HELP HELP HELP THANKS:) Under certain conditions, cane sugar in water is converted into dextrose at a rate
proportional to the mass of sugar unconverted. Write out the differential equation concerned.
If there are 100 g of sugar at time t = 0 and 12 g of it are converted into dextrose during the
first 30 minutes, find the amount converted after 2 hours.​

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

i think its 7.6
