Formula: Y=kx or y=ax or Y/x=a
K=12 k is also the slope!
Slope=12
Y=6
So If you plug in these values you get:
6=12x
Answer:
X=0.5 or 1/5
Answer:
A) Positive
B) Positive
C) None
D) Positive
Step-by-step explanation:
:)
Hourly wage before raise= $12.25 - $0.75 = $11.50. Marietta's hourly wage before the raise was $11.50
-2x + 3a - 6 - 5x - 7a....combine like terms
-7x - 4a - 6 <==
The surface area of the sphere is given by the equation
,
where A is the surface area and r is the radius.
We want to find the volume of the sphere, which is given by the equation
,
where V is the volume and r is the radius.
Looking at these equations, we see that they both involve the sphere's radius. If we know what r is, we can calculate the volume.
We know that the sphere's surface area is . Plugging that in for A in the surface area equation, we get
, then divide by
, then divide by 4
, then take the square root of both sides
So the radius of the sphere is 3. Plugging this into the volume equation,
, simplify terms
, multiply by 27
So the volume of the sphere is .
