The handwritten signs indicate that a piece of pie costs $.10\cancel{c}$ and a cup of coffee costs $.5\cancel{c}$. Assuming these are the actual prices, how many cups of coffee can you get for $\$ 1.00$?

To determine the torque at a given value of rpm, the formula below applies:

$$\text { Torque }=\frac{5252 \times \text { horsepower }}{\text { rpm }}.$$

If the horsepower of a certain vehicle is $400$ at $4500\text{ rpm}$, what is the approximate torque?

Calculate $2.45(1.2+3.4-5.6)$ using either a calculator or paper-and-pencil methods, as directed by your instructor.

Use a calculator to find a rational decimal approximation for $\sqrt{15.1}$. Give as many places as your calculator shows.

Identify each number as rational or irrational. (a) $\sqrt{10}$ (b) $\sqrt{16}$ ($\text{}$c) $0.01$ (d) $0 . \overline{01}$ (e) $0.0101101110 \ldots$ (f) $\pi$

The handwritten signs indicate that a piece of pie costs $.10\cancel{c}$ and a cup of coffee costs $.5\cancel{c}$. Assuming these are the actual prices, how much will $20$ pieces of pie and $10$ cups of coffee cost?

Perform the indicated operations, using the order of operations as necessary.

$$12-(-3)-(-5)$$

Convert each decimal into a quotient of integers, reduced to lowest terms. (a) $0.72$ (b) $0 . \overline{58}$

The approximate speed of an automobile in miles per hour $(\text{MPH})$ can be found in terms of the engine's revolutions per minute $(\text{rpm})$, the tire diameter in inches, and the overall gear ratio by the formula

$$\text { MPH }=\frac{\text { rpm } \times \text { tire diameter }}{\text { gear ratio } \times 336}.$$

If a certain automobile has an rpm of $5600$, a tire diameter of $26$ inches, and a gear ratio of $3.12$, what is its approximate speed $(\text{MPH})$?

Use a calculator to find a rational decimal approximation for $\sqrt{44}$. Give as many places as your calculator shows.

The handwritten signs indicate that a piece of pie costs $.10\cancel{c}$ and a cup of coffee costs $.5\cancel{c}$. Assuming these are the actual prices, how much will $10$ pieces of pie and $10$ cups of coffee cost?

Use a calculator to find a rational decimal approximation for $\sqrt{39}$. Give as many places as your calculator shows.

Convert each rational number into a repeating or terminating decimal. Use a calculator if your instructor so allows. (a) $\frac{9}{20}$ (b) $\frac{5}{12}$

Convert each decimal into a quotient of integers, written in lowest terms.

$$0.1\overline{2}$$
