Final answer:
To evaluate qr when q = 4 and r = 7.3, we simply multiply the two values together: qr = 4 * 7.3. The product is 29.2.
Step-by-step explanation:
The expression qr represents the product of q and r. To evaluate qr when q = 4 and r = 7.3, we simply multiply the two values together: qr = 4 * 7.3.
Using a calculator, we find that 4 * 7.3 = 29.2. Therefore, qr = 29.2.
