Answer:
Step-by-step explanation:
Both parts of the ratio can be divided by 9
81/9 = 9
72/9 = 8
The ratio is 9:8
54/48 is also 9:8
54 / 6 = 9
48/6 = 8
The ratio is 9:8
63:56 is also an answer
63 / 7 = 9
56/7 = 8
The ratio is 9:8
The others don't work. You can just look at them to see why.

Answer:
1 year=3.2%
2 year=6.4%
3 year=9.6%
Step-by-step explanation:
Since the% increases every year
So for the first year=
3.2% of 1
3.2%×1
3.2%
For second year
3.2% ×2
6.4%
For the third year
3.2% × 3
9.6%
Answer:
The ferris wheel travelled 434.717 ft.
Step-by-step explanation:
Assuming that the ferris wheel is a perfect circle, then it's height is the same as the diameter of the circle, therefore it's radius is:
radius = height/2 = 246/2 = 123 ft
The distance travelled by the ferris wheel is the same as the length of the arc created by a angle of (9pi/8). The length of an arc is given by:
length = r*(angle in radians)
length = 123*(9pi/8)
length = 434.717 ft
The ferris wheel travelled 434.717 ft.
Because without place value you might put the decimal in the wrong place and that will effect the answer big time.
