Answer and Step-by-step explanation:
what must be true is that this particular two lines are not a set of PARALLEL lines. When the lines are parallel, the corresponding angles are congruent and the then the pairs of consecutive angles formed are supplementary .
If we are takling about corresponding angles, they will not be congruent if the lines are not parallel
The answer is 9 for this one
Answer:
1
Step-by-step explanation:
Change of Y is 0 and change of x is any number.
0/any number = 0
An hemispherical dome is half a sphere. If the diameter is 60 m, then the radius is 30 m.
We can use differentials to solve this problem because we are adding a thin layer to the original dome, so the volume of the dome in increased by a differential of itself.
This differential volume that the dome is increased is equal to the volume of the coat of paint.
The volume of the dome can be written as:

Now, we can calculate dV as:

Answer: the paint needed for this coat is approximately 7.92 m^3
