ivanzaharov [21]

Answer:

Step-by-step explanation:

Even though you didn't provide options from which to choose, you don't need them to figure out the system. We need an equation that involves the NUMBER of people and then we need an equation that involves the MONEY earned. Two different things here.

As for the number of people, we know that the number of adult tickets + the number of children = 12 people, so

x + y = 12.

That's the first equation. Now for the money:

21.50x + 14.75y = 204.00

That's your system.

You are designing a rectangular enclosure with 2 rectangular sections separated by parallel walls. The interior wall has a lengt

devlian [24]

Answer:

$P = 3L + 4W= 3*30 ft + 4*30 ft = 210 ft$

So then is required at least 210 ft in order to satisfy the conditions.

Step-by-step explanation:

For this case we can assume that the rectangular enclosure is on the figure attached.

The perimeter on this case is given by:

$P = 3L + 4W$

We know that the total area is $1800ft^2$ and the total area is given this formula:

$A= 2L W$

Because we have two identical rectangular pieces.

And we can find the value for W like this:

$W = \frac{A}{2L} =\frac{1800 ft^2}{2*30 ft}= 30ft$

And then we can find the perimeter like this:

$P = 3L + 4W= 3*30 ft + 4*30 ft = 210 ft$

So then is required at least 210 ft in order to satisfy the conditions.
