Combinations of 7 taken 4 at a time.
C (7,4) = 7! /[ 4!(3!)]
7 x 6 x 5 = 210
210 divided by 3 = 70
70 divided by 2 = 35
I got -19/655 and i know for sure this isnt the correct answer.
I) there are 360 degrees in a circle. So subtract all the numbers from 360 to get the angle for econ.
That angle is 65 degrees
ii) If 95 degrees represents 228 books, then 360 degrees represents "x" (total) books. So we have an equation:
<u>95</u> = <u>360</u>
228 x
Solve for x, and we get x = 864
iii) The percentage is 80 degrees out of 360 degrees or 2/9 or roughly 0.222 or 22.2%

Answer: 16 units
Step-by-step explanation:
Point A and Point B are 5 units apart on the x-axis.
Since this is a rectangle, the opposite side is equivalent.
Point A and Point C are 3 units apart on the y-axis.
Same thing applies for these points.
5+5+3+3=16 units
