Answer is A and B

Evaluate the Square root of 9 and 81

9 is the perfect square of 3, so the numerator is 3

81 is the perfect square of 9, so the denominator is 9.

You can simplify the fraction to make 3/9 into 1/3

Which statement about corresponding sides and angles of the two polygons is correct?
lapo4ka [179]
The statement that "The lengths of side SR and side S'R' are in the ratio 1:3" is correct.

The first option is incorrect because, as seen in the graph, the two angles have the same measure.

The second choice and third choices are wrong because the two polygons are different sizes, as stated in the question and as shown in the attached graph.

Therefore, the last selection is the correct option.

Elodia [21]

Answer:

1 week

Step-by-step explanation:

Given:

p = 12w

Where,

w = number of weeks the office has been on the new recycling plan

p = total kilograms of paper recycled.

How many weeks will it take Scott's office to recycle a total of 12 kilograms of paper?

Find w when p = 12

p = 12w

12 = 12w

Divide both sides by 12

w = 12/12

= 1

w = 1 week
