Step-by-step explanation:
<em>The question is incomplete as the polygon A (and other possible polygons to select from) are not given. So, I will answer on a general term.</em>
<em></em>
Assume that Polygon A is a rectangle of dimension 2ft by 5ft.
Possible scaled copies can be gotten by multiplying the dimension of A by the same scale factor.
Take for instance, the scale factor k is:
A scaled copy of polygon A (say polygon B) is: 6ft by 15ft
This is gotten by:
The area of A is:
The area of B is:

<u></u>
<u>Comparison</u>
The area of B is greater than the area of B.
<em>This method can be applied to scale factors</em>

Answer:
1.) 3/4
2.) 44/5 or 8 4/5
3.) 17/6 or 2 5/6
Step-by-step explanation:
1.) 5/16 ÷ 5/12
To divide a fraction by another fraction, reciprocate (put the numerator to denominator and vice versa) the divisor then change the sign to multiplication:
5/16 × 12/5
5 × 12 / 16 × 5
Cancel out 5 since both numerator and denominator has it:
12 / 16
Divide both by 4:
12 ÷ 4 / 16 ÷ 4
3/4
2.) 3 1/5 • 2 3/4
You have to convert the fractions first to improper fractions by multiplying the denominator to the whole number then adding the numerator to the product:
3 1/5 = 3×5 + 1 = 16/5
2 3/4 = 2 × 4 + 3 = 11/4
Now you can multiply the numerator to numerator then denominator to denominator:
Since 16 is a factor of 4, you can cancel it out, which leaves 4:
16 / 5 × 11/4
4 × 11 / 5 × 1
44/ 5
3.) 6 3/8 ÷ 2 1/4
Convert to improper fraction:
6 3/8 = 6× 8 + 3 = 51/8
2 1/4 = 4 × 2 + 1 = 9/4
(51 × 4)/ (9×8)
51 × 1/ 9× 2
51 / 18
Divide by 3:
17/6
Answer: m>50
Step-by-step explanation:
Hi, to answer this question we have to write an inequality:
The amount charged by company A (120) must be less (<) than the fixed amount charged by company B (75), plus the product of the cost per mile driven (0.90) and the number of miles driven (m).
120 < 75+ 0.90m
Solving for m:
120-75<0.90m
45<0.90m
45/0.90 <m
50<m
Company A charges less than Company B when m > 50.
Feel free to ask for more if needed or if you did not understand something.
