Answer:
(c) 9 3/5
Step-by-step explanation:
This is a ratio question. We can work with the dimensions as fractions and solve through cross-multiplication.
Dimensions of the first painting:
8/20 in.
Possible dimensions of the second painting:
24/x in.
x/24 in.
There are two options, because the given 24 inches may be either a length or width of the painting.
Now, we can use cross-multiplication to try to find x in both scenarios.
Scenario #1
8/20=24/x
8x=480
x=60 in.
60 in. is not an answer. Let's try the other scenario.
Scenario #2
8/20=x/24
192=20x
9.6 in.=x
9.6 can also be written as 9 3/5, which is option C.

Answer:
I think it's A, either that or D. But i'm pretty sure it's A.
Step-by-step explanation:
Subtract 15 - 4.5 = 10.5 10.5 divided by 2.5 equals 4.2, which equals 4 1 /5.

Answer: d. 0, 6, 18, 36</h3>
================================================
Work Shown:
Plug in n = 1 to find the first term
d_n = 3n(n-1)
d_1 = 3*1(1-1)
d_1 = 0
The first term is 0
Then repeat for n = 2
d_n = 3n(n-1)
d_2 = 3*2(2-1)
d_2 = 6
The second term is 6
We have enough to stop here since the sequence {0, 6, ...} is shown by choice D, while the other answer choices have a different two starting values.
------
If you were to keep going, then it would look like this
Plug in n = 3
d_n = 3n(n-1)
d_3 = 3*3(3-1)
d_3 = 18
The third term is 18
and plug in n = 4
d_n = 3n(n-1)
d_4 = 3*4(4-1)
d_4 = 36
The fourth term is 36.
