Answer:
0.13 ft/min
Step-by-step explanation:
We are given that
We have to find the increasing rate of change of height of pile when the pile is 12 ft high.
Let d be the diameter of pile
Height of pile=h
d=h
Radius of pile,r=
Volume of pile=
h=12 ft
Substitute the values
Answer:
(A) x=40
Step-by-step explanation:
Given: It is given that m is parallel to n.
To find: The value of x.
Proof: It is given that m is parallel to n, from the figure it can be seen that 105° and (3x-15)° forms alternate exterior angles which are equal in measure because m is parallel to n.
Thus,
⇒
⇒
⇒
⇒
Thus, the value of x is 40, hence option A is correct.
