The value of the n is 64.04 after applying the tan ratio which is opposite to adjacent (TOA)

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a right angle triangle shown in the picture.

We can use SOHCAHTOA to find the unknown length.

Using the ratio of tan which is opposite to adjacent (TOA)

tan8 = 9/n

n = 64.038 ≈ 64.04

Thus, the value of the n is 64.04 after applying the tan ratio which is opposite to adjacent (TOA)

1) If we let the lengths of the legs be x and 2x, then by the Pythagorean theorem,

[tex]x+2x+\sqrt{x^{2}+(2x)^{2}}=28\\3x+x\sqrt{5}=28\\x(3+\sqrt{5})=28\\x=\frac{28}{3+\sqrt{5}} \cdot \frac{3-\sqrt{5}}{3-\sqrt{5}}=21-7\sqrt{5}[/tex]

This means that the length of the hypotenuse is:

[tex]\sqrt{5}(21-7\sqrt{5})=\boxed{21\sqrt{5}-35}[/tex]

4) [tex]\frac{\pi}{6}[/tex]

Answer:

The symbol is a variable called x, which is a mathematical term used to substitute values in mostly linear and quadratic equations.

Answer:

a term.

Step-by-step explanation:

(I'm assuming you're asking about the underlined,)

therefore the 9x is a term

(top line)

the 9 is a coefficient

the x is a variable

5 is a constant

- (subtraction sign) is the operator.

9x - 5 is an expression

(bottom line)

the 3x is also a term

x is the variable

3 is a coefficient

4 is the constant

the + (addition sign) is the operator

3x + 4 is the expression.

the answer would be a constant and a term

The vertex of the graph moves to a point twice as far from the y-axis.

Option B is the right answer.

The general equation of a parabola is

y = a(x-h)² + k

or

x = a(y-k)² +h

where (h,k) denotes the vertex.

It is given in the question that the value of h is doubled for the equation given

y = a(x-h)² + k

if the value of the h is doubled, the vertex of the graph shifts and shifts on the x axis away from the y axis , therefore

the vertex of the graph moves to a point twice as far from the y-axis.

Option B is the right answer.

Answer: An even number between 7 and 16 would be 10.

Step-by-step explanation: I am not sure how I am supposed to draw a picture of the number other than drawing the number itself. However, 10 is an even number because it is a composite number and is divisible by 2. 10 is an even number, not an odd number. Hope this helps!

Answer:

R s. 36

Step-by-step explanation:

1kg ⇒ 1000g

So, a quarter kilogram means,

[tex]\frac{1}{4}[/tex] × 1kg = 1000g ×  [tex]\frac{1}{4}[/tex]

[tex]\frac{1}{4}[/tex] × 1kg = 250g

According to the question,

250g = R s. 60

So, now they're asking for the price of 150g.

Let that price be x.

250g ⇒ R s. 60

150g  ⇒ x

Use cross multiplication to find the value of x.

250x = 60 × 150

250x = 9000

Divide both sides by 250.

x = R s. 36

Step-by-step explanation:

3.75 quarts of paint does Argelis have left with her.

A unit of volume for measuring liquids. 1 gallon = 4 quarts = 8 pints = 16 cups = 128 fluid ounces.

Here, we know that,

1 gallons = 4 quarts

so, 1/2 gallons = 1/2 X 4 = 2 quarts.

and 1/4 gallons = 1/4 X 4 = 1 quarts.

Now, total paint left with Argelis = 1/2 gallons + 3/4 quarts + 1/4 gallons

                                                     =  2 quarts + 3/4 quarts + 1 quarts

                                                    = 3 quarts + 3/4 quarts

                                                    = 15/4 quarts or 3.75 quarts

Thus, 3.75 quarts of paint does Argelis have left with her.

Answer:

The length is 11ft.

The width is 8ft.

Step-by-step explanation:

Hello!

Perimeter of a rectangle: [tex]P = 2(l + w)[/tex]

We know that the length is 5 ft less than twice the width, which can be expressed by the equation: l = 2w - 5. We can plug in 38 for "P".

We can substitute the equation for l, and solve for the width.

The width is 8. We can solve for the length by plugging it back into the equation l = 2w - 5

The length is 11.

The dimensions are 11 ft and 8 ft.

Answer:

Total people = 240

Step-by-step explanation:

Let the total number of people by 'x'.

[tex]\sf \text{Number of men =$ \dfrac{1}{4}*x$} \\[/tex]

[tex]\sf \text{Number of women =$\dfrac{1}{3}x$}[/tex]

Number of children = 100

When we subtract the total number of men and women from the total people 'x', we get the number of children.

[tex]\sf x - \left(\dfrac{1}{4}x+\dfrac{1}{3}x\right)= 100\\\\x - \left(\dfrac{1*3}{4*3}x+\dfrac{1*4}{3*4}x\right)=100\\\\[/tex]

      [tex]x- \dfrac{4+3}{12}x=100\\\\x - \dfrac{7}{12}x = 100\\\\ \dfrac{12}{12}x-\dfrac{7}{12}x = 100\\\\ \dfrac{5}{12}x=100\\[/tex]

          [tex]\sf x = 100*\dfrac{12}{5}\\[/tex]

Answer:

A. [tex]12x^{4} -4x^{3} +3x^{2} +3x+20[/tex]

Step-by-step explanation:

For this problem, we have to combine like terms.

Let's look at the equation:

[tex](12x^{4} -4x^{3} +7x+6)+(3x^{2} -4x+14)[/tex]

[tex]12x^{4[/tex], [tex]-4x^{3}[/tex], [tex]3x^{2}[/tex] do not have any other like terms, so we keep all in the final answer.

[tex]7x[/tex] and [tex]-4x[/tex] are like terms, so we combine them. [tex]7x-4x=3x[/tex]

14 and 6 are like terms, so we combine them. 14+6 = 20

Let's put everything into the final equation:

[tex]12x^{4} -4x^{3} +3x^{2} +3x+20[/tex]

So, the final answer is A. [tex]12x^{4} -4x^{3} +3x^{2} +3x+20[/tex]

Answer:

$90,000

Step-by-step explanation:

We can can use substitution for this. First, we need to create two separate problems that represent this situation. The house and the lot together cost 120000, so we can make the equation h+l=120000. We also know that the house is worth 3 lots, so we can make the equation h=3l. Because h=3l, we can substitute for h, making the equation 3l+l=120000, or 4l=120000. To isolate l, we have to divide both sides by 4. If we do that, we get l=30000. Now, we have to substitute to find h. Our new equation is h+30000=120000. To isolate h, we have to subtract 30000 from each side. If we do this, we get h=90000. That's our answer.

Answer:

Next number = 95

Step-by-step explanation:

Hi! Let me help you out.

_________________

To determine the next number in this sequence, we should determine the common difference.

We can do it like this.

[tex]\longmapsto\sf 76-57=19[/tex]

See. I took the third term, and subtracted the second term from it.

Continue.

[tex]\longmapsto\sf 57-38=19[/tex]

                                              ↪

The number we obtain after subtracting is the common difference.

So we should take the third term, "76", and add the common difference, "19" to it.

We obtain 95. Which is the final answer.
