Answer:
90 degrees
Step-by-step explanation:
A circle has 360 degrees. One degree of a circle, therefore, is 1/360. 1/4 of a circle would equal 90 degrees (1/4 of 360 = 90).

#7. let x = the amount of money he borrows each day. so, the equation would be 8x (because it’s over 8 days, so 8 times x) = 28
so equation: 8x=28
then solve for x, which is 3.5 so $3.50
Answer:
y = 2x-2
Step-by-step explanation:
First find the slope of the line
x+2y=6
2y = -x+6
y = -1/2x +3
This is in slope intercept form ( y = mx+b) so -1/2 is the slope
We want a line that is perpendicular so take the negative reciprocal of the slope
- ( 1/ (-1/2)) = 2
The slope of the perpendicular line is 2
y = 2x+b
Substitute the point into the equation
8 = 2(5) +b
8 = 10+b
-2 =b
The equation of the line perpendicular is
y = 2x-2
