A medical researcher has two petri dishes containing viruses. Dish A has a population density of 1.2 viruses per square millimeter. Dish A has an area of about 2,826 square millimeters. If both petri dishes have the same population density, approximately how many viruses are in Dish A?

Respuesta :

Answer;

= 3,391 viruses

Explanation;

  • The population density is 1.2 viruses per square millimeter.
  • This means, each square millimeter is occupied by a population of 1.2 viruses.

Therefore; for an area of 2,826 square millimeters, there will be;

  = 2,826 multiplied by 1.2 viruses

 = 2,826 × 1.2

 = 3391.2 viruses,

and since we can have a fraction or decimal virus then the population would be 3391 viruses

Answer: There are 3391.2 viruses in petri dish A.

Step-by-step explanation:

Given statements : The population density is 1.2 viruses per square millimeter.

each square millimeter is representing  population of 1.2 viruses.

There is a directly proportional relation between the area and the population  .

Let x be the population of virus in perti dish A.

Therefore,

[tex]x=1.2\times2826=3391.2\ vruses[/tex]

Hence, there are 3391.2 viruses in petri dish A.
