Maritza is comparing cell phones plans and notices that verizon offers a plan that is $60 for 10GB of data and $12 for each extr
lukranit [14]

Answer:

60 + 12 * g, with g representing the number of extra gigabytes

Step-by-step explanation:

First, we know that Maritza has to pay $60 for 10GB of data, no matter what. Therefore, the base cost of the cell phone plan is 60 dollars, and all extra costs must be added to that. Currently, our expression is therefore 60 + something = cost of cell phone plan.

After that, the plan costs $12 for each gigabyte of data past 10 GB. This means that, for example, if Maritza uses 11 gigabytes, the plan will cost 60 (the base amount) + 12 for each gigabyte past 10 GB. There are 11-10=1 extra gigabytes, so the cost is 60 + 12 * 1 = 72 dollars. For each extra gigabyte, 12 dollars are added, so we can represent this as

60 + 12 * g, with g representing the number of extra gigabytes

12. What is the probability that a point in the square below
andrew-mc [135]

Answer:

21.5\%

Step-by-step explanation:

we know that

The probability that a point in the square below  is in the shaded region, is equal to divide the area of the shaded region by the area of the square

step 1

Find the area of the shaded region

The area is equal to the area of the square minus the area of the circle

A=b^{2} -\pi(r)^{2}

we have

b=12\ cm ---> length side of the square

r=12/2=6\ cm ----> the radius is half the diameter

assume

\pi =3.14

substitute

A=12^{2} -(3.14)(6)^{2}

A=30.96\ cm^{2}

step 2

Find the area of the square

A=b^{2}

we have

b=12\ cm ---> length side of the square

substitute

A=12^{2}=144\ cm^{2}

step 3

Find the probability

P=30.96/144=0.215

Convert to percent form

0.215*100=21.5\%
