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.

.

Answer:

C) 160 minutes

Explanation:

Given:

Time spent at registration desk = 2mins

Time spent at the cashier = 10 mins

Time spent at the ID processing station = 20 mins

Number of registration desk = 1

Number of cashiers = 3

Number of ID processing stations = 4

Let's calculate the capacity of each process using the expression: number of agents / process time

Therefore,

Capacity of registration desk =

[tex] \frac{1}{2} = 0.5 students per min[/tex]

Capacity of cashiers =

[tex] \frac{3}{10} = 0.3 students per min [/tex]

Capacity of ID processing stations =

[tex] \frac{4}{20} = 0.2 students per min[/tex]

The process capacity is equal to the bottleneck process. Here, the bottleneck process is the process with the longest time per minute which is the ID processing station.

Therefore, given a rate of 0.125 student per min and Process capacity of 0.2 student per min, we'll take 0.125 as the number of students per minute since it is lower than the process capacity.

Therefore, time taken to serve one student = [tex] \frac{1}{0.125} = 8mins [/tex]

Time taken to serve 20 students would be = 20 * 8 = 160 minutes

Answer:percentage answer is 41.7% and for the fractions its 5/12

Step-by-step explanation:

for percentage to need to get the fraction to where the twelve in 7/12 is 100 so you multiply 8.3 to 12 and get 100 but you need to multiply it to the top too so you're left with 58.3/100 but that's the fraction of the goal made so what you do is subtract 58.3 from one hundred and you get 41.7 making your total 41.7%.

the way to solve the fraction is to start by subtracting the overall point to the points made and the sum would be the points missed and the point missed are 5/12 and that fraction is simplified to the max

Answer:

Step-by-step explanation:

For 20 hours a week, I earn $15 per hour, and I earn $15,600 annually. As noted on my W-4 form, I can assert my exemptions. Every year the Internal Revenue Service declares allowances for exemptions. A single person's current allowance for one exception is $3,950. I may assert another exemption for a partner of $ 3,950. At $3,950 each, I can also assert exemptions for any dependents. Suppose my contribution is 10 percent to a 401(k) retirement plan: $15,600-$1,560 = 14,040 dollars I am single, so on my W-4 form, I claimed one exemption which I submitted to my employer: 14,040-3,950 dollars = 10,090 dollars My gross revenue (minus exemptions and deductions) is therefore $ 10,090. Currently based on $10,090, I can measure the federal income tax, social security, and other withholdings My employer withholds federal tax, tax on social security, and tax on Medicare cash. For 2015, the federal income tax brackets are as follows: Tax Rate Taxable Income Levels 10% $0–$9,225 15% $9,226–$37,450 25% $37,451–$90,750 28% $90,751–$189,300 33% $189,301–$411,500 35% $411,501–$413,200 39.60% Above $413,200 The tax bracket for my income is 15 percent. However, I am not taxed 15 percent on the entire amount. I will be taxed 10 percent for the first $9,225 dollars earned. Then, I will be taxed 15 percent on the remaining amount: 10 percent of 9,225 = $922.50 15 percent of ($10,090 – $9,225) = $129.75 Total income tax = $1,522.25 Thus, my income minus federal tax ($10,090 – $1,522.25) is $9,037.75. The Social Security tax is 6.2 percent, and the Medicare tax is 1.45 percent. These taxes are calculated based on my gross income: 6.2 percent of $15,600 = $967.20 1.45 percent of $15,600 = $226.20 Thus, my net pay will be: $9,037.75 – (967.20 + 226.20) = $7,844.35.

Step-by-step explanation:

Answer:

See explanation below

Step-by-step explanation:

In this case, let's answer this by parts:

a) Concentration at time t when Co  is concentration at t = 0:

In this case, we will use the initial expression but without the 2, so:

C(t) = -kC

In this case, we want to know the concentration at time t so:

C'(t) = -kC(t)    derivating:

dC/dt = -kC

dC/C = -kdt   From here, we can do integrals so:

lnC = -kt + C₁   (1)

Now, it's time to replace t = 0 and C = C₀:

lnC₀ = -k(0) + C₁

lnC₀ = C₁   (2)

Replacing (2) in (1) we have:

lnC = -kt + lnC₀

lnC - lnC₀ = -kt

ln(C/C₀) = -kt

C/C₀ = e^(-kt)

C(t) = C₀ e^(-kt)   (3)

This is the expression for C at given time t.

2. time to eliminate 80% of the drug:

With the first data, we need to calculate the value of k, which will be constant at any given time so:

C(t) = C₀ e^(-kt)

0.5C₀ = C₀ e^(-30k)

0.5 = e^(-30k)

ln(0.5) = -30k

k = 0.02310

Now with this value we can calculate the time to eliminate 80% of the drug or simply in other words, that we just have a remaining of 0.2C₀:

0.2C₀ = C₀ e^(-0.0231t)

ln(0.2) = -0.0231t

-ln(0.2) / 0.0231 = t

t = 69.67 h

This is the time to eliminate 80% of the drug

Answer:

4.5 Kg

Step-by-step explanation:

Given that 500 gms of dough is required to make one sourdough loaf.

And we need 9 such loaves.

We can find the required weight of dough simply by adding 500 gms , 9 times.

i.e. 500 gms + 500 gms + 500 gms + 500 gms + 500 gms + 500 gms + 500 gms + 500 gms + 500 gms = 4500 gms.

Or we can simply multiply 500 gms by 9 to get 4500 gms.

We know that 1 kilogram = 1000 grams.

So, dividing 4500 grams by 1000 to convert into kilogram.

[tex]\Rightarrow \dfrac{4500} {1000}\\\Rightarrow 4.5 kg[/tex]

So, the required weight of dough for making 9 sourdough loaves is 4.5 kg.

Answer:

a) 2b = 3g

b) 3p = b

Step-by-step explanation:

Given:

Fire hydrant with a blue cap, b, provides water at a rate = 1500 gallons per min

Fire hydrant with a green cap, g, provides water at a rate = 1000 gallons per min

Fire hydrant with a purple cap, p, provides water at a rate = ½g = [tex] \frac{1}{2}*1000 = 500 [/tex]

a) The equation to relate the flow of water from the blue hydrant, b, to the flow from the green hydrant, g.

Given flow of blue hydrant, b = 500

Simplifying, we have:

b = 3*500

[tex] b = 3 * \frac{1000}{2} [/tex]

Since the flow rate of green hydrant, g, is 1000, let's replace 1000 with g above.

Therefore,

[tex] b = 3 * \frac{g}{2} [/tex]

[tex] b = \frac{3}{2}g [/tex]

Cross multuply

[tex] 2b = 3g [/tex]

The equation to relate the flow of water from the blue hydrant, b, to the flow from the green hydrant, g is 2b=3g.

b) An equation to relate the flow of water from the purple hydrant, p, to the flow from the blue hydrant, b.

Given flow rate of purple hydrant, p = 500

It could also be re-written as:

[tex] \frac{3}{3} * 500 [/tex]

[tex] p = \frac{1500}{3} [/tex]

Since the flow rate of blue hydrant, b, is 1500, let's replace 1500 with b above.

[tex] p = \frac{b}{3} [/tex]

Cross multiply

3p = b

The relation between the flow of water between different caps is required.

The relations are b = (3/2)g and p = (1/3)b

b = Rate of water flow through blue cap = 1500 gallons per minute

g = Rate of water flow through green cap = 1000 gallons per minute

p = Rate of water flow through purple cap = 1000/2 = 500 gallons per minute

We have the relation

[tex]1000\times 1.5=1500[/tex]

[tex]\Rightarrow g1.5=b[/tex]

[tex]\Rightarrow b=\dfrac{3}{2}g[/tex]

For second part

[tex]500 \times 3=1500[/tex]

[tex]\Rightarrow p3=b[/tex]

[tex]\Rightarrow p=\dfrac{1}{3}b[/tex]

Here's your answer;

The word trigonometry is derived from two Greek words trigon and metron. Trigono means triangle and metron means measurement. Therefore in literal terms trigonometry is the measurement of the angles of a triangle. The application of trigonometry is very vast.It is used in measuring eight and distance, surveys,Map making, astronomy, engineering etc.

The longest side,which is the opposite side of right angle is the hypotenuse.There are two other side's,the opposite and the adjacent.The naming of these sides depends upon which angle is involved.The opposite is the side opposite the angle involved and it is called the perpendicular.

The adjacent is the side next to the angle involved(but not the hypotenuse) and it is called base.

  3) 174°15'18"

  4) 34.859722...(repeating)°

  5) 434°, -286°

Step-by-step explanation:

There are 60 minutes in a degree, and 60 seconds in a minute.

3) To find minutes, multiply fractional degrees by 60:

  .255° = 0.255°×(60'/1°) = 15.3'

To find seconds, multiply fractional minutes by 60:

  0.3' = 0.3'×(60"/1') = 18"

Then the whole angle is ...

  174.255° = 174° 15' 18"

__

4) The conversion works the other way, too.

  34° 51' 35" = 34° +51(1/60)° +35(1/3600)° = (34 619/720)°

  = 34.8597222...° (a repeating decimal)

__

5) Add or subtract multiples of 360° to get co-terminal angles.

  74° +360° = 434°

  74° -360° = -286°
