X : number of tacos they sell per day. ...... profit = y = 3.25 × x - 210 ......inequality. y > 0. so. x > 210/3.25 = 840/13 = 64. ......so the taco stand must sell at least 65 tacos for making profit.
Based on the way these stations are connected, we can infer that there are <u>56 tubes. </u>
<h3>Number of tubes in Spaceland </h3>
Each pair of stations have 2 tubes. This means that every station is connected to each of the others.
We can therefore infer that each station has 7 tubes to the other stations.
The total number of tubes would therefore be:
= Number of stations x Number of tubes per station
= 8 x 7
= 56 tubes
In conclusion, there are 56 tubes.

First, calculate f(g(x))==> you plug (5x+4) in the value of x in f(x)
==>f(g(x))= 8-[10(5x+4)===>8-50x-40===>f(g(x))= -50x + 32
& f(g(-2))= -100+32 =68.
There is a mistake in your answers, it should be 68 & not 78
Let us assume the width of the rectangle = x
Then
The length of the rectangle = 2x
The perimeter of the rectangle = 24 inches
We know the formula of the perimeter of a rectangle is
Perimeter = 2 (length + Breadth)
24 = 2 (2x + x)
24 = 2 * 3x
24 = 6x
x = 24/6
= 4
So the width of the rectangle = 4 inches
length of the rectangle = 2x
= 2 * 4 inches
= 8 inches
Now
The Area of the rectangle = Width * Length
= 4 * 8 inches^2
= 32 inches ^2
So the area of the rectangle is 32 square inches. I hope i have helped you.
