If each light fixture on a job requires 4 lamps and each room requires 16 fixtures, how many lamps will be required for 6 rooms?

1 answer:

7 0

Answer:

384 lamps

Step-by-step explanation:

This is simply a multiplication problem. From the question, we know that each fixture needs 4 lamps with a single room needing 16 fixtures.

The number of lamps required by each room is thus 16 * 4 = 64 lamps

Now, the total number of lamps required by 6 rooms is thus 64 * 6 = 384 lamps

Interval simply represent the set of numbers containing all numbers between any two numbers.

The representations of $(-\infty, -6]$ are $\{x| x \in R, x \le -6 \}$ and $x \le -6$

From the question, we have:

$(-\infty, -6]$

The above representation is in interval notation.

The interpretation is that;

The highest number in the interval is -6

The equivalent using set notation is:

$\{x| x \in R, x \le -6 \}$

The equivalent using inequalities is:

$x \le -6$
