Answer:
4/3
Step-by-step explanation:
If the ratio between the volumes of the first and the second cube is 64, the ratio between the sides is the cubic root of the ratio between the volumes, so:

![s1 / s2 = \sqrt[3]{64} = 4](https://tex.z-dn.net/?f=s1%20%2F%20s2%20%3D%20%5Csqrt%5B3%5D%7B64%7D%20%20%3D%204)
Doing the same for the second and third cubes, we have:

![s2/ s3 = \sqrt[3]{1/27} = 1/3](https://tex.z-dn.net/?f=s2%2F%20s3%20%3D%20%5Csqrt%5B3%5D%7B1%2F27%7D%20%20%3D%201%2F3)
So the ratio of the first cube side and the third cube side is:

Answer:
The current price index number is $604.2.
Step-by-step explanation:
The index value is the ratio between the current value and the reference value, multiplied by 100.
In this problem, we have that:
Current value = $3.48
Reference value: $0.576
Index price = (3.48/0.576)*100 = $604.2.
The current price index number is $604.2.
Answer:
360
Step-by-step explanation:
Six letters in twelve with a repeated e would be 6! ÷ 2
Original debt = $589
APR = 29.99%
The monthly rate is 0.2999/12 = 0.02499
After 1 month:
Amount owed = 589*1.02499 = $603.72
5% payment = 0.05*603.72 = $30.187
New balance = $603.72 - 30.187 = $573.53
After 2 months:
Amount owed = 573.53*1.02499 = $587.87
5% payment = 0.05*587.87 = $29.39
New balance = 587.87 - 29.39 = $558.48
After 3 months:
Amount owed = 558.48*1.02499 = $572.44
5% payment = 0.05*572.44 = $28.62
New balance = 572.43 - 28.62 = $543.82
Answer: $543.82
When the rock hits the ground, y = 0
-.005x^2 +0.41x -5.1 = 0
Multiply equation by (-200)
x^2 -82x +1020 = 0
Use quadratic formula:

Since the ball is initially below the ground, on its way up it will reach the point where y=0 but still be in the air, therefore the ball lands the second time y=0 or when x is larger.
