Answer:
28.65 yds (If you have to round do 29)
Step-by-step explanation:
a^2 + b^2 = c^2
14^2 + 25^2 = c^2
196 + 625 = 821
since c is squared you have to find the square root of 821
821 squared equals 28.65 yards

Is 2x+3y=24 proportional?
Answer:
no
Step-by-step explanation:
if you solved for 'y' you get y = -2/3x + 8 which means the y-intercept is 8 and in order for it to be proportional the y-intercept must be zero

Find the solution set of the following equations:
2y=2x+7
X=y+2
Answer:
The system of equations has no solution.
Step-by-step explanation:
Given the system of equations
2y = 2x+7
x = y+2
solving the system of equations
[tex]\begin{bmatrix}2y=2x+7\\ x=y+2\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}2y-2x=7\\ -y+x=2\end{bmatrix}[/tex]
Multiply -y+x=2 by 2: -2y+2x=4
[tex]\begin{bmatrix}2y-2x=7\\ -2y+2x=4\end{bmatrix}[/tex]
so adding
[tex]-2y+2x=4[/tex]
[tex]+[/tex]
[tex]\underline{2y-2x=7}[/tex]
[tex]0=11[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}2y-2x=7\\ 0=11\end{bmatrix}[/tex]
0 = 11 is false, therefore the system of equations has no solution.
Thus,
No Solution!

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

Ginny is making homemade pizzas for her family. The recipe makes 70 ounces of dough, but she made more that to ensure she had enough to feed everyone. She plans to freeze 28 ounces for next week, and the rest of the dough will be split evenly to make 3 pizzas. A. Write an inequality to represent the maximum weight of each pizza. Response area b. Each of Ginny's pizzas will weigh more than Response area ounces.
Answer:
14 ounce
Step-by-step explanation:
Given that:
Ounces of dough used in making recipe = 70 ounces
Number of ounces frozen = 28 ounces
Number of pizzas made from dough left = 3
Number of ounces left = total made - number frozen
Number of ounces left = 70 - 28 = 42
Weight of pizza made :
Number of ounces left / number of Pizzas made
42 / 3 = 14
Hence, maximum weight of each pizza made will weigh more than 14 ounces
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

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.
A factory makes 640brushes in 4 hours.Does the equation y=150x model the number of brushes made each hour?
Answer:
No it doesn't
Step-by-step explanation:
The equation we have is
Y = 150x
We have x = 4 hours
This is a simple question. We have to plug in the x = 4 in the equation to find out if we would have 640 brushes. If y = 640, then it models it. But if y is not equal to 640, it doesn't.
So let's solve this to see for ourselves.
Y = 150(x)
We put the value of x
Y = 150(4)
Y = 600
So we can see that the equation does not model the number of brushes made each hour. This equation models 600 brushes and not 640.
How many cups of lemonade please?
Cheddar cheese costs $3.45 per pound. Which equation best represents the total cost, c, of pounds, p, of cheddar cheese?
Answer:
c = 3.45 * p
Step-by-step explanation:
Since the total cost of Cheddar Cheese is dependant on the number of pounds that are being purchased then to calculate the total cost we would need to multiply the price per pound by the number of pounds being purchased. Therefore, the following equation would best represent the total cost of the cheddar cheese...
c = 3.45 * p
Evaluate the expression when c = 4, d = 1 and e = 10.
d+18

PLEASE HELP THIS IS TIMED!!!!!!!!!!!!!!!!!!!! A gumball machine had 78 gumballs. Each person who put a coin into the machine gets 3 gumballs. After a certain number of people got gumballs, there were 54 gumballs remaining. Estimate how many people got gumballs out of the machine.
Answer:
8 people got gumballs out of the machine.
Step-by-step explanation:
Given that:
Number of gumballs in machine = 78
Number of gumballs on each coin = 3
Number of gumballs left = 54
Let,
x be the number of people who put coin
Gumballs left = Total gumballs - 3*Number of people
54 = 78 - 3x
3x = 78 - 54
3x = 24
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{24}{3}\\x=8[/tex]
Hence,
8 people got gumballs out of the machine.
What is nearest $ 8.66 to nearest $
Answer:
$9 I think
Step-by-step explanation:
(hhhhhhhhaahahahahshshahahhaahaaaa
Answer:
$8.66 is rounded to $9
Step-by-step explanation:
When rounding a number, you round to the nearest whole number.
If the last digit is 5 or higher (5,6,7,8,9,) it rounds up
If the last digit is 4 or lower (1,2,3,4) it rounds down
Example:
$7.60 would be rounded to $8 because 6 is higher than 5, or in this case, 60 is higher than 50
$4.40 would be rounded to $4 because 4 is lower than 5, or in this case, 40 is lower than 50
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
