A una obra de teatro acudieron 420 personas y se recaudaron $48,000.00. Si el costo de la entrada de los adultos fue de $200 y el costo de la entrada de niños costaba $80. ¿Cuántos adultos y niños que acudieron?

Answers

Answer 1

Answer:

La respuesta es que acudieron 120 adultos y 300 niños.

Step-by-step explanation:

De acuerdo a la información proporcionada, puedes escribir las siguientes ecuaciones:

x+y=420 (1)

200x+80y=48,000 (2), donde:

x es el número de adultos

y es el número de niños

Primero, puedes despejar x en (1):

x=420-y (3)

Ahora, puedes reemplazar (3) en (2):

200(420-y)+80y=48,000

84,000-200y+80y=48,000

84,000-48,000=200y-80y

36,000=120y

y=36,000/120

y=300

Finalmente, puedes reemplazar el valor de y en (3) para encontrar el valor de x:

x=420-y

x=420-300

x=120

De acuerdo a esto, la respuesta es que acudieron 120 adultos y 300 niños.

A candle has been burning for 20 min and is now 25 cm tall. In an hour it will be 10 cm tall. Which equation models the height y of the candle in centimeters, x minutes after it was lit?

Answers

Answer:

(y - 25) = - 0.25(x - 20)

Step-by-step explanation:

Given that :

Height of candle after burning for 20 minutes = 25 cm

Height after burning for 1 hr (60 minutes) = 10 cm

Height (y) in cm of candle x minutes after being lit:

Using the equation :

(y - y1) = m(x - x1)

m = (change in y / change in x)

Change in height within 60 minutes :

Height at 20 minutes = 25cm

Height after an hour = 10

Change in height per hour = (25 - 10) = 15cm

Hence, m = change in height per minute

15cm / 60 = 0.25cm ( - 0.25) (decrease in height)

y1 = 25 ; x1 = 20

(y - y1) = m(x - x1)

(y - 25) = - 0.25(x - 20)

10 times the product of g and h

Answers

Answer:

10(g*h)

Step-by-step explanation:

the * is supposed to mean times/multiply

since it is an expression you do not put y= or f(x)= or anything like that

Answer:

10(g*h)

Step-by-step explanation:

"Product" means multiply so you would want to multiply g and h together. You put it in parenthesis because you want to multiply the solution you get from multiplying g and h by 10. To show this, you can simply just put the 10 in front of  the parenthesis as that implies multiplication.

Complete question :

On average, light emitted from the Sun takes 8 minutes 19 seconds to reach Earth. Using your approximated speed of light from part (b), as well as the equation distance = rate x time, calculate the approximate distance from the Earth to the Sun in meters. Write your answer in standard form and in scientific notation.

Answer:

1.497 * 10^8km

149700000 km

Step-by-step explanation:

Given that:

Time taken = 8 minutes 19 seconds

Speed of light = 3 * 10^8 m/s

Distance from earth to sun :

Speed * time

(3 * 10^8) * ((8 * 60) + 19)

(3 * 10^8) * 499

= 1497 * 10^8 m or 1497 * 10^5 km = 1.497 * 10^8km

= 149700000000 m

= 149700000 km

= 1497

A park in the shape of a rectangle is 18 miles long and 24 miles wide. How much shorter is your walk
if you walk diagonally across the park instead of along the two sides of it?

Answers

Answer:

18² + 24² = x²

900 = x²

x = 30

18 + 24 = 42

42 - 30 = 12

Its shorter for 12 miles

Answer:

12 miles less

Step-by-step explanation:

18+24=42

If you walk in a L shape you walk 42 miles

If you walk diagonally:

ABC Right triangle

We have A and B (18 and 24)

Using the pythagorum theorem

a^2+b^2=c^2

18^2+24^2=C^2

324+576=C^2

900=C^2

Square root of 900=C

30=C

You would walk 30 miles

42-30=12

By walking diagonally, you would walk 12 miles less than going all the way around.

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

6x - 15 + 4x - 7 + 2x - 2 = 180, that is

12x - 24 = 180 ( add 24 to both sides )

12x = 204 ( divide both sides by 12 )

Type the correct answer in each box. Use numerals instead of words.

The value of each book is
.

The value of each music note is
.

Answers

Answer:

The value of each book is 7  

The value of each music note is 6

Step-by-step explanation:

The first equation includes the sum of 3 books and 2 music notes, so 3b + 2m = 33.

The second equation includes the sum of 1 book and 3 music notes, so b + 3m = 25.

This is the system that represents the puzzle:

3b + 2m = 33

b + 3m = 25  

Solve the second equation for b, and then substitute the equivalent expression for b in the first equation.  The value of each music note is 6.

Then, Substitute the value of m into one of the original equations to find the value of b . The value of each book is 7.

how do you graph x - y < 4

Answers

Answer: y > -4 + x

Step-by-step explanation: graph the inequality by finding the boundary line

Answer:

y > -4 + x

***(see graph below)****

Step-by-step explanation:

Graph

x − y < 4

Solve for y

Subtract x from both sides of the inequality.

−y < 4 − x

Multiply each term in −y < 4 − x by −1

Multiply each term in −y < 4 − x by −1. When multiplying or dividing both sides of an

  inequality by a negative value, f lip the direction of the inequality sign.

  (−y) ⋅ −1 > 4 ⋅ −1 + (−x) ⋅ −1

     Multiply (−y) ⋅ −1.

     Multiply −1 by −1.

     1y > 4 ⋅ −1 + (−x) ⋅ −1

     Multiply y by 1.

     y > 4 ⋅ −1 + (−x) ⋅ −1

Simplify each term.

     Multiply 4 by −1.

      y > −4 + (−x) ⋅ −1

     Multiply (−x) ⋅ −1.

y > −4 + x

   Find the slope and the y-intercept for the boundary line.

Rewrite in s lope-intercept form.

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

y = mx + b

Reorder −4 and x. y > x − 4

Use the slope-intercept form to find the slope and y-intercept.

Find the values of m and b using the form y = mx + b. m = 1

b = −4

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: 1

intercept: (0, −4)

Graph a dashed line, then shade the area above the boundary line since y is greater than −4 + x. y > −4 + x
