Figure B is a scaled copy of Figure A

What is the scale factor from Figure A to Figure B?

Answers

Answer:

[tex]1/2[/tex]

Step-by-step explanation:

Because they are scaled copies, the ratios of the sides are equal.

Figure A has a base of 6 units by inspection.

Figure B has a base 3 units by inspection.

So, the scale factor from Figure A to Figure B is [tex]3/6=\boxed{1/2}[/tex] and we're done!

The scale factor from Figure A to Figure B is 1/2

What is the scale factor from Figure A to Figure B?

Figure A:

Base = 6 units

Height = 4 units

Figure B:

Base = 3 units

Heights = 2 units

Using Base of the shape:

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape

= 3 units / 6 units

= 1/2

Using Height of the shape:

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape

= 2 units / 4 units

= 1/2

Hence, 1/2 is the scale factor from Figure A to Figure B.

Step-by-step explanation:

Answer:

40° and 140°

Step-by-step explanation:

let one angle be x then the other is 3.5x

A linear pair sum to 180° , then

x + 3.5x = 180

4.5x = 180 ( divide both sides by 4.5 )

x = 40 and 3.5x = 3.5 × 40 = 140

The angles are 40° and 140°

The answer is t = 17

Step-by-step explanation:

Sum of angles on a straight line = 180⁰

(2t -7) + 90 + 49= 180

(2t -7) +139 = 180⁰

2t -7) = 180 - 139

2t - 7 = 41

2t = 41 - 7

2t = 34

Divide both sides by 2

t = 17

Write an equation of the line that passes through the point (4, –5) with slope 2.
A. y−4=−2(x+5)
B. y+5=2(x−4)
C. y−4=2(x+5)
D. y+5=−2(x−4)

Answers

Answer:

The correct choice is option B. y + 5 = 2(x−4)

Step-by-step explanation:

slope = 2

y = mx + b

-5 = 2(4) + b

-5 = 8 + b

-8    -8

------------------

-13 = b

y = 2x - 13, in other words --> y + 5 = 2(x−4)

So, y + 5 = 2(x − 4) is the equation of the line that passes through (4, -5).
