For a science experiment, a teacher needs 80 milliliters of venigar for each pupil. There are 30 pupile in a class. Venigar comes in 1000 milliliters bottle. How many bottles of venigar were needed.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

vertical=18cm horizontal=18cm hypotenuse=25.5
