Answer:
The circumference of this circle is feet.
Step-by-step explanation:
Circumference of a circle =
Where,
r is the radius of the circle.
Therefore, we can find the circumference of the circle by substituting the values to the equation:
The circumference of this circle is feet. (Rounded to the nearest tenth)
Answer:
Step-by-step explanation:
Let the numbers be x,y, where x>y
The geometric mean is
The Arithmetic mean is
The ratio of the geometric mean and arithmetic mean of two numbers is 3:5.
We can write the equation;
or
l
and
or
Make y the subject in equation 2
Put equation 3 in 1
When x=1, y=10-1=9
When x=9, y=10-9=1
Therefore x=9, and y=1
The ratio of the smaller number to the larger number is
Answer:
Option D
Step-by-step explanation:
A). From the graph attached,
Arrow AB represents the RISE and arrow BC represents the RUN.
B). RUN from point A to B (Horizontal distance) = 2 units
Rise from point A to B (Vertical distance) = -4 [Since, downwards arrow represents negative notation]
Slope of the line segment AB =
=
= -2
Therefore, slope of the line = slope of the line segment AB = -2
Option D will be the correct option.
