90 points a geologist studying an ancient riverbed calculates that there are at least 2,000 microfossils in every liter of soil that he collects.
how many liters of soil should he collect if he wants to obtain 7,500 microfossils for his research study? round your answer to the nearest tenth.
a. about 0.3 liters
b. about 2.7 liters
c. about 3.8 liters
d. about 37.5 liters

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
