I need help with this please.I don’t understand it.
1. Estimate how many minutes you talk on your cell phone every month________(you can randomly pick) 2. Which plan above do you think will result in the cheapest plan for you? Why do you think so?
Problem 1
This answer will vary from person to person. And as your teacher says, you can also randomly pick a value if you aren't sure.
Let's say you spend an hour each day talking on your phone. This means voice calls and not texting. Video calling could also be part of voice calling, though it will depend on how your cell phone company structures the cell phone plan.
Anyways, let's go with 1 hour. This converts to 60 minutes.
If you talk for 60 minutes per day, then you spend 60*30 = 1800 minutes per month talking on the phone. This is an average value. I'm using 30 days per month.
Answer: 1800 minutes
=====================================================
Problem 2
For each of the 6 companies, form their respective equations
x = number of minutes
y = total cost per month
We get the following equations for each company:
Rogers (all day plan): y = 0.25xFido: y = 0.20xTelus: y = 0.35xRogers (MY5 Prepaid): y = 0.25x+20Bell: y = 0.10x+10Public Mobile: y = 0x+24 which simplifies to y = 24With those 6 plans in mind, we will plug x = 1800 into each equation
Doing so leads to...
Rogers (all day plan): y = 0.25x = 0.25*1800 = 450Fido: y = 0.20x = 0.20*1800 = 360Telus: y = 0.35x = 0.35*1800 = 630Rogers (MY5 Prepaid): y = 0.25x+20 = 0.25*1800+20 = 470Bell: y = 0.10x+10 = 0.10*1800+10 = 190Public Mobile: The monthly cost is $24 a month regardless of how many minutes you use. This is an unlimited minutes plan.So we can see that clearly Public Mobile has the lowest cost per month at $24 a month. The cost per minute of $0 means that we have unlimited minutes here. The other costs are really high and far from $24. The next smallest value is $190, which is far from $24.
Is Public Mobile always the best choice? It depends. Refer to the chart below (attached image) and you'll see that the yellow cells are instances when Public Mobile isn't the cheapest option. However, note how small x has to be for this to occur and note how the yellow cells don't show up very often. Sure we could make more yellow cells pop up if we used even smaller x values, but at a certain point, it's likely not to be realistic. Why have a cell phone plan if you don't use the minutes to talk on it? Of course, everyone is different.
Anyway, for the x value chosen in problem 1, the Public Mobile plan is the cheapest option at $24 per month.
Answer: Public Mobile

Step-by-step explanation:
25 divided by 5 = 5
45 divided by 5= 9
so 25/45 = 5/9
5x3=15
9x3=27
so 5/9=15/27

Answer:
x=14
Step-by-step explanation:
1 way
Step 1: Subtract 3/4x from both sides.
1/4x − 5 − 3/4x=3/4x−12−3/4x
−1/2x−5=−12
Step 2: Add 5 to both sides.
−1/2x−5+5=−12+5
−1/2x=−7
Step 3: Multiply both sides by 2/(-1).
(2/−1)*(−1/2x)=(2/−1)*(−7)
2nd way
Add 5 to both sides
1/4x - 5+5 = 3/4x - 12+5
Simplify
1/4x = 3/4x -7
Subtract 3/4x from both sides
1/4x-3/4x= 3/4x-7-3/4x
Simplify
-1/2x=-7
Multiply both sides by -2
(-1/2x)(-2)=(-7)(-2)
x=14

Tom promised that for every 4 hours that he played video games, he would solve 16 math problems. Going by his promise, which of the following statements is correct?
A.
He would solve 32 math problems if he played video games for 9 hours.
B.
He would solve 30 math problems if he played video games for 8 hours.
C.
He would solve 32 math problems if he played video games for 8 hours.
D.
He would solve 48 math problems if he played video games for 9 hours.
Answer:
A
Step-by-step explanation:
because of the gravity of thw earth
Answer:
C. He would solve 32 math problems if he played video games for 8 hours.
Step-by-step explanation:
Create the following proportion to find the number of math problems for 8 hours:
4/16 = 8/x
Cross multiply.
4 x x = 4x
16 x 8 = 128
4x = 128
x = 32
If Tom plays video games for 8 hours, he'll solve 32 math problems.
Create the following proportion to find the number of math problems in 9 hours:
4/16 = 9/x
Cross multiply.
4 x x = 4x
16 x 9 = 144
4x = 144
x = 36
If Tom plays video games for 9 hours, he'll solve 36 math problems.

Answer:
3 inches
Step-by-step explanation:
If we're gonna have some sort of increase each year, it's gonna pop up in our model attached to a variable, because it represents some kind of change, and variables can change. Looking at our equation, the 28.6 represents our starting point: the boy is 28.6 inches tall when he's 2 years old. The 3a term, then, represents the boy's increasing height each year. When he's 3 years old, a = 1, and so h = 3 + 28.6 = 31.6 inches. When he's 4, a = 2, and h = 3 + 31.6 = 34.6. The increase is always 3 inches.

One of the tokens for a board game is a circle with a radius of 15 millimeters. Which measurement is closest to the circumference of the token in millimeters?
Answer:
The circumference of the circle is approximately 92 mm
Step-by-step explanation:
For us to be given the radius of the tokens it is safe for us to make the assumption that the token is circular in shape. Thus, we can solve the problem using various theories in circle geometry.
We will use the circumference equation to estimate the circumference of the circle, assuming the value of π is = 3.14
The circumference of a circle can be given as 2 X π X radius
This will be 2 X 3.142 X 15 = 94.247 ≈92mm
Therefore, the circumference of the circle is approximately 92 mm

Find the volume of a rectangular prism that has a height of 5 meters and the area of the base is 8cm squared
Answer:
Volume of prism = 4000 cm cubed
Step-by-step explanation:
Given that:
Height of rectangular prism = 5 meters
Converting into centimeters as the area of base is in centimeters.
1 meter = 100 centimeter
5 meters = 500 cm
Area of the base = 8 cm squared
Volume of prism = Area of base * Height
Volume of prism = 8 * 500
Volume of prism = 4000 cm cubed
Hence,
Volume of prism = 4000 cm cubed
