I got question 3 wrong, but it still shows the correct answer for it. If these answers get you a 100, friend me.

10 glasses of juice could be made with 5 carrots, 1,500 orange juice, 2,000 papaya juice.

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
