Answer:
1) the set of all points in a plane that are at a given distance from a given point in the plane
2)a chord of a circle that contains the center of the circle
3)circles that have equal radii
4)two or more circles that lie in the same plane an have the same center
5)a segment joining the center of a circle to a point of the circle
The rule is first it adds 2 then 3 so,8,6,9,7,10,12,15
Equation used to solve for the unknown positive integer is
So, Option C is correct.
Step-by-step explanation:
We need to write the equation from the statement given:
<em>Twenty times a square of a positive integer, plus 50 equals negative 40 times the square of the positive integer, plus one-hundred and ten times the positive integer.</em>
Let the number is x
Now, the equation will be:
Simplifying the equation we get:
Equation used to solve for the unknown positive integer is
So, Option C is correct.

Answer:
Option B. 2.75
Step-by-step explanation:
It has been given in the question that a wedge has a width of 2 cm and a slope of 5.5 cm.We have to calculate the mechanical advantage of the given wedge.
We know the formula to calculate the mechanical advantage of the wedge
Mechanical advantage = Length of slope/Thickness of the widest end
= 5.5÷2 = 2.75
Therefore the answer is option B. 2.75
