The two pentagons seen below are similar figures. What is the scale factor from the large pentagon on the right to the small
pentagon on the left? The pentagons are not drawn to scale.

Answers

Answer:

9.1

Step-by-step explanation:

For scale factor you divide one of the shape dimensions by the other one.

like if you knew the width or something of both of them you divide that one by the other one. So I chose:

                            91 divided by 10 = 9.1

                         81.9 divided by 9 = 9.1

                        54.6 divided by 6 = 9.1

          So the answer is 9.1 no matter what you choose for this problem.

x = 13

Step-by-step explanation:

Now since the lines are parrarel, the intersection points are alternate to each other. Therefore, A = B.

Solve:

8x + 2 = 14x - 76

2 + 76 = 6x

78 = 6x

x = 13

Answer:

Both are congruent meaning they have to equal each other.   answer:  13=x

Step-by-step explanation:

8x+2=14x-76

-8x      -8x

  2=6x-76

+76     +76

78=6x

78/6=6x/6

13=x

You would put it back into one of the equations to fin dthe actual angle.

Answer:
y= 12x-16
Step-by-step explanation:
Given that you have a slope of 12 and a point of (3, 20), you are most obligated to using the Slope-Intercept form, or y=mx+b.
What this allows you to find is the y-intercept if your line has one. You take your point, (3,20), and you insert the values at the appropriate places. You should now have 20=12(3)+b. You will then solve for b by multiplying 12 and 3 to get 36 and subtract that from both sides of the equal sign. You should have 20-36=b. 20-36 is -16, which is your y-intercept.
Your answer would be Y=12x-16

Answer:

15/32

Step-by-step explanation:

Answer: (3/8 + 1/4) x 3/4 = 15/32.

Step-by-step explanation:

Let's first solve the ().

3/8 + 1/4 can be turned into 3/8 + 2/8, which equals 5/8.

(5/8) x 3/4

5/8 x 3/4

Finally, let's do 5/8 x 3/4! You will get 15/32.

So, (3/8 + 1/4) x 3/4 = 15/32.
