Answer:
Step-by-step explanation:
Using the area formula of a cone, find the height first.
Solve for h,
Begin by dividing by
Subtract r.
Square both sides.
Subtract
Extract the square root.
Plug in your values.

Now, to find the slant height use this formula:
A. fixed costs of 18,000 and then 40 per canoe
c(x) = 18000 +40x
B) sell price is 160 per canoe, so r(x) = 160x
C) break even, set both a and b equal to each other and solve for x
18000 + 40x = 160x
subtract 40x from each side:
1800 = 120x
divide both sides by 120
x = 18000 / 120 = 150 canoes
break even means the money coming in equals the money going out
A :
1 cm = 16.5 m
1 m = 1 : 16.5 = 0.060606 cm
480 * 0.060606 = 29.09088 cm ( on the scale drawing )
B :
1.5 in = 0.5 ft
6 ft = 0.5 ft * 12
12 * 1.5 in = 18 inches
Answer:
C
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 3) and (x₂, y₂ ) = (2, - 3) ← 2 points on the line
m = = = - , thus
y = - x → C
