Answer:
B.
Step-by-step explanation:
I'm not sure how to answer the 2. question
Total=28
fantail (f)=comets (c)-4
comets=c
Fantails + comets =28
c-4 +c=28
2c-4=28
2c-4+4=28+4
2c=32
2/2c=32/2
c=16
Answer:
0.375
Step-by-step explanation:
just use a calculator to divide 3 by 8 to find the decimal form
hope this helps :)

<em>Additional comment</em>
z = -2. ∛z will be three points in the complex plane on a circle of radius ∛2 at angles ±π/3 and π radians (±60° and 180°). That is, the real cube root of -2 is -∛2.

Answer:
Step-by-step explanation:
The parallel lines divide each transversal proportionally.
x/30 = 15/26
x = 30(15/26) ≈ 17.3
__
y/16.5 = 26/15
y = 16.5(26/15) = 28.6
