Answer:
67.029 cm ³
Step-by-step explanation:
Volume of cone = ¹/³ πr²h
π= 3.142 , r = diameter /2 so r =2cm , height (h) = 16cm
so V = ¹/³ π x (4) x 16
V = 62.029cm³
2x + x = 54 wher x = number of girls
3x = 54
x = 18
18 girls
Answer:
The graph increases then decreases
Step-by-step explanation:
If you look at point G it is increasing until it gets to the x value of 0. From there on it is decreasing to K.
Answer:
y = - 3x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (2, - 2) ← 2 points on the line
m =
=
= - 3
Note the line crosses the y- axis at (0, 4) ⇒ c = 4
y = - 3x + 4 ← equation of line
