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

Step-by-step explanation:
Answer:
The one that says roller coaster in it.
Step-by-step explanation:
The rest are constant rates so they shouldn't be going up and down on a graph. Since the roller coaster height goes up and down and not straight, it would look like what is shown on the graph.

Answer:
1017.8
Step-by-step explanation:
this is the formula 4πr2
hope this helps: )
Answer:
Step-by-step explanation:
Volume of cone = π9²⋅12/3 = 324π cm³
volume of sphere = 4πr³/3 = 324π
r = ∛243
surface area of sphere = 4πr² ≈ 155.8π

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.

2. 72.8 cm
3. 28.35 Inches
4. I think its the 11, and the area is 49.14 inches
Area of rectangle = base × height
Area of parallelogram = base × height
1.
[tex]\displaystyle 2.25 \times 1.5=3.375 \ or \ 3\frac{3}{8} \ ft^2[/tex]
2.

The measurement that is unnecessary is 11.7 inches because only base and height is required to find the area.
-5(4x-6) help pls I am dead so I can't solve it.
Answer:
-20x+30
Step-by-step explanation:
Using distributive property take -5 and multiply 4x and -6 to that -5
That equals 4 x 5 is 20
add the negative -20
add the x -20x
-5 x -6 = 30
add the final product together
-20x+30
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

Answer:
A: 4.4 B: 0.875
Step-by-step explanation:
22/5=4.4. We know this because 22/5 simplified is 4 2/5, which converted to a decimal is 4.4.
7/8=0.875. We know this because 7/8 converted to a decimal is 0.875.
En una zona industrial se encuentran dos contenedores: en uno hay 198 litros de jugo de arándanos y en el otro hay 144 litros . Para su transporte se requiere guardar el jugo en el menor número de envases iguales. ¿Cuál debe ser la capacidad máxima de estos envases para que no sobre jugo?
Answer:
2 envases iguales de 171 litros
Step-by-step explanation:
Para calcular esto, primero necesitamos sumar los dos contenedores y cuantos litros de jugo tienen cada uno.
198 + 144 = 342 litros.
Ahora tenemos que calcular el numero minimo de envases. Si ya sabemos que es un numero par entonces lo podemos dividir en dos envases iguales sin que sobre...
342 / 2 = 171 litros
Finalmente, podemos ver que podemos dividir el jugo en 2 envases iguales de 171 litros

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 table below shows X and Y values for the equation Y = X + 13
What is Y when X = 17?
Answer:

Step-by-step explanation:
[tex]Y=X+13[/tex]
If X = 17, you have to add that with 13 to get Y.
[tex]17(X)+13=30\\Y=30[/tex]

so, y=102
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.
