You go to the doctor and he gives you 16 milligrams of radioactive dye. After 16 minutes, 7.25 milligrams of dye remain in your system. To leave the doctor's office, you must pass through a radiation detector without sounding the alarm. If the detector will sound the alarm if more than 2 milligrams of the dye are in your system, how long will your visit to the doctor take, assuming you were given the dye as soon as you arrived? Give your answer to the nearest minute. You will spend ????? minutes at the doctor's office.

The Corona Virus, that started to spread in many countries in early 2020, is more contagious than the common flu. Many people are infected, and many of the infected died. The number of deaths resulting from the coronavirus can be calculated as a result of the infection rate and the mortality rate. The infection rate is the number of persons in a population of 1,000,000 people who are likely to get infected. For this exercise, we assume the infection rate ranges from 10 to 25 people per million (PPM). Likewise, we assume the mortality rate (the death rate) ranges from 1000 to 2500 people per million infected (PPMI). These rates are doubled for a susceptible population (that is people who are above 60 or have other health issues). Given these data, answer the following questions. For each question, always start with the original values given here. 1) In a country with a population of 18 million, 30% of the population is above 60 years of age and the other 5% of the total population are…
A classmate decides to buy a used Honda Civic from a local dealership. At purchase, the car had 34000 miles on the odometer. Your sister believes she'll be doing 18500 miles per year in the car. If the average lifespan of a Honda Civic is 300,000 miles, how long does she have until she needs a new car? Your answer must have a justified algebraic model to receive full credit.
We are constructing a box from a piece of paper. The paper is a piece of “ledger-sized paper” which measures 11”x17”. We will remove a square of size “x” inches from each corner and turn up the edges.A piece of ledger paper is the same size as taping the long sides of two pieces of standard 8.5x11 paper together. Once we remove the squares of size “x” inches from each corner and turn up the edges, we create a box: Label the dimensions of the newly created box using the variable “x”. h=h= w=w= l=l= What is the equation that represents the Volume of the box as a function of the cutsize of the box? V(x)=Vx= What is the restricted domain of this problem? (That is, what x values "make sense"?) ≤x≤≤x≤ What is the restricted range of this problem? (That is, what V values "make sense"?) ≤V(x)≤≤Vx≤ (round to 2 decimal places) To maximize the volume of the newly created box, how much should be cut from each corner? x=x= inches What is…
At inventory time, 435 pounds of magnet wire for winding motors is available. In ten successive days, 15 pounds, 6 pounds, 24 pounds, 12 pounds, 3 pounds, 8 pounds, 17 pounds, 32 pounds, 16 pounds, and 13 pounds of wire are taken out of stock. How many pounds are left?
You have 40 sheep, and can get a 2/3 of a bushel of wool from each. You want to buy 1100 bricks from the kiln to enclose a sheepfold to protect your flock. The kiln operator charges a shekel of copper for each 5 bricks. The trader from Anatolia wants as much wool as possible, and will give you 7 shekels of copper for each bushel. So obviously you want to sell your wool to the trader, and then buy the bricks. Write this out as an algebraic problem. Give names for all of the quantities, such as sheep, shekels, etc. But can you buy the 1100 bricks you need? How many bushels of wool extra would you have beyond what you need for the bricks, or how many are you missing? How many sheep does that represent?
You go to the doctor and he gives you 16 milligrams of radioactive dye. After 24 minutes, 5.75 milligrams of dye remain in your system. To leave the doctor's office, you must pass through a radiation detector without sounding the alarm. If the detector will sound the alarm if more than 2 milligrams of the dye are in your system, how long will your visit to the doctor take, assuming you were given the dye as soon as you arrived? Give your answer to the nearest minute. You will spend______ minutes at the doctor's office.
