Answer:
4.5 is the mean/average
Step-by-step explanation:
3+1+5+4+8+6=27
27 divided by 6 = 4.5
A=πr^2, that is for the total area of the circle. However we only want the area of the sector enclosed by 172° so
A=172πr^2/360, since r=12
A=172π*144/360
A=68.8π u^2
A≈216.14 u^2 (to nearest hundredth of a unit)
Answer:
9,720 meters, or 9.72 km
Step-by-step explanation:
Rob runs at a speed of V1 = 3.8 m/s for t1 = one half hour = 30 x 60 = 1,800 seconds.
=> the distance he runs S1 = V1 x t1 = 3.8 x 1,800 = 6,840 meters
He walks at V2 = 1.6 m/s for t2 = 1,800 seconds.
=> the distance he walks S2 = V2 x t2 = 1.6 x 1,800 = 2,880 meters
The total distance he runs and walks S = S 1 + S 2 = 6,840 + 2,880 = 9,720 meters
Answer:
-2
Step-by-step explanation:
x – 2y = 12
-2y = -x + 12
y = 1/2x - 6
Slope in above equation is 1/2. If you want the slope of a perpendicular line take the inverse opposite which makes it -2/1 or just simply -2.
Rewrite the equation with the perpendicular slope:
y = -2x - 6
