Given:
Original figure and enlarged figure
To find:
Which ratios can be used to find the scale factor.
Solution:
Scale factor is the ratio of comparing the corresponding sides of two figures.
Option A:
Length of enlarged side = 6.5
Length of original side = 3.25
It is correct.
Option B:
3.25 is the length of original figure. But here it is mentioned in enlarged.
So, it is not correct.
Option C:
Width of enlarged side = 3
Width of original side = 1.5
It is correct.
Option D:
1.5 is the width of original figure. But here it is mentioned in enlarged.
So, it is not correct.
Option E:
1.5 is the width of original figure. But here it is mentioned in enlarged.
So, it is not correct.
Therefore the ratios can be used to find the scale factor are:
<u>Answer: </u>
If they worked together it would take 4 hours for the machines to produce 100 widgets
<u>Step-by-step explanation:</u>
w = widgets hr = hour ph = per hour
Old machine - 50w = 5hr = 10ph
New machine - 30w = 2hr = 15ph
Old machine - 20w = 2hr
New machine - 30w = 2hr
<h3>Together - 50w = 2hr x 2 </h3><h3> Final: 100w = 4hr</h3>

Step-by-step explanation:
Answer:
x < - 6 or x > 6
Step-by-step explanation:
Inequalities of the type | x | > a, always have solutions in the form
x < - a or x > a
given 4| x + 2 | > 16 ( divide both sides by 4 )
| x + 2 | > 4 ← in the above form, hence
x + 2 < - 4 or x + 2 > 4 ( subtract 2 from both sides of both inequalities )
x < - 6 or x > 6 ← solution
