1 of 9 3 7 of students at a school are boys. If there are 2282 students at the school, how many are girls?

Answer:

3

Step-by-step explanation:

3 ÷ 3 = 1

21x ÷ 3 = 7x

There is no other common factor.

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

Step-by-step explanation:

y = mx + b

y = -5x - 1......slope here is -5 and y int is -1

y = -5x + 7....slope here is -5 and y int is 7

#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:

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:

-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

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.

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.

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:

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

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:

1026

Step-by-step explanation:

as everyone knows that up to 4 the number increases so here it is 4 so it decreases we can't increase it .

hope it helps.

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
