Answer:
B. The ratio of the area of the scale drawing to the area of the painting is 1:16
C. The ratio of the perimeter of the scale drawing to the perimeter of the painting is 1:4
Step-by-step explanation:
The ratio of the area of similar figures/shapes = the square of the ratio of any of their side lengths
Since the scale drawing of the rectangular painting and the actual rectangular painting are similar, therefore,
The ratio of the area of the scale drawing to the painting = 1²:4²
= 1:16
Also, comparing the ratio of the perimeter of the scale drawing to the perimeter of the painting will be the same as the scale factor = 1:4
Answer: Tables, graphes, and equation are realted because they all have the same information but just in diffrent ways. the advantage of a table is that you can see more information and what other possblities and fill in missing spots. graphes you can fid the equation on it by counting on it. The advantage of a equation is that you can solve it and get the answer the fastets

Answer:
an = a(n-1) - 7
Step-by-step explanation:
the second term is smaller than the first term 7.
a20 = a19 - 7
a19 = a18 - 7
=> a20 = (a18 - 7) - 7
Then you can accumalate until a1
-> a20 = a1 - 19*7 = 86 - 19*7 = -47
If you divide 16 by 2 you get 8, so, 8 teams payed $50, while the other half payed $60.
Hope this helps. ^_^
(If you're gonna add them up it's 8x60=480 + 8x50=400=880) :P
