Average movie ticket cost in Japan = $17.23

Average movie ticket cost in Switzerland = $ 13.52

Step-by-step explanation:

Let <em>x</em> be the cost of movie ticket in Japan and <em><u>y</u></em> be the cost of movie ticket in Switzerland.

Given 3 ticket in Japan + 2 tickets in Switzerland = $78.73

              ⇒ 3<em>x</em> + 2<em>y</em> = 78.73 – – – – (1)

Given 3 ticket in Switzerland + 2 tickets in Japan = $75.02

              ⇒ 3<em>y</em> + 2<em>x</em> = 75.02

              ⇒ 2<em>x</em> + 3<em>y</em> = 75.02– – – – – (2)

Now, to solve (1) and (2), we multiply equation (1) by 2 and equation (2) by 3.

(1) × 2 ⇒       6<em>x</em> + 4<em>y</em> = 157.46 – – – – (3)

(2) × 3 ⇒       6<em>x</em> + 9<em>y</em> = 225.06 – – – – (4)

Subtract (3) from (4), we get

6<em>x </em>+ 9<em>y</em> – (6<em>x</em> + 4<em>y</em>)= 225.06 – 157.46

⇒ 6<em>x</em> + 9<em>y</em> – 6<em>x </em>– 4<em>y</em>= 67.6

⇒ 5<em>y</em> = 67.6

⇒ <em>y</em> = 13.52

Now substitute <em>y</em> = 13.52 in equation (1), we get,

(1) ⇒ 3<em>x</em> + 2(13.52) = 78.73

⇒ 3<em>x</em> = 78.73 – 27.04

⇒ <em>x</em> = 27.23

Hence, Average movie ticket cost in Japan is $27.23

Average movie ticket cost in Switzerland is $ 13.52.

Sandra's scores on the first 4 tests were 87%, 92%, 76%,and 89%. What is the minimum score she needs to make on the fifth test s
sergejj [24]

Answer:

Sandra need to score at least <u>56%</u> in her fifth test so that her average is 80%.

Step-by-step explanation:

Given:

First 4 test scores = 87%, 92%, 76%,89%

Average targeted = 80%

We need to find the minimum score she needs to make on fifth test to achieve average of at least 80%.

Solution:

Let the minimum score she needs to make in fifth test be 'x'.

Total number of test = 5

Now we know that;

Average is equal to sum of all the scores in the test divided by number of test.

framing in equation form we get;

\frac{87+92+76+89+x}{5}=80

Multiplying both side by 5 we get;

\frac{344+x}{5}\times 5=80\times 5\\\\344+x=400

Subtracting both side by 344 we get;

344+x-344=400-344\\\\x=56\%

Hence Sandra need to score at least <u>56%</u> in her fifth test so that her average is 80%.

Use the drop-down menus to complete the proof. by the unique line postulate, you can draw only one segment,
Doss [256]

The reflection of BC over I is shown below.

<h3>What is reflection?</h3>
  • A reflection is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points; this set is known as the reflection's axis (in dimension 2) or plane (in dimension 3).
  • A figure's mirror image in the axis or plane of reflection is its image by reflection.

See the attached figure for a better explanation:

1. By the unique line postulate, you can draw only one line segment: BC

  • Since only one line can be drawn between two distinct points.

2. Using the definition of reflection, reflect BC over l.

  • To find the line segment which reflects BC over l, we will use the definition of reflection.

3. By the definition of reflection, C is the image of itself and A is the image of B.

  • Definition of reflection says the figure about a line is transformed to form the mirror image.
  • Now, the CD is the perpendicular bisector of AB so A and B are equidistant from D forming a mirror image of each other.

4. Since reflections preserve length, AC = BC

  • In Reflection the figure is transformed to form a mirror image.
  • Hence the length will be preserved in case of reflection.

Therefore, the reflection of BC over I is shown.

I need help with ANLGES!!!!
Phantasy [73]

Answer:

32, consecutive interior angles are supplementary.

Step-by-step explanation:

We know that the two angles add up to 180, because consecutive interior angles are supplementary. So let's set up an equation equal to 180.

2x + 3x + 20 = 180

Now let's add like terms.

5x + 20 = 180

Now let's subtract 20 from both sides.

5x = 160

Now let's divide both sides by 5.

x = 32

Answer:

<h2>210 cm³</h2>

Step-by-step explanation:

let V represent the volume of the triangular prism

V = base × height

base = (7×6)/2 = 42/2 = 21

height = 10

then

V = 21×10 = 210

A car drives at a rate of 65 mi/hr. what is the speed of the car in ft/s? note: 1 mi = 5280 ft
lana66690 [7]

Answer:. 95.33 ft/sec

Multiply 65 by 5280 to get 343200 feet per hour. Then Divide by 3600. There are 60 minutes in an hour, and 60 seconds in a minute.

343200 ÷ 3600 = 95.333
