A school librarian has enough money to order 8 paperback books at $155 each. If the librarian decided instead to order books with hard covers at $188 each, how many books can the librarian buy?

hi

money he has  :   155 *8  =     800 + 440  =  1240

SO  1240 / 188 ≈ 6.59

so answer  is  6  as you cannot buy half books...

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are
