Using the midpoint formula, the coordinates of the intersection of the diagonals of the parallelogram is: (1, 2.5).

The diagonals of a parallelogram bisect each other, therefore, the coordinates of their intersection can be determined using the midpoint formula, which is: [tex]M(\frac{x_2 + x_1}{2}, \frac{y_2 + y_1}{2})[/tex].

A diagonal is XZ.

X(2, 5) = (x1, y1)

Z(0, 0) = (x2, y2)

Answer:

x = 7.5 km/h

Step-by-step explanation:

• First calculate the distance covered by walking at 3 km/h for 45 minutes ( 0.75 h):

distance = speed × time

              = 3 × 0.75

              = 2.25 km

• Therefore, she covered 2.25 km of the total journey by walking. Since she was 6 km from the starting point at the end of the entire journey, we can calculate the distance remaining, which she had to run:

distance she had to run = 6 - 2.25

                                        = 3.75 km

• Now we can calculate the speed of the 30 minute (0.5 h) run:

speed = distance ÷ time

           = 3.75 ÷ 0.5

           = 7.5 km/h    

This means that she ran at 7.5 km/h for half an hour.

∴ x = 7.5

Answer:

Step-by-step explanation:

The given relations between numbers and prices can be used to write a system of equations for the number of each kind of ticket. One equation will describe ticket numbers; the other will describe ticket revenue.

Let x represent the number of adult tickets, and y the number of student tickets. The given relations can be written as the general-form equations ...

  8x -y -11 = 0 . . . . . . . . . ticket numbers

  5x +3y -895 = 0 . . . . . ticket revenue

The setup using general form equations lends itself to solution using the "cross multiplication method." Using this method, we define three numbers used in the solution:

  Δ = 8(3) -5(-1) = 24 +5 = 29

  Δx = -1(-895) -3(-11) = 895 +33 = 928

  Δy = -11(5) -(-895)(8) = -55 +7160 = 7105

And the solutions are ...

  x = Δx/Δ = 928/29 = 32

  y = Δy/Δ = 7105/29 = 245

32 adult tickets and 245 student tickets were sold.

The volume of the piece of the metal Gina is found to be 22.82 cubic cm.

Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of cube or cuboid.

Given the density of the metal = 9.2g/cm3

Given the mass of the piece of the metal = 210 g

Assuming the volume of a piece of metal to be V

The expression for the density is shown below:-

Density = Mass / Volume

9.2 = 210 / V

V = 210 / 9

V =  22.82 cubic cm.

Therefore the volume of the piece of the metal Gina is found to be 22.82 cubic cm.

The complete question is given below:-

Gina was given an irregularly shaped piece of metal and was told that the density of the metal was 10 g/cm3. She measured the mass of the piece to be 210 g. What was the volume of the piece of metal Gina was given?

b. If the common stock had a market price of $510 per share before the stock split, the approximate market price per share after the split is $255 ($510/2).

A stock split is a way that a corporation increases the number of its shares by increasing or decreasing the number of shares outstanding.

When a stock split increases the number of outstanding shares, the market price reduces proportionately.

a. What will be the number of shares outstanding after the split? Round your answer to the nearest whole number.

b. If the common stock had a market price of $510 per share before the stock split, what would be an approximate market price per share after the split? Round your answer to the nearest dollar.

Answer:

15.47 degrees

Step-by-step explanation:

By using trigonometric properties, we will see that:

tan(x) = 3/4.

Remember that the sine of the difference is:

sin(a - b) = sin(a)*cos(b) - sin(b)*cos(a).

Here we have:

sin(90° -x ) = 0.8

Expanding the sine:

sin(90° - x) = sin(90°)*cos(x) - sin(x)*cos(90°)

We know that:

sin(90°) = 1 and cos(90°) = 0, then:

sin(90° - x) = sin(90°)*cos(x) - sin(x)*cos(90°) = cos(x).

Then we have:

cos(x) = 0.8

And we want to find the tangent of x, which is:

[tex]tan(x) = \frac{sin(x)}{cos(x)}[/tex]

We already know that cos(x) = 0.8

Now, remember that:

[tex]sin(x)^2 + cos^2(x) = 1\\\\sin(x) = \sqrt{1 - cos^2(x)} \\[/tex]

Because x is an acute angle, sin(x) > 0, that is why we choose the positive root.

Replacing cos(x) we get:

[tex]sin(x) = \sqrt{1 - 0.8^2} = \sqrt{1 - 0.64} = \sqrt{0.36} = 0.6[/tex]

Then the tangent of x is:

[tex]tan(x) = \frac{0.6}{0.8} = \frac{6}{10}*\frac{10}{8} = 6/8 = 3/4[/tex]

Answer:

60 Days.

Step-by-step explanation:

Alright. We're told that the elementary menu repeats every 20 days. All right. And the middle school repeats every 15 days. And today they're both serving pizza. It asks how long until they're both saving it serving pizza again. Alright. So we can kind of just write them out and say well, if it's every 20 days, it repeats. Well then in 20 days from now we're going to get pizza again. And then after that another 20 days, so 40 days and then after that another 60 days. Okay. And we're just adding 20 each time. Uh you know, to see when would we get pizza again at the elementary school? Well, we can do the same thing here with middle school. And when are they going to get pizza again? Well, in 15 days from now they would get pizza again and then another 15 days from that. So that's 30 And then 45 and then 60 and then 75 and so on. And the first time that they're going to repeat is well, this is the common factor that are the common multiple that they have, which is 60. This is really just a complicated way of asking what is the least common multiple of 20 and 15. Alright. And your answer is going to be 60. So it'll be 60 days until they serve the same pizza again.

Answer:

m∠R = 112°

m∠S = 112°

m∠T = 68°

Step-by-step explanation:

Quadrilateral QRST is a cyclic quadrilateral.

A cyclic quadrilateral is a quadrilateral drawn inside a circle where every vertex touches the circumference of the circle.  

The opposite angles in a cyclic quadrilateral sum to 180°.

⇒ m∠Q + m∠S = 180°

⇒ m∠R + m∠T = 180°

Given:

Measure of angle Q

⇒ m∠Q + m∠S = 180°

⇒ 68° + m∠S = 180°

⇒ m∠S = 180° - 68°

⇒ m∠S = 112°

Measure of angles R and T

⇒ m∠R + m∠T = 180°

⇒ (3x + 40)° + (5x - 52)° = 180°

⇒ )8x -12)° = 180°

⇒ 8x° = 192°

⇒ x = 24

Substituting the found value of x into the expressions for angles R and T:

⇒ m∠R = (3(24) + 40)°

⇒ m∠R = 112°

⇒ m∠T = (5x - 52)°

⇒ m∠T = 68°

Explanation:

This is the given piecewise function

[tex]h(a) = \begin{cases}3a+2 \text{ when } a > 3\\4a+5 \text{ when } a = 3\\3 \text{ when } a < 3\\\end{cases}[/tex]

We can rewrite things like this

[tex]\text{when } a > 3, \ \ h(a) = 3a+2\\\text{when } a = 3, \ \ h(a) = 4a+5\\\text{when }a < 3, \ \ h(a) = 3\\[/tex]

I personally prefer this format better because it mentions the inputs first, and that leads to which function definition we go for.

The input a = 2 fits the description of [tex]a < 3[/tex] since [tex]2 < 3[/tex] is a true statement. Therefore we go for the third line and can see that [tex]h(a) = 3[/tex] becomes [tex]h(2) = 3[/tex]

-----------

As another example, if we had the input a = 7, then we'd go for the first line (since 7 > 3) and get

h(a) = 3a+2

h(7) = 3(7)+2

h(7) = 23
