Answer: The length of the rectangle is 13.5 units and the width is 4.5 units

Step-by-step explanation: The perimeter of the rectangle has been given as 36 units. The formula applied to calculate the perimeter is

Perimeter = 2(L + W)

However the details in the question states that the rectangle is three times as long as it is wide. That is, the length is three times it’s width. So if the width is W then the length is 3W.

Therefore, to calculate the perimeter we shall apply the following;

Perimeter = 2(3W + W)

If the perimeter is given as 36 units, then we have;

36 = 2(4W)

We cross multiply and we have

36/2 = 4W

18 = 4W

Divide both sides of the equation by 4

4.5 = W

So the width is calculated as 4.5, hence the length would be 3W which equals 3 x 4.5 and that equals 13.5

Therefore, Length = 13.5 units and Width = 4.5 units

Dash offers and unlimited talk and texting plan for $80 per month AB&C charges $0.20 per text message and $55 for 1,000 min
mr_godi [17]

Answer:

Let's define x as the number of text messages send.

y as the number of 1,000 minutes talk per month.

(so we can write y = N/1000) where N is exactly the number of minutes that you talked that month.

> The equation for Dash is:

C1(x, y) = $80

>The equation for AB&C

C2(x,y) = $0,20*x + $55*y

> Horizon

C3(x,y) = $0.10*x + $75*y.

Now, which company you should go for?

Well, it depends on the values of x and y that you have.

if in your case you have x > y, you may want to go with Horizon, because the price per text is smaller.

if you usually talk, you may want to go with AB&C because the slope for y is smaller.

If you send a lot of texts and talk a lot, then Dash is the best option, because there is no dependence with the variables x, y

= π(5)2
=25 π

Area of the bigger circle inside
= π x(3)2
= 9 π
Area of the smaller circle inside
= π x (2)2
= 4 π

Area of shaded region
= 25π - 9π - 4π
= 12π square unit
