Answer:

Option 3 - 45 tens

Step-by-step explanation:

Given : Expression 45 ones times 10.

To find : What is the expression?

Solution :

We know that,

"one" means " 1

We have 45 ones means multiply 45 by 1.

$45\text{ ones}=45\times 1=45$

Now, 45 ones times 10 means

$45\times 10=450$

450 means 45 tens as tens is 10.

So, The correct choice is 45 tens.

Therefore, Option 3 is correct.

Evaluate A ^ 2 for A = - 3 . -9 -6 6 9

kari74 [83]

Answer:

Step-by-step explanation:

We want to evaluate

$A^2$

for A=-3.

This means, we need to substitute A=-2, into the given equation and simplify.

We substitute to get:

$A^2 = {( - 3)}^{2}$

In this case the base is -3, so it multiplies itself twice.

$A^2 = {( - 3)} \times - 3$

This gives us:

$A^2 = 9$

Students are going through a three-step process to obtain their ID cards. Each student will spend 2 minutes at the registration

kondaur [170]

Answer:

C. 160 minutes

Step-by-step explanation:

The calculation to be made will be to process 20 students

We have, according to the exercise, the following data:

For process 1: Registration table, Number of servers = 1, Time spent = 2 minutes

For process 2: cashier, number of servers = 3, time spent = 10 minutes

For process 3: ID processing station, number of servers = 4, time spent = 20 minutes

Demand rate = 0.125

To solve it, we will look for the capacity that the server has of the previously mentioned processes, calculating the following:

Capacity = Number of students served per minute

We can say that at the registration table we observe:

Time needed to serve 1 student = 2 minutes

Capacity = 0.5 students per minute

With the cashier we analyze the following:

Time needed to serve 1 student = 10 minutes

Number of servers = 3

Capacity = 0.3 students per minute

ID processing station

Time needed to serve 1 student = 20 minutes

Number of servers = 4

Capacity = 0.2 students per minute

When comparing the processes, it is definitely found that the bottleneck is the ID processing station, where it takes more time to serve a student, which leads us to infer that the capacity of the process is comparable to the capacity of the process bottleneck

Process capacity = 0.2 students per minute

Given, demand rate = 0.125 students per minute

We observe that the demand rate is less than the capacity of the process, therefore we can infer that the number of students served during each minute is the same as the demand rate.

In this way we find that:

Number of students served per minute = 0.125

Time needed to serve 1 student = 1 / 0.125 = 8 minutes

Time needed to serve 20 students = 8 x 20 = 160 minutes.

We conclude that the answer is that it will take 160 minutes to serve 20 students.
