Deandre is driving to Denver. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes). Deandre has miles to his destination after minutes of driving, and he has miles to his destination after minutes of driving. How many miles will he have to his destination after minutes of driving
Answer and explanation:
If distance to his destination(in miles) is a function of his minutes of driving(time) then the formula can suffice:
Distance = Speed × Time
if distance is 5 miles to his destination
Speed is 1 mile/hr
Time taken is 4 hrs or 240 minutes
Then Deandre would have 1 mile left to reach his destination after 240 minutes

1. 7-5 (5 goes in once)
2. you can't do 2-5 so drop down the 0. (20)
3. 5 goes into 20 4 times. add the 4 to the top
4. put the zero in since it doesn't go with anything (it should look like 1400)
5. drop the 3 down but since 5 can't go in add a zero (and a decimal to your answer on top) - 1400.
6. 5 goes into 30, 8 times.
7. final answer: 1400.8

In Part C, you determined that the proper ratio of packages of buns, packages of patties, and jars of pickles is 3:2:4. If you want to feed at least 420 people, but also maintain the proper ratio, what minimum number of packages of buns, packages of patties, and jars of pickles do you need, respectively
Answer:
packages of buns = 1,260
packages of patties = 840
Jars of pickles = 1,680
Step-by-step explanation:
packages of buns = 3
packages of patties = 2
Jars of pickles = 4
Number of people = 420
Each person of the 420 people gets packages of buns, packages of patties, and jars of pickles in the ratio 3:2:4
packages of buns needed for 420 people = 3 × 420
= 1,260
packages of patties needed for 420 people = 2 × 420
= 840
Jars of pickles needed for 420 people = 4 × 420
= 1,680
packages of buns = 1,260
packages of patties = 840
Jars of pickles = 1,680
To feed at least 420 people minimum number of packages of buns, packages of patties, and jars of pickles needed is 1,260, 840, 1,680 respectively.

Maybell just purchased $2075 worth of jewelry. If she marks up her cost by 30% and sells all of the jewelry, what will be the total retail cost of all the jewelry?
Answer:
times 2075 by .30 and that's your answer
The total retail cost of all the jewelry is $2697.5
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Maybell just purchased $2075 worth of jewelry.
Now, marks up her cost by 30% then
= 2075 x 30/100
= 622.5
Thus, the total retail cost of all the jewelry
= 2075+ 622.5
= $2697.5

A college student is taking two courses. The probability she passes the first course is 0.67. The probability she passes the second course is 0.7. The probability she passes at least one of the courses is 0.79. Give your answer to four decimal places. a. What is the probability she passes both courses
Answer:
0.58 = 58% probability she passes both courses
Step-by-step explanation:
We can solve this question treating the probabilities as a Venn set.
I am going to say that:
Event A: She passes the first course.
Event B: She passes the second course.
The probability she passes the first course is 0.67.
This means that [tex]P(A) = 0.67[/tex]
The probability she passes the second course is 0.7.
This means that [tex]P(B) = 0.7[/tex]
The probability she passes at least one of the courses is 0.79.
This means that [tex]P(A \cup B) = 0.79[/tex]
a. What is the probability she passes both courses
This is [tex]P(A \cap B)[/tex].
We use the following relation:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
So
[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B) = 0.67 + 0.7 - 0.79 = 0.58[/tex]
0.58 = 58% probability she passes both courses

Consider the NASCAR race, the Indianapolis 500. Its name refers to the total race distance of 500 miles. There are 44 cars are racing (all of them also finish), and they all have an average mileage of 6.78 miles per gallon. If the fuel cost is $1.63 per gallon, what is the total fuel cost, in dollars, for all cars finishing the entire race?
Answer: $5289.35
Step-by-step explanation:
Since the cars have an average mileage of 6.78 miles per gallon and the race is 500 miles, the number of gallons each car will take will be:
= 500/6.78
= 73.75 gallons
Since they're 44 cars, the total gallons of fuel will be:
= 44 × 73.75
= 3245 gallons
Since the fuel cost is $1.63 per gallon, the total fuel cost, will be:
= $1.63 × 3245
= $5289.35

Evaluate the function at the given value of x. Round your result to three decimal places.
Function f(x) = 0.2%
Value x = 1.5
Your function is a constant and given the instructions of rounding it seems likely that you have a typo in your question. Anyway here goes the answer.
Since the function is constant no matter the input x the output is always equal to 0.2% because 0.2% is the only value defined in the range of the function.
[tex]f(1.5)=0.2\%=0.002[/tex]
