\bf \textit{surface area of a cylinder}\\\\ SA=2\pi r(h+r)~~ \begin{cases} \textit{units all tripled}\\ h=3h\\ r=3r \end{cases}\implies SA=2\pi (3r)(3h+3r) \\\\\\ \begin{cases} r=\stackrel{mm}{4}\\ h=\stackrel{cm}{1.5}\\ ~~~~\stackrel{mm}{15} \end{cases}\implies SA=2\pi (12)(45+12)\implies SA=24\pi (57) \\\\\\ SA=1368\pi


now, recall, the exercise is assuming you're using π = 3.14.

Tallulah has a dimes and y nickels. She has at most 18 coins worth at
nexus9112 [7]

One possible solution for the system of inequalities is given as follows:

13 dimes and 2 nickels.

<h3>How to obtain the system of inequalities?</h3>

The first step in obtaining the system of inequalities is identifying the variables, which are given as follows:

  • Variable x: number of dimes that Tallulah has.
  • Variable y: number of nickels that Tallulah has.

Tallulah has at most 18 coins, hence:

x + y ≤ 18.

A nickel is worth 5 cents = $0.05, while a dime is worth 10 cents = $0.1, and Tallulah has at least $1.20 combined, hence:

0.1x + 0.05y ≥ 1.20.

The solution is given by the shaded region on the image given at the end of the answer, and one possible solution is given as follows:

x = 13, y = 2.

Which means that she has 13 dimes and 2 nickels.

Tickets for a tour of a city cost $5. A tour will only happen when a total of at least 20 tickets and no more than 45 tickets ha
professor190 [17]

Answer:

y(x)=5x for (20≥x≤40)

Step-by-step explanation:

Step one :

Given data

Cost of ticket =$5

Given that the number of tickets to be sold for the tour to happen should be at least 20 and not more than 40

Step two :

Let the number of tickets be x

And let the revenue or income be y

The function for the cost is expressed linearly as

y(x)=5x

The domain is y(x)=5x for (20≥x≤40)
