Oh yay, proportional thinking! (Vicious sarcasm). Alright, let's do this:

<span>Volume of the cylinder = </span><span>π(h)r^2
New volume = </span><span>π(h/3)(4r)^2
= (1/3)</span><span>π(h)(16r^2)
=16*(1/3)</span><span>π(h)r^2
=(16/3)</span><span>π(h)r^2

Therefore, it's D. Though it's spelled pi, and you should really use the ^ symbol. </span>

12x15y=4140; x+y= ? <br> solve.
Semenov [28]

Answer: The number of $12 tickets and $15 sold are 120 and 180 respectively.

Step-by-step explanation:

The given equation is:

12x + 15y = 4140             .....(1)

Where,

x stands for $12 tickets and y stands for $15 tickets

According to the question:

x + y = 300           ....(2)

Now solving equation 1 and 2.

From equation 2:

x = 300 - y

Now putting this expression in equation 1.

12x + 15y = 4140

12(300 - y) + 15y = 4140

3600 - 12y + 15y = 4140

3600 + 3y = 4140

3y = 4140 - 3600

3y = 540

y = 180

And,

x = 300 - y = 300 - 180 = 120

The number of $12 tickets sold = x = 120

The number of $15 tickets sold = y = 180

Thus, the number of $12 tickets and $15 sold are 120 and 180 respectively.
