Step-by-step explanation:
Jacob has 75 cookies.
He gave 2 cookies to each student.
Complete the table:

Let n be the number of students. After nth student arrived Jacob had left

cookies.
This is an arithmetic sequence with

Thus,

Alright, lets get started.
Suppose total number of dancers in school = x
We have given in question, 42 % of total dancers are ballet dancers.
So, we could find number of ballet dancers by finding 42 % of total dancers.
Number of ballet dancers = x * 42 %
Number of ballet dancers = x * 42/100 = 0.42 x
As per given in question, there are 63 ballet dancers in school.
Which means 0.42 x = 63
Dividing 0.42 from both sides
0.42 x / 0.42 = 63 / 0.42
x = 150
Hence number of total dancers in school = 150 : Answer

This will prove my answer correct.
Answer:
-0.25
Step-by-step explanation:
Coordinates of C = 
Coordinates of D = 
Let Coordinates of A= (x,y)
Since A point is located 1/4 the distance from C to D
So the remaining distance from point A to D is 3/4
Thus the ratio of CA : AD = m:n=1:3
Now to find points of A we will use section formula i.e.


Substituting the values:



Thus Find the x value for the point that is 1 over 4 the distance from point C to point D is -0.25
Hence option a is correct
