Answer:
150
Step-by-step explanation:
Answer
m= 1/2
Step-by-step explanation:
Formula for slope = change in y divided by the change in x
Y2 - Y1 = 6 - 7 = -1
X2 - X1 = 2 - 4 = -2
m= -1 divided by -1 = 1/2 or 0.5
Answer:
$102.00
Step-by-step explanation:
$120.00 x .15=$18.00
$120.00 - $18.00=$102.00
Answer:
81 degrees
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
20 = 2*pi*r
Divide each side by 2pi
20/2pi = 2*pi*r/2pi
10/pi =r
We know the arc length can be found by
s =r theta where theta is in radians
9/2 = 10/pi *theta
Multiply each side by pi/10 to isolate theta
9/2 * pi/10 = pi/10 *10/pi *theta
9*pi/20 = theta
We need to convert to degrees
9*pi/20 * 180/pi
81 degrees
