The City Zoo has different admission prices for children and adults. When three adults and two children went to the zoo, the pri

ce was $81.22. If two adults and three children got in for $77.18, then what is the price of an adult's ticket and what is the price of a child's ticket?

Let the price of a children's ticket be x and the price of an adult's ticket be y. We can form a system of equations to solve this problem.


2x + 3y = 81.22

3x + 2y = 77.18


Lets use elimination to solve the system. First, lets multiply the first equation by 3 and the second equation by 2 so the x terms will cancel out.


6x + 9y = 243.66

6x + 4y = 154.36


We can then subtract the equations to cancel out the x variable.


6x + 9y = 243.66

-(6x + 4y = 154.36)

(6x-6x) + (9y - 4y) = (243.66 - 154.36)

0 + 5y = 89.30


Finally, we can find the value of y.


5y = 89.30

y = 17.86


Lastly, we can plug in the value of y and solve for x to find the value of the child's ticket.


2x + 3(17.86) = 81.22

2x + 53.58 = 81.22

2x = 27.64

x = 13.82


Therefore, the child ticket costs $13.82 and the adult ticket costs $17.86.

tatyana61 [14]

Answer:

A = 40.0 (3 sig. fig)

C = 40

c = 15

Step-by-step explanation:

Using sin law,

sinA/15 = sin100/23

A = 40.0 (3 sig. fig)

Using angle sum of triange,

C = 180 - 40.0 - 100 = 40

Since angleA = angleC, by side equal opp angles, c = 15

The inside of a beaker is shaped like a circular cylinder with a base diameter of 121212 centimeters (\text{cm})(cm)(, start tex
Radda [10]

Answer:

9 cm

Step-by-step explanation:

Since the container is a cylinder of base diameter d₁ = 12 cm and thus radius r = 12/2 = 6 cm. The water height is 8 cm. The initial volume of water is thus V₁ = πr²h = π × 6² × 8 = 288π cm³.

The sphere of diameter d = 6 cm has radius r₁ = 6/2 = 3 cm. Its volume V₂ = 4πr³/3 = 4π × 3³/3 = 36π cm³

Since the sphere displaces it own volume of liquid, the new volume V = V₁ + V₂ = 288π cm³ + 36π cm³ = 324π cm³

This is the new volume of water in the cylinder. Since the water level rises by h' cm and V = πr²h'

h' = V/πr²

= 324π cm³/π(6)²

= 324π cm³/36π cm²

= 9 cm

So, the water level is 9 cm above the base

I suck at story problems can I please have help?
Mamont248 [21]

a.

b=cost per burrioto

t=cost per taco


b.

3 burritos and 4 tacos costs 11.33; 3b+4t=11.33

9 burritos and 4 tacos costs 22.07; 9b+4t=22.07


c. solve

3b+4t=11.33

9b+4t=22.07

mulitply irst equation by -1 and add to 2nd to cancel t's


-3b-4t=-11.33

<u>9b+4t=22.07 +</u>

6b+0t=10.74


6b=10.74

divide both sides by 6

b=1.79

subsitute back


3b+4t=11.33

3(1.79)+4t=11.33

5.37+4t=11.33

4t=5.96

divide both sides by 4

t=1.49


solution: 1 taco costs $1.49 and 1 burrito costs $1.79

Solve this proportion for x<br> x/4=30/6
Harlamova29_29 [7]

Answer:

20

Step-by-step explanation:

You need to isolate your variable by multiplying by four to cancel out the four in the denominator. When you do this, on the other side you get 120/6, or 20.
