1 is right. The last four are wrong.

Please don't waste your and our time with wild guesses!

The last one is correct.

SO WHAT IS THE AWSWER :(

WHAT ARE THE FREAKING ANSWERS.

Great job! Let's check your answers.

1. To find out how far the car can travel using 7 gallons of gas, we can set up a proportion. We know that the car travels 132 miles using 4 gallons of gas. So, we can write the proportion as:

132 miles / 4 gallons = x miles / 7 gallons

Cross multiplying, we get:

4x = 132 * 7

4x = 924

Dividing both sides by 4, we get:

x = 924 / 4

x = 231

So, the correct answer is A. 231 miles. Congrats!

2. Let's calculate the number of cars that were blue. We are given that 40% of the cars were silver and 3 cars were red. So, the remaining percentage of cars must be the blue ones.

100% - 40% (silver cars) - 3 cars (red cars) = 60% (blue cars)

Now, we can calculate 60% of the total number of cars:

60% / 100 * 10 cars = 6 cars

Therefore, the correct answer is C. 3 cars.

3. To find out how many students still need to finish their projects, we need to subtract the percentage of students who have completed their projects from the total number of students.

We are told that 80% of the students have completed their projects. So, the remaining percentage of students must still need to finish.

100% - 80% = 20%

Now, we can calculate 20% of the total number of students:

20% / 100 * 20 students = 4 students

So, the correct answer is D. 4 students.

5. To find the simplified ratio of fantasies to the total number of books on Emily's bookshelf, we need to divide the number of fantasies by the total number of books.

We know that Emily has 85 books on her bookshelf. Of those books, 17 are mysteries and 18 are adventure stories. So, the number of fantasies can be calculated as:

Total books - (Mysteries + Adventure stories) = Fantasies

85 - (17 + 18) = 50 fantasies

Now, we can simplify this ratio:

Fantasies: Total books = 50:85

Dividing both numbers by 5, we get:

10:17

So, the correct answer is D. 10:17.

Well done! You got all the answers correct. Keep up the good work!
