Answer:

An ordinary angle is a measure of the length subtended by a one-dimensional subset of the plane. For example, an angle of 60∘ is subtended from a point by a 16 portion of a circle centered at that point. The 16 arc that subtends the angle is a one-dimensional subset of the two-dimensional plane.

Given:

Area of polygon=10.4

sides of polygon=2

Formula for area of a regular polygon= 1/2 (apothem x perimeter )

Putting value, we get

10.4= 1/2 ( a x 12 )

10.4=6a

a=10.4/6

a=1.73

Answer:

x= 45

Step-by-step explanation:

55 +2x+(x-10) =180

2x + x-10 = 125

3x = 135

x=45

Answer:

55 days

Step-by-step explanation:

1 day = 45 minutes

=> x days = 2475 ÷ 45

=> x days = 55 days

Therefore, he had rode 55 days in the whole summer.

Answer:

equation: y= -2x -4

Step-by-step explanation:

slope intercept form is y=m x+b, m being slope and b being the y intercept

Answer:

A. y = | x – 7 |

Step-by-step explanation:

y=|x-7| because in order to go to the right you have to subtract the amount from x

the answer is y=|x-7|

Step-by-step explanation:

we know that the general translation of some equation y=f(x) to the left or right direction by 'a' units is given by y=f(x+a) ; where if 'a' is negative then the translation is in the "right direction" and if 'a' is positive then the translation is in the "left direction".

so in the given question we have the equation y=|x| for it to be translated 7 units in the right the resulting equation is y=|x-7|.

Answer: the first number is 9, the second is 4

Step-by-step explanation:

let n = 1st number

let n-5 = 2nd number

n+(n-5)=13

collect like terms: 2n-5=13

add 5 to both sides

2n=18

divide both sides by 2

n=9

n-5=4

Answer:

21 and 34

Step-by-step explanation:

This is a Fibonacci sequence. Basically, the next term is the sum of the 2 previous terms.

Notice the third term, it's the sum of 2 and 1.

Notice the fourth term, it's the sum of 3 and 2.

Each term follows the same pattern.

Answer:

The value of the x variable is 30.

Step-by-step explanation:

Since the triangles are similar, the corresponding sides of both triangles have a common ratio. The 18:12 ratio of side LK and QR is equal to 2:3, and the 21:14 ratio of sides JL and PQ is also equal to 2:3. Based on this, we know that 2/3 * x = 20, so we isolate the x variable by dividing both sides of the equation by 2/3 to get the answer: x = 30.

Answer:

129

Step-by-step explanation:

Following are the calculation to the method value:

Given:

[tex]\cos (xy) = y-1\\\\ x=\frac{\pi}{2} \ \ and \ \ y = 1[/tex]

To find:

[tex]\frac{dy}{dx}=?[/tex]

Solution:

[tex]\to \cos (xy) = y-1\\\\\to \frac{d}{x} \ (\cos xy) = \frac{d}{dx}\ (y-1)\\\\\to -\ ( \sin xy) \frac{d}{dx} \ (xy) = \frac{dy}{dx}\\\\\to -\ ( \sin xy) ( x\ \frac{d}{dx} + y) = \frac{dy}{dx}\\\\\to - x \sin (xy) \ \frac{dy}{dx} -y\sin (xy) =\frac{dy}{dx}\\\\\to \frac{dy}{dx} (1+ x \sin \ xy) = - y \sin xy\\\\\to \frac{dy}{dx}=\frac{-y \sin xy}{1+x\sin xy }\\\\[/tex]

When [tex]\ x=\frac{\pi }{2} \ \ \ and \ \ \ y=1\\\\[/tex]

[tex]\to \frac{dy}{dx}=\frac{- 1 \sin (\frac{\pi }{2})}{1+ \frac{\pi }{2} \sin \frac{\pi }{2} }\\\\\to \frac{dy}{dx}=\frac{- 1 }{1+ \frac{\pi }{2} } = \frac{-1 }{\frac{2+\pi }{2}}\\\\\to \frac{dy}{dx}=\frac{-2}{2+\pi }\\\\[/tex]

Answer:

4

Step-by-step explanation:

So, since we already know x = 1, we just need to figure out what 3 x 1 is. (Since there's no space between the 3 and the x, 3x would be 3 times x.)

3 x 1 = 3.

So, our "new equation" is:

1 + 3

Add them together to find the answer:

1 + 3 = 4

4 is your answer.

Hope this helps and have a nice day!

Answer:

There is no difference.

Step-by-step explanation:

All whole numbers can be written as fraction, so you would just use the same formula for the fraction as a whole number.

For example:

The whole number 6 can be written as 6/1. We can divide 6/1 by 3/7 by finding the inverse of 3/7 which is 7/3. Then, it is just easy multiplication.

6/1 X 7/3=42/3=14

There is no different for divinding fractions by fractions and you can use the same formula.
