Determine the yearly cost
To do this, we multiply the monthly subscription by 12



<em>Hence, the yearly servics cost is $59.88</em>
250 * 0.20 = $50 sale
250 - 50 = $200
You will pay $200 after sale
By definition, the volume of a cone is given by:

Where,
r: radius of the circular base
h: height of the cone
Let's define a variable:
x: diameter of the base
We have then that the radio is:

The height is:

Substituting values:

Rewriting:
Answer:
An expression that represents the volume of the cone, in cubic units is:
Answer:
y = -6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.75y−1.5y+0.5=5
0.75y+−1.5y+0.5=5
(0.75y+−1.5y)+(0.5)=5(Combine Like Terms)
−0.75y+0.5=5
−0.75y+0.5=5
Step 2: Subtract 0.5 from both sides.
−0.75y+0.5−0.5=5−0.5
−0.75y=4.5
Step 3: Divide both sides by -0.75.
Hope this helps!

Plug n = 14 into the formula
= -5(14) + 90
= -70 + 90 = 20
