A company has developed a new material for making optical fibre. The critical angle of this material is much greater than that of glass, Lucite, or any other material
currently being used. Will this new product be successful?
a) No, because the materials currently in use work just fine.
b) There is not enough information here to tell.
Yes, because any materials used to make optical fibres should have a large
critical angle.
No, because any materials used to make optical fibres should have a small
critical angle.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
