There are 56 ducks in the pond after a 40% increase
Answer:
C
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 )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, - 1) ← 2 points on the line
m = =
note that the line crosses the y-axis at (0, - 2) ⇒ c = - 2
y = x - 2 ← equation of line

Answer:
Area of wall = 360 ft²
Step-by-step explanation:
Given:
One part of wall (Rectangle) = 16ft x 18ft
Another part of wall (Triangle) = 8ft x 18ft
Find:
Area of wall
Computation:
Area of wall = Area of rectangle + Area of triangle
Area of wall = (l x b) + (1/2)(b)(h)
Area of wall = (16 x 18) + (1/2)(8)(18)
Area of wall = 288 ft² + 72 ft²
Area of wall = 360 ft²
Answer:
The volume of cone A is twice the volume of cone B.
Step-by-step explanation:
The formula that is used to find the volume of a cone is given by :
Where
r is radius of cone and h is height
ATQ,
The radius of the base of cone A is twice as large as the radius of the base of cone B. The height of cone B is twice the height of cone A.
or
Taking ratios of their volume,
So,
The volume of cone A is twice the volume of cone B.
