Answer:
They had 4 large popcorn and 10 large fountain drinks
Step-by-step explanation:
The picture of the question in the attached figure
I think the price of the large popcorn is $7.50 and the price of the large fountain drink is $5.50 (The picture is not clear)
so
Let
x ----> the number large popcorns
y ----> the number of large fountain drinks
we know that
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system of equations is the intersection point both graphs
using a graphing tool
The solution is the point (4,10)
see the attached figure
therefore
They had 4 large popcorn and 10 large fountain drinks
The <u>correct answer</u> is:
D) <span>when the plane makes a narrow angle with the base.
Explanation:
If a cross section of a prism is taken <u>parallel</u> to the base, the cross section will be the <u>same shape</u> as the base. In this case, it will be a 9 sided polygon.
If a cross section of a prism is taken <u>perpendicular</u> to the base, the cross section will be a <u>rectangle</u>, no matter how many edges the cross section goes through.
The only way to get a cross section with more sides than the original figure is to take a slant cross section, or one with an angle other than 90</span>° or 180° to the base. This makes D our only option.
Answer:
(0, 1)
Step-by-step explanation:
