Ayuda con mi tarea de matemáticas , dice asi : En una biblioteca hay 5 estantes , 2/5 de uno de ellos está ocupado por libros de
laiz [17]

There are 5 shelves in the bookcase.

2/5 of one shelve is occupied.

That would be:

2/5*1/5=2/25 of all shelves

7/2 is more than 1, so it refers to the bookcase instead of one shelve. The same with 11/10.

So the total is:

2/5+7/2+11/10 = 5

So all shelves are completely full.

So there is no room for any other book.

Answer:

Step-by-step explanation:

b/c these are similar triangle we can say this ratio of the two triangles is true

15/x = 31/(44+x)

now just use algebra to solve for x

15*(44+x) = 31x

660+15x = 31x

660=16x

41.25 =x

What is the maximum number of consecutive odd positive integers that can be added together before the sum exceeds $401$
salantis [7]

The maximum number of integers is 27 that can be added together before the summation of the A.P. Series exceeds 401.

According to the statement

We have a given that the maximum sum of the positive integers is 400.

And we have to find the value of n which is a maximum number of integers by which the value of sum become 400.

So, to find the value of the n we use the

A.P. Series'Summation formula

According to this,

S = n (n+1)/2

Here the value of s is 401

Then

S = n (n+1)/2

401 = n (n+1)/2

401*2 = n (n+1)

802 =n (n+1)

n (n+1) = 802

n^2 + n -802 =0

By the use of the Discriminant formula the

value of n becomes n = -28 and n = 27.

The negative value of n is neglected.

Therefore the value of n is 27.

So, The maximum number of integers is 27 that can be added together before the summation of the A.P. Series exceeds 401.
