$9 for adults and $6 for children. If the movie theater cashier collects $1719 from the sale of 200 tickets, how many adult tick

Bad White [126]

Hey there!!

We will have to solve this using 2 variables

Let's take the number of adults as ' x '

Let's the number of children as ' y '

The total number of tickets = 200

Let me explain this : If the total number of tickets is equal to 200, then the total number of people is equal to 200

Hence , x + y = 200

$9 for adults

The total cost for adult tickets = 9x

$6 for children

The total cost for children tickets = 6y

The total cost for these tickets = $1719

9x + 6y = 1719

3 ( 3x + 2y ) = 1719

3x + 2y = 573

...................................................................................................................................................

Now we have two equations

x + y = 200 ------------- ( 1 )

3x + 2y = 573 ---------- ( 2 )

Now let's multiply the first equation with 2

2 ( x + y ) = 2 ( 200 ) -------- ( 1 )

3x + 2y = 573

.......................

2x + 2y = 400

3x + 2y = 573

Now let's subtract the first equation from second

- ( 2x + 2y ) = - ( 400 )

3x + 2y = 573

..............................

-2x - 2y = - 400

3x + 2y = 573

x = 173

Hence , the number of adult tickets sold = 173

The required answer = 173

Hope my answer helps!

Out of the 160 boys and girls playing soccer tournament, 32 of them are wearing orange. What percent of players are wearing oran

vfiekz [6]

Answer:

The percent of players are wearing orange is 20%.

Step-by-step explanation:

Total number of players is 160.

Total number of players who wearing orange is 32.

$\text{Percent of players are wearing orange}=\frac{\text{Total players are wearing orange}}{\text{Total number of players}}\times 100$

$\text{Percent of players are wearing orange}=\frac{32}{160}\times 100$

$\text{Percent of players are wearing orange}=20$

Therefore, the percent of players are wearing orange is 20%.

<span>C is the correct answer.
If you want to check it just divide both sides by six.
</span>3/6x + 2/6y = 18/6

Let (6,-5) be a point on the terminal side of θ. Find the exact values of sin θ, sec θ, and tan θ.

makvit [3.9K]

Answer:

sinθ = -5/√61

secθ = √61/6

tanθ = -5/6

Step-by-step explanation:

From the given coordinate (6, -5), x = 6 and y = -5. This shows that the point lies in the 4th quadrant. In the fourth quadrant, only cos θ is positive, both sin θ and tan θ are negative.

Let us get the value of the radius 'r' first before calculating the trigonometry identities.

Using the Pythagoras theorem;

$r^2 = x^2 + y^2\\r^2 = 6^2 + (-5)^2\\r^2 = 36+25\\r^2 = 61\\r = \sqrt{61}$

Using SOH, CAH, TOA to get the trigonometry identities;

Given x = 6, y =5 and r = √61

$sin \theta = opp/hyp = y/r\\sin \theta = 5/\sqrt{61} \\$

Since sin θ, is negative in the fourth quadrant, $sin \theta = -5/\sqrt{61} \\$

$cos \theta = adj/hyp = x/r\\cos \theta = 6/\sqrt{61} \\$

$sec \theta = \frac{1}{cos \theta} \\sec \theta = \frac{1}{6/\sqrt{61} } \\sec \theta = \frac{\sqrt{61} }{6}$

For tanθ:

$tan \theta = \frac{opp}{adj} = \frac{y}{x} \\tan \theta = \frac{5}{6}\\$

Since tan θ, is negative in the fourth quadrant, $tan \theta = -5/6$
