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
for numbers 19 and 20 you have to solve for the missing angle.
Answer:19. 17 degrees
20. 49 degrees
Step-by-step explanation:
Because of the postulate 50+?=67
So ?=17
And 20.
94+?=143
So
?=49
(Edit)I though you only meant 19 and 20

Work out the question (-5)2
Answer:
-10 or 25 (read my explanation)
Step-by-step explanation:
(-5)2
-5*2=-10
(Unless the 2 is supposed to be an exponent)
If it is supposed to be an exponent the answer is 25
(-5)^2
25
[tex]\huge\boxed{Hi\;there!}[/tex]
(-5)2 means negative five times 2.
The answer is -10.
Remember, if we multiply a negative times a positive, we get a negative number.

Edna buys a bottle of dog shampoo that costs 3.99$. The bottle contains 28.5 ounces of shampoo. What is the cost per ounce of shampoo?
Answer: $0.14 per ounce
Step-by-step explanation:
There are 28.5 ounces of shampoo in the shampoo bottle and the cost of the whole bottle is $3.99.
The cost per ounces will therefore be:
= Cost of bottle / Number of ounces
= 3.99 / 28.5
= $0.14 per ounce
Jaden scores 100 points in the first round of a game. He earned 20 points in each of the following rounds of the game. He ended the game with 400 points. Write and solve an equation that could be used to determine the number of extra rounds Jaden played.
Answer:
100 + 20 x n = 400
Step-by-step explanation:
If he ended the game with 400 points, and he scored 100 points in the first round, and 20 points every round after that, then we have to find out how many rounds he played using multiplication and addition. n represents the number of rounds he played, which is what we want to find out. What number do you have to multiply 20 by to get 300? the answer is 10. Therefore, n is 10.

For camping mrjohn son needs 12 1-2 feet of rope to tie the logs that he has to cut for the campfire and 9 3-4 feet of the rope for the clothesline what is the total length of rope he needs for the camping trip
Answer:
Mr. John will need not less than [tex]22\frac{1}{4}[/tex] feet of rope for the camping trip
Step-by-step explanation:
To get the total length of rope Mr John needs for the camping trip, we can simply add up the length of rope he needs to tie the logs to the length of rope he needs for the clothesline.
Length of rope he needs to tie the logs = [tex]12\frac{1}{2}[/tex]
Length of rope he needs for the clothesline = [tex]9 \frac{3}{4}[/tex]
to sum this up, we, first of all, add up the whole numbers
12 + 9 = 21.
We then keep this aside then add up the fractions
[tex]\frac{1}{2} +\frac{3}{4} =\frac{2 +3}{4} = 5/4 = 1\frac{1}{4}[/tex]
We then add this to our whole numbers
[tex]21 + 1\frac{1}{4} =22 \frac{1}{4}[/tex]
Mr. John will need not less than [tex]22\frac{1}{4}[/tex] feet of rope for the camping trip

A rectangular garden has a length that is 3 feet longer than its width. Let w represent the width of the garden in feet. The entire garden is surrounded by a 2-foot-wide cement walkway.
Answer:
Step-by-step explanation:
From the question, we're told that the length of the garden is 3 feet longer than its width. Mathematically, we would have
l = w + 3, where
l = length of the garden
w = width of the garden
Again we're told that this same garden has a walkway of about 2 foot wide. Mathematically we would have that as
W(w) = 2, where
W(w) = width of the garden.
That's all the parameters given in the question
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.

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

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.

9514 1404 393
Answer:
2/3·fg
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)
(ab)^c = (a^c)(b^c)
(a^b)^c) = a^(bc)
__
We assume your 'x' is a multiplication symbol, so you want to simplify ...
[tex]3f^4g^3 \times\dfrac{ 8fg^4}{ (6f^2g^3)^2}\\\\=\dfrac{3\cdot8f^{4+1}g^{3+4}}{6^2f^{2\cdot2}g^{3\cdot2}}=\dfrac{24}{36}f^{5-4}g^{7-6}\\\\=\boxed{\dfrac{2}{3}fg}[/tex]
