Convert 225 $\mathrm{kPa}$ pressure to an equivalent pressure in atmospheres.

Does factoring, completing the square, or using the quadratic formula seem to you the easiest method for solving the given equation?

$4 x^2-x-7=0$

Which of the following invertebrates have segmented bodies?

A flatworms

B roundworms

C cnidarians

D annelids

When solving an equation with variables in the denominators, it's important to know the values that make the denominators equal 0, so we can eliminate any erroneous answers that might emerge. Find all values where at least one of the denominators is 0. Write your responses using the $\neq$ symbol. Avoid solving.

$$\dfrac{3}{x+2}-\dfrac{5}{x}=1$$

The table below shows Giorgio's scores at a state golf tournament. What is Giorgio's average score for the five rounds?

Mark the following true or false.

The product of two units in $\mathbb{Z}_n$ is always a unit.

Under which of the following sets of conditions would a real gas behave most like an ideal gas?

(a) low pressure, low temperature

(b) high pressure, high temperature

(c) low pressure, high temperature

(d) high pressure, low temperature

Write a short, precise phrase that defines each vocabulary term below. For example, a short phrase to describe exoskeleton could be "hard, outer covering." segmentation

In addition to the Seljuks, who else used the title sultan?

State whether each of the following is true or false. Justify your answer.

(a). Any two non-parallel lines in $R^2$ must always intersect at a point.

(b). Any two non-parallel planes in $R^3$ must always intersect on a line.

($c$). The line with equation $x=y=z$ will always intersect the plane with equation $x-2 y+2 z=k$, regardless of the value of $k$.

(d). The lines $\frac{x}{2}=y-1=\frac{z+1}{2}$ and $\frac{x-1}{-4}=\frac{y-1}{-2}=\frac{z+1}{-2}$ are parallel.

Use radian measure to measure and mark every $\frac{\pi}{6}$ around the circle.

Mark the following true or false.

In any UFD, if p | a for an irreducible p, then p itself appears in every factorization of a.

Examine the pairs of angles b and d, g and j, and r and s. If you add the measures of each pair, what do you observe? Write a conjecture about two angles on the same side of a transversal which are between two parallel lines. Note: these are called interior angles with respect to the two parallel lines.

For this exercise, add using expanded notation.
