The scale factor of the Reba's drawing is 9/84, 3/28
Step-by-step explanation:
The scale factor is the ratio between the two corresponding sides of the figure. The point worth noting in computing the scale factor is that both sides must have similar units of dimension while using for comparison purpose.
Given the scale used by Reba is 9 inches to 7 feet
Since both the units are different, we have the option to either convert inches to feet or vice versa
We proceed with converting feet to inches
We know that 1 foot equals to 12 inches. Hence 7 feet would equal 84 inches.
Now scale factor= first dimension/ corresponding dimension
Scale factor= 9/84 which can be reduced to 3/28

Answers:
11. 48%
12. 25%
13. 36%
15. 93%
16. 99%
17. 0.16%
18. 160%
19. 85%
Work for 19:
The chart is incorrect because it calculates 40% of 34 instead of 40 percent of x (we got 85% for our answer but I'm using x as the unknown number) results in the number of 34.
Percentage of 40% of what number = 34?
40% of what number = 34 is equivalent to: 40% × ? = 34
--------------------------
40% × ? = 34
? =
34 ÷ 40% =
34 ÷ (40 ÷ 100) =
(100 × 34) ÷ 40 =
3,400 ÷ 40 =
85
Proof:
If 40% × 85 = 34 =>
Divide 34 by 85...
... And see if we get as a result: 40%

Answer:B
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>Given functions</u>
- f(x)= -3/4x
- g(x)= -5x
- h(x)= 5/7x
- j(x)= 11/3x
To compare steepness we'll compare absolute values of slopes
The steepness increases as the slope increases
<u>The slopes are </u>
<u>Comparing the fractions</u>
- 3/4 = 21/28, 5/7 = 20/28, so 3/4 > 5/7
And
<u>So the order is </u>
<u>As functions, the order is</u>
