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.

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?

Answers

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

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

Answers

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.

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

Answers

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

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

Answers

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]

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

Answers

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

In which sentence does the author most clearly define his argument?adapted from The Goal of Sending a Man to the Moonby John F. Kennedy If we are to win the battle that is now going on around the world between freedom and tyranny, the dramatic achievements in space which occurred in recent weeks should have made clear to us all the impact of this adventure on the minds of men everywhere. Since early in my term, our efforts in space have been under review. With the advice of the Vice President, we have examined where we are strong and where we are not, where we may succeed and where we may not. Now it is time to take longer stridestime for a great new American enterprisetime for this nation to take a clearly leading role in space achievement. This in many ways may hold the key to our future on earth. Recognizing the head start obtained by the Soviets with their large rocket engines, we nevertheless are required to make new efforts on our own.For while we cannot guarantee that we shall one day be first, we can guarantee that any failure to make this effort will make us last.We take an additional risk by making it in full view of the world, but this very risk enhances our stature when we are successful.We go into space because whatever mankind must undertake, free men must fully share. I therefore ask the Congress, above and beyond the increases I have earlier requested for space activities, to provide the funds which are needed to meet the following national goals: First, I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space. None will be so difficult or expensive to accomplish.In a very real sense, it will not be one man going to the moonif we make this judgment affirmatively, it will be an entire nation.For all of us must work to put him there. Secondly, an additional 23 million dollars, together with 7 million dollars already available, will accelerate development of the Rover nuclear rocket.This gives promise of some day providing a means for even more exciting and ambitious exploration of space.This will perhaps go beyond the moon, perhaps to the very end of the solar system itself. Third, an additional 50 million dollars will make the most of our present leadership, by accelerating the use of space satellites for world-wide communications. Fourth, there will be an additional 75 million dollarsof which 53 million dollars is for the Weather Bureau. This will help give us at the earliest possible time a satellite system for world-wide weather observation. Let it be clear that I am asking the Congress and the country to accept a firm commitment to a new course of actiona course which will last for many years and carry very heavy costs: 531 million dollars in fiscal '62an estimated seven to nine billion dollars additional over the next five years. If we are to go only half way, or reduce our sights in the face of difficulty, in my judgment it would be better not to go at all. what is the quotient of the sum of x plus 4 and 2 What helps the stem of the Bramble to grip and move over the ground
