Find the length of a rectangular lot with a perimeter of 120 meters if the length is 6 meters more than the width

Answers

Answer:

The length is 33 and the Width is 27.

Step-by-step explanation:

So I made it easier by only looking at half of the rectangle. 120 divided by 2 is 60. So out of the length and width, it had to add to equal 60. I plugged in a few numbers and determined 27 and 33. SO, if you add those together it equals 60 while 33 is 6 more meters than 27 and two 27 and two 33 equals 120 for the whole rectangle

Can someone answer questions 8-14 asap and show their work on a piece of paper thanks

Answers

8. So here, you know the angle of elevation and the adjacent, and you're looking for the opposite. So first, put the angle into a tan calculator, because tan is the opposite/adjacent.

What you get is 8.64 ish.

So now, since you know the adjacent, just multiply the two together. 

8.64 * 20 = 172.8, or about 173.

9. a.  You can use the pythagorean's theorem to find this, or a ^ 2 + b ^ 2 = c ^ 2.

Basically, as long as you know the two legs' lengths in a right triangle, or a and b, you can find the hypotenuse, or c.

The two legs' lengths are 35 and 58.

So 35 ^ 2 + 58 ^ 2 = c ^ 2

1225 + 3364 = c ^ 2

4589 = c ^ 2

Then, you can square root both sides

[tex] \sqrt{4589} [/tex] = c

About 68 = c

68 km

b. To do this, just divide the two together, to find the ratio of opposite / hypotenuse (sin), or 58 / 68, which equals about 0.85

Put that in the sin ^ -1 in a calculator to get about 58.211, or 58 degrees.

10. I'm sure there's a more efficient way to do this that I don't know about but I'm stupid. 

a. Whelp, me not knowing how to find the angle of indication/elevation leads to me just using tan because why not. 3.83 is about the answer, or 4.

b. Just multiply 15 by 15, to get 225 m.

11. umm, is there a b to this question?

a: sorry I don't know how to do this one :(

12. a. pythagorean's theorem, a ^ 2 + b ^ 2 = 5.6 ^ 2

Or a ^ 2 + b ^ 2 = 31.36

Since a = b,

a ^ 2 + a ^ 2 = 31.36

[tex]2a^{2} [/tex] = 31.36

/2                             /2

a ^ 2 = 15.68

a = [tex] \sqrt{15.68} [/tex]

about 3.96 = a

3.96 + 3.96 + 5.6 = 13.52

b. Use sin here. 28 degrees in one of those sin calculators is 0.47.

That means the opposite / hypotenuse = 0.47.

So just multiply 0.47 by the hypotenuse, or 10.7, to get about 5.

So the short side of the rectangle is 5.

So you can either do the same with cosine or use the pythagorean's theorem. Either way, you should get about 9.4.

So the perimeter is 5 + 5 + 9.4 + 9.4 = 28.8 (ish)

13. To find the outside length of one of the four triangles or the hypotenuse, since you know the opposite, use sine. Sine is opposite / hypotenuse. 50 degrees in a sin thing is about 0.77. So that means 1.4 / hypotenuse = 0.77, or 1.4 / 0.77, which equals about 1.82.

So the length of the hypotenuse is about 1.82. That times 4 is 7.28, or about 7.3.

14. I'm sorry I don't know how to do this one, I can try tho :(

The stage manager of a school play creates a rectangular acting area of 42 square yards. String lights will outline the acting area. To the nearest whole number, how many yards of string lights does the manager need to enclose this area?

Answers

Length of the rectangular acting area be x.Width = 42 / xWe asked to find the perimeter ( the number of yard that are needed to enclose the area)P = 2(length + width)    = 2(x + 42/x)   = 2x + 84/x
The perimeter is minimum when the differentiation is equal to 0.2 - 84/x^2 = 02x^2 - 84 = 0x^2 = 42 x = 6.48
Thus, the minimum yards of string lights the manager need to enclose the area is  2(6.48) + 84 / 6.48^2 = 12.96 + 12.96 = 25.92 so it is approximately 26 yards


solve the system of equations {3x-y=6 { 6x+y=21 explain the steps on how to do this please

Answers

I would set the equations on top of each other and subtract

6x+y=21
- 3x-y=6
________
3x=15

Then solve for x
X=5

To solve for y, plug 5 in for x for one of the equations
The easiest way to solve this is by elimination. 

3x - y = 6 
6x + y = 21

Since you have a negative and positive y with the same coefficients (1), they cancel, and you add the other terms so it would look like:

9x = 27 

Then solving for x leaves you with x = 3 

Then you take the x value of three and plug it into to either of the equations, so 

3(3) - y = 6

9 - y = 6 

subtracting 9 

-y = -3 

then dividing by -1 

y = 3 

so the solution is x = 3 y = 3 or (3,3) 

Which of the following is an advantage to using tables? A.Tables make the most difficult problems much easier. B.Tables can help to see patterns in data. C.All problems require tables to solve them.

Answers

The answer is B:Tables can help to see patterns in data.

Final answer:

The correct answer is that tables can help to identify patterns in complex data sets, particularly when multiple variables are involved. They provide a linear organization that simplifies finding specific data points and can facilitate the calculation of conditional probabilities in regard to dependent variables.

Explanation:

Selecting the correct advantage of using tables among the given options, the correct response would be option B: Tables can help to see patterns in data. Tables are indeed important tools when dealing with data and statistical information. They organize data in a linear way, making it easier to locate specific points. They're capable of breaking down complex data points that might be hard to convey through written explanation or through other graphical data representation formats.

Furthermore, tables are particularly useful when displaying data associated with multiple variables - for example in Contingency Tables or Two-way tables. These tables simplify the process of calculating probabilities, especially when the variables involved are dependent on each other. These tables can facilitate calculating conditional probabilities easily by decisively organizing the data.

While tables are advantageous in their own right, it's not accurate to say, as in option A, that they automatically make the most difficult problems much easier, nor, as in option C, that all problems require tables to solve them. Instead, they represent a powerful, but specific tool among many others available for data analysis.

ABCD is a parallelogram. A is the point (2,5), B is the point (8,8) and the diagonals intersect at (3.5, 2.5). What are the coordinates of C and D? How do I work this out?

Answers

Midpoint of diagonals: [tex]\( (3.5, 2.5) \)[/tex]. Using midpoint formula, [tex]\( C(5, 0) \) and \( D(-1, -3) \)[/tex].

Since [tex]\(ABCD\)[/tex] is a parallelogram, its diagonals bisect each other. So, the midpoint of the diagonals gives the center of the parallelogram, which is the midpoint of [tex]\(AC\) and \(BD\)[/tex].

Given that the midpoint of the diagonals is [tex]\((3.5, 2.5)\)[/tex], we can find the midpoint of [tex]\(AC\) and \(BD\)[/tex].

The midpoint formula is given by [tex]\(\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)\).[/tex]

For the midpoint of [tex]\(AC\)[/tex]:

[tex]\[\left(\frac{2+x_C}{2}, \frac{5+y_C}{2}\right) = (3.5, 2.5)\][/tex]

From this, we get:

[tex]\[2+x_C = 7 \quad \text{and} \quad 5+y_C = 5\][/tex]

which gives [tex]\(x_C = 5\) and \(y_C = 0\)[/tex].

For the midpoint of \(BD\):

[tex]\[\left(\frac{8+x_D}{2}, \frac{8+y_D}{2}\right) = (3.5, 2.5)\][/tex]

This yields:

[tex]\[8+x_D = 7 \quad \text{and} \quad 8+y_D = 5\][/tex]

which results in [tex]\(x_D = -1\) and \(y_D = -3\)[/tex].

So, the coordinates of [tex]\(C\) are \((5, 0)\)[/tex] and the coordinates of [tex]\(D\) are \((-1, -3)\)[/tex].

If f(x)= x^2-25 and g(x)= x-5, what is the domain of (f/g) (x)

Answers

The domain of the compound function (f/g)(x) is all real numbers except x = 5, where the function g(x) would cause a division by zero.

To find the domain of the compound function (f/g)(x), we need to consider the domains of both f(x) and g(x), as well as where g(x) is not equal to zero, since we cannot divide by zero.

The function f(x) = x^2 - 25 is a quadratic function and its domain is all real numbers because a quadratic function is defined for every real number.

The function g(x) = x - 5 is a linear function, and its domain is also all real numbers. However, for the quotient (f/g)(x), we must exclude the value where g(x) = 0. Solving g(x) = 0 gives us the value x = 5.

Therefore, the domain of (f/g)(x) is all real numbers except x = 5, since at x = 5, the denominator g(x) would be zero, making the division undefined.

A _______ is a set of characters that uses the same typeface.

Answers

Final answer:

A font is a complete set of characters with the same typeface or design, crucial for typographic identity in various industries. Typefaces can be serif, conveying classical vibes, or sans serif, appearing modern. Digital advancements have made typefaces more accessible and diverse for designers.

Explanation:

Understanding Typeface in Typography

A font is a complete set of characters that uses the same typeface or design. This uniformity is a vital aspect of typographic identity and conveys different meanings and vibes, which can be crucial to a corporate image, for instance. The selection of an appropriate typeface is influenced by its use case; businesses might choose a typeface that reflects their industry and brand values. The character of a font can be greatly affected by factors such as whether it is serif or sans serif. A serif typeface, which includes small decorative lines at the end of the strokes that form the letters, like Times New Roman or Garamond, often conveys a classical or refined feeling. In contrast, sans serif typefaces, like Helvetica, lack these lines and therefore appear more modern.

The evolution from physical typesetting to digital design has vastly increased the availability and variety of typefaces, making them accessible and affordable, some even for free. In addition, digital typefaces can be created and distributed worldwide with minimal cost. This evolution has led to a proliferation of typefaces for designers to choose from in creating distinct and visually engaging texts.

Alright, so we have 3.69/0.3. What I personally like to do is expand it so we have whole numbers, so we can multiply the equation by 100/100 to get 
369/30. 


and we know that 30 goes into 300 10 times due to that you simply add another 0. After that, we're left with 369-300=69. We know that 30*2=60, and 69-60=9. Therefore, we can add the 10 and the 2 up to get 12, and the remainder is therefore 9.

Answers

Final answer:

Truman took approximately 51 minutes to get to work.

Explanation:

To calculate the total time it took Truman to travel to work, we need to consider the time he waited for the bus and the time it took to travel the distance.



Truman waited 11 minutes for the bus.The distance traveled on the bus is 21.78 miles.Truman's speed on the bus was 33 miles per hour.To calculate the time taken to travel the distance, we can use the formula:

Time = Distance / Speed

Time taken to travel = 21.78 miles / 33 miles per hourThis gives us a total of approximately 0.66 hours.To convert the time to minutes, we multiply by 60 (since there are 60 minutes in 1 hour), which gives us approximately 40 minutes.Adding the 11 minutes Truman waited for the bus, the total time passed from the time Truman left for work to the time he arrived at work is approximately 51 minutes.
