How many different 7-digit telephone numbers are possible if the first digit cannot be 0, but the last two digits must be 0?
solniwko [45]
The first digit can only range from 1-9, resulting in 9 possible options. The next four digits can range from 0-9, resulting in 10 options for each. Since the last two digits remain the same, they do not affect the sample size. Using the fundamental counting principle, we can find the amount of telephone numbers possible in the following equation.
9 \times 10 \times 10 \times 10 \times 10 \times 1 \times 1 \\ 90000

Jacob wants to use an elevator to carry identical packages having the same weight. Each package weighs 3 pounds and Jacob weighs
zzz [600]

Answer:

The required inequality that shows the maximum number of packages is n\leq 67.

Step-by-step explanation:

Consider the provided information.

Each package weighs 3 pounds and Jacob weighs 99 pounds.

let <em>n</em> is the maximum number of package that Jacob can carry with himself in the elevator.

Thus, the total weight of Jacob while having <em>n</em> packages on the elevator is:

3n+99

The elevator can carry a maximum of 300 pounds at a time, therefore.

3n+99\leq 300

Now, subtract 99 from both sides and divide the obtained inequality with 3.

3n+99-99\leq 300-99

3n\leq 201

\frac{3n}{3}\leq \frac{201}{3}

n\leq 67

Thus, the Jacob can carry maximum 67 packages.

Hence, the required inequality that shows the maximum number of packages is n\leq 67.
