Answer:
The value of k is 60
Option 3 is correct.
Step-by-step explanation:
Given that two parallel lines cut by transversal line
In the figure the two angles are labelled.
we have to find the value of k
Alternate Exterior Angles are those pair of angles on the outer side of each of those two lines but lie on opposite sides of the transversal line.
Here these two angles formed on the outer side and lie on opposite sides
As alternate exterior angles are equal if lines are parallel.
Therefore, the two angles labelled are equal
⇒
Subtract 11 from both sides
Divide by 2 throughout the equation
Hence, the value of k is 60
Option 3 is correct.
Corrected Question
The volume of air inside a rubber ball with radius r can be found using the function V(r) = four-thirds pi r cubed. What does V(5/7) represent?
Answer:
(B)the volume of the rubber ball when the radius equals five-sevenths feet
Step-by-step explanation:
The Volume of a sphere of radius r can be found using the formula:
Therefore comparing the expression: with V(r):
Thus, is the volume of a ball of radius
feet.
The correct option is B.
