4(4/5) + √(4/5) + 0.2 - 5(4/5)

= 16/5 + (2√5/5) + (1/5) - 4

= (16 + 2√5 + 1 - 20)/5

= (2√5 - 3)/5 or 0.29442719

A library ordered 956 new books. They ordered 12 times as many mystery books as romance. They ordered 52 more science fiction bo
Nataly_w [17]

Answer:

Romance books ordered =   65

Mystery books ordered  =  775

Science Fiction book  Ordered ≈ 116

Step-by-step explanation:

Total number of books ordered in the library = 956

Let us assume the number of romance books ordered = m

⇒Number of mystery books ordered = 12 x (Number of romance books)

                                                                =  12 x(m)  = 12 m

Also,number of science books ordered = 52 +(Number of romance books)

                                                                    = 52  +   m

Now, according to the question:

Number of { romance books + mystery books + science books} = 956

or, m  + ( 12 m ) +  (52  + m)  = 956

or, 14 m = 956 - 52

or, 14 m = 904

⇒ m =  904/ 14 =  64.6

So, the number of romance books ordered = 64.6 ≈  65

Number  of mystery books ordered  = 12 m =  12 x 64.5  = 775

Number of science fiction book  ordered = = 52 + m =  116.6 ≈ 116

How can an expression or process be determined for an arithmetic sequence?
ElenaW [278]
An aritmetic sequcne is represented as

a_n=a_1+d(n-1)

where
an=nth term
a1=first term
d=common differnce, or how much each term increases by
n=which term



example

1,3,5, etc
first term is 1
common difference is 2 because it increases by 2 each time
so the formula would be
a_n=1+2(n-1)

if we had
5,3,1
first term s 5
common difference is -2 since it goes up by -2 each time
so formula is
a_n=5-2(n-1)



hope this helps
