There are 12 students in a class that represent 40 percent of the class. I'm trying to figure out how many students there are for 20%, 60%, 80%, and 100% of the class. PLEASE HELP IM IN A TEST

A multiple of  

5

Explanation:

Percent means "per hundred", expressing a proportion.

The proportion of boys in the class is:

40

100

=

2

⋅

20

5

⋅

20

=

2

5

In other words, for every  

5

students in the class,  

2

are boys and  

3

are girls.

In order that the figure  

40

%

be exact, the number of students must be a multiple of  

5

.

Then the number of boys will be the corresponding multiple of  

2

and the number of girls the corresponding multiple of  

3

.

That is about as much as we can deduce from the question as given.

i just took the test, the correct answer is .. 31.5 in.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
