The average cost of a movie ticket in Japan is $17.99 and in Switzerland is $13.82.
To solve the problem of determining the average cost of a movie ticket in Japan and Switzerland, we need to set up a system of equations based on the information given. If we let J represent the cost of a ticket in Japan and S represent the cost of a ticket in Switzerland, we can formulate the following equations from the scenario provided:
3J + 2S = $81.61 (Cost for three tickets in Japan and two in Switzerland)
3S + 2J = $77.44 (Cost for three tickets in Switzerland and two in Japan)
Now we solve the system of equations using substitution or elimination method. For simplicity, we'll use the elimination method:
Multiply the first equation by 3 and the second equation by 2 to make the coefficients of S the same:
9J + 6S = 3 x $81.61 = $244.83
6S + 4J = 2 x $77.44 = $154.88
Subtract the second new equation from the first to eliminate S:
9J + 6S - (6S + 4J) = $244.83 - $154.88
5J = $89.95
Divide by 5 to solve for J:
J = $89.95 / 5 = $17.99
Now substitute the value of J in either original equation to solve for S:
3(17.99) + 2S = $81.61
53.97 + 2S = $81.61
2S = $81.61 - 53.97
2S = $27.64
Divide by 2 to solve for S:
S = $27.64 / 2 = $13.82
Therefore, the average cost of a movie ticket in Japan is $17.99 and in Switzerland is $13.82.

Valerie's younger sister is 3 ft 2 in. tall. if her sister grows an additional 32 inches how tall will she be
Answer:
6 feet 4 inches
Step-by-step explanation:
Step-by-step explanation:
3 FEET 2 INCHES These are not the same! Do not multiply
Each foot is 12 inches. So 3 times 12 (3 feet) is 36, add the extra 2 inches for 38 inches.
38 plus 32 equals 70 total inches. NOw we put it back into feet.
70 divided by 12 is 5, remainder 10.
So Valerie's sister will be 5 feet 10 inches (G)

David’s garden produced six bushels of zucchini, three bushels of beans, seven bushels of corn, and four bushels of beets. In the table below, write the fraction (in simplest form) and the percent of David’s total crop that each vegetable represents.
Answer:
Step-by-step explanation:
Zucchini = 'z' = 6
Beans = 'b' = 3
Corn = 'c' = 7
beets = 't' = 4
Total produce = 20 bushels of veggies.
z = 6/20 = 3/10 % = 3/10*100 = 30%
b = 3/20 % = 3/20 * 100 = 15%
c = 7/20 % = 7/20 *100 = 35%
t = 4/20 = 1/5 % = 1/5 * 100 = 20%
Total 100%
The fourth term of a sequence is 14. Each term of the sequence is 8 less than the previous term. Which recursive formula represents the situation?
So
an=an+b
14=4a+b and a=-8
14=-32+b
b= 46
an=-8n+46
Answer with Step-by-step explanation:
[tex]a_{4}=14[/tex]
Each term of the sequence is 8 less than the previous term
⇒ [tex]a_{3}=14+8=22[/tex]
⇒ [tex]a_{2}=22+8=30[/tex]
⇒ [tex]a_{1}=30+8=38[/tex]
In general [tex]a_{n}=a_{n-1}-8,a_{1}=38[/tex]
Hence, recursive formula representing the situation is:
[tex]a_{n}=a_{n-1}-8,a_{1}=38[/tex]
Find the mean absolute deviation. Round to the tenth
Answer:
1) 1.8 round to tenths
Step-by-step explanation:
To find the mean absolute deviation we follow these steps:
Find the mean value by adding all data values and dividing by number of data valuesFind the absolute value of the difference between each data value and the mean: | data value – mean. | Divide the sum of the absolute values of the differences by the number of data values1) 4,5,10,8,4,8,7,6
step 1
4+5+10+8+4+8+7+6 / 8 = 6.5
Mean (μ): 6.5
step 2
|4-6.5| + |5-6.5| + |10-6.5| + |8-6.5| + |4-6.5| + |8-6.5| +|7-6.5| + |6-6.5| = 14
step 3
14 / 8 = 1.75
Repeat these steps for other parts.

Frederick headed for Lutzen at 3 kph. Later he increased his speed to 4 kph. If it was 52 kilometers to Lutzen and the total time of travel was 15 hours, how long did he travel at 3 kph?
Since distance is equal to rate times time:
Let x= the time traveled at 3 km/h
Let y= the time traveled at 4 km/h
We can say that
3x+4y=52
Or that three (kilometers) times the time traveled at 3 kilometers an hour plus 4 (kilometers) times the time traveled at 4 kilometers an hour is equal to 52; the total distance traveled.
Likewise, we can see that:
x+y=15
Because x, the number of hours traveled at 3 km/h added to y, the time traveled at 4 km/h is equal to 15; the total time traveled.
Now, I'll solve by substitution.
x=-y+15
Substitute that into the other equation.
3(-y+15) + 4y = 52
Distribute
-3y + 45 + 4y = 52
Combine like terms
y + 45 = 52
Minus 45 from both sides
y = 7
So Fredrick traveled at 4 km/h for 7 hours.
Now, to find the other value, substitute the value of y into one of the original equations.
x + 7 = 15
Minus 7
x = 8
So
Time traveled at 4 km/h = 7 hours
Time traveled at 3 km/h = 8 hoursSince distance is equal to rate times time:
Let x= the time traveled at 3 km/h
Let y= the time traveled at 4 km/h
We can say that
3x+4y=52
Or that three (kilometers) times the time traveled at 3 kilometers an hour plus 4 (kilometers) times the time traveled at 4 kilometers an hour is equal to 52; the total distance traveled.
Likewise, we can see that:
x+y=15
Because x, the number of hours traveled at 3 km/h added to y, the time traveled at 4 km/h is equal to 15; the total time traveled.
Now, I'll solve by substitution.
x=-y+15
Substitute that into the other equation.
3(-y+15) + 4y = 52
Distribute
-3y + 45 + 4y = 52
Combine like terms
y + 45 = 52
Minus 45 from both sides
y = 7
So Fredrick traveled at 4 km/h for 7 hours.
Now, to find the other value, substitute the value of y into one of the original equations.
x + 7 = 15
Minus 7
x = 8
So
Time traveled at 4 km/h = 7 hours
Time traveled at 3 km/h = 8 hours

Select all the expressions equivalent to 3.1⁴.
Answer:
A, B, DStep-by-step explanation:
[tex]3.1^4=(3.1)(3.1)(3.1)(3.1)\to\boxed{A}\\\\3.1^4=[(3.1)(3.1)](3.1)(3.1)=(9.61)(3.1)(3.1)\to\boxed{B}\\\\3.1^4=[(3.1)(3.1)][(3.1)(3.1)]=(9.61)(9.61)\to\boxed{D}[/tex]
Equivalent expressions to 3.1⁴ involve raising 3.1 to the power of 4. This means 3.1 is multiplied by itself four times, not three times (which would be cubing). The equivalent expression would result from multiplying 3.1 by itself four times.
Explanation:The equivalent expressions to 3.1⁴ involve the operation of raising a number to a power. In this case following the number 3.1, the exponent of 4 means that 3.1 is being multiplied by itself four times, and it is not the same as cubing. The cubing of exponentials refers to the process of raising a number to the power of three or multiplying the number by itself three times. The commutative, associative, and distributive laws can be applied to simplify and rewrite exponential expressions. Therefore, to find an equivalent expression for 3.1⁴, you would need to multiply 3.1 by itself four times.

Triangle ABC ≅ DEF. Each side of triangle ABC is 1.5 times longer than the corresponding sides of triangle DEF. If the perimeter of triangle ABC is 36 centimeters, what is the perimeter of triangle DEF?
Answer:
Step-by-step explanation:
see attachment
Final answer:
The perimeter of triangle DEF is 24 centimeters.
Explanation:
The perimeter of a triangle is the sum of the lengths of its three sides. In this case, triangle ABC is congruent to triangle DEF, and each side of triangle ABC is 1.5 times longer than the corresponding side of triangle DEF. Let's assume the lengths of the corresponding sides of triangle DEF are x, y, and z. Therefore, the lengths of the corresponding sides of triangle ABC are 1.5x, 1.5y, and 1.5z.
Since the perimeter of triangle ABC is 36 centimeters, we can set up the equation as follows: 1.5x + 1.5y + 1.5z = 36. Simplifying the equation, we get x + y + z = 24. This means the perimeter of triangle DEF is 24 centimeters.

How do I find the perimeter?
Answer:
8x³ - 5x² + 8x
Step-by-step explanation:
to solve the perimeter, you need to add all sides of the triangle together.
8x² + x³ + 2x² + 7x³ - 3x² + 6x
now, code all the similar variables:
8x² + x³ + 2x + 7x³ - 3x² + 6x
8x² - 3x² = 5x²
x³ + 7x³ = 8x³
2x + 6x = 8x
so, put them all together:
5x² + 8x³ + 8x
but remember that the larger exponent comes first(just a rule)
so, it is : 8x³ - 5x² + 8x

Classify the quadrilateral. Then find the value(s) of the variable(s).
Answer:
Its A
Step-by-step explanation:
solve this equation
5(-7x-3)- 8x=-230
Simplifying
5(7x + -3) = 230
Reorder the terms:
5(-3 + 7x) = 230
(-3 * 5 + 7x * 5) = 230
(-15 + 35x) = 230
Solving
-15 + 35x = 230
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 35x = 230 + 15
Combine like terms: -15 + 15 = 0
0 + 35x = 230 + 15
35x = 230 + 15
Combine like terms: 230 + 15 = 245
35x = 245
Divide each side by '35'.
x = 7
Simplifying
x = 7

Two lines intersecting at a right angle ?
Answer:
are perpendicular
Yes, it is perpendicular
Parallel is when you have two lines that do not intersect
A ray is a line that has one definite starting point and no obvious end point. (Stars with a point and "ends" with an arrow, meaning that it goes on "forever")
A line is just one specific line
When you have perpendicular, that is when two lines cross each other forming a right angle as you may now know
