Answer:
Please look at the image.
I solved this by the information of 6 pages in 12 minutes which means 0.5 or half a page per minute.
Now you know you read half a page in a minute
5 pages in 10 minutes because:
10 × 0.5 = 5
8.5 pages in 17 minutes because:
17 × 0.5 = 8.5
Answer:

Step-by-step explanation:
Given



Required
Determine the hours of practice over 6 days
First, we calculate the hours for the given 3 days.



The hours of practice for the other three days is also 52 hours.
So, the total is:


Answer: The answer is (C) (4,1).
Step-by-step explanation: Given points are A(0,3), B(-1,4) and C(2,-1). Obviously, these points will form a triangle. We need to find the co-ordinates of the point B', which is formed after rotating the figure counter-clockwise 90 degrees.
The point B(-1,4) lies in the second quadrant. After rotating 90 degrees counter-clockwise, the this point will lie in the first quadrant. So, both the x-coordinate and y-coordinate will be positive. Also, the two coordinates will exchange. Please see the attached figure.
Thus, the coordinates of point B' are (4,1).
Hence, (C) is the correct option.
A1=13 and a+1 = an+4
13+1=13n+4
14=17n
