Answer from: juicyx39

The scale factor from Figure A to Figure B is 0.5

since the scale factor is less than 1 so the figure is contracted.

Given there are two figures of rectangles

Figure A and figure B

We are asked the scale factor from figure A to figure B

Hence the final figure is figure B and the initial figure is Figure A

The scale factor of any figure is defined as formulated in equation (1)

$\rm Scale \; Factor = \dfrac{Final\; Dimension }{Initial\; Dimension } .........(1)$

According to the given figures we can observe that

Length of pair of one parallel sides of figure A is drawn using 4 squares while the same for figure B uses only 2 squares.

So from the equation (1) we can write that

$\rm Scale \; factor = \dfrac{Dimension \; of \; figure\; B }{Dimension \; of \; figure\; A } = \dfrac{2 }{4 } = \dfrac{1}{2} =0.5$

So the scale factor from Figure A to Figure B is 0.5

since the scale factor is less than 1 so the figure is contracted.

Answer from: nenelacayo07

The scale factor from Figure A to Figure B is 0.5

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is the scale factor

Let

z-----> the scale factor

In this problem

$z=\frac{hB}{hA}$

substitute values

$z=\frac{2}{4}=0.5$

the scale factor is less than 1

therefore

is a reduction

a) one student is chosen from classroom a, then a student is chosen from classroom b.

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b. this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes. this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes. this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes. this makes them dependent events.

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
