The Solution:

Given:

Center = (0,0)

Point A = (-5,2) being a point on the circle.

We are required to check if point P = (2,-5) is on the circle.

Solving the given problem graphically, we have:

From the above graph, it is clear that point P(2,-5) is a point on the circle.

a class has 60 students.Given that 85% passed a science test. Find the number of students who failed and then convert o %
Vanyuwa [196]

Given:

Total students = 60

Student passed = 85%

To find:

The number of students who failed and  then convert it in %.

Solution:

We have,

Number of passed student = 85% of Total students

                                            = \dfrac{85}{100}\times 60

                                            = 51

So, number of passes students is 51.

Number of students who failed = Total students - Passes students

                                                    = 60-51

                                                    = 9

So, number of students who failed is 9.

\text{Fail}\%=\dfrac{\text{Failed students}}{\text{Total students}}\times 100

\text{Fail}\%=\dfrac{9}{60}\times 100

\text{Fail}\%=15

Therefore, 15% students fail in the test.

The ratio of art class to music class is 4:3. If there is 8 more students in art class, how many students are in music class
pishuonlain [190]

Answer:

9 students in music class.

Step-by-step explanation:

In art there are 4 and since there are 8 more 8 + 4 = 12. so there are 12 in Art.

4 x _ = 12. —> 4 x 3 = 12.
so we need to do the same for music class.

For music there are 3.
so we multiply by 3 like we did with the 4.

3 x 3 = _ —> 3 x 3 =9.
so there are 9 students in music class.
