Step-by-step explanation:

The irregular shape is very similar to a trapezium with coordinates (-3,3), (2, 2), (2, -2) and (-3, -4).

Area of a trapezium: [(a+ b)/2]*h

where a and b refer to the two parallel sides and h is the distance between them. From the above coordinates: a = 7 length units, b = 4 length units and h = 5 length units. Therefore, approximate area = [(7+ 4)/2]*5 = 27.5 square units

a baseball team plays 83 games in a season. if the team won 17 more than twice as many as they lost how many times did the did lose?

Answers

Final answer:

By creating an equation based on the information provided and solving for L, which represents the number of games lost, it was determined that the baseball team lost 22 games during the season.

Explanation:

To determine how many games the baseball team lost during the season, let us denote the number of lost games as L. The problem states that the baseball team won 17 more than twice the number of games they lost, which can be expressed as 2L + 17. Since the team played a total of 83 games in the season, we have the following equation to represent the total number of games played:

L + (2L + 17) = 83.

Combining like terms, we get:

3L + 17 = 83.

Now, subtract 17 from both sides of the equation:

3L = 66.

Then, we divide both sides of the equation by 3:

L = 22.

So, the baseball team lost 22 games during the season.

Final answer:

To find the number of times the team lost, set up an equation using the given information. The team won 17 more than twice the number of times they lost. The team lost 22 times.

Explanation:

To find the number of times the team lost, we can set up an equation using the given information.

Let's assume the number of times the team lost is x.

According to the given information, the team won 17 more than twice the number of times they lost. So, the number of times the team won is 2x + 17.

The total number of games played is 83, which is the sum of the number of games won and lost.

So we have the equation 83 = x + (2x + 17).

Simplifying this equation, we get 83 = 3x + 17.

Subtracting 17 from both sides, we have 66 = 3x.

Dividing both sides by 3, we get x = 22.

Therefore, the team lost 22 times.

Suppose that factory a produces 12 tables and 6 chairs an hour while factory b produces 8 tables and 4 chairs and hour. how many hours should each factory work to produce 48 tables and 24 chairs? how many different solutions are there to this problem?

Answers

Factory A should work for 4 hours, while factory B should work for 6 hours to produce 48 tables and 24 chairs

The rates of both factories are given as:

Factory A = 12 tables and 6 chairs in an hour

Factory B = 8 tables and 4 chairs in an hour

To produce 48 tables and 24 chairs, we make use of the following equation

[tex]h = \frac{Produce}{Rate}[/tex]

Where h represents time (in hours)

So, we have:

Factory A

[tex]h = \frac{48\ tables, 24\ chairs}{12\ tables, 6\ chairs}[/tex]

[tex]h = 4[/tex]

Factory A

[tex]h = \frac{48\ tables, 24\ chairs}{8\ tables, 4\ chairs}[/tex]

https://brainly.com/question/19493296

Final answer:

Factory A should work for 0 hours and Factory B should work for 6 hours to produce 48 tables and 24 chairs. There is only one solution to this problem.

Explanation:

To find out how many hours each factory should work to produce 48 tables and 24 chairs, we can set up a system of equations. Let's say that factory A works for x hours and factory B works for y hours. From the information given, we can write the following equations:

12x + 8y = 48 (equation 1, for tables)

6x + 4y = 24 (equation 2, for chairs)

We can solve this system of equations using substitution or elimination method. Let's solve it using the substitution method:

From equation 1, we can isolate x by subtracting 8y from both sides:

12x = 48 - 8y

x = (48 - 8y) / 12

Substituting this value of x in equation 2:

6((48 - 8y) / 12) + 4y = 24

Simplifying the equation:

3(48 - 8y) + 4y = 24

144 - 24y + 4y = 24

-20y = -120

y = (-120) / (-20)

y = 6

Substituting the value of y in equation 1:

12x + 8(6) = 48

12x + 48 = 48

12x = 0

x = 0

Therefore, factory A should work for 0 hours and factory B should work for 6 hours to produce 48 tables and 24 chairs. There is only one solution to this problem.

Final answer:

To find the smallest angle in a right triangle with side lengths of 5.0 m, 12 m, and 13 m, we use the inverse tangent function with the shortest leg over the adjacent leg, yielding an angle of approximately 22.6 degrees.

Explanation:

The subject of the question is mathematics, and it pertains to high school level geometry. The question is asking to determine the smallest angle in a right triangle with sides measuring 5.0 m, 12 m, and 13 m. To find the smallest angle, we can use trigonometry, specifically the inverse tangent function.

Step-by-Step Explanation

Identify the sides of the triangle. In this case, we know that the sides are 5.0 m, 12 m (which could be interpreted as legs), and 13 m (the hypotenuse).

Because we are looking for the smallest angle, we will use the smallest leg, which is 5.0 m, and the next largest leg, which is 12 m.

Use the tangent function, which relates the opposite side to the adjacent side in a right triangle. The smallest angle, which we will call θ, will have the opposite side of 5.0 m and an adjacent side of 12 m.

Calculate θ using the inverse tangent function (also known as arctangent). θ = tan-1(5.0/12).

Perform the calculation using a calculator to find the nearest degree. θ = tan-1(5.0/12) ≈ 22.6°.

Therefore, the smallest angle in the triangle is approximately 22.6 degrees.

Which are the solutions of the quadratic equation?

x2 = 9x + 6



Answers

Final answer:

The solutions of the quadratic equation x^2 = 9x + 6 are (9 + sqrt(105))/2 and (9 - sqrt(105))/2.

Explanation:

To find the solutions of the quadratic equation x^2 = 9x + 6, we can use the quadratic formula. The quadratic formula states that for an equation of the form ax^2 + bx + c = 0, the solutions are given by:

x = (-b +- sqrt(b^2 - 4ac)) / (2a)

In this case, a = 1, b = -9, and c = -6. Plugging in these values, we get:

x = (-(-9) +- sqrt((-9)^2 - 4(1)(-6))) / (2(1))

Simplifying further:

x = (9 +- sqrt(81 + 24)) / 2

x = (9 +- sqrt(105)) / 2

So the solutions of the quadratic equation x^2 = 9x + 6 are:

x = (9 + sqrt(105)) / 2

x = (9 - sqrt(105)) / 2

Explanation:

The given quadratic equation is x² = 9x + 6. To find the solutions of the quadratic equation, we first move all the terms to one side. This gives us: x² - 9x - 6 = 0. This is now a standard quadratic equation, and can be solved by either factoring or using the Quadratic Formula.  

If we opt to solve via factoring, we're looking to factorize the original expression into two binomial expressions, essentially looking for two numbers which both add up to -9 and multiply to -6. These two numbers are -3 and 6. Therefore, the quadratic equation can be factored as follows: (x - 3)(x - 6) = 0. Setting each factor equal to 0 gives the possible solutions for x, in this case, x = 3 and x = 6.

A college professor noted that the grades of his students in an introductory statistics class were normally distributed with a mean of 76.5 and a standard deviation of 9. if 67.36% of his students received grades of c or above, what is the minimum score of those students receiving a grade of at least a c?

Answers

Final answer:

Using the properties of normal distribution and the Z-score related to the given percentile, it can be inferred that the minimum grade for a 'C' in this college statistics class is approximately 72.

Explanation:

In this scenario, the professor's grades reflect a normal distribution, therefore, we can utilize the properties of normal distribution to answer your question. The probability given, 67.36%, corresponds to a Z-score of -0.45 (you can find this in standard statistical tables).

We'll utilize the formula Z = (X - μ) / σ, Z is the Z-score, X is the data point, μ is the mean, and σ is the standard deviation. Therefore, if we rearrange the formula to find X (the data point,or in this case, the lowest grades for students receiving a C or above), it will be X = Z * σ + μ. Substituting the given values in the equation gives X = -0.45 * 9 + 76.5. This results in a minimum score approximately equal to 72.45, or 72 if we consider only whole marks. Hence, our conclusion that the minimum grade for a 'C' is 72.

The minimum score required to receive at least a grade of C in this normally distributed class is approximately 72.54.

To determine the minimum score that students need to receive at least a grade of C in a class where grades are normally distributed, we analyze the problem with a mean [tex](\mu)[/tex] of 76.5 and a standard deviation [tex](\sigma)[/tex] of 9.

We know that 67.36% of the students received a grade of C or above.

This corresponds to the top 67.36% of the distribution.

The bottom 32.64% of the distribution received less than a C.

The z-score associated with the 32.64th percentile can be found using z-tables or a standard normal distribution calculator:

z = -0.44

Next, we convert this z-score to the actual score using the formula:

[tex]X = \mu + z\cdot \sigma[/tex]

Substituting the given values:

X = 76.5 + (-0.44 * 9) = 76.5 - 3.96 = 72.54

Thus, the minimum score required for a grade of at least C is approximately 72.54.
