Answer:
x = 6 , y = 4
Step-by-step explanation:
for the figure to be a parallelogram , the opposite sides must be congruent, that is
5y = 20 ( divide both sides by 5 )
y = 4
and
2(x + y - 1) = x + 3y ← distribute parenthesis on left side by 2
2x + 2y - 2 = x + 3y ← substitute y = 4
2x + 2(4) - 2 = x + 3(4)
2x + 8 - 2 = x + 12
2x + 6 = x + 12 ( subtract x from both sides )
x + 6 = 12 ( subtract 6 from both sides )
x = 6
The children's reading room of a library is shaped like a triangle. Two perpendicular sides of the room measure 12 feet and 17 feet. What's the area of the room?
a.29 squared feet
b.102 squared feet
c.120 squared feet
d.204 squared feet
Answer: B 102
Step-by-step explanation: The perpendicular sides of the room tells us that it is a right triangle.
To find our the area of the triangle you use the formula [tex]\frac{base*height}{2}[/tex]base*height/2
We plug in 12feet and 17 feet for the base and height
We get [tex]\frac{12*17}{2}[/tex]
12 and 2 cancel out so our new equation is 6*17 squared feet
So our answer is 102 square feet

In a village of 320 adults, each of them does at least farming or trading. 5/8 of them do farming and 75% of these who do farming are involved in trading. a. Find the number of people who are involved in: i. Farming ii. Trading. b. How many of the people are involved in exactly two activities?
c. Find the number of people who do only one activity.
d. What percentage of the people are traders only?
e. What is the probability of selecting an adult from the village at random who is a farmer but not a trader?
Answer:
please see answers below
Step-by-step explanation:
i) 5/8 X 320 = 200 people
ii) 0.75 X 200 = 150 (people in farming but also trade). only trade = 320 - 200 = 120.
number of people in trade = 150 + 120 = 270.
b) 0.75 X 5/8 = 3/4 X 5/8 = 15/32 = 150 people (both farm and trade).
c) only farming = 0.25 X 5/8 = 1/4 X 5/8 = 5/32 = 50.
only trade = 320 - 50 (only farm) - 150 (both farm and trade) = 120.
so, only do one activity = 50 + 120 = 170.
d) traders only = 120/320 = 3/8 = 37.5%
e) P(farmer only) = 50/320 = 0.15625
What is the minimum selling price on the special order to produce net income of 5.17 per basketball
The minimum selling price on the special order to produce net income of 5.17 per basketball is $ 29.79 per ball.
How to calculate the valueVariable cost of goods sold for the special order = $ ( 3,582,000 - 960,000 ) / 120,000 * 10,000 = $ 218,500
Variable selling and administrative expenses for special order = $ [( 513,400 - 271,000) / 120,000 + 0.75] x 10,000 = $ 27,700
Fixed costs are not relevant, as they would remain unchanged.
c. Profit required = $ 5.17 x 10,000 = $ 51,700
Minimum selling price required = $ ( 51,700 + 218,500 + 27,700) / 10,000
= $ 29.79 per ball.

Answer: 99 in²
Step-by-step explanation:
We can use the given formula for a triangular prism. We will substitute our known values and solve.
Surface Area = length * base perimeter + (2 × base area)
Surface Area = length * (1.5 in + 2 in + 2.5 in) + (2 × [tex]\frac{bh}{2}[/tex])
Surface Area = 16 * (6 in) + (2 × [tex]\frac{(2\;in)(1.5\;in)}{2}[/tex])
Surface Area = 16 in * (6 in) + (3 in²)
Surface Area = 96 in² + 3 in²
Surface Area = 99 in²
find exact value sin 9pie/ 4
The exact value of expression sin 9π/4 is,
⇒ sin 9π/4 = 1 / √2
We have to given that;
Expression to find exact value is,
⇒ sin 9π/4
Now, WE can change it into degree as,
⇒ 9π/4
⇒ 9 × 180 / 4
⇒ 9 × 45
⇒ 405 degree
Hence, We get;
⇒ sin 9π/4
⇒ sin 405°
⇒ sin (360 + 45°)
⇒ sin 45°
⇒ 1 / √2
Thus, The exact value of expression sin 9π/4 is,
⇒ sin 9π/4 = 1 / √2

Yes, children, students, and senior citizens being eligible for discounted movie tickets is an example of price discrimination.
What is price discrimination?When a merchant charges different rates to various groups of clients based on their willingness to pay, this is referred to as price discrimination.
Price discrimination requires market strength, definable client segmentation, and the capacity to avoid arbitrage among various groups.
Price discrimination is a sales approach in which the seller charges varying rates for the same product or service based on what the vendor believes the consumer would agree to.

Meera can sell 1 jacket for $40, 2 jackets for $35 each, 3 jackets for $30 each, 4 jackets for $25 each, and 5 jackets for $20 each. Her marginal cost of production is constant at $20 for each additional unit (or jacket) produced. If she behaves like a monopolist, what is the number of jackets she will sell?
a. 1
b. 3
c. 4
d. 5
The number of jackets Meera will sell if she behaves like a monopolist is 3( option B).
To determine the number of jackets Meera will sell if she behaves like a monopolist, we need to compare the marginal revenue (MR) and marginal cost (MC) of producing and selling additional jackets. Meera can sell jackets at various price points depending on the quantity sold, but as she behaves like a monopolist, we consider the revenue and costs associated with a given production level.
From the pricing information given, we can determine her total revenue function, R(x), as follows:
- For 1 jacket, R(1) = 40
- For 2 jackets, R(2) = 70
- For 3 jackets, R(3) = 90
- For 4 jackets, R(4) = 100
- For 5 jackets, R(5) = 100
To determine her marginal revenue function, MR(x), we find the change in revenue from selling an additional jacket. From the data given, we can see that MR is not constant and decreases as the quantity sold increases. Specifically:
- For 1 jacket, MR(1) = 40 - 0 = 40
- For 2 jackets, MR(2) = 35 - 40 = -5
- For 3 jackets, MR(3) = 30 - 35 = -5
- For 4 jackets, MR(4) = 25 - 30 = -5
- For 5 jackets, MR(5) = 20 - 25 = -5
Meera's marginal cost of production is given as a constant $20 for each additional jacket produced, so MC(x) = 20 for all values of x.
To maximize her profits, Meera should produce and sell jackets up to the point where MR(x) = MC(x), which represents the level of production that equates the revenue from selling an additional jacket with the cost of producing that jacket. This happens at the output level of 3, where MR(3) = -5 = MC(3) = 20.(option-b)

Find the slope of the line that passes through the two points on the graph above. A. -5.13 B. -0.87 C. 0 D. 0.87
The slope of the line that passes through given points is -0.87. Option B is the correct answer.
In mathematics, slope is usually defined by the letter "m" and includes the change in y coordinate (vertical change) divided by the change in x coordinate (horizontal shift) between two points on a line.
We know that slope of a line that passes through two points is :
slope, [tex]m = \frac{y_{2} - y_{1} }{x_{2}-x_{1} }[/tex]
The given points are (-3.9,4.1) and (5.5,-4.1).
y2 = -4.1
y1 = 4.1
x2 = 5.5
x1 = -3.9
Substituting all these values in the above equation we get,
slope, [tex]m = \frac{-4.1 - (4.1)}{5.5 - (-3.9)}[/tex]
m = -8.2 / 9.4
m = -0.87
So, the slope of the line formed by given points is -0.87. Therefore , option B is correct answer.
