Answer:

87 Adult tickets were sold

Step-by-step explanation:

This type of question relates to a system of equations. These types of questions are pretty easy to spot and they are just about solved all the same way.

So what we first want to do is see that there is a total of 159 tickets sold. Now obviously that number consists of the adult and children tickets, therefore we need to add those two unknown numbers to get 159, so x will be for adults and y will be for children tickets. this will give us the equation x + y= 159.

Next, we want to associate the amount those tickets are with those variables, because you can only have so many adult tickets and children tickets with the given $1794. So what we need to do is similar, we just have those totals added to get the equation 14x + 8y = 1794.

Now we want to use the process of elimination to find the value of x (because we are solving how many adult tickets were sold). IN order to do elimination, we need to have the equation x + y= 159 cancel the y value to leave us with the x value. In order to do this, you need to multiply y by a value that cancels 8y in 14x + 8y = 1794, which is -8.

So we multiply the entire equation of x + y= 159 by -8 to get. Now we would add these equations together where you subtract by like terms so:

[tex]14x + 8y = 1794\\-8x - 8y = -1272[/tex]

This leaves us with 6x=522 now you would divide by 6 to isolate x which leaves you with 87.

Answer:

0.68 inches (nearest hundredth)

Step-by-step explanation:

First, find the length on the map that represents 1 mile of the subway.

677 miles ----- 4.1 inches

1 mile ----- 4.1 ÷ 677= 0.0060561 inches (5 s.f.)

Multiply both sides by 113:

113 miles ----- 113(0.0060561)= 0.68 inches (nearest hundredth)

Thus, the length of the subway on the map is 0.68 inches.

Answer:

(2,4)

X always comes before Y. So the X is 2 and the Y is 4, so (2,4).

Answer:

m∠y = 50 (Due to A)

m∠x = 50 (Due to F)

Step-by-step explanation:

Due to corresponding angles,

x = y = 50

Also, another thing... You wrote 60 degrees as your answer for the first part, you did a slight miscalculation.

180 - 130 = 50

So the answer for the first part is 50 degrees. However, the reasoning is correct!

Answer:

65 and 325

Step-by-step explanation:

(l+w)*2 = 780

l+w = 390

l = 5w

5w + w = 390

6w = 390

w = 65

length = 325

Step-by-step explanation:

Since Q and R are complementary,

⇒ Q + R = 90°

Since Q is 26° less than the measure of R

⇒ R - 26° = Q

We can therefore say that ( R - 26°) + R = 90°

⇒              2 R = 90° + 26°

                    R = 58 °

Also, since  R - 26°   = Q

                   58° - 26° =  Q

                            32 ° = Q

We want to find the total change in the volume of water of a tub, given that we know how much water is used.

The change in volume is: -(9 + 7/10) quarts.

To find the change in volume, we need to find the total volume of water used.

We do know that:

The total amount used is the sum of the two quantities above, we get:

(3 + 1/5) quarts + (6 + 1/2) quarts

(3 + 6 + 1/2 + 1/5) quarts

(9 + 7/10) quarts.

So the change in volume is related to this, and we should write:

Final Volume - Initial Volume = -(9 + 7/10) quarts.

Where the negative sign is because at the end we have less volume than at the beginning.

Answer:

Part A - Represents a function

Part B - Doesn't represent a function.

Step-by-step explanation:

A set is just a list of numbers to check. The question is asking you based on the set...

(-2, -6)

(-1, 8)

(4,6)

if it is a valid function.

At NO point should a function have multiple x values. This fails the Vertical Line Test if visualized on a graph.

For Part A, there are no duplicate x values, meaning this function is valid.

For Part B, there is a duplicate x value - (2,9) & (2,4). Because of this, immediately the function is invalid. There can not be any duplicate x values in a valid function, PERIOD. If graphed, it fails the vertical line test.

Answer:

x = 5/3

Step-by-step explanation:

Solve for x:

3 x + 5 = 10

Subtract 5 from both sides:

3 x + (5 - 5) = 10 - 5

5 - 5 = 0:

3 x = 10 - 5

10 - 5 = 5:

3 x = 5

Divide both sides of 3 x = 5 by 3:

(3 x)/3 = 5/3

3/3 = 1:

Answer:  x = 5/3

Step-by-step explanation:

To solve for x, make it the subject of the equation and simplify:

3x + 5 = 10      [subtract five from both sides]

     3x = 5        [divide both sides by three]

       x = ⁵/₃

Answer:

[tex]\boxed{Hiya!}[/tex]

[tex]\text{My Answer would be A. 90}[/tex]

Step-by-step explanation:

If you Look at the shape closely We can see that it is a right triangle (Figure A)

and Figure B is turned upside down. So if we turn the right angle counterclock wise 90° We would end up with (Figure A) looking the same as (Figure B)

Recall the triple angle identity for sine:

sin(3x) = 3 sin(x) cos²(x) - sin³(x)

… = 3 sin(x) (1 - sin²(x)) - sin³(x)

… = 3 sin(x) - 4 sin³(x)

So the equation is equivalent to

sin²(x) - 2 sin(x) + 2 = sin²(3x)

sin²(x) - 2 sin(x) + 2 = (3 sin(x) - 4 sin³(x))²

sin²(x) - 2 sin(x) + 2 = 9 sin²(x) - 24 sin⁴(x) + 16 sin⁶(x)

16 sin⁶(x) - 24 sin⁴(x) + 8 sin²(x) + 2 sin(x) - 2 = 0

or, by replacing y = sin(x),

16y ⁶ - 24y ⁴ + 8y ² + 2y - 2 = 0

By inspection, y = 1 is a root, since

16 - 24 + 8 + 2 - 2 = 0

so we get one family of solutions,

sin(x) = 1   ===>   x = arcsin(1) + 2nπ = π/2 + 2nπ

Now suppose y ≠ 1. Dividing both sides of the sextic equation by y - 1 then gives

(16y ⁶ - 24y ⁴ + 8y ² + 2y - 2)/(y - 1) = 0

16y ⁵ + 16y ⁴ - 8y ³ - 8y ² + 2 = 0

Unfortunately, the remaining roots can only be obtained through numerical methods. Using a calculator, you would find

y ≈ -1.127

y ≈ -0.475 ± 0.368i

y ≈ 0.539 ± 0.127i

But if you're solving over the reals, you can ignore these solutions. Remember that sin(x) is bounded between -1 and 1, and its value goes outside this interval only when x is complex.
