The missing value of inverse variation is 0.5
What is inverse variation ?The inverse variation property states that , whenever the product of values of two quantities is a constant value then there is opposite variation between these two corresponding values. Or we can also say that if the productive nature of two corresponding values is constant, then one quantity is inversely varies with second quantity.
Let say if x and y are two values and k is a constant value, then
According to inverse variation
k = xy or y = k/x
In the given question,
Take the order pair (4,1.5)
As it is an inverse variation, we can substitute it
y=k/x
1.5=k/4
K=6
Now find the inverse variation equation
y=k/x
Also, k=6
Solve this equation for the second pair (x,12)
As, y=6/x
x = 6/12 = 1/2 = 0.5
Therefore, missing value is 0.5

Juan’s game board is a square with sides that are 50 cm long. the area of the large circle is about 1,963.5 square cm. what is the geometric probability that juan will score more than 0 points? 0 0.215 0.785 1
The geometric probability that Juan will score more than 0 points = 0.785
Juan's game board consists of a square with a circle inscribed in it.
If he hits the circle, then he can score more than 0 points.
Length of side of the square = 50 cm
So area of the square = 50 x 50 = 2500 square cm.
Now the area of the large circle = 1963.5 square cm.
Geometric probability that Juan will score more than 0 points
= Area of the circle / Area of the square
= 1963.5/2500
= 0.785

The number of hours parked for the cost of each garage to be the same is 3 hours.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let t represent the number of hours parked at either garage A or garage B. Hence:
Total charges at garage A (A) = 5t + 11
A = 5t + 11
Total charges at garage B (B) = 6t + 8
B = 6t + 8
If both garages have the same cost:
5t + 11 = 6t + 8
t = 3
The number of hours parked for the cost of each garage to be the same is 3 hours.

How many at-the-door tickets must he sell to make his goal?
350
300
200
100
The number of at-the-door tickets that must be sold to reach the goal is 100.
How many at the door tickets must be sold to reach the goal?The system of linear equations that can be used to determine the required values are:
10p + 15d = $3500 equation 1
p + d = 300 equation 2
Where:
p = number of pre-sale tickets sold d = number of at-the-door tickets soldTo determine the value of d, take the following steps:
Multiply equation 2 by 10
10p + 10d = 3000 equation 3
Subtract equation 3 from equation 1
5d = 500
Divide both sides of the equation by 5
d = 500 / 5
d = 100

Given that the expression is [tex]log_{2}\sqrt{x}[/tex].

Find the inverse of each function. Is the inverse a function?
y=3 x²-5
The inverse function returns the original value for which the output of a function was given
The inverse of this function is x = [tex]$\sqrt{\frac{y+5}{3} }[/tex]
What is the inverse formula?The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x.
If y varies inversely as x and x = 5 when y = 2, the constant of variation is k = xy = 5(2) = 10.
As a result, the equation for this inverse variation is xy = 10 or y = 10/x. Write an equation describing the inverse variation of y if it varies inversely as x and y = 6.
When x = 6, k = (6) = 8.
Let the function be y = 3x² - 5
y = 3x² - 5
Switch sides and add 5 to both sides
3x² = y + 5
Divide both sides by 3
x² = y + 5/3
Take the square root of both sides
x = ± [tex]$\sqrt{\frac{y+5}{3} }[/tex]
x = [tex]$\sqrt{\frac{y+5}{3} }[/tex]
Therefore, the value of x = [tex]$\sqrt{\frac{y+5}{3} }[/tex]

Yes, there is a probability that there are some very high wages that strongly increases the average wage in Los Angeles like the wages of highly paid famous actors and actresses and some computer programmers in places like Silicon Valley.
This increases the gap between the highly paid and the low-income earners. As a result, finding the average gives a value that is below the average wage for that city.
The average annual wage in Los Angeles is Approximately $66,966 which narrows down to roughly $32.20 an hour. To calculate an average wage, we add all wages earned monthly, yearly or quarterly and divide by the number of workers registered.

solve: |x + 11 | = x + 11
Answer: x>=-11
Step-by-step explanation:
|x + 11 | = x + 11
x+11=x+11 ==> x+11>0 since absolute value functions are greater than 0
x=x when x+11>0
x+11>0
x+11-11>0-11
x>-11
x+11=-(x+11)
x+11=0 ==> the only time a positive and negative number are equal is when the number itself is 0. Here, the number is 'x+11'.
x+11-11=0-11
x=-11
x=-11 and x>-11 ==> x>=-11

Horatio spends about 40 hours per week reading 2 different books in his spare
time. One book is more difficult, and one is lighter. He reads about 12 pages per
hour of the more difficult book and 25 pages per hour of the lighter book. If he
reads 610 pages per week, how many hours does Horatio spend on each book?
Answer:
you add 40+12+25+2+610 and you will get your answer
Answer:
Horatio spends 30 hours on the more difficult book and 10 hours on the lighter book
Step-by-step explanation:
Let X be the hours spent reading the more difficult book
Let Y be the hours spent reading the less difficult book
Total hours spent = X + Y = 40
Number of pages of difficult book in X hours at 12 pages per hour = 12X
Number of pages of easier book in Y hours at 25 pages per hour = 25Y
Total pages read = 12X + 25Y
So we have two equations in X and Y and we can solve them simultaneously. Equations are:
X + Y = 40 (1)
12X + 25Y = 610 (2)
We can eliminate one of the variable terms by making the coefficients of the other term equal and then subtracting
Multiply (1) by 12 to make X terms equal
12(X + Y) = 12 x 40
12X + 12Y = 480 (3)
Subtract (3) from (2)
(2) - (3)
==> 12X + 25Y - (12X + 12Y) = 610 - 480
==> 12X + 25Y - 12X - 12Y = 130
==> 25Y - 12Y = 130 (12X terms cancel)
==> 13Y = 130
==> Y = 130/13 (divide both sides by 13)
==> Y = 10
Using (1)
X + Y = 40
==> X + 10 = 40
==> X + 10 - 10 = 40 - 10
==> X = 30
So answer:
Horatio spends 30 hours on the more difficult book and 10 hours on the lighter book
