X^3 = 216
this means that
x = 216^1/3
x = 6 (real solution)

x = -3 -3^(3/2)i (imaginary solution)
x = -3 +3^(3/2)i (imaginary solution)

Find the four arthmetic means between -3 and 46
Citrus2011 [14]

Answer:

6.8, 16.6, 26.4, 36.2

Step-by-step explanation:

Let's write the sequence, d is the common difference:

- 3, - 3 + d, - 3 + 2d, -3 + 3d, - 3 + 4d, 46

Therefore 46 = -3 + 5d

5d = 49

d = 49/5 = 9.8

So the first arithmetic mean is  -3 + 9.8 = 6.8.  and the second is -3 + 2(9.8) = 16.6...

They are:

6.8, 16.6, 26.4, 36.2.

Suppose you have $20 to spend on party decorations. Balloons are $0.05 each, streamers are $0.25 each, and noisemakers are $0.40
sergejj [24]

[C] 0.05b + 0.25s + 0.4n = 20

b = balloons

s = streamers

n = noisemaker

Since they already give us the price of each item we just need to add a variable at the end of each one since we don't know how many of each item is bought. Adding the costs of all the party supplies should not go over $20. We can automatically eliminate B and D. We can also eliminate A because the prices of each item are incorrect. Therefore, C is the correct answer.

Best of Luck!
