Help!! BRAINLIEST TOO!

Answer:

36.5 inches

Step-by-step explanation:

Given

See attachment for the given data

Required

Which length is closest to 4.2lb

The given data is a linear dataset.

So, we start by calculating the slope (m)

m =\frac{y_2 - y_1}{x_2 - x_1}

Pick any two corresponding points from the table

So, we have:

(x_1,y_1) = (8,1.21)

(x_2,y_2) = (12,1.63)

So:

m =\frac{y_2 - y_1}{x_2 - x_1}

m =\frac{1.63 - 1.21}{12 - 8}

m =\frac{0.42}{4}

m =0.105

The linear equation is then calculated using:

y = m(x - x_1) + y_1

This gives:

y = 0.105 * (x - 8) + 1.21

Open bracket

y = 0.105x - 0.84 + 1.21

y = 0.105x + 0.37

To get the length closest to 4.2lb,

we set y = 4.2

Then solve for x

So, we have:

y = 0.105x + 0.37

4.2 = 0.105x + 0.37

Collect like terms

0.105x= 4.2 - 0.37

0.105x= 3.83

Solve for x

x= 3.83/0.105

x\approx 36.5

Figure B is a scaled copy of Figure A.Select all of the statements that must be true:
KatRina [158]

Answer:

B) Figure B has the same number of edges as Figure A

D) Figure B has the same number of angles as Figure A

E) Figure B has angles with the same measures as Figure A

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

If Figure B is a scaled copy of Figure A

then

Figure A and Figure B are similar

therefore

<u><em>The statements that must be true are</em></u>

B) Figure B has the same number of edges as Figure A

D) Figure B has the same number of angles as Figure A

E) Figure B has angles with the same measures as Figure A
