The base of a cube is parallel to the horizon. If the cube is cut by a plane to form a cross section, under what circumstance wo
uld it be possible for the cross section be a non-rectangular parallelogram?
2 answers:
This question has this set of answer choices:
a) when the plane cuts three faces of the cube, separating one corner from the others
b) when the plane passes through a pair of vertices that do not share a common face
c) when the plane is perpendicular to the base and intersects two adjacent vertical faces
d) when the plane makes an acute angle to the base and intersects three vertical faces
e) not enough information to answer the question
The right answer is the first choice: a) when the plane cuts three faces of the cube, separating one corner from the others
You can see a picture of this case in the figure attached: as you can see the cross section (in pink) is a triangle.

It is given in the question that
The temperature measured in Kelvin (K) is the temperature measured in Celsius (C) increased by 273.15. This can be modeled by the equation
To solve for C, we need to get rid of 273.15 and for that we do subtraction, that is
Correct option is the first option .
Answer: a) are needed to travel 8 miles
b) Town X and town Y are 15 miles apart.
Step-by-step explanation:
Given : Gasoline used to travel 5 miles = 3t gallons
a) To find: Gasoline used to travel 8 miles = ?
Using unitary method:
If Gasoline used to travel 5 miles = 3t gallons
Thus Gasoline used to travel 8 miles =
are needed to travel 8 miles
b) when 3t gallons of gasoline are used , distance covered = 5 miles
Thus when 9t gallons of gasoline are used , distance covered =
Thus town X and town Y are 15 miles apart.
The correct answers are:
The slope of the line is 4.
A point on the line is (−5, 56)
Step-by-step explanation:
Given equation is:
The slope-intercept form is:
Comparing both equations we get
m = 4
The point is (-5,56)
So, the correct answers are:
The slope of the line is 4.
A point on the line is (−5, 56)
