Answer:
-11
Step-by-step explanation:
Get like terms on the same side
18y - 14y = -21 -23
Do the math
4y = -44
Divide both sides by 4
y = -11
The volume of the sphere is 2308.4 mm³
<h3>Calculating the volume of a Sphere</h3>
From the question, we are to determine the volume of the sphere
The volume of a sphere is given by the formula
Where V is the volume
and r is the radius
From the given information,
Diameter, d, of the sphere = 16.4 mm
r = 16.4/2
r = 8.2 mm
∴ 
V = 2308.394
V ≅ 2308.4 mm³
Hence, the volume of the sphere is 2308.4 mm³

Two angles that are supplements add up to 180°.
"The angle" is five times its supplement.
If I call the supplement 'S', then 'the angle' = 5S .
S + 5S = 180°
Combine like terms: 6S = 180°
Divide each side by 6 : S = 30°
The supplement of 'the angle' = 30°.
That's one of the choices.
"The angle" = 5S = 150°.
That's NOT one of the choices.
Answer:
4). 47 - 29i
Step-by-step explanation:
(5+√-36)*(1-√-49)=5*1 -5√-49+1*√-36 -√-36√-49 = 5-5*7i +6i-6i*7i=
=5-35i+6i-42(-1)=5+42-41i= 47 - 29i
