What is 58.65 divided by 6.9

Answer:

3/9

Step-by-step explanation:

15*4= 60 so 15/60 is equivalent to 1/4.

1/16 is just a smaller equivalent of 2/8 which is just a smaller equivaent of 1/4.

3/9 simplified is 1/3. I/s is bigger than 1/4.

Hope this helps

Answer:

3/9

Step-by-step explanation:

[tex]\frac{1}{4}\cdot\frac{4}{4}=\frac{4}{16}\\\\\frac{1}{4}\cdot\frac{2}{2}=\frac{2}{8}\\\\\frac{1}{4}\cdot\frac{15}{15}=\frac{15}{60}[/tex]

We can turn 1/4 into all of the first three fractions by multiplying it by some version of 1, but we can't do the same for 3/9: trying to multiply 1/4 by 3/3 will get us a different fraction: 3/12. Additionally, 3/9 in lowest form is 1/3, and 1/3 is clearly not equal to 1/4.

Answer: 42

Step-by-step explanation:

First you have to subtract 450 from 6750 to get 6300

Second you have to figure out how many tax returns you have to make by dividing 6300 by 14 to get 450

Third you have to do 6300 / 42 to get 150 so if you times 150x 42 equals 6300.

[tex]75.96^{\circ}[/tex]

Step-by-step explanation:

La función es

[tex]f(x)=x^2-8x+16[/tex]

La derivada de la ecuación nos da la tangente

[tex]f'(x)=2x-8[/tex]

El punto es [tex](6,4)[/tex]

Entonces en [tex]x=6[/tex]

[tex]f'(6)=2\times 6-8=4[/tex]

La pendiente de la tangente es [tex]4[/tex].

El ángulo de la pendiente está dado por

[tex]\tan\theta=m\\\Rightarrow \theta=\tan{-1}m\\\Rightarrow \theta=\tan^{-1}4\\\Rightarrow \theta=75.96^{\circ}[/tex]

El ángulo que forma la tangente con el eje x positivo es [tex]75.96^{\circ}[/tex]

Answer:

3a+33

Step-by-step explanation:

Add 2a+1 to a+32

Answer:

a = 3, b = 1, c = - 3

Step-by-step explanation:

Substitute n = 1, 2, 3 into the n th term

a + b + c = 1 → (1)

4a + 2b + c = 11 → (2)

9a + 3b + c = 27 → (3)

Subtract (1) from (2) term by term to eliminate c

Subtract (2) from (3) term by term to eliminate c

3a + b = 10 → (4)

5a + b = 16 → (5)

Subtract (4) from (5) term by term to eliminate b

2a = 6 ( divide both sides by 2 )

a = 3

Substitute a = 3 into (4) and evaluate for b

3(3) + b = 10

9 + b = 10 ( subtract 9 from both sides )

b = 1

Substitute a = 3, b = 1 into (1) and evaluate for c

3 + 1 + c = 1

4 + c = 1 ( subtract 4 from both sides )

c = - 3

Then a = 3, b = 1 and c = - 3

The measure of a, b and c is  3, 1 and - 3 respectively.

A quadratic sequence is a sequence whose nth term is given by the general formula -

A{n} = an² + bn + c.

Given are the 4 terms of the quadratic sequence as 1, 11, 27 and 49.

Now, we can the following equations as -

A{1} = a + b + c = 1

a + b + c = 1

c = 1 - a - b              ........ Eq[1]

A{2} = 4a + 2b + c = 11

4a + 2b + c = 11

c = 11 - 4a - 2b           ........ Eq[2]

A{3} = 9a + 3b + c = 27

9a + 3b + c = 27

c = 27 - 9a - 3b               ........ Eq[3]

A{4} = 16a + 4b + c = 49

16a + 4b + c = 49

c = 49 - 16a - 4b             ........ Eq[4]

Equate Eq[1] and Eq[2] -

1 - a - b  =  11 - 4a - 2b  

1 - 11 = - 4a - 2b + a + b

- 10 = - 3a - b

3a + b = 10                ........... Eq[5]

Equate Eq[3] and Eq[4] -

27 - 9a - 3b = 49 - 16a - 4b  

- 9a - 3b + 16a + 4b = 49 - 27

7a + b = 22          .......... Eq[6]

We can write -

7a + 10 - 3a = 22

4a + 10 = 22

4a = 12

a = 3

and

b = 10 - 3a

b = 10 - 9

b = 1

At last -

c = 1 - a - b

c = 1 - 3 - 1

c = - 3

Therefore, the measure of a, b and c is  3, 1 and - 3 respectively.

Answer:

Step-by-step explanation:

Answer:

The missing angle I believe is 25%.

Step-by-step explanation:

180-130=50

Divide 50 by 2 and it equals 25. 25 degrees for each angles.

Answer:25

Step-by-step explanation:

alright so the triangle theorem states that all of the angles of a triangle add up to 180. we already of 130 so we take away 130 from 180 to get 50. If you see the two little lines on the triangles sides opposite of the two angles that we are missing then you can tell by those lines that the angles opposite of them are equal to each other. So you divide 2 from 50 to get 25 which is the value of x. Hope you understand this (:

Answer:

The values of [tex]r_{2}[/tex] and [tex]\alpha_{2}[/tex] are 2 and 150º.

Step-by-step explanation:

The complete statement is:

Find [tex]\alpha_{2}[/tex] and [tex]r_{2}[/tex] such that  [tex]\sin \theta - \sqrt{3}\cdot \cos \theta = r_{2}\cdot \cos (\theta - \alpha_{2})[/tex].

We proceed to use the following trigonometric identity:

[tex]\cos (\theta - \alpha_{2}) = \cos \theta \cdot \cos \alpha_{2} +\sin \theta \cdot \sin \alpha_{2}[/tex] (1)

[tex]\sin \theta -\sqrt{3}\cdot \cos \theta = r_{2}\cdot \cos \theta \cdot \cos \alpha_{2}+r_{2}\cdot \sin \theta \cdot \sin \alpha_{2}[/tex]

By direct comparison we derive these expressions:

[tex]r_{2}\cdot \sin \alpha_{2} = 1[/tex] (2)

[tex]r_{2}\cdot \cos \alpha_{2} = -\sqrt{3}[/tex] (3)

By dividing (2) by (3), we have the following formula:

[tex]\tan \alpha_{2} = -\frac{1}{\sqrt{3}}[/tex]

[tex]\tan \alpha_{2} = -\frac{\sqrt{3}}{3}[/tex]

The tangent function is negative at second and fourth quadrants. That is:

[tex]\alpha_{2} = \tan^{-1} \left(-\frac{\sqrt{3}}{3} \right)[/tex]

There are at least two solutions:

[tex]\alpha_{2,1} = 150^{\circ}[/tex], [tex]\alpha_{2,2} = 330^{\circ}[/tex]

And the value of [tex]r_{2}[/tex]:

[tex]r_{2}^{2}\cdot \sin^{2}\alpha_{2} + r_{2}^{2}\cdot \cos^{2}\alpha_{2} = 4[/tex]

[tex]r_{2}^{2} = 4[/tex]

[tex]r_{2} = 2[/tex]

The values of [tex]r_{2}[/tex] and [tex]\alpha_{2}[/tex] are 2 and 150º.

Step-by-step explanation:

The cost to buy the rectangular window is $ 912.60

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the cost to buy rectangular window be represented as A

Now , the value of A is

The length of the rectangular window be L = 10 feet

The width of the rectangular window be W = 13 feet

Let the cost per square foot be c = $ 7.02

Area of Rectangle = Length x Width

Substituting the values in the equation , we get

Area of rectangular window = 10 x 13 = 130 feet²

The cost to buy the rectangular window A = 130 x cost per square foot

Substituting the values in the equation , we get

The cost to buy the rectangular window A = 130 x 7.02

The cost to buy the rectangular window A = $ 912.60

Hence , the cost to buy the window is $ 912.60

Answer:

x=0

Step-by-step explanation:

We can first add 49 to both sides to get (x+7)^2=49

We can then take the square root of both sides and get x+7=7

Subtract 7 to both sides and you get x=0

Answer:

[tex]x=-14\text{ and } x=0[/tex]

Step-by-step explanation:

We are given:

[tex](x+7)^2-49=0[/tex]

And we want to solve for x.

First, we can add 49 to both sides:

[tex](x+7)^2=49[/tex]

Now, we can take the square root of both sides. Since we are taking an even root, we will need plus-minus. Hence:

[tex]x+7=\pm\sqrt{49}[/tex]

Evaluate:

[tex]x+7=\pm7[/tex]

Subtract 7 from both sides:

[tex]x=-7\pm7[/tex]

So, we have two solutions:

[tex]x=-7+7\text{ and } x=-7-7[/tex]

Evaluate:

[tex]x=0\text{ and } x=-14[/tex]

So, from least to greatest, our solutions are:

[tex]x=-14\text{ and } x=0[/tex]

The Geometric Mean (GM) in mathematics is the average value or mean that, by calculating the product of the values of the set of numbers, denotes the central tendency of the numbers. In essence, we multiply the numbers together and calculate their nth root, where n is the total number of data values.

here, we have,

We are given two numbers as 45 and 15​.

Formula for geometric mean is

G.M = √x₁ × ... × xₐ
