Answer:

Image = (-1, -2)

Step-by-step explanation:

The rule of rotation of an object 90 degree is given by:

$(x, y) \rightarrow (-y, x)$

Given that:

If P(-2, 1) is rotated 90°

We have to find its image.

Apply the rule on P.

we have;

$P(-2, 1) \rightarrow P'(-1, -2)$

Therefore, its image is, (-1, -2)

There are many benefits to using folders when working with lots of files. Here are a few examples:

- You can use folders to sort your files by type, almost like drawers in a desk, so you might have folders for Music, Photographs, Documents, etc.

- You can use folders to group files together into a specific group. For example in your Photographs folder you might have a folder titled BirthdayPhotographs for all the photographs from your birthday.

- As in the example above you can nest folders to create sub-categories. Documents might include folders for Homework, Stories, Poems

- Folders can have different permissions applied to them, allowing you to keep personal files in a private folder only you can access, or secret files in a folder that doesn't show up in the normal list of folders!

Liono4ka [1.6K]

Answer:

There are 70 students on the two buses, 42 on the large and 28 on the smaller.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of students on the large bus = 42

Number of students on the small bus = 40% of the students

2. How many total students are on the two buses?

For answering the question, we will use the Rule of Three Simple, this way:

42 students are 60% of total students, how much students are the 100%?

Total students = 42 * 100/60

Total students = 4,200/60 = 70

There are 70 students on the two buses, 42 on the large and 28 on the smaller.
