It took peri 8 games to score 30 points. At that rate how many games will it take her to score 45 points

12 games

Step-by-step explanation:

Assuming that her rate of point scoring stays the same

We can use a ratio to solve

8 games            x games

=

30 points         45 points

Using cross products

8 * 45 = 30x

Divide each side by 30

360/30 = 30x/30

12 =x

12 games

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

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
