Iteru [2.4K]

Ok, so I’m guessing that 35% is $140 and that the question is asking to find the total at first.
Basically,
35% -> $140
So we’re gonna find 100%
1%->140 divide by 35 which is 4
100%-> 4 x 100= $400
And that should be your answer:)

Rus_ich [418]

Answer:

Ellipses (special case is called a circle), hyperbolas, parabolas.

Step-by-step explanation:

These are all conic sections.

A conic section is defined by the cross section of a plane and a double-napped cone. There are other special cases called degenerate conics, which are lines and points (occurs when the equation does not follow the usual pattern, however, these are not considered main conics). The main types of conics are: ellipses, hyperbolas, and parabolas.

The illustration below gives more insight into the question.

I hope this helps.
