Use a ratio box to solve this problem. There was a total of 520 dimes and quarters in the soda machine. If the ratio of
dimes to quarters was 5 to 8, how many dimes were there?

Dimes:    200

Quarters:     320

Step-by-step explanation:

Construct a table as follows

Item          Dimes          Quarters          Total

Ratio         5                  8                       13

Actual       d                  q                       520

Note that any two ratios of corresponding quantities are the same.

(d/5)=(520/13)=40

d=200

(q/8)=(520/13)=40

q=320

idk lol

step-by-step explanation:

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
