of the following?
c = π r |
|
c = π d |
|
c = π d2 |
|
c = π r2 |
The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)2 : a = π r2.
