Step-by-step explanation:

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

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

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.

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

#look pic for detailed info

180° - 125° = 55°

180° - 115° = 65°

180° - 55° - 65° = 60°

180° - 60° = 120°

180° - 120° = 60°

Answer:

x = 120°

Step-by-step explanation:

you can draw a perpendicular base betweeen the two parallel segments and form a pentagon, which has 540 degrees inside.

the two base angles will each be 90°, and we have known values for the other two.

as far as 'x', that angle is vertical to the top angle of the pentagon so we add up all the known values and solve for 'x':

90 + 90 + 125 + 115 + x = 540

180 + 240 + x = 540

x = 540 - (180 + 240)

x = 540 - 420

x = 120

Answer:

X=3/3=1

Hope it helps.

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!!

Answer:

z=70, y=102

Step-by-step explanation:

180-110 = 70

so, z=70

99+89+70 = 258

360-258 = 102

so, y=102

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.

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:

-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.

Step-by-step explanation:

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).

Answer: 5h+4=A

Step-by-step explanation:

She gets five dollars an hour so for one hour she gets five dollars, for two hours she gets 2 times 5 dollars (10 dollars), for three hours she gets 3 times 5 dollars (15 dollars) etc...

Now replace the 1,2,3... with the variable representing the hour. In this case it would be h. So 5h=five dollars per hour. Because you only put the kid to bed once, you add four at the end
