Tracy has a cell phone plan that provides 250 free minutes each month for a flat rate of $29.

natali 33 [55]

Answer:

250 minutes with the flat rate of $29.

$x\leq 250$

x would be the number of minutes called.

$x-250$

Tracy would be charged by $0.35 per minute.

$f(x)=29\\ 0\leq x\leq 250$

$f(x)=0.35(x-250)+29,\\250\leq x\leq ∞$

Answer:

528 cm²

Step-by-step explanation:

First I would calculate the area of the side rectangles:

20 x 9 = 180 cm²

There are two identical rectangles on both sides so i would x2

180 x 2 = 360 cm²

The area of the middle rectangle:

6 x 20 = 120 cm²

The area of the triangles:

Area of a triangle = (Base x Height)/2

8 x 6 = 48

48 ÷ 2 = 24

There are two identical triangles on the bottom and the top so x2

24 x 2 = 48

Now add all the values up:

360 + 120 + 48 = 528 cm²

I hope this helps!
