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
2. A hotel has 18 floors. The hotel owner believes the number 13 is
unlucky. The first 12 floors are numbered from 1 to 12. Floor 13 is
numbered 14, and the remaining floors are numbered from 15 to 19.
The hotel manager starts on the top floor of the apartment building. He
rides the elevator two floors down. The doors open and a hotel guest
gets in. They ride the elevator three floors down. The hotel guest gets
off the elevator. The hotel manager rides the elevator the remaining
floors down to the first floor. On what floor did the hotel guest get off the elevator? Explain.
What is the answer for B?
Answer:
See below
Step-by-step explanation:
The manager rides down 2 floors from 19 floor which means he stops at floor 17, the floor he rides down as negative integer = -2. Then, he rides down 3 floors and it means he stops at floor 14. This means the number of floors he rides down from there = -3
then he rides to the first floor as there is no number 13 floor it means he rides down 12 floor = -12
the addition expression using negative integers to show the number of total floors the hotel manager rode down the elevator = -2 + (-3) + (-12) = -17
A fire hydrant with a blue cap provides water at a rate of 1,500 gallons per minute. A fire hydrant with a green cap provides water at a rate of 1,000 gallons per minute. A fire hydrant with a purple cap provides water at half the rate of a fire hydrant with a green cap.
Part A Write an equation to relate the flow of water from the blue hydrant, b, to the flow from the green hydrant, g.
Part B Write an equation to relate the flow of water from the purple hydrant, p, to the flow from the blue hydrant, b.
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
Rateb = 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]

Students are going through a three-step process to obtain their ID cards. Each student will spend 2 minutes at the registration desk before going to one of three cashiers to pay a fee for the ID card. After that, he/she will visit one of four ID processing stations to have his/her picture taken and ID card printed. Visits to the cashier and ID processing station take 10 and 20 minutes respectively. If the demand rate is 0.125 student per minute, how long does it take to process 20 students assuming the system is full?
A. 100 minutes
B. 152 minutes
C. 160 minutes
D. 184 minutes
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

Let C(t) be the concentration of a drug in the bloodstream. As the body eliminates the drug, C(t) decreases at a rate that is proportional to the amount of the drug that is present at the time. Thus C 0 (t) = −2kC(t), where 2k is a positive number. Here is it is half of the elimination constant of the drug. (a) If Co is the concentration at time t = 0, find the concentration at time . (b) If the body eliminates half the drug in 30 hours, how long does it take to eliminate 80% of the drug?
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

What is Trigonometry
hey!!!
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.

Answer:
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°

number of hours over 20 hours you work in ane week. Your regular pay is $5 per hour for the
first 20 hours you work in one week.
Write a piecewise function to represent the amount of your weekly paycheck p(h)
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.

You need to make 9 sourdough loaves, one sourdough loaf requires 500 grams of dough How many kilograms of dough do you need
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.
