Over the original price($65.00), $87.75 would be a 35% increase.
Answer:
37.68 units^2
Step-by-step explanation:
Area of whole circle: 50.24 units^2
Area of 1/4 of it: 50.24/4=12.56
50.24-12.56=Area of remaining
Area of remaining=37.68 units^2
Speed = distance / time => time = distance / speed
speed = 3x10^8 x 60 = 180x10^8 m per minute
time = 1.5x10^11/180x10^8 = 150x10^9/180x10^8 = 5/6x10 = 8,3 minutes
Answer:
y= -6x + 39
Step-by-step explanation:
y = 1/6x - 2
to find the equation that is perpendicular to it, there gradients timesed together equal -1
so 1/6 × ? = -1
? = -6
so the start of the equation is,
y = -6x + c
now we need to sub in the coordinates (7,-3) to find the rest of the equation
-3 = -6(7) + c
-3 = -42 + c
39 = c
so the equation is...
y= -6x + 39
