2.Ismael is comparing cell phone plans before upgrading his phone. Ameri-Mobile offers a low activation fee, but a high monthly payment. Cell-U-Later offers a lower monthly rate, but the activation fee is higher. Create a possible algebraic expression for both Ameri-Mobile and Cell-U-Later that shows the amount paid after an unknown amount of months have passed. Justify how you created those expressions, and identify what each term and factor represents in terms of the cell phone plans.

3.Ellen works for a high-speed rail company that wants to develop a new rail line. Ellen’s project is to find a train that is the second fastest in the world. The Shinkansen Bullet Train in Japan is reported to go as fast as 320 kilometers per hour. The TGV train in France can reach speeds of 89.44 meters per second. Explain to Ellen how to find what speed her new train must go to be the second fastest in this group. Then, find an appropriate speed for Ellen’s train in miles per hour and use the formula distance = speed • time to find how far the train can go in 2.5 hours. Use complete sentences and show your work.

4.Beatriz is creating graphs for her city’s Parks Department. Beatriz is trying to persuade the Parks Department to put in more gazebos for shade. For a local park, Beatriz wants to demonstrate the attendance as it changes every week. She also wants to show the temperature changes per month. Sometimes temperatures reach below zero. Explain to Beatriz how to make the graphs correctly based on the data that she will collect and what labels, scales, and intervals each axis must have on each graph. Use complete sentences and support your reasoning. Feel free to generate sample data to help support your response.

Answer 3

Two of your friends, Matt and Karen, both run to you to settle a dispute. They were working on a math problem, and got different answers. Wisely, you decide to look at their work to see if you can spot the source of confusion.

Matt

6 – 4(3 – 5)2 + 30 ÷ 5
6 – 4(–2)2 + 30 ÷ 5
6 – 4(4) + 30 ÷ 5
6 – 16 + 30 ÷ 5
−10 + 30 ÷ 5
20 ÷ 5
4
Karen

6 – 4(3 – 5)2 + 30 ÷ 5
6 – 4(–2)2 + 30 ÷ 5
6 – 4(−4) + 30 ÷ 5
6 + 16 + 30 ÷ 5
6 + 16 + 6
22 + 6
28
Explain to Matt and Karen who, if either, is correct, and identify errors that you find. Provide the correct manner to fix those solutions, and identify the correct answer. Use complete sentences.

Answer 4

and u didnt even call me :P

Answer 5

If Ameri-Mobile activation fee is $50.00 and $55.00 is the monthly payment and x will be the number of month after Ismael get the cell phone plan, the expression Is: 50 + 55x
If Cell-U-Later activation fee is $75.00 and $45.00 is the monthly payment and x will be the number of month after Ismael get the cell phone plan: the expression Is: 75 + 45x

Answer 6

#1? ^

Answer 8

my freking computer going crazy :P

Answer 9

it seems you need to start with defining a variable which counts the number of months of contract duration. Let's call this variable simply 'm'.

Then forget about the fact that you have two contracts but only look at the costs for a single contract. If you would sign up for such a contract and the company tells you to pay 10 USD now and after that 2 USD's per month, then you would pay the following for each additional month of your contract:

1st month (m=1) : 10+2 = 12
2nd month (m=2) : 10+2+2 = 14
3rd month (m=3) : 10+2+2+2 = 16
etc.

You probably can see the logic behind how to arrive at the overall costs. In this example I've jsut selected a startfee of 10 USD, but if there's no figure given, you can replace this number by 'S' and forget about an actual value. Same applies to the monthly fee, which you can replace by F if you don't know a value.

The overall formula for such a calculation then comes down to: C (for costs) = S + F*m.

Obviously, two different providers will require you to create two formulae of the same shape, but with specific/different values for S and F. Let me know if you don't understand this approach.

This is what I found for answers

Answer 10

This is what I found for number 3


First you have to convert all the speed in the same unit..
its entirely upto you to decide..
let us convert speed of SBT train in Japan to m/sec10 months ago




2now to convert it we multiply it's speed by 1000/3600 320∗10001∗3600 m/sec.. as 1 km =1000m and 1 hr = 3600 sec
