Drag each label to the correct location on the figure. Not all labels will be used. Find the missing angle measurements. 60° 64° 45° 49° 53° 56° 64° 719
Answers
we know that
In any triangle the sum of the interior angles must be equal to 180 degrees
so
In the first triangle (bottom) we have
64+71+x=180
Solve for x
x is the missing angle
135+x=180
x=180-135
x=45 degrees
The first missing angle is 45 degrees
step 2
triangle of the top
we know that
The first missing angle is 64 degrees by vertical angles
so
we have that
64+56+y=180
solve for y
120+y=180
y=180-120
y=60 degrees

There are three groups in a community. Their demand curves for public television in hours of programming, T, are given respectively by Wy = 200-T W2 = 240-T W3 = = 320-T Suppose public television is a pure public good that can be produced at a constant marginal cost of $200 per hour. What is the efficient number of hours of public television?
Answers
In such a competitive private market, 80 hours of programming would be available.
What is defined as the Marginal Social Benefit?The marginal social benefit is the difference with in benefits of consuming one more unit of a product or service. It is determined by the amount of money individuals are inclined to pay for an extra unit of a good or service. When marginal benefit corresponds marginal cost for all groups, the efficient amount of hours of public television is reached.For the given question;
Marginal social benefit = Addition of all groups with in community.
MSB = W1 + W2 + W3
MSB = ($200 - T) + ($240 - 2T) + ($320 - 2T)
MSB = $200 + $240 + $320 - T - 2T - 2T
MSB = $760 - 5T
Calculate efficient number of hours for the public television:
MSB = MC
$760 - 5T = $200
$760 - $200 = 5T
5T = $560
T = 112 hours for the programming.
b. For $200 per hour,
Demand for group 1:
Private marginal benefit = Private marginal cost
$200 - T = $200
T = 0 hours for the programming.
Demand for group 2:
$240 - 2T = $200
$240 - $200 = 2T
$40 = 2T
T = 20 hours for the programming.
Demand for group 3:
$320 - 2T = $200
$320 - $200 = 2T
$120 = 2T
T = 60 hours for the programming.
Hours of television = group 1 + group 2 + group 3
Hours of television = 0 + 20 + 60
Hours of television = 80 hours
Thus, in such a competitive private market, 80 hours of programming would be available.

EXPLANATION
Given that the slant represents the diagonal side of a solid, we can use the Pythagorean Theorem as shown as follows:
Thus, if we know the height and the base, we can compute the slant height by the Pythagorean as explained above.
The Pythagorean Theorem says:
Therefore, we can substitute the radius and the height in the Pytagorean Equation to obtain the slant height.
[tex]\text{radius}^2+\text{height}^2=\text{slant height\textasciicircum{}2}[/tex][tex]r^2+h^2=s^2[/tex]Pluggin in the given values into the equation:

The solution to the inequality 5x - 25 > -15 in inequality and interval notation form are x > 2 and (2,∞)
How to solve linear inequality problems?A linear inequality is simply an expression where two values are compared by the inequality symbols <, >, ≤ or ≥.
Given the data in the question;
5x - 25 > -15
To solve for x, bring all terms containing the variable to the left side of the equation and the terms without variables to the right side of the equation.
5x - 25 > -15
Add 25 to both sides
5x - 25 + 25 > -15 + 25
5x > -15 + 25
5x > 10
Divide each term in 5x > 10 by 5 and simplify.

Based on the definition of the midpoint of a line segment, the length of UV is determined as: 16 units.
What is the Midpoint Definition of a Segment?The midpoint of a segment is defined as the point on a line segment where the line segment is bisected into two equal smaller segments. The length of the smaller segments formed will be equal to each other.
Given that V is the midpoint of segment UW, it means that V divides segment UW into two equal smaller segments, UV and VW.
UV = 2x
VW = x + 8

A group of 45 people attended a ball game. There were twice as many children as adults in the group, Set up a system of equations that represents the numbers of adults and children who attended the game and solve the system to find the number of children who were in the Group
Answers
Answer:
There are 15 adults and 30 children
Step-by-step explanation:
Hey there!
Setting up the system of equations
----------------------------------------------------------------------------------------------------------
Lets first set a variable for the children and adults
Children - x
Adults - y
x + y = 45
x = 2y
----------------------------------------------------------------------------------------------------------
Solving the system of equations
----------------------------------------------------------------------------------------------------------
We can use substitution
(2y) + y = 45
3y = 45
y = 15
This means, there are 15 adults
Now we plug in this information
x = 2y
x = 2(15)
x = 30
This means, there are 30 children
----------------------------------------------------------------------------------------------------------
So, there are 15 adults and 30 children
