A study showed that the ratio of the number of people who get their news from print sources to the number of people who get their news from social media sources is 3:7. Based on the ratio, how many people in a town of 900 people get their news from social media sources?
Two classmates solved this problem and their work is shown below. Which classmate solved the problem correctly? Explain the error in the classmate who solved it incorrectly.
Answer:
270 = number who get news from print sources
630 = number who get news from social media
Step-by-step explanation:
Let 3x = number who get news from print sources
and 7x = number who get news from social media
Then 3x + 7x = 900
10x = 900
x = 90
3x = 3(90) = 270 = number who get news from print sources
7x = 7(90) = 630 = number who get news from social media
Check: 270/630 = 3/7 and 270 + 630 = 900

Find the missing value to the nearest hundredth sin= 7/25
Answer:
16.26
Step-by-step explanation:
I am not completely sure what the problem is asking, but I believe that you are just supposed to take the inverse of sine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then sine. You use the inverse of sine when two sides are given, but you are not given the angle.
It should look like:
[tex]sin^{-1}(\frac{7}{25})[/tex], which is approximately 16.26.
Hopefully this is right, if not, please let me know. Good luck.
A family wants to rent a car to go on vacation. Company A charges $45.50 and 11c per mile. Company B charges $60.50 and 13c per mile. How much does Company B charge for x miles than company A?
Answer: Company B charges $(15.5+0.12x) more for x miles than company A.
Step-by-step explanation:
Let x = Number of miles.
Total charge = Flat charge + (charge per mile) x (Number of miles)
Given:
For Company A ,
Flat charge= $45
Charge per mile = 11 cents = 0.11 [ 1 dollar = 100 cents i.e. 1 cent = 0.01 dollar]
Total charge = 45+0.01x
For Company B,
Flat charge= $60.50
Charge per mile = 13 cents = 0.13
Total charge = 60.50+0.13x
Difference in charge = Charge for company B - Charge for company A
= 60.50+0.13x-(45+0.01x)
= 15.5+0.12x
Hence, Company B charges $(15.5+0.12x) more for x miles than company A.

A student collects post cards from around the world. She has 150 post cards. Of these post cards, 42% are from Africa, 20% are from Europe, 10% are
from Asia, and the rest are from South America. How many post cards are from South America?
Answer:
42 post cards
Step-by-step explanation:
First, let's find how many cards are from each country by multiplying the decimal forms of the percent by the total number of post cards (150).
Reminder: to get the decimal form of a percent you move the decimal point twice to the left!
Africa: (.42)(150) = 63
Europe: (.20)(150) = 30
Asia: (.10)(150) = 15
Add all of them
63 + 30 + 15
= 108
Subtract it from the total
150 - 108
= 42
Another way to do this is to add up the percent's and then subtract it from 100, convert that to decimal form and multiply it by 150. Like this:
42% + 20% + 10% = 72%
100 - 72 = 28
(.28)(150) = 42
Therefore, 42 post cards are from South America.
I hope this helps!!

As a good customer, Verizon offers you 17% off your next bill. If your bill is normally $75, how much will Verizon's discount save you?
Answer:
The discount saves you $12.75.
Step-by-step explanation:
If your bill is 17% off, you only play 83% of it.
75*0.83 = 62.25
Then subtract from your original bill.
75-62.25= 12.75
The discount saves you $12.75.
The value of the decrement can be found by finding the decrement percentage of the quantity. The amount that can be saved after discount is $12.75.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
To convert percentage into a fraction it is divided by 100.
Given that,
The offer on the bill = 17%
The value of the bill = $75
The amount saved by the discount is the offer percentage of the bill amount. It can be written as,
17% of 75
= (17 / 100) × 75
= 12.75
Hence, Verizon's discount will save $12.75.

Is (-5,17) a solution of y=3x+2?
Answer:
no
Step-by-step explanation:
When solving this equation you would substitute the x coordinate for x and the y coordinate for y:
[tex]17=(3*-5)+2[/tex]
Then multiply -5 and 3:
[tex]17=-15+2[/tex]
Then, add it out and you will come to the conclusion that it equals negative 13 not 17. The correct answer would be (5,17).

Step-by-step explanation:
Each hoodie costs the trader $20 and he intends to sell it at a Percentage markup of 65%
a) Write a percentage Markup value as a
I) Fraction
Percentage Markup = 65%
65% = 65/100 = 13/20
II) Decimal
= 65% = 65/100 = 0.65
b) Calculate the value of Markup of each hoodie
This is calculated as:
65% × Cost price
= 65% × $20
0.65 × $20 = $13
c) What price would the hoodies be?
Cost price of hoodie = $20
Percentage Markup = 65%
The selling price = x
Percentage Markup = Selling price - Cost price/Cost price
65% = x - $20/$20
Cross Multiply
0.65 × $20 = x - $20
13 = x - $20
x = $20 + 13
x = $33
Therefore, the selling price = $33
d) If the seller sells 35 hoodies on her first day, what is her profit.
Profit = Selling price - Cost price
Profit = $33 × 35 hoodies - $20 × 35 hoodies
Profit = $1155 - $700
Profit = $455
We are told that to improve sales, the seller gives a discount of 10% on selling price
Hence:
Selling price = $33
e) What is the discount amount for each hoodie
Discount Amount = % Discount × Selling price
Discount Amount = 10% × $33
= $3.3
f) What is the new selling price =
Old selling price - Discount amount
= $33 - $3.3
= $29.7
g) What profit does the seller make on each hoodie after the 10% discount for 35 hoodies
Profit = Selling price - Cost price
Profit = $29.7 × 35 hoodies - $20 × 35 hoodies
Profit = $1039.5 − $700
= $339.5
Jesse has 158 quarters and nickels. The value of the collection is $19.10. How many of each coin does she have?
Answer:
102 nickels and 56 quarters
Step-by-step explanation:
Since the total amount of coins is 158, then...
q+n=158
Since the total amount of money is $19.10, and a quarter is 25 cents and a nickel is 5 cents, then...
0.25q+0.05n=19.10
Now that we have 2 equations and 2 variables, we can solve for this equation by solving the first equation for q and plugging it into the second equation.
q+n=158,
q=158-n
Plug into the other equation,
0.25(158-n)+0.05n=19.10
and solve for n
39.5-0.25n+0.05n=19.10
39.5-0.2n=19.10
-0.2n=-20.4
n=102
there are 102 nickels.
Now solve for quarters.
q+n=158
q+102=158
q=158-102
q=56
The volume of a cube is a function of the side length. Similarly the surface area of a cube is a function of its side length which of these relationships is linear function construct an argument to justify your response
Answer:
None is
Step-by-step explanation:
Given
Volume and Surface area of a cube
Required
Which is linear
The volume of a cube is:
[tex]V(x) = x^3[/tex]
While the surface are is:
[tex]A(x) = 6x^2[/tex]
Where x represents the length of the side
A linear function construct is represented as:
[tex]f(x) = mx + c[/tex]
By comparing A(x) and V(x) to f(x):
f(x) do not have any form of exponent while A(x) and V(x) have.
So, we can see that both functions are not linear

what is the degree of
f (x) = -5x
it is a linear function?
What is the m and b?
Answer:
The degree is 1
It is a linear function
m = -5 and b = 0
Step-by-step explanation:
Here, we want to get the degree of the equation
As we can see, it is a linear function with the highest power of as 1
That means it is of degree 1
Comparing with the general form;
y = mx + b
m = -5
b = 0
