Answer:
0/6 <--------------------------
There's not enough info to answer this question. How far is the other gas station? And how many gallons of gas does she use for the distance?
Answer:
No. It is an inverse variation.
Step-by-step explanation:
6= xy
Making y the subject of formula:

For a direct variation, the equation would be in the form of y=kx, where k is a constant.
However, the equation above is in the form of
.
Thus, 6=xy does not show direct variation.
Answer:

Step-by-step explanation:
we know that
If the base of the solid is a circle and all plane sections perpendicular to a fixed diameter of the base are equilateral triangles
then
The solid is a cone
The volume of a cone is equal to

we have

Find out the height of the cone
Remember that
If all plane sections perpendicular to a fixed diameter of the base are equilateral triangles
then
The length side of each equilateral triangle is equal to the diameter of the base
Applying the Pythagoras Theorem find out the height of the cone

we have
----> the diameter is two times the radius

substitute and solve for h




Find the volume


assume
